DSC00308.jpg

This photograph by Shirley Kilpatrick was taken in Keswick using the Alpha 100 with 18-250mm Tamron lens and programmed exposure at ISO 100. The AF was set to wide area focus, and has locked on to a near-infinity setting which provides enough depth of field for the walkers and lake shore. Either this, or there is a slight degree of back focus. The exposure of 1/200th at f8, ISO 100, agrees with what we would normally expect in full clear sunshine at 5.00pm in mid-September at this location (Derwentwater lake puts a lot of light back even if the mountains take some away). The file is converted from .ARW raw using Adobe ACR 4.2. Parameters are: WB As Shot, 0 exposure adjustment, 0 Recovery, 0 Fill, Black 4, 0 Clarity/Vibrance/Saturation. Sharpening is set to: Level 25, Radius 1, Detail 50, Mask 0 and Noise Reduction to Luminance 0, Colour 0. A chromatic abberation correction of +18 Red/Cyan is applied.

The next image, taken at the same time from a very similar position, is by me using Canon EOS 40D with 70-200mm f4 IS USM L-series lens and identical ACR 4.2 processing except for exposure and black point - see the caption. Both are Level 12 full size JPEGs so you can see the detail and quality of each file.
