I'm a software developer (currently focused on Python), living in Australia (currently focused on Sydney).

I am an on-again/off-again moderator of Skeptics.SE. (I was Pro Tem Moderator, I handed in my diamond when the first elections were held, and then ran in the second elections about a year later.)

comment Why do some lenses cost 10 times as much when the specs are very close?
What does "sagitally" mean? (perhaps link to a definition?). Best I found was "in the direction from dorsal to ventral", which doesn't help.

comment Why don't most cameras support PNG format?
Lack of EXIF data would be "seen as a negative" by photographers? Bah! These young digital photographer whipper-snappers! In my day, photographers used film and knew what a negative really looked like! :-)

comment Why does a higher-end camera body like the Nikon D700 cost so much?
@Marcin, oh I see where we were at odds now. I was talking about technology exclusively used in higher-end cameras. Larger sensors, case-design, customising software, flash interfaces, factory fitout, support processes, etc. For the technology in common, I agree with you. (Note: Still not suggesting that there isn't even MORE R&D involved in getting other features into the smaller footprint of compacts.)

comment Can the slant edge SFR method measure lens resolution greater than the Nyquist limit for the camera sensor?
@Sean, @whuber, please enter your suggestions as answers rather than comments, (see the big text box at the bottom of the page) so they can be voted upon and edited.

comment Why does a higher-end camera body like the Nikon D700 cost so much?
@Marcin, I worded my answer carefully to avoid suggesting that there is more R&D involved in the specialist cameras. Instead, I am arguing R&D costs per unit sold are higher.

comment What's the recommended off camera flash setup for Canon and Sunpak flash combination?
Are you sure that the 430EX II can be triggered by the 40D's pop-up flash? I thought it needed a line-of-sight infra-red signal from a 580EX or similar.

comment Why do images get “corrupted”?
Some computer cases have USB ports on the front and other ones on the back. Whichever side failed, try the other side. Sometimes devices can be strangely sensitive to this, for reasons I cannot explain.

comment Why is 1:1 desirable for a macro lens?
That makes a lot of sense, @Rowland, thank you. I guess the fact that it is just a line in the sand seems like an important part of the answer to the original question.

comment Why is 1:1 desirable for a macro lens?
Sure, but why is "true macro" so special? Imagine 1:0.9 or a 1:1.1 lenses. Both could "truly enlarge and enhance real world detail in print". 1:1 = True Macro seems to be an arbitrary metric, and not intrinsically any more desirable than nearby and/or even more powerful magnifications.

comment Why is 1:1 desirable for a macro lens?
This answer doesn't address the question. What is so special about 1:1? Is it a special milestone? If so, why? If not, do people treat it as one?

comment Etymology of “flash gun”
Wikipedia says: "Speedlite" is a Canon trade name. "Speedlight" is a Ricoh brand name. "The brand names are intended to indicate that strobe flashes produce much shorter and more intense bursts of light than earlier photographic lighting systems, such as flashbulbs, or continuous lamps used in some studio situations." en.wikipedia.org/wiki/Speedlite

comment Why do my photos look better on an iMac?
@Reid, yes, we are agreeing. The Dell desktop can display nice images with the right display. It isn't a fundamental issue with Windows or Dell; it is an issue of which display has been purchased. I am using a nice Dell-branded LCD display which I paid a little more for.

comment Why do my photos look better on an iMac?
Yes, go visit @kacalapy's question. It has something these answers lack: hope and suggestions about how the problem can be fixed. Your desktop can display as well as the iMac, with the right screen.

comment Should I be worried about ownership of photos taken on my camera by others?
Great idea to take the book-end shots to make attribution much harder to dispute. How do you get the photos of you without those someones being involved?

comment Should I be worried about ownership of photos taken on my camera by others?
If you knew the photo was taken by the friend, I have to agree that his permission for the publication needs to be sought. Which doesn't mean you don't get a cut. After all, without your co-operation, he doesn't have any photo at all. One the tricky area is what if you think you took the picture? The other tricky area, it seems to me, is what permissions were implicitly given to you when the transaction was made.

Is that risk high enough to justify to yourself the refusal to lend your camera? (I appreciate this is a subjective question.)

comment Should I be worried about ownership of photos taken on my camera by others?
I added an update to handle the situation where there is an agreement in place. Your girlfriend's situation is quite different to what I was thinking. As to people's personal responsibility for breakages, that comes under the "many other issues" that explicitly ignored.

Agree that photographs of the photographer are unlikely to be disputed. It is the photo after that one, which is the concern.

comment Does a camera tethered draw power over USB?
I ordered a cheap knock-off to the Canon ACK-E2 when I saw the first responses. Arrived before my photo-shoot, and once all the plugs and cables where duct-taped together to stop them falling out, it solved the problem perfectly.

comment What does the Custom White-Balance *icon* represent?
I have accepted this as the answer, because it strikes me as the most plausible. However, I don't know if it is correct. Thanks André.
