I think I already wrote something about it, anyway- High Dinamic Range - is a tool (part of CS PS, or several separate programms) - that mixes together several tripod obtained picture with the same apperture and different shatter speed.Usually - if you have bright sun and deep shadows - you can not get both (look zonning theory by Anselm Adams). Usually you can be good in 4 clicks of diafragme range inside of the pictures. Using HDR transformation (file-authomatic-HDR in PS) ypu get several pictures with different shatter speed - for shure you will see only sky and sun on one of them and only ground inside shadowed area with several (the more the better) pictures in between. If you are lucky and your tripod is steady and no high wind moving clowds - you get a good picture from the first pass, if you are not lucky - you have f vords generating process of masking different areas or forget the issue. Usually this is easy enough. |
