Does anyone out there worry about future-proofing your RAW files? After experimenting with Lightroom for a few days, today I decided to trial Aperture. I'm trying hard to convince myself that Aperture suits me best (mainly for the $ saving) so I was really disappointed to find the raw files from my old Canon Powershot S45 are not supported in Aperture. I know I can always open them in another RAW converter and then import them (which is what I've done using GIMP/UFRAW) but it adds another level of hassle that I could do without. At the end of the day I'll probably still end up using Aperture, but it got me thinking about whether I should convert all my master images into a more future-proof format? Is there even such a thing? DNG? TIFF? Or do you think older converters will always be out there somewhere? It may at least be a good argument for routinely shooting RAW+JPG. Obviously all digital formats suffer from obsolescence at some point. You probably need a crystal ball to work out which will have the best longevity. The safest gamble? Probably some combination of open formats and popular formats. Philosophical and practical thoughts welcome.
