Things for free:

When looking for free editing software for the scans of my sketches I came across Pixlr. Pixlr, like other free online photo editing software (Picnik, FotoFlexer, LunaPic) allows you to upload a photograph from your computer (some sites let you import photos from Facebook or Flickr, etc) and edit them. I decided to use this software because it was the most user friendly that I tested and allowed me to add color to my photos. For the sections of my graphic novel which are fantasy I've decided to add color (muted, but color nonetheless) to contrast with the grayscale of Simon's world.

These photos come from the 17th page of my graphic novel. I'll include one of Simon, which has no color, and two of Ruby (one with the original color, and another with the final muted effect). I used Pixlr to edit all of these photos and will continue to use Pixlr, perhaps adding photoshop effects at a later date:

 This is the first panel of page 17.

Here is the second panel. Originally I just added the colors that I thought were most fitting. However, after fiddling around with some of Pixlr's effects I found one I rather liked called "Old Photo":

I liked the way that this effect added color to the panel but didn't overpower it. I want there to be differentiation between reality and fiction in my piece but I don't want those lines to be so distinct. After all, Simon himself is struggling with those boundaries so that reader should feel them blurring ever so slightly as well.
