The three Mars photos below were taken during the opposition of July 1986. I used Kodak Tech pan film, exposures were (from right to left) 1/2 , 1 , and 1-1/2 second, with a 12 1/2 " reflector (Bowman Observatory, Greenwich.) In the bottom of all three photos you can see the polar ice cap.
Also, you can see dark and light markings on the surface. I believe planetary photography now belongs to the realm of CCD cameras, (which uses electronic chips as opposed to film) as good as Tech pan is, it can't compare to what these new cameras can do.
The mars photo below is a stack /merge of the center and left photos in the above photo. They were put together in a computer program called Paint Shop Pro5. This blends the data from both photos into one and makes for a smoother looking photo.
