<p>[QUOTE=&quot;dougsmit, post: 1859929, member: 19463&quot;]It is never that easy.&nbsp; Auto exposure cameras try to make everything a medium gray and this works fine when the subject is made of various middle of the road tones.&nbsp; However when the background is tube blackened, the camera will lengthen the exposure in an attempt to bring detail where there is none.&nbsp; That is where you have to override it and tell it to nevermind the black and just expose for the subject.&nbsp;&nbsp; Some cameras allow you to set the exposure to be read only from the center but that has drawbacks as well so the best way is to take a picture and see whether you got what you want and repeat until you do.&nbsp; After a while you will learn what exposure works best because you are smarter than the program in the camera which never learns what is important in a photo and what is not.&nbsp; Some modern cameras are taught to look for a pattern of a face and set focus and exposure from that part.&nbsp; </p><p><br /></p><p>The next step is to learn to use postprocessing software which allows you to look at the coin and the photo and change things until they match.&nbsp; That is easier if you get as close as possible with the original exposure.[/QUOTE]</p><p><br /></p>
