General Q&A on all types of photography (including video).

I am not a video expert, but I am sometimes surprised to see interlaced footage in professionally-produced videos shot with high-end cameras. This often gives "combing" artifacts to videos (Youtube...
What's this pose called? Let's not call it crossing your palms! Anyways, in portraits, the subject usually never shows hands. Then why clinch your hands, then center them in the center of the port...
I've read many explanations, but either they all are too abstruse or they gainsay each other. Why Dots Per Inch Isn't Pixels Per Inch A dot refers to ink density, effectively; a pixel refers to...
I have a GoPro 9 and it has the option to wake at a specific time and take a photo/video/timelapse. However, some of the timelapses use 90% of a full battery (official GoPro model) and in the stand...
I take a picture on my phone, view that picture on my computer, then screenshot that picture. Then that screenshot's file size can ≥ original picture's file size! How? Why? This feels illogical! I...
I have a Canon EOS 2000d, and am a total noob to photography. I basically all my life just used cams doing everything automatically (and being unhappy with wrong focus or bad color settings etc ;))...
I'm looking to attempt some artistic shots of a competition rifle shooter doing what they do best. My first thought was to attempt to capture something like a perfect golf shot, where you capture t...
I am not sure if this question is off-topic here or not (probably it is and if so please help me find the correct network site, if there is one) What was the first film with subtitles in the histo...
For sharpening photos out of a DSLR, where the final result will be at a lower size compared to the DSLR's output (for example, for publishing on the web), is it better to: apply (possibly slightl...
I never cleaned any lens from any smartphone camera and I hope that future smartphones won't require me to do that. I don't know almost anything about camera technology; I am not familiar with the...
Shadows move faster at the beginning and end of the day, and so a time-lapse with an interval that would show movement then probably won't at the middle of the day. What should the interval be for...
The issue: I will be using photoshop to create a photo of my friends Mike and Jim with their favorite drinks sitting at the same table. Jim is visiting this week and has an expensive bottle of sc...
There was some years ago announcements of new developments in cameras that were able to record the intensity and time lag of light that they detected to be able to view the range topology and refle...
I am going to print some lithophanes on my Ender 3, which has a moving bed. How should I align the object for the best quality?
I have been 3D printing some lithophanes, and so far I have been doing so with pictures that I took a while ago. If I were to go take pictures with the purpose of turning them into lithophanes, ar...
Given that the difference between black and white on a 3d printed lithophane is the width of the plastic, the greater the difference between the max and the min-width the more variation of grey the...
For a lot of time-lapses of 3d printers like this one the picture is taken when the hot end is either out of the picture or in the same place so that the focus is on the object being built, not the...
After reeling a fish in, sometimes I want to take a picture before I let it go. So I unhook the fish and hold it in one hand while I take the picture with my other. I am usually in a hurry to get t...
I recently bought a large projector at auction and it came with a 133mm diameter lens but no caps or covers. Where do I find lens covers for such a large lens? The universal lens covers I've seen d...
When I take pictures of (lit) candles in otherwise-darkened rooms, the flames always come out nondescript (blurry?) as in the following example: I took this picture with a hand-held cell phone. T...
I'm trying to take a photo of a white paper heart in UV light, to make the heart look like it's glowing. I expect that the heart is going to look, well, purple, rather than white. I'm taking this p...
I've recently acquired a set of mobile phone camera lenses - the sort that screw into a clip, and clip over the top of your phone's camera. These are the lenses: From left to right, they are (a)...
How are the modern instant camera technologies achieved? Is it pigment transfer, laser sensitized paper or what? Are they optical or digital technologies?
