Thank you Pete fro your feedback. I see what you are referringto, and I need to take a look at that. All three images were processed under the same conditions (i.e. white balance, contrast, et al). It is more prevalent in the first and third images 9as viewed on my laptop).
Than you Milan and Ivar for your comments and feedback - I plan on revisiting these image to see what I can do about the magenta cast in the wood tread.
