 *** when is normal not default?
 - when you create a group the default is "pass through"
 - to apply all group filters to within the group change it to 'normal'
+
+** multiply blend mode
+ - multiply darkens
+ - ignores white
+ - multiplies dark onto image
+
+*** technique 1
+- duplicate an image
+- set it to multiply
+- change blending option
+  - take away from the dark
+  - find current layer slider
+  - hold OPTION key, click on slider to break it apart
+
+- problem is that if you change the underlying image, you have to change the multiply image
+
+*** technique 2
+- find an adjustment layer that changes nothing by default
+- set it to multiple
+- it effectively acts as a duplicate image
