I feel that now is as good a time as any to research exposure bracketing. I have heard and seen it mentioned several times but I have never really been 100% sure what it really means.
Exposure bracketing is the technique used to ensure that photographs are correctly exposed particularly in more awkward lighting situations.
Before taking a photo the camera's light meter will automatically choose the aperture and shutter speed that it thinks will produce a correctly exposed photograph. With exposure bracketing two or more photographs are taken, one which is more under exposed (to a negative exposure compensation) and another which is over exposed (to a positive exposure compensation) in accordance with the camera's light meter.
The reasoning behind exposure bracketing is that the light may deceive the camera into thinking that there is too much or too little of it available in the scene which would result in the image being over or under exposed. By taking several shots the photographer can be sure that this has been compensated for.
Many cameras now have auto exposure bracketing (AEB) so that in theory if I was to select this option then the camera will automatically take three shots for me........under exposed (usually by -1/3 EV), correctly exposed and over exposed (usually +1/3EV).
Now that I have a better understanding of what this means I intend to experiment now. I have seen examples of other peoples work who have used expose bracketing and then loaded their shots onto Photoshop. Using the layers setting they layer up the image erasing over or under exposed areas and have then ended up with some brilliant photos.
