comment Is there any library other than gphoto2 to use remote capture in Canon G10?
Are you asking for faster shutter speed, less shutter lag or higher frame rate? What are you current results? Regarding frame rate, continuous shooting with G10 is limited at 0.6 fps with continuous AF and RAW, 1.4fps without; no software would speed up past that.

comment How can I extract still frames from an MPEG video with Photoshop?
Before voting to close this question as a purely video-related question, please consider that extracting video frames is sometimes suggested as a workaround for some still photography problems, e.g. long shutter delay, short maximum exposure time or low frame rate.

comment What is the purpose of a dual LED flash?
@androiddeveloper Yes, its LEDs were of different color, as explained in the answer.

comment What is the purpose of a dual LED flash?
@androiddeveloper I'm afraid that would be hard to determine. It was rarely hyped as a feature before iPhone 5s. For example, my Sony-Ericsson K750 (a feature phone from 2005) had dual LED, but specifications usually mention only LED flash.

comment Why does exposure vary subtly between P, A and S modes, when the flash is on?
Slow sync affects timing of the flash, not metering (i.e. "when", not "how much").

comment Why does exposure vary subtly between P, A and S modes, when the flash is on?
Canon DSLRs meter flash to be a main light in P mode and fill light in Av/Tv mode. Perhaps Sony makes a similar distinction?

comment How to photograph low light indoor sport?
Underexposing to keep ISO lower will eventually result in more noise after post-processing correction than using correct ISO would, see Is it better to shoot with a higher ISO, or use lower ISO and raise the exposure in post-processing?

comment Why is the focus indicator light always on in single point focus mode on my D7000?
@AnedaSmith Yes. With thin depth of field, using focus point closest to subject final framing will generally improve focus accuracy. In certain situations, closest cross-type focus point may have an advantage.

comment What algorithm can I use to simulate bokeh?
Perhaps this would help: What's the difference between Bokeh and Gaussian Blur?

comment Why does my Canon DSLR stop recording video automatically?
My 2 cents: it's on topic because if the problem really is caused by slow SD write, it would likely also affect burst mode shooting limits

comment What exactly is flash sync speed, and should it be a factor in a buying decision?
Note that when action is so fast that faster than sync speed shutter is needed to freeze it, there will be rolling shutter artifacts visible because capture time of edges of the frame is still sync speed apart.

comment What's the difference between CCD and CMOS image sensors?
@smigol That is indeed how fast sync works, but it will be less efficient regarding flash to ambient light ratio.

comment Is analog gain really actually power-of-two only?
I doubt it's nitpicking when shooting JPEG, where the idea might be to avoid need for post-processing as much as possible, and there's much less leeway in dynamic range.

comment Why is there a mechanical shutter in a digital camera?
@ybungalobill Thanks for pointing out, edited to clarify this. It appears the technology is implemented in high-end cameras, but most people just wouldn't consider million-dollar systems (or even $30k systems) a viable option for photography :)

comment Is it safe to zoom while taking a photo for the effect?
What about AF mechanism, can it be left engaged? Simpler lenses don't allow AF override, and zooming affects focus on varifocal lenses. E.g. a Canon zooms manual warns to not touch rotating parts while AF is active, but it's hard to align zooming exactly with shutter.

comment Marathon & Sports Event Photographers: Are they freelance or agency/company-related?
A photographer has quoted the rate of $.17/photo in 2013.

comment Wide angle or ultra-wide (fisheye) lens for interior and exterior architecture shots?
For your listed usage, fish-eye really isn't an option, unless you really like dramatic and fun bent houses.

comment Why is the image size different in portrait and landscape mode?
Is portrait/landscape mode the only difference? If you're using another lens as well, I'd imagine lens correction having a role here.

comment How useful is the top LCD screen on a DSLR?
And there are plenty of models where LCD cannot be tilted even without water protection cover.

comment What are some other terms for a 3/4 shot?
The Wikipedia article has a disclaimer regarding missing references, so it could be just one editor's opinion. There is a historical reason why the term developed in cinematic context, but as a notion of composition I don't see why these terms couldn't be used in photography (especially 3/4).
