This project was one of the projects the families worked on at our Instructables Build Night at the library in September. The kids looked for photos on the internet, created negatives and then printed them onto t-shirts or canvas bags.
The first step is selecting the image you wish to turn into a negative. Choose a photo you have taken or find one you wish to use and save the image to your computer so you can open it in the photo editor.
We used http://pixlr.com/editor to make the negatives for our project. In pixlr, choose "Open Image from computer" and select the photo you want to work on.
Once your image is open, choose "Adjustment" and then choose "Desaturate" to turn it into a black & white photo.
Next, choose "Adjustment" and then choose "Invert" to convert the image to a negative.
You are now ready to print your negative.
