Hi all...
Making my first forays into the darkroom to print after scanning negs for the last year and a half...and it is fun!
Of course, it's a steep learning curve but so rewarding so far...
Here's my question...I'm using a dichroic color head and using Ilford's suggested dual-filtration. I test-printed an image at grade 3.5 and needed to go higher for a very flat neg. I bumped it up to 4.5, which is the highest grade on the chart.
I also doubled the exposure time from the previous print, as I've heard here and at APUG. I noticed on the paper info-sheet that the paper speed goes from 200 to 100 at grades 4 and up.
However, my print was totally black...hmmm! What happened?
I eventually got the correct exposure, but I'm puzzled...
I know that dual-filtration helps equalize exposure settings but thought that the dbl-time at 4 and 5 still held.
FYI...I was making 5x7 prints from 6x7 negs.
