Scanning TIps - General
For images intended for e-mail attachments, save them in .jpg format, with the high quality (little compression) setting.
For images intended to be sent via CD or DVD, save them in .tif format, which does not compress the image data.
I prefer to work with .tif format and I strongly suggest it to you. Tiff files are lossless and do not attempt to compress the file size by "fudging" the color information in the image data. Why reduce or limit the obtainable quality of the restored images right at the start by not making the scan as good as possible?
Begin by wiping the glass of the scanner with a non-abrasive wipe and some glass cleaner like Windex. Make sure the glass is dry before placing the photo down. If you have a can of compressed air, you may also spray the glass and (carefully) the photo itself to remove any extra dust or debris. Also, make sure the photo rests against one side of the scanner so that it remains straight. Preview the photo before scanning it. Please do not use any of the sharpening, de-screening, dust and scratch removal, or color correction functions of your scanner. Make sure they are all turned off before you start your scan.
The resolution, or dots-per-inch (dpi) that you should scan your photos is based upon their size. For Photos 2x3 in. or smaller — Scan at 600 dpi. For Photos 2x3 to 5x7 in. — Scan at 400 dpi. For Photos 5x7 and larger — Scan at 300 dpi.
The size of my working files is usually range between 5 MB to, sometimes, well over 100 MB. This allows successful printing of images with dimensions up to twice the size of the originals. Such enlargements are not feasible from .jpg images due to the image compression.
