Albumen printing is tricky, but pays off once you get it down.
Today, I was having issues with sensitizing the Albumen paper. I wanted to check the difference between the single coated and double coated paper that I made a coupe of weeks ago. I'm going to be floating a bunch this weekend and wanted to make sure that the double coated paper was worth the effort (it is!).
I used a Hake brush to sensitize (brushed the silver nitrate on the Albumen paper) and got some "measles" on one of the prints and "weakness" in areas of the other print. Tomorrow, I'm going to use the 3 minute float on the AGNO3 - it's much better.
So far, my German Albumen paper is "da bomb"! The final images on Albumen paper will be much better than these, but I wanted to show you the process - as you can see, it's not for pussies.
Checking the print in the contact frame. You can see I have some "brush strokes" there - weak silver from a previous batch in the brush - and my technique wasn't perfect either. Just some quick prints for testing. 
Here, you can see those "measles" - other than that, it's okay. Keep in mind, these are "in camera" negatives, or foundation negatives, they have not been intensified or re-developed (yet). That's my next step - I'll compare Albumen prints - before and after.
This negative was a bit more dense (maybe 1.75) You can see the "silver issue" in the bottom right. Both of these images are gold toned.
