Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
There's more to it than just "camera and settings". How much light in the aquarium, ambiant, etc will all affect the photo as well. Unfortunately in the case of Aquarium pictures trial and error is your friend!
