For today’s image, I picked a photo of a mural in downtown Fredericksburg.  If not for the modern bicycle and the clothing, it could have been an old postcard.   So that’s exactly what I chose to work toward in the post processing.   After adjusting and cropping the image to just the mural, I duplicated the original layer.  To this layer, I added the dark uneven border, shifted the colors to rich yet more traditional hues, added grain and then “washed out” the color just a bit.   I then duplicated this new layer and converted it to a lower contrast B&W and set the opacity at 65%.   I then used a soft brush eraser and randomly swirled away some of the layer to allow more of the color through.  I’ve included a copy captured after the cropping for comparison.
