Bracketing is when you make several exposures of the same exact scene, some over and some under what the light meter has calculated to be correct.
INSTRUCTIONS:To bracket, make one exposure as your light meter has calculated as correct. This is called "Normal" 1. Set the "camera" to Normal f5.6 @ 1/60th and click the shutter release. This is the same exposure as the Original Exposure on the left. Next, adjust the aperture or shutter speed to over expose by +1/2, +1, +1 1/2 and +2 stops. 2. Set the "camera" to +1/2 (f5.6 @ 1/45), +1 (f5.6 @ 1/30), +1 1/2 (f5.6 @ 1/20), +2 (f5.6 @ 1/15). Next, adjust the aperture or shutter speed to under expose by -1/2, -1, -1 1/2 and -2 stops.
2. Set the "camera" to -1/2 (f5.6 @ 1/90), -1 (f5.6 @ 1/125), -1 1/2 (f5.6 @ 1/180), -2 (f5.6 @ 1/225). Notice the affect these changes have on the overall lightness and darkness of the image. Also notice how detail in the highlights and shadows is affected. For a good exposure you are looking for good detail in the highlight and shadow areas of the image. Bracketing allows you to select the best possible exposure after development or processing.
