(set by the f-ratio and shutter speed) has been made as large as possible subject to shooting constraints. Live histograms and highlight-clipping indicators, which are almost always based on the processed JPEG rather than on the raw data, might indicate highlights are blown when in fact they are not and could be recoverable from a raw file. Therefore, it can be difficult to expose properly to the right without risking inadvertently blown highlights. This problem can often be mitigated by using camera tonal settings that allow the JPEG histograms and highlight-clipping indictors to best reflect the underlying raw data.
