Title: Xtrans: Diamond pattern in out of focus area
Post by: Ivo_B on April 17, 2018, 02:39:21 pm: Hi All,

Are there any Xtrans users around? Did any of them already experienced a funny diamond shape pattern in an out of focus brickwork? I guess it is the Xtrans sensor who is confused? See picture.

How did you process this?

I shoot RAW and use Iridient X-Transformer from Lightroom to demosaic the RAF file. After that I finish the editing in Lr and PS. I like the results with Iridient better than letting Adobe demosaic the file with their RAW converter.

If you want help figuring this out, I think you will need to make the raw file available.

Tx for the replies.

This is a jpeg straight out of the camera. I don’t shoot RAW for this kind of photos. Under normally conditions the in camera raw processor delivers pleasant JPEGs, to my taste.

I was thinking it is the red color of the brickwork and the typical Red pixel lay out of the xtrans causing this effect.

I will go back and redo in RAW. See what happens.

Kind regards

Ivo

No fence in the background. :-)
