So, instead of typing everything about Chiaroscuro and Rembrandt Lighting out here...I am going to link this great easy to understand video on YouTube by "The Photoshop Mama". Take a look HERE if you are interested.
I am going to try to play around with this later this tomorrow and supply a before and after picture. I know that my before picture will be my 365. picture, since I was trying to go for that contrast between lights and darks. But with my next attempt I will try to add some Rembrandt Lighting!!!! Exciting stuff, I know...yes, huge dork!!!!
Before with little light under the eye to the left.
After with light under both eyes and shadow next to my nose.
