GH3 optimized RAW hi-ISO and wide DR files
6 months ago

I found some nice GH3 RAWS this past rainy weekend, and loaded the new beta ACR 7.3. First two
are ISO 6400, the third 200. Processed to my taste in ACR 7.3 beta/PS CS6. Major ACR settings
shown. The gallery views are much larger.

#1 - Exp. +0.5EV, CT 2700, Highlights -33, Shadows +50. NR: Lum 65, Chroma 30

#2 - Exp +0.25EV, Highlights -30, Shadows +20. NR: Lum 35, Chroma 30

#3 - Exp +0.35, Hilights -100, Shadows +100, Clarity +50

In CS6, all images had final levels/curves adjustment; #1's and 2 had minor color tweaking. A 12x16" print I made of the sandwich shop image is very presentable, with minimal noise, good detail, very good colors. I'm impressed!
The 100% JPG images accompanying the ISO 6400 RAWs showed amazingly little noise, good preservation of detail, and very good color. This new JPG 3-D NR Venus engine is impressive!
In the last, big DR gain recovered in RAW, with detail seen in the shadowed undercarriage of the righthand rail car and in the ceiling of the building, with both better cloud and outside building detail. Histogram shows no blown highlights.
As good as the GH2 is, I'm satisfied that these results are pretty far beyond its reach. The site also has three comparo GH2/3 sets of full-sized JPG's. GH3 colors are MUCH better - warmer, more Oly-like.
