>>4453219That's exposing for the highlights, only relevant if the highlights are important. ETTR is about preserving shadows. ETTR is only useful if the scene's DR is smaller than your recording medium's, and even then the benefit is not without tradeoffs. For dark scenes on certain older sensors, ETTR might well work better as you raise the ISO. That's in the domain of low light photography.
>>4453220>ISO is brightness, not exposure. The point of ETTR is to increase the actual exposure, not simply brightness.True enough. You have a picture to take and open up the diaphragm or let the shutter stay open for longer. Yet sometimes you benefit from raising the ISO and then doing that. Rivers of words have been written about it, notably by Emil Martinec and Guillermo Lujik.
>If you consistently ETTR, you will consistently have the same colors.I don't think anyone argued otherwise, the point is those colors are often worse than the ones with a balanced exposure.
>>4453221If your sensor is basically isoless then ETTR is moot at high ISOs. If it's like older Canons then you clean up the picture raising the ISO up to certain values and staying within native ones.
