Sony E 10-18mm f/4 OSS vs Other APS-C W/A lens - waardij - 08-08-2013 It all depends on context. Dynamic range is often used as a description for an input property (the subject). In that context a sensor can have a large dynamic range, capable of capturing a subject with high dynamic range. Contrast can be used both at the input and at the output (screen, print). Contrast is more a qualifier whereas dynamic range can be an objective property (which can also be true for contrast, but it is often not used as such). For example a print can simply not contain the dynamic range of many subjects. When you would want to print a high dynamic range subject without manipulation, it would become a very flat print (low contrast). Now assume that a landscape with a bright sky is photographed; with a digital neutral density grad filter in for example photoshop, the luminosity of the sky can be brought down to match that of the foreground. In this way the dynamic range of the image is reduced, but the perception of contrast need not have changed. And there are tone mapping tools (or just using masks), that help reduce the dynamic range of the output, without changing the perception of contrast. Maybe the most extreme example are paintings. Usually the luminance range in a painting is small (no dark shadows), while the perception of contrast can be very natural, and independent of the dynamic range of the subject.

The white point has shifted due to the NDG filter. Quote:but |
