Expert Tom Bagshaw explains how to paint translucent shapes using Photoshop and create a ghost.
Creating ghostly shapes with a translucent effect can be a little daunting, but I use a simple technique that can be applied to a lot of things where you may need a translucent feel, such as ghosts, underwater creatures and plants, smoke, glass objects or even bubbles.
I use Photoshop CS2 but my method can be readily applied using later versions as well as Painter, because it makes use of vector shapes and simple layer masking. I think that as long as there's a light source and you can make a guess at where that light will affect a translucent object you're half-way there.
I use Photoshop’s Blur tool to soften the edges of the layer mask
I start by sketching the shape I want to appear translucent on a new layer. At this stage don’t worry about any details – just concentrate on the main shapes. On a layer above I use the Pen tool to create a vector shape.
With the shape selected, I create a Solid Fill layer, drop its opacity down to 90 per cent and add a layer mask to it. Now it's a relatively simple case of using a Soft brush with a low opacity to gently paint onto the layer mask with solid black in order to make areas see-through.
Finally, to get the most from the effect I concentrate my efforts on the surface form or more solid areas where more light is bouncing back, if you want the texture to be slightly 'milky'.
01. Shape it up
To get things started the basic shape of the ghost is added in as a Vector Fill layer with a suitable off-white colour. If you need to see your underlying figure sketch then you can obviously reduce the opacity further, but generally I drop it to 90 per cent so that the fill isn’t completely solid in any particular area.
02. Paint in character
After a layer mask has been added to the vector shape layer of my friendly looking ghost, I select a default Round Soft brush with the opacity pushed right down to 10 per cent. I then gently start painting black onto the off-white mask, effectively making the character more translucent.
03. Use the blur tool
I keep working up the form of my ethereal character by gently eroding the mask; the solid areas give the impression of reflected light. If you make a mistake then you can simply paint back over with white to repair the damage. Once you're done you can also use the Blur tool to soften your brush marks.
