Did you watch the smooth tones video I posted ? I'd like to know how he arrived at leaving the discriminated top half of the window ? I know smooth blends target tones together but they can't if they are discriminated out. Is there a possibility of missing masked coins amongst the primary discriminated targets ? I need to catch a good weekend weather break so I can compare both patterns to see. Page 97 of the CTX handbook is the pattern I use. I've since boxed in the Bottom right corner a tier higher to knock down on the iron contrast. I've so much to learn.
