Sorry, that link didn't work for me. But when you have something like that white wall in direct sunlight you have to ask yourself if it's important to keep detail in it. If it is important, then you also have to realize that the rest of the range you're going to get is very limited. Expose for the subject and don't worry about the rest of the frame. If you try and stretch the exposure higher and get more highlight you run the risk of noise in lower tonal areas which could ruin for instance a person's face which is in a bit of shade. As it's been shown so many places, the histogram is very important. Get that as far right as possible to get the best image. Know where your subject lies within that histgram though. That's a big part of reading histograms. You can put the histogram way past the right side wall and get what you want if your subject is in the centre. -- Jim Davis, Nature Photography http://jimdavis.oberro.com/ Standard Poodles for fun BMW motorcycle for pleasure * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
