Photo Line Drawing in PhotoShop

Open up the picture in PhotoShop and double click on the background layer to make it a normal layer. Then duplicate the layer twice so you have 3 layers that are all the same.

Select the top layer and change the blending mode of the layer to Colour Dodge from the layers styles drop down list.

Then Invert the image by going to Image and then Adjustments. For the Mac, the shortcut is Command+I. On the PC (which is what I am more used to), it is Ctrl+I. The picture may white out at this point.

Then go to Filter, then Blur and then Gaussian Blur. The amount of blur you use depends on the picture you are using and the resolution. I used 8.0 for mine.

Now select a Hue/Adjustment Layer and desaturate the image. Take the saturation slider to -100 and this will remove the colour information. Note: Don't go to Images, Adjustments and desaturate from there. When I did it, it made the picture a very funny colour and didn't remove the colour at all. Instead, on the Layers list, go to the icon which looks like half moon.

Then print it out and colour it in! For my picture, I used pastels.

Merge the scan with your original unedited photograph in PhotoShop to create mixed media reults. Open the original picture and the coloured scan, then drag the scan into the original document. Select Overlay from the layer blending mode to superimpose the coloured scan over the original picture.
