Embed ICC Profile

    I have a few hundred:( pics that I need to scan (old family photos).

    I'm going to use an Epson Scanner, a stylus SX515W.

    I've been reading up abit today on Resolutions, File Formats and that sorta thing as I really want to do this right first time.

    Most of the guides I've read say to just leave the dpi at 300, unless I'm enlarging them, I've no planes to enlarge but just incase I've jacked dpi up to 1200.

    I'm using .tif to save them as it doesn't use compression, space isin't an issue really.

    (1)What should I be using as a "Target Size"? I'm gonna put them on a SD card to display them in a photo viewer (something like this) but unless I pick 800x600 I end up with black borders on the pic in the viewer, anyone tips on this?

    (2)What I'm really stuck on is the ICC Profile, the scanner is set by default to include them, my basic understanding is the profile tells whatever is opening the pic how to display the colours...yes? So I should keep it?

    (3)Now if I scan the pics with the ICC, will they come back to bite me on the ass in a few years by stopping some program from displaying the pics?

    (4)Is their a way to strip ICC from a pic then just incase, an easy way?

    (5)Is their an easy way to convert a batch of .tif pics to jpegs so I can fit more on the SD card while keeping the lossless .tif?

    Any other tips?

    If you're only going to display them on a screen, then anything above 72dpi is a waste because that's all it will display anyway. Save the profile as sRGB for display and RGB for printing - again, an electronic display will only display as sRGB. Also if you ever want to print, then 300dpi is perfect.

    I would have thought you might as well record the images at 300dpi sothat their future proof.

    Personally I'd send them off to a professional crowd to have them scanned, if possible. We have decent scanner at work and even so it's not great, If you want the best quality consumer scanners aren't the best and you'd save yourself hours and hours of scanning.

    I think you should aim for the best quality scans and compress them later for an SD card if needed. Aiming for a limited SD now could mean making sacrifices.

    Basically, you want to have your target size and resolution set so that they're the print size you want when they're 300ppi (or thereabouts.. some printers print natively at 360ppi). So for 12x8s for example, 300ppi at 12x8, or 600ppi at 6x4 or 1200ppi at 3x2. I'm not sure if the scanner quality starts to suffer as you push the upper limits of resolution.

    ICC profile, safe bet is adobe rbg for the moment (still a good safe bet for the majority of printers on the market). Save as 16 bit tiffs (not 8) to retain maximum data.

    Irfanview or photoshop script processor will convert down to jpg as a batch job for you, but you lose a lot of latitude for post processing when you convert to an 8 bit file. Best to leave that step till you're ready to print if possible.

    Just to add, it's better to scan for print as per above, even if you don't plan on printing. At least you'll have the option and it saves you doing it twice :) you can always make them smaller, and browsers display adobe rgb no problem these days..

    Not at the kinds of resolutions you'd be scanning prints at. depending on how the it was done most modern scanners can comfortably out-resolve a print. I'd just scan the lot at 600dpi just to be sure to be sure, and save out (as above) as 16bit tiffs. I'd crop / rotate / dust spot on the tiffs but I wouldn't do any potentially destructive colour corrections or anything of the sort on them, for that I'd process them into JPGs for print and upload and mailing around the place and what not. That's my normal (negative) scanning workflow.
