Pandas and Bamboo

At the end of yesterdays' post I mentioned that your digital camera's ability to capture very bright and very dark tones is called it's Dynamic Range and it decreases as you increase your ISO. (Something I didn't know until just this week.) One of the challenges in shooting this kind of exhibit is that most things are very dark except for the lit exhibit. You need to watch your exposures very carefully because it is a tough job for the camera to get it right. This might be one case where manual exposure mode would work well.

The most important tool in this kind of situation is to shoot RAW. When your camera records images as JPG it has to process them and make a decision all by itself about what highlight and shadow detail needs to be kept in the 8-bit JPG format. It has to make compromises and you as the artist won't have only limited ability to override those decisions later. RAW gives you more freedom.

You need to have a processing workflow on your computer to work with the RAW images. This means a software program that lets you easily work with the RAW data. I suggest Adobe Photoshop Lightroom or Apple Aperture.
