Now, add a layer in between your two existing layers and add a splash of colour. To do this, simply add a gradient of your chosen colour to create a little contrast and use the hue command in the layer effects. Don’t make this too obvious, as the effect should be subtle.
Next, switch your image into Adobe Illustrator. With the image opened, begin to draw vector lines over the top. Remember to place it on a separate layer and lock it before you start, as accidentally moving the image as you draw your vectors is not good!
Draw whatever you fancy, and in keeping with your chosen image as this is where you stamp your mark on the piece.
If you have kept the original the same size in Illustrator, all you need to do is paste it into Photoshop and it will be the correct size.
If you’re not happy with the colour, you can simply adjust the hue by going into the Image>Adjustment>Hue and saturation menu.
Now highlight vectors using the Burn tool – using this will give added depth. You should vary the brush size to get the best possible result.
You want to make this appear as a cross between a real look and a plastic falseness to help it stand out from the original layer. This will obviously differ depending on what you used as a base image.
