Initial experiments with infrared using the Canon 1Ds.
Some notes: this camera seems to be more sensitive to IR than it’s T100 sibling. I have used a variety of processes here to bring out the images, mostly having to do with exposure compensation and sharpening. I can see where some adjustments are needed, for example I was using ISO 1250 (max on the 1Ds) and it is grainy. Most of the images were at f16 to avoid focusing issues. I can see where lower ISO and longer exposure time would be advantageous. Also I am not satisfied with the initial WB setting as the exposure for that is off. Images were taken without a tripod, using fence posts and rails instead. You can see this lens (the 50mm Super Takumar) has a ‘hot spot’ for sure.
Unfortunately I have to start all over because of the limited space on my only CF card. I will keep experimenting until I get results I want, even though my aim for this camera is not IR photography.
It seems I’m not a good photographer. For one thing, I don’t use thousands of dollars’ worth of the latest, most technologically advanced gadgetry. I mean equipment. I don’t shoot RAW and then spend 12 hours fiddling with settings to get everything absolutely perfect. Why, the images I share aren’t even 4X the size of any computer screen out there so you have to pan-and-scan to look at them. And of course after having taken photos for a little over half a century I have no understanding of the use of light, much less knowledge of composition and framing.
Seriously: what the hell do I know about photography?
Well I know how to annoy the hell out of people by doing it my way, I guess.
So here is a larger-than-usual image that I happen to think is a good one, even if it is just another of my endlessly boring “professional snapshots”.
And I’ll warn you in advance I intend to continue doing this, with the occasional ‘feature foto’ thrown in for good measure, until something stops me.
The weather has gone lousy again so it looks like photo shoots stop for a while. Of course it could all turn around tomorrow: it does that at this time of year. Still not clear enough to go to the cabin, but maybe next week? We’ll see.
In the meantime I took a few shots with the 28mm f3.5 Super Takumar on the Canon 1Ds. This is not my favourite lens for this camera. It works fine and is plenty sharp of course, but it doesn’t ‘fit’ right in terms of taking pictures. In fact the lens-body combinations that work best (to my eye) are the 50mm on the full-frame 1Ds, the 35mm on the Pentax K100s, and the 28mm on the Canon T100 (the last two are APS-C sensors with 1.5 and 1.6 crop factors respectively). Not really a surprise as that’s as close to ‘normal’ lens/body combinations as you can get with these equipment choices.
So let’s see the pictures.
A quick on-line check shows the shutter count on this camera is less than 31,000 – which means it will probably outlast me since they are supposedly good to 150k.
I have yet to try this out on night photography due to lack of weather co-operation. We have already got to the point where you have to stay up ’til 10:00 PM to get a truly dark sky, and that will get worse as we near the Summer solstice and get almost 16 hours of daylight!
There are only two things I don’t like about this camera. The first is the weight, which is enough to relegate it to studio-only work. I can’t imagine even a young photographer gaily toting this 3.5 lbs. body plus lenses over hill and dale. Sure, I’ve handled heavier cameras but that was when there was no choice. It makes me wonder if this wasn’t the driving force behind mirrorless design; all for the sake of weight!
The second issue is the controls are pretty badly thought-out. Many of the most-used items (like ISO) are stupidly complex to operate or are in dumb locations. That big turning wheel on the back for selection is absolutely moronic: four simple arrow buttons like everyone else uses would be infinitely better. The major selections for operation are again stupidly done, where a simple PASM dial would be welcome. Even the ON/OFF switch is poorly located. I think no photographer was involved in the design. For my purposes this isn’t a major issue because I usually “set and forget” things in advance – a particular camera has a particular job and doesn’t get altered from the best settings for that job. The exception to this is the ‘experiment’ camera (Canon T100) which suffers all sorts of changes depending on the experiment of the time.
Otherwise I like the larger sensor size for giving exactly what was expected of it. I don’t see it as the miracle solution for bad photography it is often subliminally touted as – by the same people who think more megapixels cures the same problem. I still haven’t tried it for astro or landscape really, and that’s what I really want to do with it. I don’t think I’ll be buying any more lenses for it specifically, other than in so much as the T100 also takes EF lenses.
Struggling to find anything like light around here lately, but at least I did clean the sensor on the Canon 1Ds! These were taken with that camera on manual, using the 35mm f2 Super Takumar.
Okay the landscapes themselves aren’t very good pictures, but there’s nothing wrong with how the camera captures them.
That’s a segment of the full-size image of the berry, by the way. So much for the “11MP is very low resolution” crowd.
Next for this camera I will try the 28mm f3.5 Super Takumar. I am debating buying additional lenses for this camera because I’ve come across a deal on a couple, and I find I like the camera fairly much – aside from the absolutely idiotic controls arrangement. No photographer was consulted on the layout of them, obviously.
I will be ordering a larger CF card because this “ten picture limit” is driving me nuts. I can’t really go out in the field and shoot a “whole roll of film” because of the storage limitations.
Not possible to get out to the cabin yet as snow and ice is still all around and keeps coming back. I have q few pictures taken with the Nikon P610 to share, and a photo shoot ‘job’ to do this week. Who knows; maybe the sun will shine long enough to capture it.
Even though I still haven’t cleaned the sensor on the ‘new’ Canon 1Ds, I have tried a couple more lenses on it. So far I’ve used the two Canon EF lenses I have (40mm and 75-300mm) and the 50mm Pentax Super Takumar. All okay so far.
Now a brief explanation of Canon EF lenses. There are two types: the EF, which has a red alignment dot, and the EF-S which has a white alignment square. Both will fit on a crop-sensor camera such as my Canon T100 (the body of which has both the red dot and the white square), but only the red dot EF lenses work on the full-frame cameras like my Canon 1Ds (which has only the red dot). The EF-S lenses will not fit due to the rear of the lens intruding into the camera body. Don’t try it, you could damage something.
That said, the next lens I tried was my old M42 mount Vivitar 135mm f2.8. It’s a pretty good lens too.
How sharp is it? Here’s a portrait of Marley the usually silly dog:
And now we take a 640×427 segment out of the full frame, right around her eye:
It is not the sharpest lens I own, but it’s hard to fault it. There’s no trickery like ‘unsharp mask’ used here either; it’s all in the lens.
But the lens does have its failings. Of course it’s manual, so that means manual focus and manual exposure. So no quick ‘grab shots’ of anything. Also, for most of the things I shoot the focal length is pretty short:
That is again taking a small segment from the full frame, and the birds are still very small. I even used the unsharp mask to enhance their shape, but no amount of computer processing will make up for the physics. Really: you’ve got to stop believing those TV shows that pretend a satellite in orbit can read a license plate that’s perpendicular to its lens as clearly as if it were ten feet away.
Now back to the EF vs. EF-S issue. I have one more lens in my collection which claims to be EF, in that it has the red alignment dot and will fit the full-frame camera. There’s just one little problem:
This is the 18-200mm Tamron, which also has sharpness issues at any setting. Here we see the vignetting that showed up as a minor thing on the APS-C sensor at the 200mm length becomes full-blown-artistic-whatsit whether you want it or not. Yes you could crop this out, but then you’d notice the blurry focus all the more.
Nope. That lens is not good enough for me. BTW it also focuses noticeably slower than the Canon lenses, and sometimes inaccurately.
I still have the 35mm and 28mm Super Takumars to try on this camera. But first I absolutely will clean the sensor. I promise. Or at least make a try at it.
I also need to get a larger CF card because at full resolution I can only fit 11 images on the 64 MB one I have. That isn’t even a ‘half roll’ equivalent.
One of the cameras I’ve wanted to try is a full frame, any full frame, DSLR. My preference was the Canon 5D, but despite being plentiful they continue to command indecent prices. I’d about given up finding anything when along came this offering from within Canada which eliminated the cross-border hassles. I managed to get it on a last-moment bid for about 1/3 what similar ones are going for and about 1/2 what an in-Canada 5D costs. In all a pretty good deal, especially as it showed up with all the manuals and discs and a firewire cable and three batteries plus charge and an AC adapter! I’m not sure how good all the batteries are as I’ve only managed to get one charged enough to activate the camera.
So, the acid test: how good does it do ‘out of the box’?
Not bad. I was using the slightly fuzzy 75-300mm Canon EF zoom, which on this camera is 75-300mm because it’s full frame! As expected the contrast needed a little help, partly because it was a gray day (heavily overcast) and partly because it’s an old sensor. But I like the colour rendition.
Yes the sensor will need cleaning. Do people never look after their equipment? Mostly the camera looks good with only a few minor scuffs and expected wear. The dirt shows up more on a full-size rendering.
Here we have a 640×427 section of the full-size 4064×2704 frame. It’s a little blurry even with the application of unsharp masking. There are three factors at work here: it’s ‘only’ an 11MP sensor, the lens used is not the sharpest, and the camera has a reputation for being ‘soft’. I have not got into the settings yet to see how much it can be improved on its own.
This shot is cropped square just to eliminate annoying clutter on one side. I’m hoping for some better weather (i.e. sunshine) and a chance to try it out with the 40mm prime lens (it won’t work with the EF-S lenses) and the 50mm f1.4 Super Takumar on manual. That should be something to see!
This is no lightweight camera, btw; it tilts the scales at 1585 grams without a lens. The T100 is only 436 grams. We’re talking three-and-a-half pounds of camera; more than most film SLRs weigh. I don’t expect this to be a ‘daily’ or ‘street’ camera by any means; it is intended for quite specific use which I hope to get to soon.
Until then, I will do such testing as I see fit and can think up.
Welp, it happened: I got slammed with the WordPress Inoperable Version Dumb To The Nth. Fortunately I had this ‘backdoor’ link saved. This when I’m about to pick up my new addition to the tool box today. If this work-around their idiocy fails, that’s it. I do not care to suffer the slings and arrow of outrageous stupidity, nor fools gladly. Or even at all.
For today, then, this “Ditchumentary”: some images I took to document the flooding at the neighbours’ caused by run-off from the hill behind them where illegal logging was done. I doubt they’ll be able to do anything about it.
So many things going wrong here these days. Still no chance of vaccine and the case numbers are rising like crazy because people won’t follow the rules. I did a survey for the hospital visit and it was obviously designed to prove the results they wanted in four areas, three of which had nothing to do with the visit. Have not heard about future consultation, so I guess I just wait until the next emergency.
I’d better go get that package today as I’m feeling pretty nasty and depressed.
… many things. Better weather, consultation with a doctor, shopping trip, and shipments.
But not Godot.
While I’m waiting I tested the Nikon P610’s focus failure, which I noticed is most pronounced close-up and with the lens pointing down. The lens is actually loose in its barrel, and you can feel it (and sometimes hear it) shift around. So I pointed it down and took a close-up of a wild rose stalk, and then gently pushed the loose section back to the camera to ‘take up the slack’. What I found was that the autofocus said it was correct at either point, but the actual focal point was off by about 10mm (at a distance of roughly half a meter). This doesn’t explain why it sometimes fails to focus on more distant objects, except in as much as the internal wear may cause some random slack then as well. I’ll have to devise an experiment to check that. Although there isn’t anything that can be done about it.
Anyway, here’s the best picture from that test. It shows again why I like that camera!
That’s a 640×480 crop out of the full size 4608×3456 image. At the focal point it’s very sharp indeed! Not bad for a $400 ‘bridge’ camera, eh? It will cost me over $700 to replace this ailing imager, so I’m not keen on it quitting altogether. True, the EVF is practically impossible to see at times and the exposure is no longer accurate across all conditions. Yes, the pictures always need a slight contrast improvement because the sensor has aged and doesn’t produce ‘snappy’ results. Okay, once in a while it jams completely and has to be shut down and restarted. But as long as I can coax the images I want out of it I will keep using it.
