For instance, there is now a way for Adobe (and others) to remove lens distortion from the image.  Since this is a new function, it’s necessary to make a new version of the spec that details how to save and apply the instructions. One thing this enables is for cameras that don’t work well with the current DNG spec to now be supported. Check out Tom Hogarty’s blog to see the new camera support.

There are a couple of breakthroughs this drive offers.  First, some background, after the jump. Continue reading SSD Drives coming of age
