The three color Gum Bichromate over Cyanotype I made today (featuring the lovely ofbovasso)! I posted the video above to explain some of my trial and errors from today because I thought it’d be too long of a post.. though it may also be too long of a video I’m not sure.

Some things I didn’t include:

• I’m using Pictorico Ultra Premium OHP Transparency Film
• Printing as horizontally flipped negatives on an HP Photosmart Home Printer (I’m using photo paper settings, 360 DPI, maximum DPI in print dialog and maximum ink volume)
• In Photoshop after separating the channels into CMY I changed in the levels dialog box the output levels to 50 on the left and 200 on the right to make it a flatter image
