Partial Solar Eclipse Astro-Photography


October 24th, 2014 there was a partial solar eclipse at sunset up our way.  I was on the rear deck with the Olympus PEN EPL3 watching it go down.  All shots with the long 300mm zoom lens.



Typical shot data looks like this:
 f/22 1/4000150 mm ISO1000 for the lower light shots and similar settings with wider aperture for the brighter shots – I’d rather everything stay sharp with as big an F stop as I can manage.  No filter, believe it or not.

Bottling Lighting: Long shutter night photography of the sound and fury

Taken on two consecutive summers in 2010 and 2011 using old cameras I can’t remember.  The first two are from 2011 and happened right after sunset with some lingering light in the sky.  The second set are from 2010 and happened several hours after sunset.

Long shutter shots (15-30 seconds) with preset focus and relatively low ISO settings.  All done from a tripod, obviously.

On Bike 360 Video

Originally posted on Tim’s Motorcycle Diaries.

I’ve been messing around with 360° immersive video at work.  One of the best ways to quickly get familiar with the technology is to use it in a difficult circumstance so you can find its limitations.  At work we’re building immersive video to show a virtual walk-through of our school.  If the gimbal and camera we have will work on a motorbike, it’ll work stuck to a kid’s head as they walk through the school.

There are a number of barriers to admission with 4k video and image stabilization.  Fortunately, the 360Fly4k windshield mount I have is so over engineered that it easily handles the weight and motion of the gimbal and camera rig.

I’ve previously done 4k video with the 360Fly4k, but it has a big blind spot on it, so this would be my first true 360 4k video.  The Fly is a tough thing that takes great footage, but I’d describe it more as a 300° camera than a true 360 one.

This 4k 360 camera is the Samsung Gear 360.  I’m running it off the camera because the app won’t run on my Android non-Samsung phone because I guess Samsung don’t want to sell many of these cameras – it’s kind of a jerk move on their part so if these things don’t sell (because you have to have a Samsung phone to access it remotely), then they’re getting what they deserve.

The Gear 360 has a small screen so you can see settings and using the buttons is fairly straightforward, though you’ll find yourself constantly accidentally pressing buttons while you’re handling it.  The Ricoh Theta 360 is still my ergonomic favourite in terms of control and handling, and they just came out with a 4k version of the Theta – perhaps they’ll lend me one to test.

The gimbal is a Moza Guru 360°Camera stabilizer.  The typical gimbal design has weights to the left or right of the camera to keep things balanced, but on a 360 camera that means you’re blocking all sorts of sight lines.  The Moza gimbal is vertically stacked with the weights hanging below, mostly out of sight.  It has a power button and a push button joystick that lets you set shooting modes and centre your camera so it’s looking where you’re going rather that looking down the ‘seams’ between the two cameras.

Most 360 cameras are actually two or more cameras working together.  The resulting footage is then stitched together in software to make an every direction video.  The raw footage from the Samsung looks like this (on left).  A front and back facing fish-eye camera capturing separate footage.

Because both cameras are capturing different scenes, you can often see where they are stitched together because of a difference in ISO which shows up as a clear line of brightness difference (on the right).  They all tend to be identical, fixed-lens cameras, so the aperture and shutter speed tend to be identical.

The first test video has the Samsung camera set at highest resolution (4096×2048 pixels in video) and 24FPS.  The gimbal is in locked mode, so it’s always looking in the same direction even if I go around the corner.  The gimbal provides smooth video by taking the bike’s motion out of the video (it’s always looking in the same direction as the bike and I rotate around the shot), but a bike’s motion is one of the best parts of riding, so for the second shot I set it in tracking mode so it followed the bike’s motions.


Uploading it to YouTube out of the Gear 360 Action Director resulted in a flattened video that doesn’t allow you to pan.  In order to produce that kind of video in the G360-AD (what a ridiculous name), you need to PRODUCE the video in the software and then share it to YouTube from within the program.  My issue with this is that when you bring the program in it takes an Intel i7 VR ready laptop the better part of twenty minutes (for less than ten minutes of footage) to process it before you can do anything with it.  When you produce it (again) for YouTube you end up waiting another twenty minutes.  The Ricoh Theta saves the video (albeit 1080p equivalent) in a fraction of the time and the resulting saved version is 360 ready for YouTube; the 360Fly software is likewise efficient at 4k.  I’m not sure why I have to wait forty minutes to produce less than ten minutes of footage on the Samsung.  I know it’s a lot of data to work through, but it isn’t a very streamlined process.

So, after a lot of post processing, the 4096×2048 360° video out of the camera shows up on YouTube at 1440s (s stands for spherical rather than p – pixels – spherical footage is stretched across a wider area and tends to look less sharp).  I’m not sure where my 2048s footage went – I imagine part of that big post processing was to shrink the footage to fit on YouTube more easily?

If you click on the YouTube logo you can watch it in YouTube and adjust the resolution (bottom right) to see how it looks (make sure to do it full screen to use all your pixels).  If you’re lucky enough to be watching it on a 4k display, this will come close to filling it.

The quality is excellent, the microphone remarkably good (they get beaten up pretty badly on motorcycles), but the awkwardness of post processing and the ergonomics of the thing don’t make it my first choice.  Trying to manage it with gloves on would be even more frustrating.  What you’ve got here is a good piece of hardware let down by some weak product design and software.

The software does offer some interesting post processing options in terms of wacky arts filters, but if you’re shooting at 4k all this does is drastically reduce the quality of your video.  If you’re going to use those filters film at way lower resolution so you don’t have to wait for hours while they process.

I’m aiming to go for a ride tomorrow to look at the fall colours after our first frost.  I’ll bring the Samsung along and see how well it photographs.  It’s promising 15 megapixel 360 images and high dynamic range landscapes, so I’m optimistic.  Photography is timeless and my preferred visual medium anyway, I find video too trapped by the continuity of time.  Maybe the Samsung will be a good photography tool.  Of course, I won’t be able to fire the thing remotely because I don’t have a Samsung phone…

Follow up:

The next morning I set up the camera on the gimbal for the ride to work.  The camera epically failed to catch any of the magic of the morning mist.  The video I got was starting and stopping every minute and the footage was a mess, full or artifacts and unusable.

Compared to the robust Ricoh Theta (which I’ve had out in light rain with no problems) or the bullet proof 360Fly4k, which I’ve left filming through full on storms, the Samsung gave up the ghost at a bit of fog on an otherwise sunny morning.

This is not a tough camera by any stretch.  Dainty might be a better way to describe it.  For something that’s supposed to catch the world around you, it’s best used indoors.  Yes, I’m bitter that I couldn’t catch anything of that glorious morning ground fog.

Simulated image indeed – this camera wouldn’t work that close to an ocean!  If you’re looking for a resilient, tough, outdoor camera, this ain’t it.

Super Moon Astro-Photography

It was a cool, clear night when we had 2017’s December super moon, so photos and video ensued.  The longest lens I’ve got is a fixed Nikon Coolpix P610.  It’s a whole camera that costs a fraction of the equivalent SLR zoom.  Since it’s build to use that lens, even though it doesn’t let a lot of light in, it does a lot better than you think it might.  The photo and video below were taken with the P610 on a tripod at about 8pm once the moon had cleared the horizon.

Last Ride of 2017

A last double digit day before the snows fell meant one last ride at the end of November.  Photos all on the Ricoh Theta 360 camera.  


It’s hard to stay ahead of the dark this late in the year, so some pretty heavy photoshopping happened on these images (the Theta has a fixed lens so only so much light gets in)…

ECOO 2017: building your Edtech house on shifting ground

These are the big 3 that are somehow branding
entire school boards, but the education
software sector is a 10+ billion dollar industry
beyond even them.  Happy to make money
from education, not so happy to pay taxes
to provide that education in the first place.

I attended a panel discussion yesterday a #BIT17 between educators and education IT support that jumped up and down on a number of hot button issues.  One thing that’s always struck me about attending a conference like ECOO is the point of view of the support people in education; they don’t seem to get the support piece.  Our function is to educate.  Not provide PD for teachers, or build an IT network.  Those things are there only to support the main function of what we do: educate children.


In the course of this discussion it was suggested by curriculum support people and board IT professionals that teachers should be spending an inordinate amount of their time closely reviewing the legal documentation around software applications and vetting software.  I thought we had people for that.  Having a teacher do that is akin to pulling all your commandos off the front line in a war and having them do paperwork.


Once I got past everyone who doesn’t work in a classroom earnestly telling me I should be doing their job for them (odd that teachers never suggest that of other education employees), we continued to pursue the topic of heightened responsibility – the term that was used to shut down my suggestion of using your online PD community to source new technology ideas for your classroom.  From my point of view, if a number of educators I know personally suggest trying a new app or other piece of educational technology, that’s a fantastic resource.  I was told by a panel member that this stifles innovation.  I always thought it was a source of innovation.  Perhaps this was a misunderstanding in terminology.  I used the term crowdsource to describe my process of vetting a new piece of software.  To the CIO and curriculum experts on the panel, this meant trusting strangers on the internet.  That isn’t my experience with online learning communities at all, it’s anything but dealing with unsubstantiated strangers.  Maybe that’s how they tentatively work online though.  Let’s call that one lost in translation.


Michelle Solomon from the Association of Media Literacy was on the panel and created an awkward moment when she suggested that using even board/ministry sanctioned software like Turnitin.com (a private, for profit company that uses student data to make its money) was morally ambivalent.  The CIOs and curriculum experts were quickly able to compartmentalize that truth and function again within their fiction, but it knocked the floor out of what we were talking about for me.


When describing themselves and their school boards, the IT people in the room said, “we’re a Google board” and “we’re a Microsoft board” as a means of stating their, what, affiliation?  Their purpose?  You’re public school boards here to promote and deliver public education; what you aren’t is a multi-national media company that undermines democracy and avoids paying taxes anything.


The ‘stop loading malware onto our networks/teachers should be happy with less choice and spend more time pouring over software legalize‘ angle was designed to create a locked down, heavy drag system where innovation and moving with trends in data management would be years behind what everyone else is doing.  I have to wonder just how bad the teachers-installing-malware issue is, because I haven’t heard anything about it.  This invented and absurdly low threshold for software access (watch out, everything might be infected!) then had the blanket of heightened responsibility thrown over it all.  Of course, you know what the answer to all these technically incompetent teachers installing malware is?  Get a corporate system!  Become a Gooplesoft board!


Except, of course, those earnest, well meaning multi-nationals, from their totalitarian labour to expert accountants, aren’t in it for education, they’re in it for money.  You want to talk about malware?  It’s all malware!  Google promises not to advertise to your students while they are in Google Apps for Education, but they can’t stop mining data on what students do in GAFE because Google is a data mining advertising company, it’s how they make their money.  They always serve themselves first.


I left this talk with my head spinning.  I feel like we were talking in circles about a fiction that

doesn’t exist.  We could have a self-built, non-corporate technology foundation for Ontario Education, but it would be hard work and would require technical talent to achieve.  Why do that when we can give in to the hype and Vegas-like allure of the educational technology juggernaut?  Pick your poison, but if you’re going to use educational technology none of it is blameless, it’s all built on shifting grounds undermined by hidden revenue streams.


At one point it was suggested that we need to build media literacy in order to battle this situation.  It needs to start with the educators and technologist working in the industry.  If we’re too busy drinking the koolaid to recognize just how twisted this all is, then there is little hope of graduating students who anything more than consumers.

Stop Trying To Help Me

The other day I was driving my better half’s car.  I don’t usually drive it and it’s still relatively new so each time is an adventure.  It was a busy day on the main street of our village, so I was parallel parking into a spot with a row of traffic lined up behind me.  It’s a smallish vehicle so this is pretty straightforward, or it would be.  Shifting into reverse I backed in to the spot only to have the emergency warning systems start bleeping at me frantically whenever a car passed by.  This system is supposed to be there to make the car safer, but in interrupting my parking process repeatedly it actually kept stopping me because I thought we were about to have an impending impact.  I’d have been better off without the frantic bleeping and would have parked the car more efficiently, quickly and safely without it.

It’s a pretty thing and very efficient for what it is,
but this Buick likes to get in the way of my
driving process.

Pulling out after our stop I backed up to clear the car in front and the mirrors aimed down – I presume to make sure I’m not running over any small animals, but when I started driving forward all I could see out of the wing mirror was the ground, which isn’t very helpful when I’m trying to pull out.  I’d have been better off without the squirrel saving rear view mirrors.  I can always actually move my head if I want to see down through the mirror, it doesn’t need to move at all.  The worst part about all of these interrupting technologies is that in addition to actually making driving more difficult, they are also another thing to break over the life of a car.


I’m all about technology assisting a process, I’m happy to use the rear view camera to make centimeter perfect parking, but there is a big difference between interfering and assisting.  When you’re backing a car up and it starts bleeping at you about impending impacts that aren’t happening it isn’t helping, it’s introducing false and interrupting signal to your process.  When your car aims its mirrors at the ground and then leaves them there thus preventing you from using them to assess incoming threats, they are a hazard rather than a help.


This ‘we’ll do it for you‘ technology sets all sorts of dangerous precedents:




This ad doesn’t make me think, gee, I need a Kia so when I’m operating a two ton vehicle like a clueless git it’ll save me from myself!  It does suggest that there should be far fewer people with valid licenses on the road.  Driver intervention tools like this muddy the line between expectations of driver competence and technology’s ability to take care of things.  How often do educational technologies do the same thing in the classroom?


But what about technology like anti-lock brakes that actually outperform most people in emergency situations?  I pride myself on my ability to modulate brakes very effectively, but modern anti-lock systems are so capable that I can’t keep up, and I consider them a requirement on a modern car.  This isn’t an anti-technology rant, technology should be able to help us do things better, but when it doesn’t it drives me around the bend, and it doesn’t whenever it tries to do too much for us, and especially when it starts to assume responsibility for the very human parts of driving (like paying attention), or the very human parts of learning, like demonstrating skills.


Self driving cars are on the horizon.  For many people this will be a great relief.  Those who hate driving and do it poorly will all be better off for it, and so will the rest of us when they are no longer operating a vehicle.  I have no doubt that for the vast majority self-driving cars will drastically reduce accidents, but they also mean those of us who are willing and capable lose the chance to learn how to do something well.  The fact that I can toss pretty much anything into a parallel parking spot (I did in in a van… in Japan… with the steering on the wrong side) is a point of pride and a skill I took years to develop.  If machines end up doing all the difficult things for us, what’s left for us to do well?  If machines end up demonstrating our learning for us, what’s left for us to learn?


Based on what I’ve seen recently, I’m more worried that machines will unbalance and panic us while they are taking care of us.  I don’t look forward to that future at all.  Perhaps clueless, bad drivers won’t notice any of this and will do what they’re doing now, minus the actually controlling the car part.  Perhaps poor learners will happily let AI write their papers and answer their math quizzes, and never have an idea if what they’re doing for them is right or not.


I often frustrate people by second guessing GPS.  Mainly it’s because I know how hokey the software is that runs it, so I doubt what it’s telling me.  When GPS steers me up a dead end road I’m not surprised.  Maybe I’ll feel better about it when an advanced AI is writing the software and it isn’t full of human programming errors.  When that happens maybe it won’t matter how useless the people are.  There’s a thought.


I’m a big fan of technology support in human action, but it should be used to improve performance, not reduce effort and expectation.  It should especially not damage my ability to operate a vehicle effectively.  The same might be said for educational technology.  If it’s assisting me in becoming a better learner, then I’m all for it, but if it’s replacing me as a learner, or worse, interfering with my ability to learn, then the future is bleak indeed.

October Commutes: A Photo Essay

Along the same stretch of road at 8am each morning as the sun gets less and less.

October 1-5

 Ice forming on the Theta meant very blurry images – Photoshop made them a bit more abstract but less blurry.



Oct 8-12



Oct 16-19 – a thick frost had me stopping and using the phone instead of the Theta…

Six Wheels Across Canada

Crossing Canada (and we’re not even going
coast to coast) isn’t a little trip.

Next summer we’re aiming for the family cross country trip.  If you live anywhere except one of the largest countries in the world that might not require too much forethought, but it takes over 2000kms and 3 days just to get out of the province we live in, then there are another four provinces to cross before getting to the family reunion in British Columbia.  The thought of doing this on a bike is both invigorating and a bit overwhelming, and besides, I’d like to spend some time in the car with everyone soaking up the views together.


What to do?


Is it possible to get a vehicle that would get us across Canada reasonably comfortably but would also allow me to drop two wheels down when the roads demand it?


I’ve had the van itch before, but is there a vehicle that could carry the three of us and a bike well?


Guy Martin’s Transit Van fascination has long been an influence.  It turns out you can buy a special Guy Martin Proper edition these days in the UK.


Choices for North America aren’t that special, but you can still put together a custom enough van that might be the Swiss-Army knife of a vehicle that I’m looking for.  What’s interesting is that on the UK site they talk about using a Transit as your 24/7 vehicle like that could be a thing, but North Americans would find Transits impossible to live with (because North Americans are just too precious?)


The long wheelbase, medium roof Transit will handle four seats with room enough to comfortably swallow a Triumph Speed Triple as well.  With a finished interior it’d be a comfortable way of making the epic cross country trip and could handle all the luggage we could throw at it.


In cross country mode it’d have the four seats in and plenty of room to stretch out and cover big miles.  I’d be tempted to swipe some of the “Proper” Transit and sporty it up a bit, but the main idea would be to have a modern, efficient van that is able to do many things.


With the bike out we’d be able to stretch sleeping bags out in the back, and there are some other interesting options I think I’d explore.  The Aluminess Roof Rack turns the whole roof into a patio, which would be handy on trips for photography, as a base for drone filming operations or as a vantage point when the van is taken to events.  It has a cool LED spot light bar on the front too.


There are a number of interior finishing options available.  I’d take the van to a finished interior, but I don’t know about a private jet on wheels, I’d want it to keep some of its utilitarian appeal.  Being able to rotate the front seats would have obvious benefits though.  A number of companies finish these vans, from use based needs to full on camper conversions.


The medium roof, long wheelbase version of the Transit will take in about 163 inches long in the cargo area – a Triumph Speed Triple is about half that, so it’d fit behind a second row of seats.  Maximum load width is almost 70 inches, the Speed Triple is less than half that wide at the handle bars and much less elsewhere, so it’d fit comfortably on one side of the rear cargo area.  Maximum load height is 72 inches, the Speed Triple is less than 50 inches tall.  Even a big bike like my Tiger (54 inches tall, 34 inches wide, 89 inches long) would still comfortably fit in the Transit.  Since a Transit will take close to 4000lbs in payload, the thing could easily handle a pair of big bikes without breaking a sweat.  One bike, 3 people and a pile of luggage wouldn’t make it break a sweat.




The ten thousand kilometre odyssey across Canada would be a lot more fun with such a comfortable, spacious and capable vehicle… and being about to ride the Rockies and the West Coast west and then back east again would be spectacular.


Almost four thousand kilometres of Rocky Mountains and West Coast?  Magical!  Having a vehicle that can deliver it together AND on two wheels?  Bazinga!

Reflections on Reflections: mastery & expertise and long standing inequalities

The revive old post plugin on WordPress is great (and random) , and gets you re-reading old reflections. Learning Expert and the Skilled Master shone a light on the PD I was about to walk into that morning.

Things keep happening at work that I’ve just had surface online.  The resonance between ideas from years ago and now always makes me wonder about the progression of education.  The more things change the more they stay the same, I suppose.

Last week before our first PD day of the year I was re-reading a three year old post comparing learning experts with skilled mastery (when you’ve been blogging for six years you get to see a lot of old ideas remembered).

Learning experts are like chameleons, perfectly camouflaged by their quick minds.  They’re able to effectively consume large amounts of information and present it effectively in an academic setting.  They’re who you want to explain to you how an internal combustion engine works, but they aren’t who you want fixing one.  Learning experts tend to have a finger in a lot of pies.  They don’t focus on developing a single set of skills because they prefer the rarefied air of pure learning; they tend to be informational creatures.

By contrast the skilled master is someone who has spent a lot of time honing stochastic skills though trial and error in the real world; their’s is a situated intelligence.  They might have an encyclopedic knowledge of their specialty but they tend to shy away from theoretical recitation in favour of relying on personal experience.  Their expertise is in the particular, not the general.  They are able to demonstrate that expertise concretely.  Learning experts shy away from that sort of tangible skills demonstration.

High school teachers are expected to have mastery of their subject area, but you’d be amazed at how many English teachers don’t write and how few science teachers do science.  In fact, in my experience, the vast majority of high school academic specialists don’t practice their specialty in any discernible way.  They come dangerously close to making that annoying Shaw quote look accurate.  One of the exceptions I’ve found is in the technology department where our chefs chef, our technicians repair and our materials experts do carpentry and metal work, every day.  Constant examples of their expertise pop up all over the school.

We spent PD last week doing the learning expert thing as we always do.  We began by being given statistics so laughably incomplete as to be essentially useless and were then asked to suggest sweeping changes to our school based on them.   After being handed a Ministry document so dense in edu-speak as to be practically incomprehensible (which isn’t a problem if tangible results aren’t a requirement), we were asked to apply whatever it was to how our department teaches.  We then spent time touching so lightly on mental health as to barely register our presence before ending the session blasting off into the school as the resident experts on it, ready to develop deep personal connections with all the students who least want that.  In the afternoon we learned how to make our own statistics to justify any course of action we choose.  At the end of the day all the learning experts felt like they’d done many things, I felt like I’d been desperately treading water for eight hours.

Tangibles from the day?  Nooooo.  We don’t do tangibles.


NOTES:

The sub-text of our data driven morning was that our school doesn’t do enough to support our essential and applied students.  Seeing as we’re not sectioned to run those courses and have to squeeze them into existing classes, it’s little wonder they aren’t being served well.  Rather than trying to pry this open with insufficient statistics why not talk to the actual problem (our essential sections are given away to a school miles away)?

Since then there has been some top down pressure on making open courses easier.  Essential and applied students don’t need easier, they need curriculum delivered to their needs.  It’s hard to do that when we prioritize running a dozen half empty grade 12 university bound science courses but barely any non-stacked essential classes.  I’m guessing because these stats weren’t given, but we spend more than half our class sectioning to satisfy university bound academic students who compose less than 30% of our student population.

LINKS:
consumerist learning: less challenging classes aren’t what students are looking for.
proliferation of fifties:  we already pass students we shouldn’t.  How low should we go?
situated intelligence:  it’s the only real kind we have. Everything else is politics.
