Anyone with a reasonable understanding of mathematics and physics wouldn't have found this remotely impossible, just very complicated and difficult.

Did I say "impossible", Rob? I said if you asked somebody if it was possible they'd laugh you out of the room. Not "impossible", just not credibly possible.

Isn't "very complicated and difficult" basically the same thing as "virtually impossible" taking the contemporary level of technology into account?

Somebody want to sweep up all of these spilt hairs on the floor?

This is what happens when you don't use conditioner you know.

Maybe should go in its own thead but since the Lytro camera (allows you to focus after taking photos) was mentioned here earlier, I'd post Wired have reviewed it

http://www.wired.com/reviews/2012/02/lytro-camera/

can see for yourself how magic it is here:

It's quite cute changing the focus, but after a few plays it starts to get boring. I'm not entirely sure what the point of it is, outside a point and shoot camera aimed at people who are incapable of getting what they want in focus (or deciding beforehand).

Though the Wired article looks at it as a unique way of taking shots, like a polaroid camera, which is a point I guess.

And because of how it works, the physics of light are against it at every stage. It has to capture so much more data than a normal CCD/CMOS chip, which inevitably means the resolution and quality is going to suffer. It says it captures HD quality, so I guess 1920x1080 which is way behind what all but smartphones are doing.

The picture quality of the examples was also really poor, seemed much like my iPhone 4 (which is awful in comparison to any dedicated camera).

Horrible bokeh too, but if they can improve that and the image quality, it looks interesting to experiment with.

It's not about changing the focus, it's about depth of field. Being able to have things in focus from millimetres from the lens to kilometres. You take a picture of your kid's birthday party in available light. You can have everybody in focus as if you had the lens shut right down and blinding light flooding the place by selecting elements from each of the planes the camera has taken.

People who want to muck about with a very narrow type of technology to make art with it, like say a polaroid camera, that seems the only reason for it to me.

As a substitute for understanding proper exposure, aperture, focus and depth of field, it's never going to become the go-to kit for talented photographers. I'm not saying I am one of those, merely that in my dabblings I don't want someone else changing my images like that. I get angry enough when my mum says she cropped ones I printed out for her with scissors so they fitted in a frame.

Now I see it as giving you the ability to capture a moment with the same care you'd take a carefully composed photo, rather than curing the ills of the most ham-fisted point-and-shootery.  Even the most expert photographer has to make compromises when composing a shot.  Where to focus, what to allow to drift out of focus, the compromise of depth of field over exposure.  I see kit like the Lytro giving talented photographers an extra tool in their repertoire rather than being a camera that can turn Joe Public into David Bailey.

The Lytro is getting underwhelmed reviews (including Monday's Gadget Show) mainly because of the high price point of $499 for the 16Gb memory camera, and the poor finished resolution of 1080x1080 pixels (roughly 1.2 megapixels).

That's right.  1.2 megapixels.

I think I'll stick with getting the focus right to start with.
