![]() ![]() The thing with a camera’s dynamic range is that those exciting numbers become valid only when the signal reaches the maximum that is, the exposure is the hottest possible for the given camera at a given ISO. Applied Shadow Boost and +1.67 EV exposure correction.Īs we can see, shot #4152 exhibits significant noise everywhere below midtone. Zoom into shot #4152 that was exposed according to the in-camera exposure meter. Applied Shadow Boost.Īs we can see on to the RAW histogram for shot #4153 (Figure 2) the capture definitely has more than 11 stops. Zoom into shot #4153 with optimal exposure for RAW. We opened them both in FastRawViewer, applied Shadow Boost to both of them to open the shadows, and applied +1.67 EV exposure correction to shot #4152 (the one that was exposed according to in-camera exposure meter recommendation, so that both of the shots had the same overall brightness). Matrix metering seems to have gotten fooled by the specular highlights on that white dome, hence it underexposed a little more than usual. The other shot (#4153, Figure 1.) was exposed 1 2/3 EV hotter (spot-metered from white dome, for the procedure to determine the amount of correction please read on, or you can simply bracket). We made two shots of the same scene – one (#4152) was exposed according to the in-camera exposure meter set to matrix metering mode. Shot exposed 1 2/3 EV hotter than the in-camera exposure meter suggested. ![]() According to Sekonic spot-meter, it is wider than 11 stops:įigure 1. Here is a typical wide dynamic range low-light scene. Let’s start with one of the problems, which arises as a result of non-optimal exposure for RAW. But now we need to explain what we mean when we say, “optimal exposure for RAW”. And here comes the immediate question – how can one use such a treasure to its full potential? Optimal exposure for RAW is the answer. Suppose you have read somewhere that the dynamic range of your camera at a certain ISO setting is 11 stops.
