At Max 2011, Adobe demonstrated a new Photoshop feature which is likely to wow and simultaneously strike fear into photographers the world over. The technology that they are working on enables the 'deblurring' of any image using a complex calculation.
This can probably explain it better than I can, "Adobe's approach is interesting - and quite compute-intensive. The analysis of the picture tries to trace the path a picture was blurred - it basically attempts to recreate your hand movement during the time a picture was taken, based on the blurring in the picture. Depending on the size of the picture, this process can consume some time, but the effect that Adobe presented on stage was breathtaking. In one example, the software even revealed a blurred phone number in a picture."
My first thought with this revelation was - "We're screwed."
After giving it a good bit of thought however, I don't think that it will negatively affect photographers very much, if at all. You wouldn't be wrong to think that anyone with a camera could point and shoot at anything and use features like this to fix the image up later on, but the resulting image wouldn't necessarily be any good. To get a good photograph you need to know how to take a good photograph, and that will never change... hopefully.
Better quality example of effect can be found here, where I found the info.
