When images are presented in court as evidence it is extremely important that they are an accurate representation of what the witness is testifying to. They must also be the highest quality possible so that no questions can be raised as to the subject matter. Here are some general guidelines for photographing for court.
Lighting
Lots and lots of light is essential to great photos. Light is what everything else in this article depends on, so make sure you are equipped with a high output flash. Most professional flashes have an adjustable flash head which can be used to change the angle of the light emitted when the flash is fired. It is important to utilize this feature when shooting a subject. Showing multiple images of a subject with different light sources can often give the viewer a better understanding of the subject.
White Balance
Though light is important, representing accurate colors comes in at a close second. Most photographers leave the color processing up to their cameras by selecting the “flash” setting or (by far the worst) “auto” setting on their camera’s white balance selection. This seems like the simple solution, but in reality it will not produce the desired color accuracy. Most professional cameras come with a “custom” white balance selection. With this selected you take a picture of something white in the space you are shooting (with your flash on!) and select that image as the white balance sample. After that all the images you shoot will have colors accurate to that space. Be sure to do this every time you change the space you are shooting in.
Aperture and Depth of Field
This is where all that light comes into play. When you are shooting, you want to have as much detail as possible. In order to achieve this you need a very small aperture on your lens. Smaller apertures require more light, since less light is being allowed to pass through the lens to the sensor. The higher the f-stop the smaller the aperture. It is ideal to keep the aperture between f5.6 and f11 at all times throughout your shoot. This will allow of the optimal depth of field. Depth of field or DOF is referring to the amount of the image that is in focus when the picture is shot. A larger DOF will have more detail and more of the image in focus, this is what higher f-stops allow.
