This means that if you under expose by a stop half the possible values are lost. With the M8 the values aren't assigned in a linear value. More of them are assigned to the shadows than the highlights, so when you underexpose with an M8 you aren't throwing away as many of the values, so it doesn't have the same effect as it does with a linear RAW file. I'm sure someone will correct me if this is incorrect <grin> Steve On 12/9/07 01:47, "Tina Manley" <images@comporium.net> wrote: > At 07:07 PM 9/11/2007, you wrote: >> So, when shooting the M8, err on the side of underexposure; if >> the historgram starts at 125 and goes to the left you still can have an >> outstanding image. > > But have you tried it the other way?
