Joining Bart this month are Mark Pouley from Twin Lakes Images, Antonio Rosario from Switch to Manual, and Gazmaz from the MyMac Podcast. With the giving season freshly behind us, January seemed like the perfect month to start as two-part series on understanding our cameras. All our cameras, regardless of manufacturer, share the same basic groups of features - they all have different modes for metering light, for focusing, and so on. In this first part we focus mostly on exposure and focusing modes.
