I have questions about sizing in PS CS2 and also about getting photos printed. If I wanted to print a picture as a 5x5 (maybe for a framed tryptich) would I save it in PS as a 5x5 and then print it as a 5x7 and trim the paper?

Also, when I crop an image, it obviously isnt going to be shaped as a standard print size (4x6, 5x7, etc.). What do I do about this? If I change to size of the image to a standard print size, it will most likely warp the correct look of the image.

Any other tips, tricks, or good tutorials you know if about this topic would be much appreciated!!

Your sensor is 3000x2000 pixels. This is a 3:2 ratio. (P&S cameras or other dSLR sensors might have different ratios)

So, the print sizes you need to choose to avoid cropping are any of the 3:2 ratios (think 1.5 times the shortest side)

6" x 4"
7½" x 5"
9" x 6"
etc.

eta: If you try to keep your crops to the same ratio as your sensor you can print to conventional print sizes like these listed above. If you stretch it too much it will look distorted, as you pointed out.

For your 5x5, add blank canvas to it so that it is 5x7 and print that, then trim that off. Usually, if your print doesn't match the exact aspect ratio of the paper size, the printer will "zoom and trim" your image, cropping off part of it you probably want.

I always add some border/canvass padding when they don't match up exactly -- that way I can crop for composition and not for print size. You can always trim or mat the photos later if you don't want a visible border.

I don't have the link where I am now, but if you go to Dry Creek Photo and look at their page on how to use printer profiles, there's a table at the bottom showing exactly how many pixels you should have for various print sizes on some different printers. They note that the printer will often scale up your image and lose a bit right at the edges, so you have to account for that too.

So 7½" x 5" & 9" x 6" are standard print sizes? I'm just not familiar with them.

nevermind about the 9x6, I just realized that I know it by 6x9.

I use www.photobox.co.uk for printing, and they have a selection of 3:2 ratio print sizes. I use 7½" x 5" a lot.

What do you do about picture frames? Do they come in that size?

I'm not sure about frames. I've only ever ordered prints or things like calendars or photobooks.
