I've not done anything with Lua Lua is probably the simplest, cleanest programming language I know. (And I know a few.) Lua's simplicity is also its biggest weakness: being a small, clean language by design, it doesn't have a lot of stuff built into it that you'd expect to find when coming from an industrial-grade language like Java, or a ...

I'm not sure about reference code; this is relatively new, and mostly what I can find are papers, not implementations with open code. A key paper is Fourier Slice Photography, by Ren Ng at Stanford University — now, not surprisingly, at Lytro. There's an abstract of the paper here, with a few nice pictures. This doesn't give you something that you can take ...

A lot of cameras can be controlled from a computer. Not sure if every camera out there can, but at least in my experience, every camera I used did. I'm sure about DSLRs: all the DSLR cameras from Nikon, Canon and Pentax have such features. I also know for sure that Canon DSLRs are sold with EOS Utility, that allows you to control the camera from your ...

I don't know Lightroom (yet - have it but haven't installed it yet), but depending on the complexity of what you're trying to do, you might want to look at a system wide keyboard macro/automation tool like AutoHotKey. It lets you record or program any sequence of keystrokes that you can figure out and then, when you press a hot key, it plays them back into ...

No, if it isn't detected as being attached, then there wouldn't be any way to communicate with it since it is effectively not plugged in.

If I understand you right you have your camera on your phone and you're composing the picture and when something bright enters the screen the lighting 'appears' to change (probably the whole screen gets darker). The camera will adjust what it thinks the shutter/aperture/iso should be to get the "proper" lighting. How does it know what the proper lighting ...

I would look at DSLR Remote Pro. As described on the features page: DSLR Remote Pro for Windows also includes a DLL and a sample program (complete with C++ source code) which allows other applications to release the camera's shutter and adjust the shutter speed and aperture. The software supports most Canon DSLR cameras, the 5D Mk II that you ...

You should apply the LUT to each channel. If you are really interested in image processing theory, then you should start a new question asking for book recommendations on the subject, if it hasn't already been asked.

I don't have access to Canon's SDK to know what's possible or not, but thought I'd point out you can also use libgphoto to interact with a tethered camera. It allows you to read and write a variety of camera settings. On the 1100D this includes ISO, aperture and shutter speed (and much more) so should be enough. You can even script this using Gphoto2 (which ...

I have just written a focus-bracketing script for closeup lenses, including the Raynox 250. Here is a link to my article, which contains documentation of the script as well as the script itself: http://www.dpreview.com/articles/9780512447/focus-bracketing-scripts-for-macro-setting-and-for-closeup-lenses Here is another link to some outdoor stacked images ...
