If you're in the unfortunate situation of having a great picture that you've only shot digitally, it's tough to make it into a negative so that you can print it on proper photo paper.|
Not everyone has a Lambda or Lightjet printer in the garage, even though you can now buy them used for less than the price of the garage itself.
In this case, this Inkjet film comes to the rescue. It's an 80 micron thick PET film, which is coated on one side to accept ink from an inkjet printer. You can create a large-format negative from your digital files, then make a contact print from it in the darkroom.
Ideal for creating contact-negatives for alternative processes.
