Just returned from a photo workshop at Ricketts Glen near Wilkes-Barre, PA. Terrific place with 22 named waterfalls. I used a G1 with 14-45 lens and a linear polarizer. I shot jpegs with sRGB color space and the WB and film mode settings I have described elsewhere. I felt the camera worked like a charm, and that the results held up well against the other attendees, who essentially were either Nikon or Canon users - there may have been one Pentax in the group. It was interesting to me that we all had to submit our images for the critiqueing session as jpegs and in sRGB color space, for results to be easily and accurately displayed on the screen. The instructor then proceeded to use Lightroom and retieve lost detail in the highlights (waterfalls), make other and varied adjustments, all on our jpeg images - and he did it quite sucessfully, I might add. Working with this equipment in the field, where you had to hike down 700-1000' mostly over a mile and therefore very steep, and then hike back up again, makes you really appreciate this camera format. And when the results, from a technical standpoint, were indistinguishable from those carrying lead anchors, this tired old body was very pleased with the results.
