Exposure Assistant is a handy photographer's utility that helps calculate correct exposure settings for those times when the in camera exposure options are not flexible enough. It is primarily beneficial in two situations:
- DETERMINING LONG EXPOSURE SHUTTER SPEED VALUES: Most modern cameras will not calculate shutter speeds greater than 30 seconds. Most of the time this is not a problem, but what about those times where you have set up your tripod at dusk to get the perfect shot, you've set the ISO to 100 for maximum quality, and the aperture to f/16 for maximum depth of field. All of sudden your camera is flashing "30" meaning that the shot will need a shutter speed longer than 30 seconds, but your camera will not do it automatically. In this situation, with Exposure Assistant you can switch to a full auto setting, input the values that the camera calculates and then enter your desired F-stop and ISO. Exposure Assistant will calculate the appropriate shutter speed. You will have to use the 'bulb' (B) setting (and a remote switch of some sort), but you will not have to guess how much longer than 30 seconds the shutter speed should be.
- USING AN OLDER CAMERA WITHOUT A BUILT-IN LIGHT METER: Though most of us primarily use digital cameras these days, inexpensive medium or large format photography using older film cameras is still a very viable (and much less expensive than digital medium format cameras) option. But many of these cameras do not have a built-in light meter for determining exposure settings. An easy way to overcome this is to use a small digital camera to determine the correct exposure settings for the older camera. Unfortunately the available settings on two different cameras (especially cameras from different decades) often do not neatly line up forcing one to do some quick calculations to adjust between the two. With Exposure Assistant you enter the basic exposure settings as determined by the digital camera and then it transposes those settings for you to values that are available on the older camera.
