How are you going about making it a poster? Scanning it and then blowing it up? Taking it to a print shop? Please give more information.

It's already scanned, and I have a couple of touch ups to do in Photoshop. So I'll have to blow it up. Or maybe I can make the touch up and then take it to the print shop to enlarge it?

How are you planning to output the file? If you're going to take it to the print shop to print it, then I would strongly suggest you make it the size you want at the resolution you want in the computer file, then take the computer file to the print shop to have it printed. What you'll probably need to do is this:

If the poster is going to be 28x42, you should probably print it at 65 line screen, or even 50 if the print shop will do it.  Set your DPI to twice what the line screen is going to be, i.e. if it's 65, set DPI to 130. If it's 50, set DPI to 100. This means that you'll multiply the DPI by the dimensions (28 and 42, respectively) to get the size in pixels of the image file.

THIS WILL BE VERY LARGE!!!! You will proabably need to give it to your print shop on a Zip disk.

Once the file is the size you want it to be, you will probably want to run it through some image filters to get rid of the blockiness that will arise from increasing its size so much.

On the other hand, if you want it to be easier, just take your original photo and have it blown up directly...
