We’re excited about a new workshop at George Eastman House in February: Digital Negative Making. For years we have taught a growing number of photographers how to make their own photographic negatives on glass using historic processes. Realizing that not everyone is interested in going that route, we decided to look into a new approach for the rest of the world: the “digital” negative.
But what is a digital negative? A digital negative is a negative image printed onto a transparency film using an inkjet printer. Once the original image is in your computer it can be edited “to taste” and prepared for lots of really interesting alternative photographic printing processes. The digital negative bridges the gap between 19th and 21st century photographic processes. You can use old glass plate or film negatives, that last bit of type 55 Polariod film you love so much, or even a digital capture from a smart phone.
Once you’ve decided on a printing process, like salted paper, platinum, or gum printing, a series of test prints are made to create a “printing curve.” This curve will be applied to the file before printing to help optimize the negative for the selected processes. The printing curve is a layer in Photoshop that has been adjusted for the specific paper printing process you’ve chosen. The curve allows the print to have smooth continuous mid tones while still keeping strong black tones and clean white tones. Once these tests are completed you never have to look back as the final steps are a check list of settings which once set, can be saved and applied the same way every time.
Here are some examples of Digital Negative Making in action:
Digital Negative Making is a technique that photographers could have only dreamed of in the past. Now we can easily combine the precision editing and tonal control of digital with the beauty and magic of alternative photographic printing processes. All this and more will be covered in our very first digital negative making workshop at the George Eastman House Museum next month. Sign up today! Hope to see you there!
