Care to share with us? You hear a lot and see so little...
If you don\'t see it, then your workflow or the way you work does not bring it out. I suspect it is like this for the majority of the people out there.
But just because you don\'t see it doesn\'t mean the issue isn\'t real. The compression artifacts can be quite annoying when you start pushing and pulling the RAW files around.
I shoot professionally and use all the big three: Nikon, Canon, and Sony. I do lots of post work (you can check out my FLICKR), and see these artifacts quite frequently.
I\'m not going to go into detail on my personal workflow, but I can duplicate what I see even with DPREVIEW\'s studio tests. And these are just simple Lightroom edits. Imagine taking a RAW file and really pushing it to its limits on what it can do.
I find it interesting, too - what confuses me here is the zoom/crop area, why is it not the same for each of the full photos on top? For a better 1:1 comparison I would like to see the same crop from each of the above photos for better comaprison. Just a suggestion!
Retro - are you referring to the top three rows of photos? They are the same crop area, but if you\'d like I can zoom in more and show you a specific area. It took me awhile to make that comparison image (thinking people would appreciate the time and work I put into making it, but instead some attacked my work and flickr page haha).
I have it saved in photoshop PSD file now and can quickly edit it for a closeup.
