I think rjaywallace has the right idea, i.e. exposure triangle. Your exif data shows f-stop=5, exposure=1/1250 at ISO 200 with auto WB and shutter speed priority. I suspect these settings were not enough to get a good exposure and just produced an underexposed image. With the exposure and ISO set, only the aperture can change. For your lens at 165mm, the aperture of f5 is likely wide open and can't open any further.

To estimate an adequate exposure, I go back to the sunny 16 rule for overcast days, i.e. f/8 @ 1/ISO. Using your shutter speed and ISO, you would need an f-stop between 2.8 and 4. A shutter speed = 1/600s or ISO=400 would likely have returned a good exposure and possibly a good white balance.

Even on cloudy days, the ambient light can change rapidly, requiring changes in exposure settings.

You may not have to invest money in a program, Canon DPP that comes with your camera can fix these things easily, especially if you use raw (.CR2) files. You will however need to invest a little time in understanding the issues and using the software.

Thanks Peter,
That’s the direction I’m leaning towards.

Last week I had issues with the auto white balance when shooting leaves on the forest floor. The shot was way to blue. It took a few shots find the correct setting.

The white balance was in automatic, and the majority of the day was very overcast with little sunshine. Out of 200 + photos taken that day about 4 came out with the blue tint.

I do have different settings, and jumped from one to another, but they're pretty close to each other. I'll take a closer look at my WB.

Thanks to all of you.

Even if JPEG, it should be relatively easy to fix with the proper post processing with software.
