I hope this is on topic. If not, I apologize. I scan old photos -- part of a conservation program. I scan at 600 dpi and save as .bmp. As you can imagine, the files are huge - - up to 30 Meg -- but since I'm doing this for the future, I want as much info as I can gather. They do print at near perfect reproduction and future printers will do an even better job. But I'd also like to have some of these photos on my computer to show on my monitor, where anything over 100 dpi is a waste. I can convert the .bmp to .jpg and I have a wonderful program (JPEG Wizard - and it's free!!) to bring the .jpg down in size without losing quality. But the file is still about 250 K. If I scan the photo at 100 dpi I can get the file down to around 10 K. So my question is: is there any way to convert a 600 dpi file to a 100 dpi file? Or am I condemned to scanning every photo twice, once at 600 dpi and once at 100 dpi?
I'm sure there's more than one way to do it, but in PhotoShop, I can go into 'Edit' and 'Image Size'... there, I can change both the physical dimensions of the file as well as the dpi. Look for something in 'Edit' or 'Image'... not familiar with JPEG Wizard, though. Sorry. You might also look into saving in some format other than BMP... it's always been my understanding that that format is the worst of the lot for archiving.

Hello I agree with Jen. In my opinion the Tiff format would be much better if you going to use that much space.
