Hobbyist photographer back in the '70s and '80s. Took my first photo when I was five years old, got an SLR when I was ten. (Film, all manual, handheld light meter, we had a darkroom in the basement.)
Shelved the hobby for a couple of decades. Returned recently, this time with digital equipment.

Jack of many trades (and master of none), but I have a professional background in software development.

comment Is it possible to get an interval precise up to 2 decimal places using a (software) intervalometer?
Triggertrap can probably do it. You'll need an Android or iOS device and a trigger dongle for the camera, about $40. Use the timelapse function, it can be set in intervals of 1/100th of a second. This is a comment rather than a reply since I don't know whether you'll get 10ms accuracy in practice, or whether the LP player RPM will stay that accurate over 12 hours. For accuracy I'd go with Russell's suggestion.

comment How to change aperture in manual mode on an entry-level Nikon SLR?
One more thing: Turn off Auto ISO, or the camera will compensate by adjusting the ISO. (Assuming the D3200 works similar to my D5100.) This doesn't affect the aperture, but it does affect the exposure, the brightness you see in the picture.

comment Relevance of absolute light power in studio object photography?
I meant subject rather than room: E.g 50 W bulbs in the softbox should give the same contrast as long as you can reduce the ambient light to 3-4 stops below the light from the softbox. In daytime that might require a windowless room or heavy curtains, but it's doable.

comment Relevance of absolute light power in studio object photography?
Good point. Although if you use a 50 W (equivalent) light bulb to light up the room, I assume that the ambient light is even lower. So perhaps the absolute light level doesn't matter, but the relative light level certainly does.

comment Relevance of absolute light power in studio object photography?
@zsz85 I guess it's because most studios also shoot people, and if you're at f/16 (for depth of field) and ISO 100 (for low noise), few living things can hold perfectly still for that long. In short, they want to be able to freeze motion.

comment How useful is silica gel for protecting SLR cameras against condensation from changes in temperature?
On battery: batteryuniversity says "Batteries that would provide 100 percent capacity at 27°C (80°F) will typically deliver only 50 percent at –18°C (0°F)" and "at –20°C (–4°F) most nickel-, lead- and lithium-based batteries stop functioning". 50% loss at -18°C matches well with my experience.

comment Are there digital cameras with a RGBW sensor?
I couldn't find any cameras, but there are two 2007 patents on RGBW sensors. Maybe Fujifilm just wanted to avoid an existing patent? Interesting sensor, but writing the de-"Bayering" algorithm looks rather challenging...

comment What cellphone is the best for photographs?
The Nokia 1020 is the best that there is for now. See Smartphones vs DSLRs vs film. But for "zoom in very far while keeping the high definiton" - sorry, then you'll need something more than a phone.

comment How to take a “bird's eye view” of a product at home?
So you want to mount the camera higher up than most tripods will go, with some flexibility for adjustments? A C-stand, a super clamp and a tripod head should do it. Plus a sandbag for the base of the stand, so it doesn't tip over when you extend the arm. See discussion here.

comment Can I make a Nikon AF Nikkor 50mm 1:1.4D auto focus on a Nikon D3100?
For accurate manual focus, use the live view zoom function.

comment Is optical image stabilization a necessary feature for any lens?
+1 Bird-watching: WANT for birds sitting still. DON'T CARE for birds in flight, since you'll be at 1/250 or higher anyway to freeze the bird, and the VR/OS can interfere with the panning required to follow the flight.
