One of the most important elements of a composition is establishing the appropriate contrast in the piece, contrast of light and shadow, contrast of subjects and contrast of elemental details.
Often, those in the visual arts use a technique called 'bracketing' or 'stepping' to find the right balance in a composition. The technique consists of increasing and decreasing the amount of exposure, or light in the shot to establish different details and find the best result.
A very beneficial technique that supplements 'bracketing' in the visual arts is known as High Dynamic Range imaging. This technique involves taking the variations of a composition, the lightest highlights to the darkest shadows and merging them into a solitary composition that will have exceptional contrast and all of the positive elements from each variation.
While revisions can be painful, the concept of taking a single draft and revising it into separate directions, applying a lighter tone so the high points are the brightest, then taking another variation and revising with the intent of taking the dark moments and making them the darkest they can be is very beneficial. The end result of creating separate, bracketed, revised compositions allows the creator to merge all of the strongest elements into one HDR Composition.
How do you revise your work? Do you use an HDR technique or do you adjust the individual elements of the original piece?
