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.
You discover a whole new world when you take an “up close and personal” look at minute objects—colorful insects, the details of a leaf, or the stamen of a flower. This type of photography can be very gratifying, but macro photography takes time, patience and the proper equipment. You can shoot some images simply by using the close-up setting on your digital point-and-shoot or SLR. But there are other options for the serious close-up photographer: close-up lenses that screw onto the front of your lens like a filter, extension tubes, or macro lenses. Upload your image and share your inspiration.
