Sensor Summary

Here are are some summary points to consider when selecting your first or next DSLR before we progress to photographing basics next week.

1) Sensors are an important part of selecting a DSLR - some are better than others. Whereas in the past the conventional wisdom was to invest in good glass (lenses) even at the expense of camera bodies, we also used to be selective about film. Today, the glass and the camera are both important because different cameras use different sensors -- we no longer use film. We spent some time discussing sensors. If you are interested in a more in-depth treatment, several books are available.

2) Don't focus on resolution (pardon the pun). Unless you are going to be printing huge images that people will look at up close (i.e., very large prints spanning across pages in a magazine -- double truck, large posters, etc.), 10 megapixels should be sufficient.

3) Pixel density will improve over time. As it does, resolution will also improve. Don't stress over 50% more pixels in the newest model or the other brand next year. Under Moore's law, that seems to apply to all silicon-based technology, it will get faster and better next year at a reduced cost. Get the right equipment now and then upgrade later only if you need to.

Next week, we'll talk about the rudimentary aspects of photography to get everyone on the same page. Then, we can together explore hwo to get more out of our very advanced cameras.
