Cyanotype Printing

Yesterday I did some cyanotyping. A recent trip to see the purple martins roost at the old Highland Mall left me with some images that were just begging to be cyanotyped; high contrast stuff, silhouettes, and such. I also had some old negatives from past cyanotype printing that I wanted to print again.

I had a rough time getting going. As with previous times, I start out without enough exposure and take a while to settle in. All told I ended up with 8 keepers. I need to use test strips more :) I also realized the Canson 140lb paper that I am using is not the best suited for larger prints. Compared to some other types in my stash, it was flimsy when dry and very delicate during the washing process. I’ll be using it instead for watercolors or cutting it up into 5x7s for cyanotyping. It won’t fall apart so easily when cut to smaller sizes.

Some larger prints up to 11x15s. Forgive the warped edges from the not very flat drying. They haven’t been pressed yet.

When printing, I always keep coming back to this one image of the Alamo I took a few years back. The contrast works so well with the light raking over the rough cut limestone. I remember standing there in the hot sun waiting for a second or two when the tourists would clear; the State Trooper guard watching me from under a shade oak with a wry grin on his face. I stood there for about 15 minutes and got 3 or 4 good frames during two clear moments of a couple seconds each. Two hours of stanchion-cloning-outing later and I had my image. Totally worth it.

And some more Martins. I plan on doing a post of the whole final photo essay soon.

Watercolor Sketches Around Austin

Between my trip to Ireland and my trip to Costa Rica during July I managed to get out a few times and do some watercolor paintings around Austin.

Light Painting | RGB LED Wand First Run

Lately I have been working on a few arduino controlled light painting tools and recently took the first prototype out for a bit of painting in Austin.

A more detailed post about the wand will follow, but a bit of info for the curious. It consists of a 4 lead common cathode RGB LED strip controlled by an RBBB Arduino clone and “driven” with a uln2003 darlington array IC. 4 potentiometers make up a simple UI that controls the multiple mode selection, color and time values for the operational modes. This first version just had three modes programmed for this outing: solid color mixer, time controllable dashed color mixer, and time controllable rainbow fade. Runs on 12v.
