So please send proposals. I did sit down and make a long list of things that I thought where missing from the SANE API for negative scanning and posted it to this list. I am not sufficiently familiar with the SANE API to be qualified to make good proposals on how it should be extended, and it would take significant amounts of my time that I don't have to do so. It seems to me a far superior solution for those that know what is missing from the standard to point out what is missing and for those that have intimate knowledge of the standard to add those features in the way that best fits in with the standard.

I sat down with the standard and scoured it for features that appeared to be missing but would be considered essential for proper negative/film scanning. I then wrote a long email explaining how all of these features work and posted it to the list. This was a couple of evenings work. To then expect me to become sufficiently familiar with the API to make good proposals of how to implement this features is in my opinion asking to much. It is hard enough to propose good API's even when you understand everything fully, but to skillfully extend an existing standard is in my opinion best done by those intimately familiar with it. > I can't talk about that specific scanner, but with my Mustek BearPaw > flatbed scanner I also get too much noise with dark slides or > negatives.

I messed around with scanning negatives on various flatbeds. The results where never very satisfactory which is why I have proper film scanner these days. JAB. -- Jonathan A.
