Hey everyone, I need your help with somethin'

A friend of mine recently gave me a cd with historical maps scanned to large scale jpegs of the area around me, their dated 1877!

Where I need your help is getting rid of the "old photo" look and make it appropriate for greyscale or B&W printing. I'm thinking of borrowing a plotter from work and printing to full size maps off.

Here's just a very small section of one of the maps, lets see what can be done

Here's my shot at it, but what I really want to get is as little printer ink wasted as possible. I don't to waste ink on places that appear shaded because of the faded photo look. The lake in this picture is a good example

Here are the steps I followed:


Desaturate the image.

Apply a Smart Blur. I used a radius of 8.6 and a threshold of 13.1.

Apply a levels adjustment to get the image very close to pure black and white.

Apply an unsharp mask.

Create a curves adjustment layer to turn all gray areas to white.

This will also make a lot of the black lines faint. So what you need to do is select it's layer mask and fill it with black so that it does not change the image, then use a white brush to apply the effect to the gray areas.


Good Luck
