Another Look at the Rust


After some pretty standard processing of the underlying photo of the concrete wall and rusted metal bolt and washers, I felt like it needed a little something extra. So I got the idea to blend the rusty door photo from the other day to, hopefully, make it look as though the concrete was rusting away to reveal the framework beneath.

Basically I:

  1. Placed the rusty door image into the concrete image.
  2. Went into the Channels Panel and made a duplicate of the channel with the most contrast – here it was the red.
  3. With the red channel copy selected I used Levels to increase it a little more.
  4. I then painted the center part (where the interesting rust was that I would have visible later) with black and the outer, door areas white to make a mask.
  5. Then I inverted the new channel and Ctrl-Clicked on the thumbnail to load the selection.
  6. I then went back to the Layers Panel and selected the rusty door layer and, with the selection still active, I added a layer mask.
  7. I changed the rusty door layer’s blend mode to Multiply to make it really feel like it was a part of the concrete.
  8. I also matched the color of the concrete image with the rusty door to make it look a little more realistic.

Hope you enjoy this one!

*A Brief Program Note: Given the busyness of the weekend and the Thanksgiving holiday here in the US, the P&P Weekly will be taking a break until next week.
