Would it be better with PS4?
Working on your response. I can see what to do, but not sure I could ever hand it over to edit / update to the professional photographer who has commissioned it. I'm writing a "cookbook" with specific keystroke by keystroke instructions for him, but this might be a step too far.
So since Friday is last day for cheap upgrade price, can you tell me ... would this be easier with PS4 (ie gallery image links directly to the Product Detail page of the image being viewed). If answer is "yes", then a brief note on "how it is easier" would help push me to buy.
