Hi,
Finally, I've set my darkroom up(durst M300) and I have started printing my BW negatives.
I have noticed that my test strip does not match the final print.
Of course, I did not change any setting or paper from test strip to final print.
Also, I have seen that if I make a test strip switching ON/OFF every 5 seconds the enlarger, makes darker strip than leaving the enlarger always ON.
