Hi everybody, I'm new to photography and i'm trying to learn a technique for a certain picture that i want to take and any help would be appreciated. I want my subject to be kneeling down and praying while i have a shorter person hidden behind this subject out of the camera's view, moving thier arms up and down to make it look like the main subject has wings. I know that i should be taking the picture during a slow exposure but im not exactly sure what that means... since i am so new at this that im not aware of phtography terms. Also what apeture and shutter speed would be best to perform this type of picture? I am using a Minolta hi-matic s7 camera from the 60's and it takes great pictures but i'm really interested in learing how i can create this paticular effect. Any help would be greatly appreciated. Thanks in advance.
