Success! My first good print.

It would be interesting to see where dcy ends up in his lightsource lamp search. 25sec exposure time for a 5x7" print either indicates that the lightsource is weak or the negative is far too dense.

They do look dense (which isn't to say that the light source isn't weak; it feels weak).

Here's a comparison. The top roll was shot with my P17 for my film comparison test and I'm using it as a prototype for what a negative should look like. The bottom one was shot last year with my Olympus PEN is that I've been trying to print this week.
