End Result:
Version One:
Open the image you would like to work on. Double Click on Base Layer
to unlock. Dublicate Baselayer.
Use Filter >Blue > Gaussion Blue > Setting at 4.9 (you can play
with the setting). Image will appear like this:
Blend Top Layer with Base Layer. Use Blend "Overlay". The result will look like this.
You can Dublicate this Layer as often as you want. If the image becomes to dark for you, then you can also set one or more layer blends to "Screen".
To filter out the red tint, I added an "Adjustment Layer".
Layer > New Adjustment Layer > Color Balance
