Image format for digital printing/enlarging?

[ander]

I want to have these three photos blown up to poster size so I can frame and hang them

1
2
3

What image format should I save them in before I bring them to my digital printing store? Anything else about size/resolution? Brightness/contrast? Color correction?

Thanks for the help.

something loss-less like tiff would be good, although I didn't look to see what format they're in now so it might now matter anyway

Doesn't matter at all, really, they're not going to get any moer detailed than they already are. If you take them someplace decent (a.k.a. NOT Kinko's) they'll make sure they're using the correct color mode.

EDIT: I thought these were digital, but if you have them on film, 300dpi at full size (meaning, if they're going to be 5x10 inches, the final resolution should be 5x300 = 1500 x 10x300 3000 so, 1500x3000) is standard, however many digital presses print much lower than that - as low as 120dpi, so you should call your printer and ask what he wants. TIFF is a standard lossless format, but a JPEG at maximum quality will be visually indistinguishable, and fit much more nicely on whatever digital medium you're using. If you're scanning them yourself, you might as well jsut save them in CMYK.

Phuket, Phuket, and Hua Hin all in Thailand. The other pictures I took in Asia weren't as impressive.

They're all digital taken w/ my Cannon S110.

I'll give TIFF a try. Thanks everyone.

If your digital camera already saved it in jpeg format, then it would not matter if you changed to an uncompressed format.
