I was at the dog park, it was bright overcast-great for not too bright, contrasty pics. I was using P mode on a T3i, 75-300 lens, usual skylight filter, ISO 200. The camera pretty much was running 1/800 almost wide open.
The pics look greyish. Certainly not white. The dogs are in good focus. What went wrong?
The high reflectance of the white screws up the metering system in our camera and told it to close down two stops to compensate. So, mind over meter, you need to open up 2 stops.The same you need to do if you are photographing black horses. You need to close down to stops.
