Help with Photoshop CS6 multiplicity....aarrgghh!!

February 7th, 2013
I am hoping that someone can help me with photoshop CS6 and a multiplicity shot.
I have been following this tutorial http://www.youtube.com/watch?v=3spT03p0XAQ and all is fine until I get to the part at 3:08, where I am required to select a black brush and then erase myself out of the layer. I can't seem to get anything to happen here.

I can select the brush tool, but can't seem to find how I make it black and then how I erase myself. I am sure it is really simple for those who know how to use PS, but I am a complete novice, so if anyone could step me through this part, I would appreciate it. I am using a PC.
Thanks.

@stuckinoz The trick is that you are using the black brush on the layer mask -- this makes the parts of that layer that you paint with the black brush disappear (become masked), and lets the layer below show through.

To do this, you need to make sure you have selected the layer mask, by clicking on the white box in the layer panel (just to the right of the little chain symbol, and to the left of the name of the layer).

Once you've selected here, you can select the black colour. Select the brush tool, then at the bottom of the toolbar on the left, you can see the two colour boxes. The top left shows the foreground colour, which you'll be painting with. It's probably black by default, but if not, you can click on the little 'black and white' symbol just below the foreground colour box, and then the swap button just to the right of the foreground box.

As you paint on the image now, you'll see the contents of the layer below start to appear, and you'll also see the white box in the layer panel start to show black areas where you have painted.

Make sure you select the layer mask before you use the brush. Everything on the layer mask that is white will make your images connected to the mask visible, black lines on the mask will hide the corresponding parts of your image and everything in between will make your image partial transparent depending on the blackness and gradients of the tools you use in your mask.
The chap uses a soft brush in the end to make the image softly overflow the image below. You should be able to that by hiding the layers below.
You can see the colour of your brush at the bottom of the toolbox where you selected the brush. The front colour of the 2 squares is your active colour. Click it to change the colour but remember that, since you are working in a mask, all colours will be translated to a greyscale.

Succes
