This question already has an answer here:
My digital camera has a bracketing feature, and I set it to three shots, with the bracketed shots being 2/3rd +/- its calculated exposure. I find that that tends to get me one shot with the colors and tones I more or less expected.
However, I noticed that in post-production, I have great leeway in adjusting the exposure, the lights, darks, highlights, shadows, colors, etc. etc. It made me wonder if bracketing is really necessary, when I have all this control after the shot.
Does bracketing get you anything in the era of digital photography? It does come at a cost-- my card space is reduced by 2/3rds (for my settings) and I treble the wear and tear on my shutter. So if it's not useful, I should turn it off.
The only redeeming effect I think it might have is that, if one of the bracketed shots is clearly better than the others, I might not skip over it in deciding which images are the good ones.
