Hey guys :-) i wanted to add pictures to APS Czech extraliga sets (1994-1995 to 1997-1998) i scanned all of them but it seem they are pretty big (i scanned them at 1200dpi) so I want to ask. What is ideal DPI for cards scan, so they dont extend 1MB size? I really want to do that right...so Im finding best compromise between size/quality.

300dpi is the most you would need and this is what I usually scan at. Occasionally a few here and there come out to be more than 1MB.  200dpi will always work but I like  mine at 300dpi.

Thank you very much :-)

I originally used 200dpi, but ever since the zoom feature was added I've been using 300dpi to get that extra detail.

Thx guys :-) one more question. Do you have some experience with scanning 9 cards through foil and then crop them? Seems to be much quicker.

I use a program called Ransen Scan (ransen.com) that automatically picks out the individual cards when I scan 9 at a time.  It relies on contrast between the border of the item you are scanning and the background of the scanner lid to tell where the edges are.  Sometimes it does a great job, but most of the time you still need to do a bit of trimming to get excess white or black off the image.  Since the scanner lid is white, of I'm scanning cards with light borders, I just leave the scanner lid up, so it gives a dark background for contrast.

There used to be a great program called Instant Photo Scanner, that did a much better job, by a German company, but they abandoned the software, and now you can't even buy it.  Some scanners come with software that can already pick out separate items on the scanner bed, but those seem to be few and far between.

I typicall scan everything at 600dpi, and then resize down to 1000 pixels on the longest side before posting.  Oh, I use ACDSee for all of the rotating, cropping, resizing and whatnot.

Resize the images down to 600x840 and the zoom feature works, the quality will be good and it'll be under the 1M limit

I use AcDSee as well and am very impressed with it for all editing.  300dpi for all.  

I originally scanned everything at 300dpi, but still ran into issues with moire patterns on cards with certain designs.  I found all of that went away at 600dpi.  Now it is just habit, even when it isn't necessary.

I'm also in the habit of scanning at 600 dpi and then resize the long side down to 1000px. I've been using Photoscape X for straightening, cropping, resizing and color adjustments but I recently learned how to do those things with multiple images at once by using batch editing in Photoscape X.
