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

Hi Elias. To add to what others say about developing more fully and avoiding fog, I don't know what kind of enlarger light source you use, but if you are using some kind of cold light you can get variation in printing density due to the bulb getting a bit brighter when it gets warmer. I used to use an Arista cold light and if I wanted to make multiple prints off one neg, in a batch, I had to remember that after the first few prints they would start getting about 10 percent darker as I continued printing multiples. Now I use an Aristo VC cold light and in order for the printing time to be absolutely consistent I have to try to be certain the bulb is heated the same. So, before every print or test, now I turn my bulb on for 5 to 10 seconds and then quickly put the paper in and expose it. this bulb, as with my older Arista cold light, will sometimes go darker after I have made a few prints if I am printing a batch of the same. There is a gadget made by zone 6 that regulates the exposure by intensity as you print so that bulb brightness variations are theoretically eliminated.

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.

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.
