Dark and Light Gif meme tutorial

Gif your scene to begin. For dark scenes it is obviously smarter to use a scene with a darker background and same goes for lights.

DARK:

1) Since my scene is darker, I duplicated my smart filter layer twice and changed the layer modes to 'Screen' (if you aren't using the smart filter trick then just use the Brightness/Contrast adjustment and adjust the Brightness to your liking)

2) I did some simple coloring on this gif:
Brightness/Contrast
brightness: 0
contrast: 80

Selective Color
reds: -19, -26, -56, -14

3) Since this gif has minimal movement, I just made a selection of the person with the Polygon Lasso Tool. Once you have your selection, inverse it (shift + ctrl + I or Select > Inverse).

4) Once you have your inverted selection, create a new layer and fill the layer with black. Guassian blur the layer (I used 2.4 pixels).

5) To make it look more natural I used a Brightness/Contrast adjustment layer and changed the contrast to 98, but it may be different for your gif or your gif might not need it.

2) I did a bit more coloring for this gif
Color Balance
midtones: -100, 0, 100
Change the layer mode to 'Soft Light'

3) Instead of making a selection with the Polygon Lasso Tool, I used a soft brush (around 85px) and filled in a blank layer with white (avoiding the subject of the gif) because this gif had more movement.
