Cyanotype on anything
Not only did I make a cool print that I liked today but I developed a recipe to put Cyanotype on virtually anything. I'm a well accomplished individual. When I say developed I mean, I kind of think I'm currently the only one doing it exactly like this. I'm a lazy horse stemming from being an engineer so my method, I promise you, is for lazy leisurely alternative photography. I promise at Least you might make a print or two. OK Ego our of the way, let's share some stuff. This will be recipe AMO20250309
1)Apply this size to the surface:
1g gelatin,
1g gum arabic.
0.2g Sulfamic acid.
microwave for liek 9 seconds just to warm it up. Let it cool down before applying it...or not, you do you.
2)Following the Habib Saidane mixture ratios:
*1g 2% CMC (very thick substance).
*1ml water (or more to thin it down).
*0.25g sulfamic acid.
*1 dropper of mike wares New Cyanotype formula…a few drops Basically. More=darker darks.
Put this in the microwave for 12 to 15 seconds until it boils. If you do not do this, you'll never get it to mix, at least not that day. Let this cool down for sure or you'll ruin the bottom layer. Apply this only after the previous layer is dry.
I applied both using an air brush and the results are astounding. You can also achieve this by pouring both cold like a carbon tissue.
In my setup I exposed for 15 minutes but its probably more like 3 minutes in a UV lamp setup. To develop this, spray hydrogen peroxide 0.3% (not 3%). Wait 30 seconds. Then 1 wash in dilute acid for a few seconds. Sulfamic and HCL may make the blues brighter. Finally wash the yellow out in tap water in a few washes. This recipe doesn't frill and all the process happens in cold water, or warm water, you do you, the stuff is hard to dissolve unlike all the other recipes I've tried so far. Don't go too hot or it will start to dissolve the image. Don't wash too many times or it will start dissolving.
The original looks like this:
The sensitive layer retains really good details.
The trick is that sizing. I'm sure other sizing will work too but this recipe is not only simple but the stuff becomes sticky in water without actually dissolving right away. It survives temperatures around 45C.
On paper, do not use the gelatin+gum sizing, that soaks up the sensitizer and doesn't let it go. I instead used the CMC formula without pigment as a sizing. When dry I added the pigment version with a double shot of Mike Ware's new cyanotype. And it came out tremendously beautiful. I'm not sure if I'll be loosing the finish when it dries but wet it looked incredibly good. I developed by spraying 0.3% hydrogen peroxide and drunk ng it in 1 ml HCl + 600ml water pH ~2-3. Afterwards I washed it about 5 times in cold water to get all the yellow off. The blues are richer, there's more details in it but thankfully the formula clears to paper white. With the double shot and sizing I did notice a slightly blue tint...very faint... On the perimeter. Overall I was wowed yet again. You should definitely try it.
