How to Find the Best ISO for Astrophotography: Dynamic Range and Noise

ISO is one of the three major exposure settings in the exposure triangle of a digital camera -- shutter time, f/number, and ISO. Of the three, it is ISO that is probably most misunderstood.

New Tech Totally Eliminates Zoom and AF Noise from Video Soundtracks on the Fly

DSLRs and Compact System Cameras are becoming increasingly capable video capture devices in addition to being solid still shooters. But when it comes time to focus or zoom using the lens' or camera's built-in motor, you're often left with glaringly obvious noise on your soundtrack.

So far manufacturers have tackled this problem by introducing silent focusing motor lenses, but one group of engineers is taking a firmware-based approach that seems to work just as well (if not better) and might someday soon do away with zoom and AF noise entirely.
