根据下面资料，回答题 Are all your photographs good? Be honest with yourself. Aren't some of your pictures too dark, and others too light? How many times have you thrown away a photo? We, the Fine
Photograph Club, can help you. We meet every Wednesday in our comfortable club room in

Photography is now a big business. Did you know, for instance, that there are 15 million
cameras in our country? And that 700 million photographs are taken a year, more than one-third of them in color? Think of the amount of photography in television, the cinema, news-papers, books, advertisements and so on. In modern life people learn a lot from pictures, so photography is more and more important. It is also more complicated and more expensive than it used to be. You may only want to take good photographs of faces and places. If so, we can help you to get better results. You needn't waste any more money. If you want to learn more about photography and how it is used, join the club please. You won't be disappointed.
