While digital cameras offer the potential to bring back better pictures more easily, I find many aspiring photographers are overwhelmed and confused by the technology and abundant options for shooting. It's time to focus on the essentials, and then take advantage of the technological enhancements.
Digital cameras are still based on the use of an aperture and a shutter for both exposure and creative control, just as film was. Working with the basic principles of each still applies to every photograph you take. Exposures are all modified by adjusting the diameter of the aperture and the speed of the shutter. For determining creativity, though, the key is to remember that changing the aperture’s diameter determines the amount of depth of field, and adjusting the shutter speed determines how motion is portrayed.
Working with the automatic modes on today’s cameras helps make getting a good exposure as easy as it’s ever been. First, I’ll take a photo and visually check it for composition on the LCD. With the ‘Highlights’ feature turned on, any overexposed areas flash and show up right away. Next, check the histogram for more detailed exposure information. The extreme left of the graph is the black point, and the extreme right is white. If any portion of the graphed line touches or piles up against the white or black ends, some sections of the image are either pure white or black and have no other detail. There is no ‘perfect’ curve for the middle, the graph simply reflects varying amounts of image detail at different tonal values.
