ETTR, Exposure to the Right, results in an exposure that maximizes captured signal-to-noise and provides the best information from which to base a final image. This can be achieved in several ways. ETTR images of scenes with low-DR and high-DR require very different processing steps.

We face many problems on hard drive since we are using it from several years, but these problems are likely to be removed by solid state drives. SSD's are much more faster, reliable and convenient for speed loving users etc.
