[pure-silver] Re: Same Exposure Different Prints?

Dear Elias,
I had a similar problem some years ago. What had happened was that the cooling fan in my enlarger had slowed down somewhat.
The buld was not cooled enough and the wires from the bulb mount were soldered into a different socket. The solder melted over time and turned liquid. It did not drip off the wires but the no loose wires moved in the wind by the fan.
So I noticed small fluctuations in the image brightness. But it only started during longer printing sssions! When I would only priont gfor an hour so things were fine. It weas only during those long nights, that the heat ramped up and the problem appeared. 

Was a real bummer to find...

So perhaps yo should check some of the wiring...

Love
Snoopy

Hi All,

I'm exposing and then developing in D72 (Dektol) 2 H20 + 1 Stock.

I get prints that are just lightly different, like one will be perfect, the 
other's highlights are too bright.
Is time in the developer that critical? Sometime I have trouble grabbing the 
sheet and by the time I get it out and let it drip, it's been 5-10 seconds over 
before it hits the stop bath.

Should I not let it drip? Straight into the stop?

Or should I increase development time to minimize the differences.

prints before too)

Could it be that the dripping print maybe facing the safelight is more 
sensitive to the light?
I have not noticed any fogging on my prints (difference between border and 
image whites)

I suppose it could also be my timer or power source... but I don't really see 
how they could be off.
