The main discussion in this week's show focuses ISO settings (and how far you can go with them). I also revisit the memory card fiasco from last week and touch on the new WiFi cameras offered by Nikon and Canon.
Sometimes referred to as film speed, ISO speed is actually a better term for expressing the light sensitivity of your digital camera. ISO stands for International Organization for Standardization. This entity has established many standards, including the light sensitivity of photographic materials. If your camera has multiple ISO speed settings, then you can use these adjustments to increase the light sensitivity of the image sensor. The default setting for most digicams is ISO 100. This is the speed setting for general photography. If you’re in a low-light situation and need to increase the sensitivity of you image sensor, change the ISO Speed setting from 100 to 200, 400 or even 800, if necessary. Each setting is the equivalent to one f-stop of light.
The general rule of thumb is to keep your ISO setting as low as possible on compact cameras (100 or 200), but understand that you have more latitude with Digital SLRs, which have larger image sensors and more robust electronics. I've had good luck with my Canon Rebel XT at ISO 400 and 800.

If you do end up with an image that's nosier that you'd like, here are some Photoshop plug-ins to help you correct the image:
