Thank you all for your responses, I apologize for any misunderstanding, I am not a beginner at this. My question dealt, I thought, with advanced color matching of two separate photo's. I have used match color many times. I have 2 books "Adobe Photoshop CS for Photographers" and "The Advanced Digital Photographers Workbook" - both indicate that the match color tool in Photoshop is somewhat inaccurate and that color matching can be accomplished with much better results doing it manually. I was basically asking for a procedure most likely using curves adjustment. I have in the past been laboriously adjusting levels,gamma,hue, saturation etc. with good results, however from my reading of these books I thought perhaps there was a better way. I have in the interim since I posted this thread, experimented with the match color tool and have found that if I mask just specific areas of similar color and texture, I can make minor adjustments with fade and get good enough results.
Thanks again

Chris
