Here is a quick follow up to last week's post on Sigma's upcoming DP Quattro cameras. Sigma explains how it works below:
If that makes no sense to you, it breaks down like this: each color layer actually records data for all three colors, but "concentrates" on only one. Through some complex algorithms, the camera is able to piece together full resolution images for each of the three layers, despite only the top layer being 20 megapixels (the bottom two are five megapixels each).
It will be interesting to see how this works in practical use. It will be interesting to see how image quality compares between the Merrill and Quattro cameras. I'm looking forward to the release of this camera series, although it will likely be awhile before I'll be able to get my hands on one.
