Sure, there are some magical photos taken with a disposable 35mm or with a point-and-shoot digital, but those are more random luck than the product of a skilled photographer expertly manipulating the shots.
Since the advent of point-and-shoot cameras, photographers of all skill levels have tried their best to capture awe-inspiring images of brilliantly colored fireworks painting a pitch-black sky.
The device produces photos that are above average for a point-and-shoot camera of its size and it offers additional features that are not available on most digital cameras in its price range.
Point-and-shoot cameras have a single, fixed lens, which often has an optical and a digital zoom function that can be changed between wide angle and zoom settings with the touch of a button.
Designed for people who are interested in taking their photography a bit beyond the point-and-shoot level, yet still want a pocket-sized camera, the S90 is loaded with useful features.
However, satisfactory results can also be achieved with point-and-shoot digital cameras as well, assuming that they have enough manual controls to override the automatic settings.
Having a single lens reflex (SLR) camera will go a long way to help you capture details of the moon's surface that you would not be able to with a basic point-and-shoot camera.
Digital SLRs can offer you more freedom than point-and-shoot types, but the trick to making the camera work for you is learning how to use all of its features.
You can still achieve a good deal of success with a quality point-and-shoot, however, so don't feel that you absolutely need to invest in an expensive digital SLR setup.
Canon also introduced a "Live View" feature on the 40D which allows the user to use the LCD display to view the image in the same way a point-and-shoot camera does.
