For the basic color treatment:
-Fill a new layer with the tan background color.
-Put your photo on top of that layer.
-Boost the contrast of your photo with a levels or curves effect, crushing the blacks and blowing out the highlights.
-Set your photo layer’s blending mode to “multiply”.
-Add a black and white effect to the photo layer, tinting it to taste for a sepia tone.
For the chromatic aberration around the edges of the photo (color splitting):
-Merge your layers into one
-Duplicate the resulting layer twice, so there are three instances
-Starting with the bottom, go into the Channel Mixer effect. Go to the green and blue dropdowns and change those values, which will say “100”, to 0.
-Apply a channel mixer to the middle layer, except this time turn the red and blue to 0.
-Add a channel mixer to the top layer, this time with the red and green to 0.
-Change the top two layers’ blend modes to “lighten”. It should now look like your original image again.
-Add a “Spherize” filter to the top two layers with a small positive value. Say, 5 and 8.
Done!
