Self

Here is a self that i made with "old" equipment, a 6 MP Canon 300D.
The 300D was my first digital slr and my first step to serious digital photography.
In the meantime people seem to think, that it not a real camera, if it has less than 12 MP, Canon offers a new 7D with 18MP and i am sure, that in a few years all consumer dslrs will have more than 20 MP.
But nobody really need's it. :-) 4 MP is in my eyes almost enough for most of the users. And many users are obviously forgetting, that it is not just the number of pixels, but its "quality". On the market of compact cameras we already learned, that a 12 MP cam has in many cases less image quality then the previous model with 8 or 6 MP, because the level of noise is rising with the number of pixels, especially on a small sensor.
So the number of pixels is absolutely not the only factor for a sharp image.
You can f.e. raise the quality of your pixels with the use of a tripod. (I would say, that you can increase the image quality of a 6MP dslr to "felt" 8MP, only by the use of a tripod.) If you are searching for the best possible quality, you should not use the open aperture, or a very small aperture - most lenses have the best quality at f 4 or 5.6 - and you can "increase" the quality by using a fixed focal length lens. No zoom lens can reach the quality of such a lens.
Last not least you should use good filters, f.e. a polarization filter and shoot in the RAW-format under good light conditions.
You see: If you are working carefully, you can present excellent results even with an "old" camera like the 300D. A good image idea/composition is always much more important for a good image result, than the pure resolution of the camera sensor.
And the data files are wonderful small, a 4GB CF-Card in a 20D or 300D allows many hundrets of shots in RAW-format, so there is no reason to bann the elder cameras from your camera bag... ;-)
