Few products make everyone here at Engadget quite as giddy with excitement as Lytro's light-field camera. Given how regularly we need to photograph things, we were desperate to know if this was going to revolutionize the way we snapped pictures. It had more than a few things going for it, innovative product design, great engineering, it was fast, responsive and had a great UI. However, the pictures themselves were of a low resolution, and the depth-of-field trickery only works with extreme close-up-and-background shots where you can mess around with your bokkeh. As nice as it is in theory (and practice, on a well-lit day), it's certainly not going to replace your DSLR any time soon -- but given that the company's presumably working on version 2.0 of the device, what would you suggest they tweak?
