This was photo was take with a Panasonic G2 mounted with a Pentax Super-Takumar 55mm F1.8 which came as the standard lens on a Pentax S1a which I purchased used in the early 1970s for my father as a replacement for his Petri Rangefinder. At the same time I also picked up a Gossen MultiBeam solid state meter from Clyde’s Camera in Seattle which was famous for having a warehouse full of vintage gear in mint condition. This replaced my father’s ancient Seconic photocell meter which was not super accurate.
This image was taken about 6:30pm on 3/31/12 at Fisherman’s Wharf in Seattle. It was captured raw and developed in both LR2.7 (top) and LR4 (bottom). You need to open both of them to see difference. Notice the rolloff to specular highlights. The LR4 version is a significant improvement over LR2.7. The transition between the textured white and the 100% in all three channels is pretty ugly in LR2.7. The all white center is larger and there is more color distortion in the transition area. This effectively increases the dynamic range of the G2 for Lightroom users. This is NOT simply a difference in the curves applied during development. There is actually more recoverable highlight information in the LR4 version. No matter what you do in development you cannot match the highlight results in LR4 using the older version.
