Maybe a good approach would be to add 10 seconds to the time, and use that time to position the tool, while blocking the light with the other hand or cardboard. Count off 10 beeps from the timer, then expose away.

Speaking of fires, a mile from here, there's a development along a ridgeline of a mountain. I'm sure they have a great view. But pointing to that, a fireman told me, "that's a disaster waiting to happen." Around here, you don't want to be downwind (west) of brush.

Back in the 1970's when I bought a house in Beverly Glen the brush came up to the patio, like a jungle. I paid a local guy to clear it back fifteen feet right away. Every year I would have him extend the cleared range and after about fifteen years I had it cleared to the ridge line. After the first five years, one by one the neighbors started extending their clearing and finally we had our small canyon cleared of brush. The Fair Plan insurance costs first for me and then for my neighbors dropped as the clearing extended and even those people who had the fire department clear their brush at large cost started clearing the brush themselves. In the over fifty years since that area which was burned by the 1961 fire, has not had even a small fire breakout or spread through it.

If you have the correct colour balance using magenta and yellow, dialing in cyan as a neutral density filter WILL without doubt send you colour balance way off tangent. With subtractive printing you cannot just alter one filter to use the effect as a neutral density .

Yes, dial in the cyan and an equal number of cc units in yellow and magenta of course.

The presumption is that all three filter sets (CMY) are still in equally good condition, and that any remaining white light spillover is negligible. That's probably not going to be exactly the case, but is likely to be close enough so that just a little re-tweaking for precise color balance is still needed. No big deal. I'd do a test strip regardless. But when doing the same kind of ND operation using my true narrow-band RGB colorheads with feedback circuitry, it's spot on, since there is no residual white light spillover at all.

But for sake of convenience, many colorheads have a built-in lower intensity option, basically an internal attenuating scrim operated by level.
