My camera is 24 megapixel but I find the photos are too large ( pixel wise) to post on here and need a lot of down sizing. Unless you're careful you can finish up with an odd looking picture.
The good thing about the 25 MP size is the ability to print large photos without pixelation, even larger than A3 depending on the MP the printer can handle.
Good luck with messing with the settings Frank, it's half the fun and better than using photoshop to enchance or spoil the photo.
