Gum print test strips

My attempt at controlling variables.

These are 15sec increments to 1:15.

All of them with .3g / 4ml gum/sensitizer ratio

I settled on 45 second exposures as they were in the middle of the range for each color.

When I printed the tri-color print I used .2g/.3g/.6g per 4ml for C/M/Y respectively. 

The last one is a cyanotype test
