Photoshop work on photographs

Hello, I am a photographer, I already know quite well how to use Photoshop CS3 but I need to improve my skills. I am looking for someone who is really good at working with photographs in Photoshop and who can give me lessons. We can do the lessons by Skype. To give you an example of the sort of things that I need, here are three examples of things that I want to learn. First, have a look at my portfolio, so that you can see the sort of things that I already know how to do : [login to view URL] EXAMPLE 1 : How was this done ? To start from this : [login to view URL] and get this result : [login to view URL] I am especially interested in the texture of the skin, and color adjustement. I know the standard Photoshop tools, but I cannot obtain this result. EXAMPLE 2 : How to get this sort of results : [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] EXAMPLE 3 : How to get this sort of results : [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] I can do any test photographs that would be needed to work on as examples during the lessons; or we can use some of my photographs that I already have of course. Can anyone teach me how to do these things and master Photoshop better ? The prince will of course depend on how many hours will be needed. Jiri Benovsky [login to view URL]
