But When used in the other mode, the "variable mode" (as the way I sometimes make my contact sheets) one bulb stays on full blast while the other variates. I have made almost no prints this single exposure one filter method with this head as I had switched to "consecutive filtration" my name for "split printing" (which to me sounds too much like split toning) before I even got this new wonderfull head. I started out switching first Ilford 5 and 0 filters. Then i got the special 40 dollars each green and blue filters which didn't make much of a difference. Now I flip a toggle switch on my Aristo 4500 head and the bulbs take turns. But as far as speed matching goes that is a big variable. When you get your high area's exposed right are you then able to adjust contrast to make for better or worse blacks while the high areas stay the same? I call that "matched" grades although I've heard of it working the other way around. It's idea t get a pivot point for density while your contrast would not change that. I gave up on that. With the two exposure "consecutive filtration" system you don't' need a pivot point, you don't need "matched" contrast filters. You adjust the green till your whites are right, your blue till the blacks are right. No starting from scratch when it turns out your contrast guess was wrong. Or dodging and burning like crazy to make up for the fact that you've picked way too high of a contrast. Sorry I can't be more succinct. Mark Rabiner
