Postrendering Slime in Photoshop
By Razorsharp 2003

Welcome to this specially commissioned tutorial in creating cum and slime in Photoshop!
Note that although this tutorial is for Photoshop 6, the basic technique is usable with most other paint programs as well as other versions of Photoshop.

These are the basic steps in my technique:
• Create a selection in the shape of the slime/goo/fluid
• Fill the selection with a color
• Edit the transparency to make it look more like a fluid
• Add highlights and shadows to it to give it a 3D look

Start Photoshop and open the picture you intend to edit.

This is the original rendering I did for this tutorial, and the finished picture with cum/slime added.

First of all, take a look at the picture in the Layers palette. The picture is in a single layer named Background and has a small icon of a padlock to the right. The padlock is there to signify that this image cannot be moved since it is the background. It also means that doing any editing on this layer will alter the original image.
Layers palette

Press CTRL+A to make a selection of everything in the picture and then CTRL+C to copy it. Pressing CTRL+V will paste the contents into a new layer. Do this to create a new layer, identical to the Background image. By default this new layer will be named Layer 1 (unless there are any other layers already in the image).
Hold down the ALT key and double click with the mouse on the Background layer. An edit box will appear where you can rename the layer. Another (less swift) way of doing this is to select "Layer properties" in the drop down Layer menu.
Naming layers is a very good idea, especially when working with a lot of layers. Give the layer the name "Backup". Now ALT-double-click on the next layer (Layer 1) and rename it "Main image".

Now select the "Backup"-layer again. In the layers palette, there's a row of icons to the right of the text "Lock". The last of these icons looks like an padlock. Click in the checkbox next to it. Now you have locked this layer. This ensures that we don't accidentally edit the graphics in this layer.

Worth mentioning is that if you try to paint or alter an locked layer, your cursor will turn into an forbidden-sign (a circle with an diagonal line in). So if you're wondering why the heck you can't paint all of a sudden, and why your cursor changes shape, then check to see that you've selected the right layer. It's a common mistake that can cause a headace if you don't know what to look out for. (Yes, I have done that mistake.)

The reason for creating a copy of the background image is backup - if I happen to do an alteration later on that I'm not happy with I can copy the graphics from this original layer to undo the alterations. Hopefully, it will seldomly be needed. But when you do need it, you'll be happy it's there.
