Ignore the dust. Ignore the fact it's not a great print even.
This is exciting because it's the first print I've made in about a year - this is proof that finally the new darkroom is, well, dark enough to print in... This is literally the third sheet of paper to go under the enlarger since moving house (the first two being test strips) so I'm very happy indeed :-).
A major cleaning & dust control exercise needs to follow though...
Congratulation too. Me too build, with my own hands, a little room on my house. My wife tell me that take more time that Noe's ark. But finally I do it. Now the problem was the time for take pictures and develop. I try to make it. You say don't develop for one year. I didn't for near twenty. But always was in my head return. As you say, the important is your new darkroom. Go on again. (Sorry my english isn't very good)
