Black and White 3D Image.

This is the original image that we will be turning in to black and white and then 3D.

To make the image black and white first, we selected 'Image', 'Adjustments' and then 'Desaturate'. 

This is the black and white image that we will now work with to make it 3D.

We make another identical layer to the other one and layer them on top of each other. 

To get the Levels up so as we can change the colour we go 'Image', 'Adjustments' and 'Levels' 

We can then change the Channel to Red and the Output Level to 0 and apply that to the image.

The same is done to the bottom layer apart from the Channel is Green and the Output Level is still 0, then apply that to the image.

We then select the top later and choose 'Screen' on the Layers tab.

We choose the move tool so as we can move the layer down and right to produce the 3D image.

This is the final image when the layers are moved and will make the feather stand out as 3D.
