Did just that. They look exactly the same in FCP. I know that PS used to handle DPI flat wrong when it came to video (v. 5.5 if memory serves) and it may still allow you to mess things up yourself by resizing photo components incorrectly but if your workflow is solid, there are no issues with dpi in PS going to FCP anymore.

And I remember exactly what you are talking about. I just haven't seen the issue since v5 of PS. (I'm running CS3 right now)

Actually, you need to use the descreen filters in your scanning software while capturing the image (experiment with the amount used), otherwise you'll find horrible moire patterns caused by the printed dots. You'll find it much easier than trying to remove the patterns in Photoshop. If at all possible, you'll be much better off scanning from originals.

And you have permission to use this pre-published material, of course?

The images I will be using are either from a magazine or original 4 x 6 pictures taken with a 35mm camera. I am also receiving some negatives.

I don't think my scanning software has any kind of "descreen filters", I will have to check.

YES I have permission! lol.

If your scanning 4x6 and want to zoom in FC, scan at 600dpi. If you don't have a descreen filter and you are having a moire problem in FC, you can try in PS to add a gaussian blur and then unsharp mask to sharpen it back up. Can't really give specifics as every pic is different, A lot of times I'l blow them up to double the size & then blur. sharpen & then resize down again, Works more often than not. On some occasions, I'll blow it up x2-x3 and then apply the dry brush filter, very large files with a dry brush applied, ends up looking like a picture, but the dry brush kinda scrambles the pixels & color just a bit.

I've just finished a project with thousands of 15 mp stills and my 2.93 quad handles it very well, even with 3-5 layers.
