At this point it was time to move onto preparing for the composite image. It was important at that point to have the face layer on screen to help gauge sizing. The next step was to use the oval selection tool.
Holding down Shift constrained the selection to a circle. Leaving the tool selected, it was then possible to move the selection around until I was happy with the result. At that point I created a new document and pasted in the disk. In readiness, I used the magic wand tool
with a tolerance of 150 to select the circle.
At this point it was time to apply the next filter, Flaming Pear's Melancholytron: Filters > Flaming Pear > Melancholytron. The following dialogue box appeared featuring the now changed disk.
The next few steps were definitely not in the user's guide. I had to hit the Prt Scr button on the keyboard to capture the image. Successive steps were: opening a new document and pasting in the screen grab; using the oval selection tool to copy the circular image; pasting that image into a new document.
Comparision: at left, the KPT Pixel f/x effect while the one on the right combines KPT Pixel f/x with Melancholytron. The final result is visually complex and atmospheric.
The final stage was to combine the two layers (head and background) in the same image. It was evident that the disk image was slightly too large for the head so, using Edit > Transform > Scale, I adjusted the size.
The following step was to apply the Layer effects to the background layer as had been done previously to the face: Layer > Effects > Bevel and Emboss
The final step was to desaturate the background layer in an attempt to make each layer distinctive - the gold on gold effect was too much.
To that end: Image > Adjust > Desaturate
A third layer has been added to the image - at this point, I saved and resaved/renamed the composite image. I could now flatten the image and output the file.
At some later point I might want output the final file with any number of background colours to suit a multitude of situations or use head or background individually. All those options were available provided I retained one of the layered files.
That's all, folks!
