I have an EOS400, and usually save my shots as jpeg and raw. With a typical photo, I use the histogram, and for the work I do on the photos I am comfortable with this (at the moment).
So I have been reading about flats and thought I should give it a go - I currently just do the darks. When I take the flats, there isn't anything in the histogram. Its really odd. There is just nothing there. In this article, mention is made of the average pixel value, so I thought I would look at that to see if I am on the right track.
Until the last month or two, I have used PaintShop Pro. But just before Christmas, I got CS3 and am still finding my way around.
