To make a Platinum Print (or any other alternative print for that matter) we need a monochrome negative the same size as the finished print.

These days, the majority of our clients use digital cameras to capture their images which are of course colour by default. As we need a black & white image to make the negative from, I thought I would mention the method I use for making the conversion.

I know there are many ways of doing this and I”m not saying my way is the definitive way, but it gives me results that I like and that print well in Platinum and Palladium. Although I describe it as “my way” it was in fact taught to me by my friend and colleague Jack Lowe.

It is a method of blending 2 hue/saturation layers in Photoshop. I’m not going to outline it in detail here because Jack has done just that on his Digital Basics website. So I would urge you to pay it a visit where there is also a lot more information on digital photography matters.

What I will show you though is the result of this method on an image I shot recently.

As most of you will know, contact printing is the only way a Platinum print can be made. It isn”t possible to use an enlarger as in Silver Gelatin printing. This means that a negative the same size as the finished print is required. This is then held against the sensitized paper in a printing frame and exposed to ultra violet light before being processed. There are a number ways to obtain a negative large enough for your print. You could shoot on a large format camera and print from the negative produced. You could shoot on a smaller format and have an inter neg made at the size required. Or, particularly if you shoot digitally, it is now possible to have a high quality large format negative made from your digital file. All our digital negatives are made for us by Jack Lowe with whom we have worked for years now. So here is a digital negative, produced by Jack.

So why is it green? I’ll hand you over to Jack to answer that. “Well, this is the beauty of Hewlett Packard”s process; researchers and engineers on the project have found the green channel on the DJz3200 to act as the perfect UV cut for making Alternative Process Digital Negatives, hence their green appearance.” Here is the finished Platinum/Palladium print.
