Don't be bashful! If you want comments, give comments. You don't need to be an expert photographer to express your opinion about the work of others. You don't need to go into great depth. A simple remark about cropping, composition, color, subject matter, etc. can be of just as much help to a budding photographer as an in-depth critique.
Every now and again, you’re presented with a scene taken out of context. Without the necessary surroundings, and on an odd scale, how do you know what the photo is of? There is a special kind of pleasure that can be derived from presenting a photo to your friends that makes them ask, “That’s gorgeous! What is it?” Leave them guessing for a while, and eventually, you can reveal your secret. For this assignment, take an everyday object that most people are familiar with, and try to capture it in such a way that an observer won’t realize what it is — until you tell them.
