Canon EOS RP RAW editing flexibility?

Yeah this was an interesting point.

ISO 50 setting make a +1EV overexposure right?

In connection to ETTR. When you hint the right side of the Histogram this doesn't mean that it's the end.

This only means that this is the last point where the JPEG wouldn't blow out!

The RAW file can handle up to 2 EV overexposure, I read somewhere.

The reason I actually shot at some point wit ISO 50 on my EOS 6D Mark II was actually a EOS RP review I watched on YouTube, where the reviewer showed, that the ISO 50 setting had much less noise in the shadows that ISO 100!

Of course he didn't shoot a high dynamic range scene.

The result had been the same if he overexposed the ISO 100 RAW 1 stop while shooting and made the image darker afterwards.

Am I right?

But this is IMHO a good practice for ETTR:

The EOS RP can handle 1 EV overexposure with ease and it can bring back the according to the histogram overexposed  highlights in Lightroom without clipping.

So instead of trying to click 3 times on the exposure to match this +1EV I can remember I  just uses ISO 50 (the 6D Mark II has the same sensor as the EOS RP) and then made the exact ETTR on my histogram.

The results were not overblown afterwards.

I just forgot about this technique and didn't practice is on my RP for actually no reason... I just forgot ... maybe I had too much gear in the meantime ^^ Canon EOS R, Olympus, Sony, Fuji, Nikon... Oh my... ^^

But yeas I still use the RP an my main camera and please tell me if my thoughts are correct about the ISO 50 with the ETTR I did at some point or did I misunderstood this ISO 50 thing
