Thanks Gary, I had a read of those articles and found them quite challenging to fully comprehend, but very interesting none the less.:thumbsup:

Is that anything like the original Lytro was capable of doing?
Pardon my ignorance in asking, I haven't read the article and I really have to get to the shops so can't read it at the moment.
I have an original Lytro, it was amazing being able to alter the focus on the pc after taking the image.
