Image quality when scanned
After making a mistake of sending scanned prints in as jpg.I then read the large print to send them in as tif.But sadly,even though tif is a bit better, they still lose crispness,relative to the print I scan, when I drop from say about 1700 Pixels(long)as scanned to 750 Pixels(long),when I reduce to submit into the comp .I realise this may always be a problem,but what I ask is this, if one uses a digital camera,is this ever a problem? Also I could get a CD made as well, at time of processing....would this alleviate the problem in reducing the size.I am ready to take the best option,as I am finding this very frustrating.Joe.

When you reduce to 750 pixels in image width, are you maintaining a 72 pixels per inch resolution?
Also, you can choose a degree of JPEG compression, at least in the Elements/Photoshop imaging programs. For betterphoto, there's no need to compress any more than about a 10, as I think betterphoto's software may do a further compression.There's really nothing wrong with scanning a print. Scan at 300 ppi, do your edits (cropping, tonal adjustment, dust spotting, and THEN convert it to a JPEG (72 ppi, 750 pixels long). All this presupposes that you are using a good imaging program, Adobe Elements 2 being a great one for $79.

Sorry, Joe, almost forgot. You can sharpen the JPEG, bringing back some of the sharpness we lost in the conversion process. In Photoshop-based programs, it's under Filters/Sharpen/Unsharp Mask. The three Unsharp Mask settings for a JPEG should be about .86 as an Amount, a Radius of .6, and a threshold of 1 or 2. Experiment with these settings as a starting point until it looks sharp without being harsh.
