Many photographers, particularly at camera club level and in special interest groups in social media, are constantly striving to get perfect exposure, perfect sharpness, perfect colour.
|'Dimi' - Under-exposed 4 stops|
|-6 degrees - shutter froze|
|Over-exposed 4 stops|
|Light source - 1 mobile phone|
There's two ways of doing it. The 'old-school' method is to use M exposure and simply use your aperture and speed controls. The second method is to combine exposure modification (your + and - button) in combination withe auto exposure bracketing.
For example many Nikon DSLRs give you a bracket range of a whopping nine stops! Combine that with your + and - modification and you can dial up + or - 12 stops!!
