I believe that Adobe PhotoShop uses the facilities of the 64 bit
processors. Whether or not a program uses the dual core machines to
full advantage depends on both the architecture of the program, and the
setting, and design, of the compiler. Using multiple processors is not
a simple thing, and even if the program is compiled for optimal
multi-processor use, the OS must also support it well in order for
maximum benefit to be derived. For any given program design, there is a
point of diminishing returns when it comes to adding processors. At
some point, no further advantage in speed will be noted.

Actually image processing is one task which can easily be parallelised -
just split the image into parts and assign each part to one processor.
Or, if you are doing panoramics, assign one image of the set to each
processor.
