Gum Oil is pretty contrasty and gritty by nature. I admit to having been some what impatient to see the final product. So, Just one layer of oil color.:mrgreen::mrgreen::mrgreen:
One can get more tonality by etching less of the hardened gum off, then drying the print, adding more oil color to it and then etching again. As many times as the paper will allow. Or so I have read. So far I've done just the ones that you see here. But the day is young.
On this one I rubbed in the prussian blue, then etched it a tiny bit and then added the burnt sienna. The actual print is slightly warmerbecause of that.
I need bigger negatives. This 8.5 inch limitation is killing me!
