I'm really really sorry for the double post, but I have gone back and done things again many times and I just can't get it right. Maybe RobA can help me. After I first made everything bluish (with the Colors->Map->Gradient Map command), when I do the Seashore Layer my landmass continues bluish and not white like in the tutorial pictures. I admit I don't know if this has been asked before or not, but this is a thread with 50+ pages, so I simply don't think it is practical for me to have to read all of it (if this is the forum rules I will, but under protest). Please help me!!!
Edit: One more thing, whenever the tutorial asks us to create a new layer, is it a transparency layer?
