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



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.
Ilford MG IV RC Pearl, 1 minute in Dektol. (but I've noticed this with fiber 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.

If your developing time is reasonably long, say one minute minimum, the difference is probably coming from exposure variation. Your line voltage may be varying. Does the electronic Graylab regulate the voltage or compensate for varyign brightness in some way? If not I would very suspicious of that.
