Hey Goldie, post some examples of what you're looking to achieve. There are lots of different ways to post a photo. It will help us maybe zone in on one as a starting point.
I use a few different techniques on my photos. Some will give you a painted look which is pretty if you want a painted kind of look. You need to learn about layers and layer masks to achieve most of the looks. I also use a photoshop plugin called Imaginomic to give me a varietyof skin finishes. There are some great photoshop books that specialize in teaching skin treatments. In general the Kelby books are the best. Start be exprimenting with the painbrush set on airbrush, soft, with low opacity and just practice. It takes a LOT of practice and experimentation to develope a style that is your signature. It doesn't come fast,so be patient. Good luck.
