Okay folks, just got out of the darkroom with the CC40Y installed. I placed it inside the bottom bellows of my Beseler so its sitting on top of the lens. I've done QA work before for software company so I can take out most of the variables. WITH the CC40Y filter, the same negative and time, the print looked about 1 - 1.5 stops LIGHTER. That was expected. I used a #3 filter. Usually I get pretty good prints with the type of processing I do. I've had this enlarger for about a year now but haven't been in there for more than....hmmm 40 hours the whole year.
So I increased my exposure time to about 1.5 stops and it was a little dark. So I backed down to 1/2 stop less thereby making the exposure 1 stop more than the original and did a little edge burning. That print looked just about the same exposure as the first BUT..... the contrast is WAYYYYYYYYY BETTER! So I figure, the filter will add at least 1 stop more exposure but not as much as 1.5 stops.
I was wondering if I lost my printing touch with this new enlarger. Seems that the darker areas needed more burning in than I was used to. I also couldn't get that right contrast like I do when I scan the negative and play around in it in GIMP. I always thought "why can't I get this same contrast when I actually print?" Everything else was the same processing-wise for years!
The bad part is...1 stop or 1.2 stops more than my usual is pretty long. And if I need to print a large print, whew! That's gonna be a loooong exposure time! Dang, I really may just bite the bullet and get a V54 bulb.
But wow, neatO experiment!
Thanks EVERYBUDDY!
