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.
On a new layer, darken the left, right and bottom edges of the image using gradient preset "Foreground to Transparent" with black foreground color, as in image below. Decrease layer opacity to 90%.
Add to the bottom of the image a little green color. Everything remains the same, just use foreground color - #b3ed87. Draw a gradient from the bottom up to a little less than the middle of the image. Change Blending Mode to "Overlay". I highly recommend you hide layers with a background in one group that in future they do not interfere you (select layer and click on folder icon on Layer panel or Cmd/Ctrl + G).
And now proceed to a very interesting part. I'll introduce you to the basics of retouching. First, add a model into working document. Do to File > Place and select image "Days_go_by_III_by_almudena_stock". Use the Free Transform tool (Ctrl/Cmd+T or Edit > Free Transform) to resize and rotate model like shown in the image below.
Use Pen Tool (P) to circle the model and then get a round selection. Using other tools in this case, may damage model. That the curve is not bent after the previous bend, hold Opt/Alt and click on active anchor point. When you create model path, make from it selection by clicking button "Make Selection" on the Properties pane. Set Feather Radius: 0px. When you make selection need to remove the background from hair. For this we use option "Refine Edge" (Cmd/Ctrl + Opt/Alt + R or go to Select > Refine Edge).
In Refine Edge set View "On White" and Shift Edge: -40%. I not changed the contour, your job is to just take the brush out of the window and carefully paint the model's hair to remove the remains of the background. Click OK to apply the settings. Add a layer Mask for this layer to remove background (use "Add Layer Mask" button in the layers panel or Layer > Layer Mask > Reveal Selection).
And now proceed to retouch. First, make a copy (Cmd/Ctrl + J or Layer > Duplicate layer...) of the model layer (just in case you do not get the next steps. Delete it if not use) and rasterize it (right click on layer > Rasterize Layer).
