some qualities

screen makes things brighter
multiply makes things darker

normal blend mode

default blend mode (usually)
keeping the picture on top of another picture

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
keeps the black and hides the white

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

screen blend mode

opposite of multiply
brightens
- black hides, white stays

using screen for brightening

create a levels adjustment layer
change the adjustment layer to screen
if the sky for example is too bright
1. open blending
2. go to underlying layer section
3. move the right slider to the left
  - split it apart using the OPT key
