Turn any photo into a dot grid artwork with these Photoshop actions. You'll get great results with dots that change size. They get larger in brighter areas and smaller in darker areas. Free download available.
To make the lights of picture brighter and more visible, I use Dodge Tool. To do it in non-destructive way, make a new layer, set to Overlay 100% and fill with 50% gray:
Take Dodge Tool with Highlights Range and Exposure from 20 to 80% to brighten the lights, burning effect. Vary brush size and Exposure, and you can see how I applied this tool on the pic with Normal mode ( there are some parts that are brighter - bigger Exposure and another less:)
To change color of picture, I use some adjustment layers. Go to Layer-New adjustment layer-Gradient Map:
Set this Gradient Map layer to Soft light 100%.
Layer-New Fill Layer-Solid Color:
Put this Color Fill layer to Color 20%.
To make picture get more contrasted, especially the light, I use a Levels layer. Go to Layer-New adjustment layers-Levels:
In final step, I use Gradient again. Make a new layer and take Radiant Gradient as we did in step 21. Change the mode of this layer to Soft light 80%:
Add layer mask and use brush with opacity and flow 100% to erase the man and about 30-40% to blur some parts as shown below:
