Once the images from these cards are loaded into the computer, the cards can be erased and used over and over again. Critics of digital cameras point out that the image resolution cannot match that of a conventional 35mm slide, and this is technically true. Before the trip, I worried that roughly 300 exposures would not be adequate to cover three weeks of shooting. But the ability to review, edit and erase unwanted images left me highly satisfied with my take at the end of each day. Using a digital camera in the field isn't too different from using a conventional machine.
Most digital cameras resemble sophisticated point and shoot models in their design.
To my thinking, modern digital photographers enjoy the benefits of using a good rangefinder combined with a view camera. The LCD window is highly reflective in bright sunlight and difficult to use. A half-yard of black material serves as a focusing cloth and brightens the image. I've also fabricated a viewing hood from a 4-oz. However, several of these were slightly fuzzy due to camera movement and slow shutter speeds.
