I guess that Jayanand is saying that you haven't permanently changed your exposure decision. That is you can vary the exposure in the conversion. That is true, of course. But if you have completely clipped some highlights, (all three channels) they are permanently gone, irrespective of capture format. The factor that I want to manage best is that the sensor uses up to half of all of the possible tonal values to represent that first EV. So clearly, our original exposure decision can affect the tonal range we capture. Yes there are other factors, such as our sensitivity to brightness in the first place and the camera's compression methods etc. In practical terms it does sound like the permanent -EV may well be the best solution. Lots of people think so! But effectively cutting our sensitivity permanently is certainly a compromise. I am just interested in seeing just how much tonal range I can extract in different light conditions. Hey that sounds like trying to improve my technical skills along the way.
