Focus on this. Or this.

· 497 words · 3 minute read

How many photos have you taken that are out of focus? The answer will be something between “all of them” and “some”.

If you have a small child rushing around, or are trying to focus in on individual people moving down the street; then your failure rate will be very high.

If only there was a camera where you could just snap away and then fix the focus later.

Take the shot below. It’s focused on the girl in the foreground. I wonder what the girl in the red dress looks like? Click on her. Now you know. Click anywhere and that point will come in focus (unless you are using a tablet or IE6).

It’s pretty extraordinary and it’s not a trick. It uses light field technology and if I knew how that worked I wouldn’t be sat in Pattaya writing a blog. But those that do know have developed a camera that uses it which will be on the market soon. I can imagine massive consumer interest, if it is cheap enough, with Facebook and the like being awash with snaps you can play “let’s focus here” with.

Have a play with more photos here, and be amazed.

Agree it’s all very clever…………. but why not just show all the frame in focus, as if depth of field was greater? Or am I missing some artistic principle?

Apparently you will be able to have everything in focus; or a selected depth of field; and 3D.

In the early ’90s when Photoshop was launched this “trick” was rife. Shoot full DOF of 4 girls. Apply diffuse mask layer to each. Click on any girl (layer) to remove the mask and presto we have a sharp area. Surely not!

It isn’t working - and I’m using Firefox 5. What am I doing wrong?

FUMF - Have yiou clicked on the arrow in the bottom R H corner and then clicked on ‘click to refocus’ ?

Duhhhh. Thanks Wally. Yeah - I’m a right one :)

In case my last comment was too cryptic - yes I hadn’t clicked on the arrow in the bottom R H corner.

Surely not indeed. You don’t attract $50 million in venture capital based on a Photoshop trick. It’s light field technology, which has been around for years, shrunk into a consumer size camera.

Focus bracketing?

There is no focusing. Read this: http://www.lytro.com/science_inside On the last page there is a link to download the thesis written by the CEO which explains how it works in more detail. This is not some trick using existing camera physics; it’s something new.

And if you have some 3D glasses, you can see that you can also generate 3D images from the data.
