Re: Aliasing -- DXO wins

One thing I noticed from Mads' original post is the amazing success of DXO at cleaning aliasing.

The last time I investigated this, I compared Lightroom, Capture 1 and Iridient to what the JPEG/TIFF engine in my 50R can do. It wasn't close. Only the camera repaired what you see here on the left.

But look how well DXO did. Amazing. Mind you, it's hit and miss. It cleaned one silo (left) nearly perfectly, but did less well with squat silo on the right.

DXO (on the right) does a much better job with aliasing than Lightroom (left).

My experience with color aliasing is that it is about blurring the color channels.

Convert the image to Lab and look at the chroma channels, what do you see?

Best regards

Erik

Re: Giving DXO a try

It turns out I had the noise reduction turned down in the C1 RAW making for a flawed comparison. DxO still does better.
