You will get two answers: absolutely yes and absolutely no!

Those the argue for keeping ISO at base and brightening in PP say that for ISO-less cameras you get no gain in SNR by raising ISO. They say that you can do better brightening in PP with the enhanced algprithms available in programs like Lightroom. Also you get greater headroom for highlights.

Those that argue for using the ISO setting in camera agre with the above but make the additional observation that pushing brightness in PP results in loss of bit precision and the risk of posterization. They advocate setting exposure using ETTR to preserve highlights. I support this position.

The problem being that it can be difficult to estimate, at the time of shooting, which pixels are overexposed (especially with strong colors), or which ones have insufficient SNR.

The manufacturers, to facilitate this kind of advanced shooting, would have to provide methods to help us with this.
