Step 8 We’ll now use masks so as to apply the effect sparingly. Order the layers as shown (left). For the ‘Black Dots’ and ‘White Dots’ layers, select the area of the girl using the ‘Girl 2’ layer for reference (as detailed in Step 1) and select Layer > Layer Mask > Hide Selection. Now every time you want to make a part of the layer visible, you can paint over the mask to reveal it.

I recommend that you make a pixel selection of the dots before painting the masks as well. To do this, right-click with the mouse over the thumbnail of the layer with the halftone girl and hit Select Pixels.

Step 9 First make some white dots visible, then make some black dots visible, always painting over the mask. After that with the pixels selected, hide some areas of the girl’s photo again using masks.

Step 10 To complete the retro effects, I’m going to use a paper texture. The one I used can be found at Import the texture, place it at the bottom of the layer stack and label it ‘Texture 1’. With this layer selected, create a selection of the girl. It doesn’t need to be perfect. Go to Layer > Layer Mask > Reveal Selection, and make just the area you selected visible. Select the mask of this layer and go to Filter > Blur > Gaussian Blur. Use a radius of 50 pixels.
