Selecting scanning parameters

The scanning parameters are of course important for the quality of the new digital "original". Below are some examples of the result of changing the parameters.

Resolution

This is the most obvious parameter. Up to a certain level the principle of "the more pixels the better" is valid.

Resolution xxx x xxx pixels Resolution xxx x xxx pixels

Hans uses: Highest possible optical resolution which means 4800 dpi.

Bit depth, dynamic range

xxxxx.

xxxx xxx

Hans uses: XX bits.

Dust and scratch removal

Many scanners have the possibility to remove dust and scratches.

Hans uses: Active dust and scratch removal based on ICE, normal. This means that the digitized image is not exactly as the negative. Software based dust and scratch removal must not be used.

Color model

sRGB Other

Hans uses: Every image is manually handled to obain, as far as Hans know, the correct colors.

File format

What is the best file format for the digitized images; tiff, jpeg, jpeg200, png or raw?

Hans uses: jpeg with high quality which means jpg-files of size between 3-20 MB depending on image details. A "normal" jpg-file size for a digitzied image is about 10 MB.
