A trained eye can see a scene and decide the luminosity and thus the WB. How does one evaluate EV. Is it after the shot only, after reviewing the histogram ? Sometimes there may not be time to evaluate the shot and then adjust the EV, so how does one do it ? I know shooting RAW and adjusting after wards in NC is possible. Isn't it better to get a near perfect exposure in the camera itself ? How often do you use EV Bracketing in the field and if the answer is frequently, then which one ? A digital camera underexposes, so does one bracket only upwards viz 0.0, 0.3, 0.7 or higher ? All advice/tips on Nailing the Exposure highly welcomed.
