Not particularly interesting... Does too much for the photographer. Why not just create a camera that generates images for you without you having to go out and take them while you're at it? Oh wait...

This is game changing IMO. No more out of focus or wrong focus point shots. Get the perfect shot in every shot. Will be very enteresting how well this works in the real world but it sounds amazing right now. I see wedding/sport photographers loving it. Portraits where you have more time to adjust maybe not so much but still just the option to change the focus to anything is just crazy. It's the biggest camera break through since digital IMO.

Anyone care to try and explain how this works if you're shooting sports at say, 1/4000 @ f/2.8?

There was another example linked which showed a mother behind a baby and while you could float the plane of focus to a significant degree, you could not get the mother's face as sharp as the baby's face at all.

I can't see this working without max depth of field and therefore, slow-ish shutter speeds.

Happens frequently around here. Newbies are sure they've stumbled across something that nobody else has seen and rush to "scoop" everyone else.

couldn't just set a very small aperture and do this in post?

The main problem I saw is that you don't really have that much control. It almost felt like there were click zones, rather than complete control. A subtle change didn't move the focus for me. Who knows, maybe I just don't know how to use a mouse and click with it... :p

Playing on their website...if that is 100% representative of what the camera can do, WOW, that pretty much revolutionizes photography as we know it. Right now it's vaporware though. It looks to me that just as our cameras take pictures in RAW with +- EV, this does the same for focus data by recording data in a 3D matrix ("light field") instead of just a 2D plane.

Very, very cool. The first DSLR manufacturer that either licenses this tech or creates their own version will have a compelling product right away.

It won't work for sports, the inventor says that it doesn't give good results with moving subjects "moving objects will cause sloppy source imagery and difficult to correct blurring in your final lenticular image".

I also agree with your comment about max depth of field. The lenticular image is, effectively, several images recorded at the same time, with different focus. So, the corrections are stepped and not infinitely variable. This will work ok on a point and shoot, with a small sensor and deep DoF, so that the DoF of adjacent steps will overlap, but on a DSLR with it's much shallower DoF? I can't see there being enough variants stored to enable the precise positioning of the focus that we require, particularly when shooting wide open for subject separation. I mean, look at all the people who worry about half an inch of front or back focusing.

Probably a nice USP for a compact, but not going to impact DSLRs for a long time to come.

Hrmmm...I don't have a lot of OOF shots lying around. That's what the AF sensor on the camera is for. This is an attempt to turn photography into some spray-and-pray foolishness, isn't it?

That assumes that all the camera is doing is focus stacking with a single lens the way it is done today. From what I understand, that is not how this is works and I'm thinking that this would work in a SLR as well after reading up a bit (external link).

This is a plenoptic camera (external link) and it not only is capable of recording the intensity of the light but via an array of micro lenses over the sensor, the direction as well. The image is then generated via some heavy duty processing. So in essence an infinite number in interim steps are generated.

The more I'm reading, the more I wish that they had gone the license route. This could really be interesting.


Not sure why, but call me JJ.

Sounds interesting, but it wont be long before we just send the camera out for a walk and sit by the fire with a beer or two. :lol:

There was a comment in one of the articles I read that said the resolution may not be so high (yet). I know this is not the fate of most digital photos, but I wonder how they will print. And do any serious photographers want people messing with their carefully thought out compositions? I don't see it going mainstream for a few years, but it certainly is interesting. By the way, the Lytro office is just a mile away from where I work - I might have to go check it out!
