Query: Works Great-short comings yes but--

As a retired negative wedding photographer, I want spot-on results. But with the digital age I had trouble getting exposure/white balance correct. Yes, the processor could correct for my "slight" errors. I did not appreciate how important white balance was, nor that it can change as easy as exposure. After a couple of tests w/this card. I was amazed at the skin tones I got. I used a drug store type quality (Costco) for convenience & speed and got great exposures! Just think what a higher quality firm (i.e. Dale Labs) can do with my files!Photo correction programs: Just use the "eye-dropper" tool; get color corrections- presto!Short comings: The cards could be larger! The instructions could be more detailed- The makers of this product could benefit from comments here!
