How to Develop a Photo Using Blueprint Paper and Windex

Develop blueprint paper using Windex.

Step 1: Grab a Container

Order some take-out and rip the lid of the styrofoam container.

Step 2: Fill With Windex

Pour adequate amount of Windex glass cleaner into container lid.

Step 3: Rack

Find something that you can set your paper on so it doesn't get wet but still absorbs the Windex fumes.

Step 4: Plastic Bag

Place inside plastic bag so the fumes are contained.

Step 5: Grab a Print

Find a nice black and white photograph that you will use for the contact printing.

Step 6: Diazo Paper

You will need some blueprint diazo paper. I found mine on ebay for six dollars.

Step 7: Stack Them

Place the blueprint paper sensitive side up on a flat surface. Then place the black and white photo face down.

Step 8: Sandwich

Sandwich with a piece of clear glass.

Step 9: Expose

Place in DIRECT sunlight for 4 to 5 minutes.

Step 10: Check Paper

After you have exposed for 4 to 5 minutes you should see some discoloration that resembles your image.

Step 11: Develop

Place paper sensitive side down on the rack in plastic sack for 5 minutes or more. Make sure to close the plastic bag so the fumes stay in.

Step 12: Done

Enjoy your Windex print.
