Wow! Thanks! Can you get a tri-colour densitometer onto it at some point, if at all possible?
Cheers,

I think they did that. I got the formula from a link found on largeformatphotography. There was a lengthy technical discussion that i did not understand at all about how they got it accurate. here is a link

This thread has given a whole new meaning to ''anally retentive''.
A moistened finger held aloft, a squint at the sky and a quick compute of the ' sunny 16 ' thingy is surely all that's needed to get a good exposure.
Gray cards and meters are for wimps and pussies... (!)

Isn't it time for another drwaing? On the next one Peter should have some billy goats with cameras around their necks, crossing a grey bridge, beneath which is a troll.

This is the point, really. B+W photography is enormously flexible, and astonishingly easy. IF you're going to start being 'scientific' -- beyond., perhaps, using a meter sometimes -- them do it properly: don't go for half-understood pseudo-science and empty totemism (such as most people's understanding of the Zone System and 18% grey cards).
There is real (if disputable) science behind ISO speeds and the design of exposure meters. Either embrace the science (preferably while admitting that it's mostly irrelevant unless you're a film manufacturer, developer designer, or highly technical reviewer) or admit that you don't actually know or care what you're talking about.

Fascinating! Thanks!
I still can't see why anyone would bother, but I commend your persistence in finding out.

An old Royal Navy insult is, "Don't just sit there with your thumb in your bum and your mind in neutral."

Roger now that you are teaching me that middle gray is not that important in practice, I have a question. I found a full gallon of light blue paint in my storage area in the garage. I dont remember what I bought it for. Its proably 5 years old maybe. Anyway, my question is. Is there any problem to paint my darkroom (read bathroom) light blue. I wont ever do color in there only b&w. The enlarger is in a separate dedicated area designated dry only. It is not in the bathroom. I already painted the enlarger area flat black.

I've heard that the Royal Navy has some strange - some would say unhygenic - habits and is prone to utter pithy epithets.
Sound lads, though, despite all that...

Something like that, but then, maybe not so much in amateur photography but certainly in commercial art, design and reprographics accurate reproduction of colour is pretty important ... speaking as a design director with twenty years experience I paid some attention to it in that time, I realise it's all perceptive but sometimes in the commercial world it is necessary to limit human error as far as possible which is what the OP is trying to do I feel

No harm at all, except that it will look much darker under red light. I'd go for white myself.

I hope you manage to keep your underwear dry and have a happy new year with your photography, with or without 18% grey paint... (!)

Ok Roger if im facing the trays, would it be better to have the wall behind me white and the wall in front light blue or vise versa? I may only have enough white for half the room. The ceiling is white, and the floor is off white vinyl. The tub is bright white. If I have to use some light blue where is the best place for it?

Hard question. If the safe light is safe, you want maximum illumination on the trays, so I'd go for the wall in front of you white. If it's not safe, the wall in front will absorb the unsafe light. Really, how much does more white paint cost?
Quite honestly, most safelight recommendations are VERY conservative. Frances prefers red safelights (yes, there are obvious jokes about her preferring to work under a red light...) and last time we did a serious safelight test there was no fogging at half an hour and eighteen inches distance.
