Hello,
I produced some tutorials last fall for a workshop I presented at AIC2012. These tutorials cover the basics to the advanced methods of creating and refining masks in Photoshop to selectively enhance your images.
I thought this would be a fitting place to share this 8 chapter series for my good friends here at ICEinSpace. For those who are interesting in learning about or expanding your masking skills I promise that these masking methods will benefit your image processing for years to come.
As always I freely share what I learn in the hopes that there will be some who benifit and enjoy this hobby even more.

Of course I make no claim that these are the best methods, but only some of the ones that help me.
Kindest Regards,
