With its nice mix of consumer and professional features, the EOS 30D, the first of Canon’s two prosumer models, is worthy of any photographer’s gadget bag. Canon has never rested on its laurels, and refines, tweaks, and modifies each new addition to its catalog FIG 3.6). The 30D features an 8.2 megapixel CMOS sensor, the [...]

“It was surprisingly difficult for me to fully embrace digital. I had such a familiarity for film; there’s nostalgia there, but there’re some advantages, like dynamic range. I’ve always liked to think I’m willing to change, but making the total switch to digital was one of the toughest things I’ve ever done. Younger photographers, who [...]

File Accessibility
The question of how to easily access and store files is frequently raised, and is another situation that should be studied by each photographer, then implemented according to individual needs. Regardless of how you access your files, keeping your primary computer’s hard drive full of files you might work on is not the best solution. [...]

Shooting RAW
Another shooting option is to shoot RAW. Unlike the .jpg file format, in which the camera makes the processing decisions based on the parameters you set, a RAW file is the equivalent of a digital negative, and you decide, via Canon’s Digital Photo Professional software (supplied with the camera with free updates available online) how [...]

Resolution and Compression
The reproduction quality of any image is ultimately tied to the number of pixels that comprise that image. Pixels, shorthand for “picture elements,” are present in the millions in all of Canon’s cameras, even their amateur snapshot cameras, as it takes a million pixels to equal 1 megapixel. Thus, a 16 megapixel sensor contains 16 [...]

Reciprocity
Reciprocity is the rule that states that if, beginning with the correct shutter/aperture combination to yield a perfect exposure, the shutter speed is adjusted in one direction (faster, for example) and the aperture is adjusted correspondingly in the opposite direction (opened up, for this example), the exposure will be the same. Let’s say a correct [...]
