I had some slides printed out as 4x6 prints. Now I want to scan them onto my computer, edit a little bit, then save them to be printed out as 5x7 size so I can mount them.

Provided you can get a good resolution from the scan, I would always use the highest resolution possible when it comes to editing and printing.

1) If I scan at say 1200 DPI...I could always resize the scans to 5x7 format. My problem is what pixel width and height would equal 5 x 7 when I resize?

If you want to print at 5x7 i would see what the photo looks like at that size and 8x10 first. I would try to optimise it at 8x10 so when printing at the 5x7 it will look better.

2) If I edit and make an color image sepia toned or other enhancements to it..how well does that print out after i save in jpeg mode? i want to print it out at the local photo shop or upload to MPIX and have them printed.

Trial and error. I usualy use jpeg. Do the local printing first before you spend money on the mpix and you dont like them.

Thanks for any help. I realize printing size for 5 x 7 is different than scan pixel size..but what final format should i save the image as...?

For printing i use jpeg. I would scan at the highest resolution you can, it will take more time but for editing and printing it will be worth it.

The other thing i would suggest is if you still have the original photo you got the slide from, i would take that down and have it put on a CD or floppy to do all this. Using the original will give you way better results than the slide. If you can get a decent image from the slide i suppose you can have the slide transfered to a floppy or CD also. (never worked with slides before)  Good Luck, i hope this helped.

Scanning the slides would be best if you can get your hands on a film scanner or transparancy adapter for a flatbed.

Output resolution will depend on the equipment used to print (i.e. Fuji Frontier, Fujitsu, etc..), usually 300 to 400 dpi.

Save as JPG on maximum quality if you must. I use TIF.
