I note you mention the inherent low dynamic range and noise of your SD9 so the potential benefit may be well worth the effort and sacrifice in convenience.

(It would be interesting to see a study testing to see if pushing the ISO to achieve ETTR had any advantages) Under these conditions to retain the shutter speed required the only option for increasing exposure would be to up the ISO even more which seems counter productive. In both cases the ability to reduce possible noise by increasing exposure (ETTR approach) is of minor importance. However I only use high ISO when I have the aperture wide open and need the additional ISO to try and achieve a shutter speed suitable either for being hand held or the subject movement. The most benefit theoretically would be at high ISO settings where the dynamic range is reduced. That's a Kodak White Card behind the Macbeth! No "LED blue peak" there! However, I could have got more DR in that shot (it's just a fr'instance) and, of course, the white balance can be corrected easily and controllably in post.Very interesting, but the camera I use has a high dynamic range therefore an increase of up to 1.3 ev of potential exposure gain is for me not as important as the insurance it offers against channel saturation. That's a Kodak White Card behind the Macbeth! No "LED blue peak" there! However, I could have got more DR in that shot (it's just a fr'instance) and, of course, the white balance can be corrected easily and controllably in post. My latest LED floods, however, are a different matter: By coincidence, 10 am Local Solar Time provided perfect light, no WB needed. No noise reduction applied other than the raw converter unavoidable default and a tiny highlight reduction (-0.2, Sigma Photo Pro) got the highlights just right. Note the (for SD9) lack of noise in the shadows. But the result, for me, is worth it for those important shots like, for example, my real-world well-house: The procedure to get a UniWB custom setting in your camera is not for the faint-hearted. So, by using UniWB, more trons in the sensor wells is a good thing. It's of special interest to me because the raw-only Sigma SD9 is neither noted for its dynamic range, nor for its noise performance.
Rawdigger shutter count how to#
Here's a good description and how to do it (caution: dcraw needed). Which, in turn, means that the camera histogram is not lying to you, allowing you to expose to the right with confidence For those who don't know what that is, it's a setting of the cameras custom WB such that there is effectively no WB effect on the camera preview image.
