Previsualizing a photograph as a Cyanotype -

Inverting the Positve Image in Photoshop to print the negative

When you paint any liquid emulsion on so it extends past the edge of the photographic image you create a very active visual shape. Consider that this not only frames the photographic image, it visually combines with the photograph and becomes an integral part, the whole image becomes the photograph and the boarder, it acts like a figure while the ground becomes the paper the emulsions sits on. . So when you are painting on the emulsion, consider the aesthetics of the total image.

While painting on the emulsion in an intuitive manner can produce fantastic results, you might like to carry out some experiments in photoshop or on paper to get an idea where and how to paint on the emulsion and how this edge will combine with the photograph.

1. Convert the image to B&W in photoshop.



2. When you click on this dialogue box you will get various options that allow you to change the tonal relationships of the elements in the image. In the case below the yellow filter has been selected, which is similar to placing a yellow filter over the lens when you took the photograph.


3. Once the image is converted to black and white copy the image - (on the key board hit - control A) and then paste it into a new file - (open a new file control N.) Make sure you select RGB in the color made or the image will stay as B&W.


4. You can then set the colour balance to simulate the process you are using, in this case a cyanotype Note the levels and the option to select shadows - midtones and highlights


5. use the eye dropper tool to select a suitable colour to fill the background

Switch the background foreground colour



6. Select image - canvas size



Select percentage

type in 150% or an appropriate % - you can match this to the size of the paper you are going to make the print on.
You will place a large boarder around the print that has the same colour as the area you selected with the ye dropper.


Make sure that you have white selected as the background colour.

Select the eraser Tool


You can change the size, diameter, hardness and nature of the brush to suit.

Use the eraser brush tool in photoshop erase away various areas. Look critically at how the areas of simulated emulsion at the edge relate to the image.

Here we see two areas where the emulsion has not been applied that connect with the lighter lines in the photographic element. This gestalt connect the two and draws the lines out to emphasis an make them longer.

Here we see how the coating extends the large dark area - because it becomes relatively larger in relationship to other areas of the print it becomes visually more dominant.
