Screen
Blending Mode
Photoshop has many different ways of blending
layers. Different blending modes determine how the pixels
on one layer effect the pixels on other layers beneath it.
The
Screen blending mode is available with all the other
blending modes on the layers window. Screen blending mode
brightens the underlying layers depending on how bright
the screened layer's pixels are. If the screened pixel is
black, it will look completely transparent. A white pixel
will be white.
A screened black layer can be used to add lens flares and
other bright things to a picture with the option to remove,
filter or fade them.
For Example
I've found a picture and created a new new layer above it.
Then filled the layer with black and added a lens flare.

Now
adding any filters to the lens flare
layer will only
effect the lens flare. There is now also the option later
on to
delete the lens flare layer or change it, offering
more flexibility to your photoshop files.
Conclusion
Different blending modes offer a different effect. Use the
one which stimulates your optic nerves in the best way.
