A7R3 and the Result of Pixel-Shift
« on: November 21, 2017, 13:24:02 »
Here is the article on Pixel-Shifting:

Ony's New Imagine Edge Software can now be downloaded here:

They have posted what I imagine is the final software for processing the pixel-shift images. The pixel-shift technique in the camera produces four raw images. Are we supposed to post-process those images before we submit them to the software?

My main question is this: If the cameras takes four images in raw and then processes them, what format are they returned in: JPG or TIF? I guess it can't be raw, but that is what I would like to have, of course. Anyone know?

You shoot raw, the software takes raw and delivers a new raw

Thanks! So the final image is raw if I read it right.

RAW is often just a thinly disguised TIFF

You are right that fractional pixel shift - either 1/2 or 1/3 pixel - as a form of image enhancement has been around for years.  What people imagine whole pixel shift is doing is one of life's mysteries.
