Everyone has a subjective view on photographs. Some might look at the technical realization - white balance, composition and sharpness, while others might choose emotional portraits or prefer only reportage photography.
No matter what type of photography it is; colored or black and white, portrait or still life, fashion or street style, landscape or wild life, you will always recognize a good photo, because it won't be just a perfect shot. It will catch your eye and it will make you feel the connection with a place or a person. It will tell you a story you will always remember.
