Besides a Camera, What is the most indespensable piece of equipment to photography and why?

besides a camera one indespensable piece of equipment to photography that is most important is what you are taking a picture of. this is one of the most important things because it determines how good your photograph comes out and if it is appealing to others. another important piece is flash meters. For ambient light readings, the meter in your camera can be quite sufficient. Flash metering is another story, especially if you are using flash to fill backlit subjects or darken background areas to place more emphasis on the subjects in the foreground. You can always shoot test exposures and review them on your camera’s LCD, but a more professional and certainly more precise method of establishing accurate flash exposures is by using a flash meter.One consistent characteristic of flash meters is that even the least expensive of them can establish both ambient and flash exposures—reflective or incident—down to 1/10-stop in accuracy, wirelessly or tethered. When you are dealing with the broad contrast range presented by men’s and women’s wedding clothes, it is important to consider the benefits of taking incident readings with a handheld light meter. Incident readings measure the amount of light falling on the subject, rather than the amount of light reflected from the subject. In most cases, incident readings, which read the light in terms of neutral, 18% gray values, will provide you with accurate average exposures regardless of whether your subjects are wearing white gowns, black tuxedos or brightly colored bridesmaid dresses. Sekonic goes one step further by offering the option of incorporating PocketWizard wireless triggers into many of their flash meters, which enables you to “walk the set” in order to establish flash and ambient exposure readings from any position within the frame. At B&H, we stock a variety of flash meters from companies including Sekonic, Gossen, Shepherd/Polaris, Interfit, Wein and Kenko.
