THOSE WACKY BLEND MODES!

I was thinking about who or how I could explain in logical or not so logical terms, the 25 blend modes in Photoshop.  They are frequently used when working at an advanced level of Photoshop and warrant some understanding to grasp how and when to put them in play.  Deke McClelland just posted this video that really does a wonderful job in explaining those frustrating but very necessary blend modes.  Enjoy!
