Many years ago I purchased a nice DSLR and photo quality printer for Christmas for my wife. The next step was to teach her basic photography. What followed was a series years of blurry photos, wasted ink and paper - until now. I happened to stumble on something called the camera simulator. With it I have been able to show her how to configure the camera and make better photos. I've even explained to her how these basics apply to her point'n shoot camera. She was so excited for things like ISO, f-stop, shutter speed, all suddenly make sense. So if you've wanted to learn to photograph or struggled to show others how to use their camera, now you have easy access to all the tools required. Two thumbs up! I hope others find it helpful.
