Two or three girls with their faces pressed together is not a good photograph. To say that it is not a good photograph is to suggest that there is a good picture and sure good is subjective but a few criteria points survive. These include, color, composition, and a story.
The picture needs decent colors, it needs a theme of colors and not washed out.
The picture needs composition that was done on purpose. the subjects in the picture we're placed randomly, a decision was made to put something in a place.
there needs to be a story about the picture. Something happened before the picture and the objects in the picture are working on getting to another point. this is true for people in the picture. Photos of texture or inanimate objects need not apply.
Hold out your hand an take a picture of you faces and your telling me what eyeliner you wore to the party. Where are you? How did you get there? Where is the top of your head?
Take a candid picture of some one that doesn't know its coming and they don't know you took it afterwards, if nothing else there will be a mood around the person wether you meant for it to look that way or not.
and turn off your flash and turn on the lights
(and why do we need to turn our faces to the to the side and give a hint of a smile. this is the most over played pose. Some teeny bopper broke in to the magazine model poses and broke out an easy one and passed it around to her margarita friends.)
