I'm not sure if it's been said, but changing your dpi will have absolutely no effect on file size. Don't even look at it. It's only for printing. _________________ brush your hair and comb your teeth

? Hmmmm....kinda right. Depends on if you have "resample image" checked or not. For photography, I always have it checked, so it resamples the image, and makes it larger or smaller in file size. As far as making it smaller or larger, there are a variety of filters that will make a file size larger, like unsharp mask for example (more noticable when saving as a jpeg). For work, our raw image is 300 dpi, and 47.6mb in size. When I crop it as a 4"x6" @ 300 dpi, the file size drops to about 9mb as a tiff, then when I save it as a jpeg, still 300 dpi, @ 9 (on the "save as" jpeg sliding scale thingy), it's between 280 and 310k in size. If I apply unsharp mask and try to save it at the same size jpeg (9), it jumps up to usually 380 to 450k in size.

For web-bound work, best to ignore ppi and just look at pixel dimensions.
(and let’s keep the terminology consistent: use “ppi” when describing pixel size in an electronic image and “dpi” in relation to ink dot size of printed images. You can have many ink dots per pixel.)
I forgot to mention "resample image" If it's unchecked, it won't effect file size, if it is it will. _________________ brush your hair and comb your teeth

My bad. I know what I meant to say It's just that I deal with printing photos and using "dpi this" and "dpi that" every day, so it's become rather habitual... _________________ All gave some, some gave all.....Lest we forget that war produces veterans, wounded both mentally and physically, and it is our job to help them now, as they have already helped us all in ways we will never know, and in ways that we take for granted every day.
