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...
Instead of "stripping" EXIF data, think of it as making a copy that doesn't include it. My various image manipulation programs do that by default when writing JPG output files. This may have chan...
I removed the answer because it didn't actually address the question. The newer answer had nothing to do with the decision to remove the earlier answer, except for the fact that it bumped the ques...
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'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 just saw this ad on another Codidact: It gave me a good chuckle, but maybe isn't the clearest messaging for newcomers. My understanding is that moderators can exclude certain categories of que...
