Week 9

So this week we had to do a few gum tests like the ones we did in class last week. This is part of the demo that we had in class…

Cyanotype (12mins) gum no pigment (25mins) on Canson Mix Media paper

These actually looked okay, but i realized I wasn’t a big fan of the Gum process. It gives too much of a soft quality, and I am not sure I appreciate that too much. But this was only the first example, so I am not yet at the point of giving up. I did notice a problem though, as I didn’t pre soak the paper before printing my cyanotype, the paper shrunk, and the negative didn’t quite stay in place of the Gum print. I am guessing this Canson Mix media paper, like all others needs sizing before anything is done to them.

For this week, I decided to experiment with gum with pigment and try out another paper that i found Strathmore Toned Tan.

Strathmore Toned Tan and Canson Mix Media (back of paper)

I tried both the papers and I wasn’t happy with either of them. But another issue that presented itself was the amount of pigment I had been using. Way too much is what it is. I used a 1/2" of watercolor pigments and clearly that was too much, but now I know. I will decrease that probably to 1/4" or even less for the Lamp Black. Also, the Cadmium red and the Green are just terrible.

As I did not like these gum prints at all, I printed some fun things just to keep exploring the Van Dyke Brown and Cyanotypes in different scales and papers. Also I wanted to print some of the images I took at the Di Rosa Preserve.

I really like the blue tones that the Canson mix media paper has with the cyanotype process, but I would like to try the back of the paper which has less texture on it.

I wanted to try the Vellum paper too just because I like the idea of being able to shine light behind it and the semi-transparent effect it has, but I am not sure this particular image worked for this.
