I recently read this great article in Digital Camera World titled 7 ways to make precise selections in Photoshop. It goes into detail into these 7 techniques:
01 Quick Selection
02 Refine Edge
03 Channel selections
04 Color Range
05 Handy shortcuts
06 Marquee tool tips
07 Select Focus Area
Click here to access the article – definitely a keeper for me!
Best wishes in your photography adventures,
