Someone just asked me for the DPI of some images I sent them for film use. Where or how can I find that number(in PS?)

you can open on ps it and go to (i guess, no ps here at work)
edit > image size
u can check the resolution (DPI) and the size (pixels)

edit: by film, you mean, VIDEO?
72 dpi (monitor resolution) should be fine!

For printing, i wouldn't go lower than 200, but at least 300 is preferred.
And the DPI doesn't matter squat until you're printing the images.

EDIT: This should clear things up a bit: //en.wikipedia.org/wiki/Dpi

It's for a documentary short. I honestly don't know whether it's film or video. Not for print.

I was asked how many DPI the images were and I gave him the pixel dimensions. Maybe it doesn't matter that much.

DPI = number of pixels / inches you want.

3000 pixels/ 300 inches = 10 DPI for example (pretty bad quality ;-) )

Following the same idea, a 1024x768 image, on 300dpi would result on an image with 3.41"X2.56.

For video or film, I'd say go with 72 dpi.
Make it 1024x768, 1280*960 (like a wallpaper) and hand him this file, that should do!

That's all I can do...is to hand him the files. He asked me how many DPI and I drew a blank. I told him that depending on the crop they start at around 3000x2000 pixels and go slightly down from there. The samples I sent were at 640x? like DPC files.

Either he can use the work I've done or not. Maybe in the future I can shoot in RAW to help increase the file size and buy good interpolating software.

The thing is, the files itself do not have ONE final DPI setting. For example, the very same 1024x768, printed on 300dpi, measure 3.41333"...X2.56".
This very same image, at 150dpi can be printed at 6.82666"...X5.12".
It'll matter only for the final printed media.
That's why DPCprints take files with 150dpi, for the larger printed versions. Cz its acceptable quality, for larger media.

Well, if I have said anything wrong here, plz let me know!
