I know a photographer that is dealing with this. One comment suggested JPEGs were part of the problem. Should raw formats be used?

One comment suggested JPEGs were part of the problem. Should raw formats be used? A photographer should always use raw formats for /other/ reasons, however the fact of the matter is: corrupted data is gone. Sure lost bits on a compressed format can cause more havoc than lost bits on a raw, but the data is still gone... Resilient file systems that have checksums for data (such as ZFS) are the solution to the problem, anything else is just going to limit the damage.

=============================================================== From: William Roush ------------------------------------------------------ Also I should note the "raw" formats really depend on what the actual data storage structure is (can vary by proprietary storage format the vendor uses), because corrupting a few blocks in those can still ruin the entire image.

=============================================================== From: Billy ------------------------------------------------------ I don't really know. My purpose in saving my amateur photography is to capture as much data as po= ssible for as long as financially possible. Thus, I store in raw format for my camera. $$$ software can extract the data= better than free software. It's true. However, when I'm making more than I s= pend in time/equip, then I'll start thinking in those terms. For now, it's ZFS and amazon S3 as off site back up. There have been a few times where my lighting hasn't been perfect and the ra= w format let me get a good pic out of it after some post processing. Yet, th= ere have been times that I think the JPEG format produced a similar or super= ior pic with exponentially less time only part. And that means something int= o world.
