How To Make A Vintage Style Double Image in Photoshop - New or Improved Skill Day 29

I wanted to make a soft, vintage style double image.

I placed my photo of some palm tree fronds in Photoshop
Command j to duplicate the layer
Image > Adjustments > Channel Mixer > Monochrome

Image > Adjustments > Variations
    Choose Midtones > More Yellow. OK. Save the image

I dragged my photo of a young man climbing a palm tree into Photoshop.
It was quite dark since his back was to the sun so I made a duplicate layer. Command j.
The Blend Mode for the new layer is Screen at 100% opacity. This lightens the image.

I cropped the image to be square.

New layer.
Place the palm tree photo and when happy with the placement click the check mark.
Blend Mode Multiply. 28% Opacity

New layer.
Choose a gold tone that will be used to fill the square. Edit  > Fill.
Blend Mode Multiply. Opacity 13%

Vignette
New layer.
Make sure the color selector for foreground /background colors is set for black and white.
If black is on top press Option Delete to fill the layer with black. If it's behind, press Command Delete to fill the space with black.
Make a circle with the Elliptical Marquee tool.  Feather set for 70 pixels.
Select > Inverse to choose the outer circle.
Click the Add a Layer Mask icon.
Blend Mode Soft Light. Opacity 75%.
