I am attaching a photo taken with a Canon G10. It was shot on a sunny day at f/5, sRGB, 1/2000 at ISO200. This photo and others like it came out dull and unacceptable. Others, however, came out well. What ideal setting is best for this camera? Thank you.

Looks as though you have focussed on the white property and the camera has set exposure to it.

The exposure is being affected by the light gravel. Set your exposure according to the blue sky, but then you will have to deal with some highlight adjustment in PS. This is a no win situation, except!, it is a great candidate for HDR.

I got it to look pretty good with P.S., and a little work with Topaz 5 adjust. But that's a different story. :)

You needed to boost your exposure compensation. You can do this in anything except Auto Mode. It's the button above and to the right of the thumb wheel. After you press it you will see a scale on the LCD. Use the thumb wheel to dial in the amount of compensation needed. Hope you don't mind. I made a quick adjustment. Your picture is fine it just needs a little post processing. If you don't like it I will delete it. Yes most of the noise in the sky can be cleaned up with a little additional work.

Sorry I just saw the 'no' permission so I deleted the revised photo.

Going by the "f/16 Rule", 1600th at f/5.6 at 200 ISO should give you a well exposed image on a bright sunny day. 2000th at f/5 is very very close but this image is under exposed by about a stop.

Here is the EXIF of your image.

Model = Canon PowerShot G10
Exposure Time = 1/2000"
F Number = F5
ISO Speed Ratings = 200
Exposure Bias Value = -0.33EV


The -0.33EV shouldn't have made all that much difference.

The exposure meters in cameras are not infallible. Fortunately, more advanced cameras such as the G series allow you to check the accuracy of the exposure by using the histogram, which is a graphic representation of the exposure and tonal distribution of the captured image. A little online research should find you a good explanation of how to use the histogram to judge exposure and then you can use exposure correction guided by the results. Also, as mentioned above, small errors in exposure can be corrected with image processing software.

Were you using spot metering?

...perhaps the meter's spot included the white building?

I would have guessed the roadway is about 18% grey, so you could have metered from it.

There is a built-in neutral density filter. I don't recall if the exit information tells if the nd filter is set. Was it on?
