Exposure problems with Digital Rebel

(a) The attached picture looks like it could be suffering from lens flare. A general lightening and loss of contrast due to bright stray light on the lens. A lens hood would help a lot. (b) Exposure should ideally be based on ambient light levels, but camera meters read only reflected light which can vary depending on the relative darkness of the subject. The camera meter is calibrated to an average 18% gray tone. If the subject is darker than that and fills the viewfinder, as in the case of this house wall in shadow, then the meter is apt of overexpose. The algorithms used with the DRebel's evaluative meter usually do a good job compensating, but can still fail. (c) Another possibility is maybe instead of using the evaluative meter you used partial metering or centerweighted metering instead? These metering modes would require you to use the exposure compensation to correct for subjects that are lighter/darker than average. (d) Have you inadvertently set + exposure compensation? This setting will remain after turning off the camera, to cancel it must be manually reset to 0.

Thanks for the response Jon. I think I have several problems. a. I didn't have on a hood. Will need to buy one. c. Did use partial metering. Apparently it automatically sets to that in the creative zones of this camera. d. did inadvertantly have it on +1 exposure. I would have never thought to check all of these things. Thanks for sharing your expertise. You are what makes this web site great.
