Here are all the potentially useful images I took of the possible Philadelphia Vireo, taken from the east side of Stevens Creek between L'Avenida and Crittenden Lane on September 24, 2005, at 8.15 a.m. I took the pictures in RAW, with my Canon 20D, and a Canon 500mm f/4 lens, with Canon 1.4x teleconverter attached. Exif data attached to each image shows exposure information. These images were converted to 16-bit TIFFs in Breezebrowser, then cropped and saved as 10-quality jpegs in Photoshop CS2. No further editing was applied. The images were taken of a bird at quite a distance, in shade against a bright sky. The bird images were underexposed as a result, and so to get maximum data allowed by the RAW capture I applied between 2/3 and 1 1/3 stop exposure compensation in the RAW conversion. More details available upon request.
