Equipment, examples, history – all matters photographic
This short video on climate change, produced by Toronto Star photographer Lucas Oleniuk, is very elegant. It doesn’t have a great deal of substantive content, but it includes a lot of striking visual images. Rather than being shot continuously, it consists of 20,000 black and white still images.
The video, and some of the claims made in it, are being discussed on Metafilter.
Adobe has released a free web-based version of their most popular image editing program, called Photoshop Express. The software allows for a number of fairly basic modifications, including cropping, exposure correction, saturation and white balance changes, and sharpening. One nice touch is that it does allow the conversion of images to black and white using any of several virtual colour filters. The free service includes two gigabytes of storage, and seems to include mechanisms for integrating with Facebook, Photobucket, and Picasa.
The web version has nothing on the full version of Photoshop – lacking tools like levels and curves, not to mention paths, masking and the thousands of other things that make Photoshop so versatile. That said, it’s a nice thing to be able to use in a pinch, when nothing more capable is readily available.
What do people think about the big thumbnail images in the last few posts? They do allow for a much better sense of the overall picture, and they don’t sit awkwardly to one side of a white space. At the same time, they seem to diminish the text – especially when you cannot see the beginning of a post without scrolling down.
Should I stick with 450 pixel thumbnails or revert to 320 pixel ones?
Canon’s point and shoot digital cameras have many features to recommend them. Among the most important is the intelligent design of the controls. Critical things like exposure compensation, white balance, and flash status can be altered intuitively. The single setting I change most often is probably ISO (the sensitivity of the sensor). You want it to be as low as possible (to avoid graininess) but high enough to avoid blur from subject or camera shake. If you are working in changing light conditions, this is a balance that changes all the time.
One neat thing I discovered is that the A570 lets you program one of the buttons to be a one-touch shortcut to something you do very often. To do so, follow these steps:
Now, pressing the button in the upper right corner below the printer icon becomes a quick shortcut to whichever you do most often. It might only save a fraction of a second each time, but it amounts to a very worthwhile convenience in the long run.
Nothing photographic is my friend these days. The camera I sent back to Canon for repair (because it had a defective battery hatch when I bought it) seems to have come back with a new fault: it eats through batteries in minutes, managing at most five photos before giving out. Some brand new alkaline AAs I put in weren’t sufficient for it to take a single photo. If this doesn’t magically clear up in the next day or so, I suppose I will have to mail it to Canon for another repair.
Compounding the trouble, iPhoto deleted several thousand carefully tagged and sorted images from my library; more than a year’s worth of photography simply vanished. I do have a backup on an external HD (quite current, thanks to the Time Machine feature in Leopard), but I doubt it will be easy to recover them while maintaining the tags and folders.
It’s almost enough to make a person go back to rolls of T-max, binders full of prints, and hours spent in the dark room.
[Update: 11 February 2008] In the end, iPhoto’s little hiccough seems to have cost me every photo I have taken since leaving Vancouver. It was pretty easy to recover the older ones archived by Time Machine. But the photos exclusively on my hard drive just seem to have vanished without explanation. Disk Utility found no problems with the disk or with disk permissions. Once again, the importance of backups is demonstrated.
On the camera front, it seems to be responding well to newly charged Ni-MH cells. Probably, the earlier issue was the result of rechargables losing amps while my camera was off getting repaired, combined with a pack of bad alkalines I purchased.
[Update: 12 February 2008] I was wrong. My camera told me that the batteries were dead after 11 photos. When I put the batteries in the charger, they were ready in the time in took to brush my teeth.
Conclusion: the camera must return to Canon once more, with a slightly more subtle but equally crippling issue to be resolved.
[Update: 10 April 2008] iPhoto failed catastrophically again. Thankfully, I was able to fix it using yesterday’s backup.
For nearly a month now, I have been walking around without a decent camera (the one on my phone is too low quality to count). At the outset, I was wondering if it would change the way I looked at the world. It seems plausible that a person carrying a camera might become overly concerned about the possibility of recording experiences and thus become less immersed in the situations themselves. While I think that remains true in some circumstances, I find that the general result of not carrying a camera is simply loss of acuity in sensation. Having a camera forces you to pay more attention to what is happening around you: the quality of the light, the details of natural and man-made objects nearby, brightnesses and distances and angles.
As Tristan and I discussed while he was visiting this weekend, one’s sensitivity extends to include consideration for the kind of equipment being used. You do see a bit differently when you are carrying black and white film than when you are carrying colour; you care more about textures and relative brightnesses and not at all about colour temperature. Probably, there are differences in how you see based on whether you are carrying a camera loaded with 35mm film, one with a small digital sensor, or one with a larger sensor more capable of low-grain performance in low light. It is a bit like Michael Pollan’s description of what happened to his vision when he was collecting mushrooms: our visual systems are quite happy to optimize themselves for the task at hand.
Thankfully, my repaired camera is in the process of being mailed back to me. It is notable that Canon repaired it for free – essentially acknowledging that the problem arose because of a defect in manufacturing. I thus feel vindicated in saying that the Future Shop staff were wrong to reject an exchange, on the basis that I had abused the camera. I won’t be making the mistake of giving them more business anytime soon.
[Update: 31 January 2007] Oh, trumph and celebration! My camera has been returned and seems to be functioning properly. No more photos of the day from weeks past!
Partly because of concerns about archiving digital files in the long term, I am hoping to make prints from some of my digital files. Unfortunately, there is an issue of aspect ratios. My digital photos all have an aspect ratio of 4:3 – different from those used for 4 x 6″, 5 x 7″, and 8 x 10″ photographic prints. I don’t especially want black bands on two sides of each image, and I definitely don’t want them arbitrarily cropped.
Is there anywhere online where I can order digital prints on photographic paper in native digital resolution? Albums capable of holding prints with that aspect ratio would also be required. The alternative – manually cropping hundreds of photos to minimize the unwanted aesthetic effects of switching to the 4 x 6″ format – is something I only want to do as a last resort.
Three days after purchase, the battery hatch on my new camera broke during the course of ordinary use. I opened it to change the batteries and, when I tried to close it again, found that a little plastic bit was bent outwards. Afterwards, it would not close.
Future Shop refused to exchange it for a working one because they said the breakage was my fault. It was a reminder of just how poor their customer service is. The agent doing the return insisted that it had been dropped, even though it looked absolutely perfect aside from the bit that was bent.
The camera is being sent back to Canon for repair under the manufacturer’s warranty. Hopefully, they will simply repair or replace the hinge assembly. Irksomely, it can only be sent back to the store that did the original sale. When it comes back in a few weeks, it will therefore need to be mailed out to me in Ottawa.
[Update: 16 January 2008] More than two weeks after turning in my camera for repair, it remains ‘unprocessed.’ Perhaps, they say, they will be able to tell me the cost of repair within a week.
[Update: 23 January 2007] Apparently, the A570 has been repaired. My mother has kindly offered to pick it up and mail it to me tomorrow.
[Update: 31 January 2007] Oh, trumph and celebration! My camera has been returned and seems to be functioning properly. No more photos of the day from weeks past!
After asking my permission, a group of authors used one of my photos in their book Adrenaline Junkies and Template Zombies: Understanding Patterns of Project Behavior. The photo in question is of a Soviet automobile in the Occupations Museum in Tallinn. I am not sure of the precise context in which it was used, but they have offered to send me a copy.
I will post a photo of the page including my photo when the book arrives. I am generally happy for people to use my photos with permission and proper attribution. The pleasantness of this experience stands in contrast with the unauthorized publication of one of my photos in The Oxford Student.
When I saw a camera markedly superior to the one I have been using for the last two years on sale for about $150, including a 2GB memory card, it seemed that the time to upgrade had arrived. I was drawn to the Canon Powershot A570 mostly because of the image stabilization, which allows sharper photos in lower light. It is also nice that it has ISO ratings going up to 1600 – compared with 400 on my old A510. It remains to be seen how the graininess of the two cameras compares at fast speeds. The controls on the new camera are nearly the same as the old, though it will take a while for them to become as utterly intuitive as the A510 was after its years of valued service.
What surprised me most about the A570 is how pleasantly quick it is. The time lag from pressing the shutter to taking a photo is much shorter. All sorts of other camera operations are faster too; transferring photos to my computer is about three times faster. The Digic III processor is probably responsible for most of that. As you can see from the two linked images, the A570 also seems to blow out highlights less than the A510. Those frequent white patches were one of the most substantial failings of a camera that is excellent overall.
The old camera remains perfectly serviceable. Virtually every picture posted on this blog has been taken with it. It will probably be available at low cost to a friend who will use it well.
[1 January 2008] The camera has passed to Emily Horn. May she use it well.
