Used this overlay, that I got from a free texture site, but unfortunately, I don't have the link, as it was on a previous computer. I got the link off a DPC thread, so that shouldn't be too hard to find. ;P
I placed overlay over image, which was converted to B&W, and then added two solid colour filters, one blue, and one brown to pick up the tones in the overlay.
I played with the opacity and masks on each filter, to get the desired result.
I am also very new to using overlays. I got a taste for them in the Diptych challenge, and haven't used them since. So a big thanks to iamwoman for setting this challenge.
I took joynim's suggestion, and added a little grain.
Love the image, so fun! The overlay really adds dimension and interest. BTW, the overlay was created by Playingwithbrushes, you can get larger sizes here.
Oh, this is AWESOME! I copied your overlay, but I'm sure its a small version. I'll try to find the larger size later, but it looks REALLY cool. Its perfect for that photo. You sure don't look like an overlay newbie :) I look forward to seeing more over the month.
