File format Tiff uncompressed (16 bit if possible) JPEG2000 looks interesting but too few programs can use it. I would consider storing RAW but there is no guarantee that it will be readable in 10 years
raw is *guaranteed* to be readable for as long as C complilers are available, since dcraw.c is an easily available open source program. just burn the source code together with the images once. in fact, i think, this is the only reasonable archival format for digital camera images: it keeps all the information camera captures, but no more. consider 8 bit tiff: if your camera has 12 bit raw, instead of storing 12 bits per pixel, you'll store 24, but only 8 of them will have the real information, you store more data, and at the same time you lose some information! with 16 bit tiff the ration is 48/12, that is, raw gives 4x comression automagically (of course, i am talking to raw formats that store just the raw data, i.e. canon raw).
