How to use a Digital Camera as an External Light Meter
Why buy a separate meter when you can buy a complete camera with a built in meter for less than a separate professional meter? Yes, for the same price or less as a pro meter you can buy a digital point-and-shoot that weighs less and lets you preview the images for color and contrast. ......
