Adaptation: Ink Editing in Photoshop

For ideas for textures for adaptation project i have made some ink splotches, scanned into photoshop and edited and overlayed images to make some texture ideas.

6-7 were using the 'difference' layer, and the rest were done using 'screen' layer.

The shine from 1, 4 and 5 come from overlaying more than 2 ink images.
