Short update:

I just did it! My first selfmade print last night! Was fun and i am feeling kind of addicted now. Yay!

One thing puzzled me, and i think i am just not getting my head around the corner here: the test strip showed me, that a 4sec
exposure time gave me rich blacks, nice highlights. I think it was f16.

If i want to get a longer exposure time...let's say to do dodging and burning...i need to open the aperture more?
Because at a camera you would close the aperture to get a longer exposure time. But with paper it works the opposite..
