Topic tags/keywords: light field camera

This was new to me. A Light Field Camera.

I think this is pretty cool. A completely different type of camera that gathers all the light from different directions in a scene and saves it. Then later you can determine what you want in focus, what colors, contrast, etc. There is actually one coming on the market. It uses a completely different type of sensor, optics, and software than a regular camera.

So to get an idea, see the link. Select a picture from their list. Now click on different parts of the picture to get them in focus. Some of them are pretty amazing.

They say that they have software that will also bring everything in focus, if that is what you want. Also contrast, color balance, etc. This could come in handy. Supposed to be out later this year. I bet it will be a chunk of change though.

I’ve never seen anything like this before… COOL…

Just modify the pic as if you were focussing on it in real life…

The concept is tantalizing. However, I suspect there are drawbacks yet to be worked out.

First and foremost: I played with the images in full screen mode. When you change the area of focus to an area that was previously out of focus, the image is noticeably grainy. Unless this is just some glitch of the demo, that shortcoming alone renders the whole deal pretty much useless for most any artistic application.

Still, the technology is fascinating.

Yea Charlie,
The full screen mode is kinda disappointing. They won’t say what the megapixel rating is, and I can see why, cause it is different. They only say HD quality. Maybe this is a web demo problem only, like YouTube full screen. ??

I have other questions too, like how would you save/print pics? Do you always have to view it on a computer? But still kind of cool. I doubt I would buy one, but maybe a thing in the future.

Something else I was wondering about, but I guess I answered it. How fast is it? As in shutter speed / stop action. There is a picture in about the middle with a girls face and a boy on a skateboard mid-ollie who is stopped pretty well.

I’ll keep my eyes open and wait for the 2.0 version at least. Otherwise, it will wind up on the shelf next to my Sony Betamax. :-)

More on this technology is here:

http://en.wikipedia.org/wiki/Plenoptic_camera

The image would likely be saved in a proprietary digital format containing the actual sensor data and that of the microlens. From this data, you could likely manipulate data on the camera prior to export or afterwards on the PC.

It would be akin to a tagged image format, whiich contains extra information about a picture with the picture itself. We use similar types of formats in astronomy calls FITS files, which along with the image will contain data about the actual shutter information, image scale, binning information, optics, and object coordinates.

Cool stuff!

I saw some article about that. I think it is a great idea. Don’t have to worry about focus.

The price will be a sticker shock at the begining until they mass produce it.

Incredible. Like something out of Bladerunner. We are living the science fiction dreams of yesterday. Keep dreaming, tomorrow is going to be even more incredible.
