RAW and EV setting posted on 30th of may, 2009

Underexposure or overexposure?

It all depends the purpose of the pictures. If you just want to have some photos from your holiday or from a party with some friends, one tends to shoot in JPEG i.s.o. RAW. In many cases you would select a (semi-)auto setting. And typically you want to give it some extra EV push for snowy conditions and some less EV for taking a picture of your black cat in a dark brown sofa. Just for the reason not to end up with a grey cat in a grey sofa as the camera tends to level everything back to grey :-)

But what with pictures that you want to sell or print in large formats? Well, in most cases you will shoot them in RAW to allow some good post processing. Do you still need to follow the standard rules from above? Nope. You can forget about your grey cat...

	I think the histogram is not a linear, but logarithmic. There are much more values in the lights area then in the blacks. This is the reason 8 bits images looks noisy in the blacks, but never in the lights. The value range from 1-255 seems to be a linear scala but is not.

	I totally agree with your article. In low light settings, I end up shooting at ISO 1600 and +1 EV and correcting exposure post processing instead of shooting at ISO 800 0 EV. The noise levels seem much better and I can still get acceptable shutter speeds. Here is my blog going over that.
