1. Make a new document. Keep the background as white.
  2. Make sure the foreground color is black. Pick a brush and start brushing. I came up with this:
    First layer
  3. Make a new layer and change the foreground color to #333333. Get a new brush and start brushing. I came up with this (just more foggier):
    Second layer
  4. Make a new layer and change the foreground color to #666666. Get a new brush and start brushing. I came up with this (again, more fog):
    Third laery
  5. Make a new layer and change the foreground color to #999999. Get a new brush and start brushing. I came up with this (you think that's enough fog?):
    Fourth layer
    (Nah... :D)
  6. Make a new layer and change the foreground color to #FFFFFF. Get a new brush and start brushing. I came up with this (okay :D): Fifth layer
  7. Start messing around with the blending modes. I made the blending mode for layer 2 as: Multiply. And for layer 4 as: Overlay.
  8. Make a Color balance Adjustment Layer.

  9. Modify all: Shadows, Midtones, and Hightlights to your liking.
  10. Repeat steps 8 and 9. But for 9, try to focus on one or two points. I try to focus more on highlights and shadows on the 2nd time around.
  11. Mess with the blending modes. For the first Color Balance Adjustment Layer i used: Multiply. For the second one i used: Soft light.
  12. Add a Pattern Adjustment Layer.

    Choose black scanlines, 2 pixels apart. (If you dont have any black scanlines, refer to my simple tech layout tutorial).
  13. Change the Blending mode to Soft Light, and the Opacity to 30%.
  14. Add a Hue/Saturation Adjustment Layer.

  15. Choose a color similar to what you have so far, make sure "colorize" is checked. Apply it, then change the Blending mode to Multiply.
  16. Now make a selection on that layer diagonally across, I selected upper portion.
    Hue/saturation selection
  17. Right-click on selection, and choose: Feather: 20px, and press delete.
  18. Now, choose a nice matching render. Drag it in. Resize it till it looks good to you. Hold Shift when resizing to keep everything in proportion. Shift+Alt when resizing may also be useful.
  19. Put the render under one of the Adjustment layers till it matches the background.
  20. Make a selection around the render, where you think might add a nice blending with the background. I chose these areas:
    Render selection
    Then feather it: 20px.
  21. Right-click: Select inverse, and apply a layer mask. If need be, lower the opacity for the render. I lowered it down to 80%.
  22. Make a new layer. Select all (Ctrl+A). Edit > Stroke: 1px Black.
  23. Use the Magic Wand tool to make a selection inside the border. Then, Select > Modify > Contract: 1px. Then, Edit > Stroke: 1px Black.
  24. Add some text, apply some Blending Options, and we're done.
