New camera lets you focus photos after you shoot


edition.cnn.com
(CNN) -- An auto-focus camera? Not new. Not exciting.

A camera that lets you focus after you've already taken the photo? And lets you focus anywhere within the image you want? That's got people talking and, according to its creator, is the start of "a picture revolution."

Oh yeah -- it can also transfer a regular photo to 3-D.

Lytro, a company launched Tuesday by 31-year-old entrepreneur Ren Ng, promises that camera will be released soon.

"I am thrilled to finally draw back the curtain and introduce our new light field camera company, one that will forever change how everyone

This tech has actually been around for many years. I saw a demo of it online ages ago. Igt is called a pltenoptic camera.

It works by splitting light on a multiple focus array, recoding distance info with luminosity or something similar. I was wondering when these would hit the market.

Here is a link to a 2005 arrticle about this technology

www.dpreview.com...

follow the linkt to the examples, they are very cool.

I don't see this taking off as a mainstreem technology. It may be a consumer fad for a while. But there is not enough controll for the professional photographer due to the losses in other areas like exposure controll. It also reduced the effective megapixel count on your sensor as the pixels are collecting distance info as well as light, so there is a significant loss in resolution.

Very cool though!

Also info on this from Jackatmtn's thread on the 22nd if anyone is interested. www.abovetopsecret.com...

Being an amateur photographer, I'm salivating over this of course. Definitely cool. I'll bet it won't be long before the other major camera companies follow suit on this. But I still like my Canon DSLR. It does a great job for me.

I am not sure about this technology. I have been a keen amature photogrpaher for 20 years or so now. I think learning to use the camera to create the immage is part of the skill. Also, think about how muchpost processing would be required if you have to go home to refocus 300 pictures at the end of your holidays!!

Also, I think there would need to be a lot of controll over depth of feild, just pulling the focus about is only half the story.

Here is a very good technical description of how it works, for those techie geeks (like me) who like that sort of thing.

I have to agree with you there. But I do think this could have a place in the photographers toolbox in certain situations. Especially those who do photojournalism, sports, etc. I wonder what Ansel Adams would think about this technology?
