It was not that long ago when Lytro stunned to world with a camera that can re-focus in post production. This was quite a revolution as till then, the focus point was at the time when the shutter opened, was the focus pint and that was it. Millions of photos ruined by being almost in focus but not quite and Lytro aimed to change that. The hype, however, did not convert into a fed.

Now researchers in Saarland University in Saarbrücken, Germany extend the idea of Lytro to enable post production control of almost any possible aspect of photography including: exposure, light-temperature, focus and polarization. (and even a bit of spatial control) They call it The KaleidoCam. This video explains how it works.

KaleidoCam is not a camera per-se but a combination of hardware and software. The hardware “sits” between the camera and lens, and splits each incoming image into several frames differentiated by a wanted aspect, say exposure or polarization.

Then, a piece of software recombines those separated images into a single file with elements that can be controlled in post production.

Here for example is an varying exposure image with the hardware in place.

KaleidoCam - exposure

And here is a sample with varying polarization

KaleidoCam - Polarization

Since the KaleidoCam attachment uses the native camera sensor, the more pixels the sensor have, the bigger the image will be. While Lytro is limited to 1080px1080p (or 1.2MegaPixels), the KaleidoCam at its current 9-split can potentially extract 4MP photographs out of the 36MP D800.

    Well I already guessed while reading/watching the videos, that due to physical splitting the resolution must lower drastically.

    But the possibilities are very nice, like an “ultra-raw” picture, where you can change everything afterwards. Great for speed-shootings where you would mess with autofocus (movement-blur wont be changed by this).
    You would need a 72MPcam or higher, to get really nice pictures.

      I don’t think that your math logic is correct. 1.2 mp is 1080p so a 4mp file is more then enough for 85% of work shown on the web today. Even if your printing you can get great 4×6. All in all I guess this is a good reason for the mp war to continue:-)

        Well 1080×1080 = 1,2MP
        an 1920×1080 (fullHD) is about 2MP
        But you can’t zoom in digitally (to cut a part of the image you want to use).
        You can get the 4MP with a 36MP cam, My alpha 55 “just” creates 16MP pics. Therefore I couldn’t even get full 2MP.
        So yes, megapixels war should go on, if you ask me :)

        But dont’t get me wrong, besides the digital-zoom-thing I agree, that a pic with higher resolution than the displays resolution won’t look better at all. ;)

    couple this with 360 panoramic imagery and you could have the ultimate tool for post-shoot reconfiguration.
    I think the HDR capabilities would be the most exciting part for me. Single shot HDR for moving objects would be incredible…
