I think the square root of -1 fits into this somewhere.

I think it comes as an add on option with Arsenal.

Thanks for the silliness!

For digital "reciprocity" try multiplying by the square root of
negative 1 or "i". Notice Pentax and Leica have no non-linear exposure curves!
Zero??? What is ONE divided by ZERO? Is TEN divided by ZERO bigger than ONE divided by ZERO?? Now the BIG question. How far is it from here to infinity? Think about it. Zero? Or Infinity?? How about the REAL answer. Twice the distance halfway back. That's IT Charlie Brown!!!!

On the serious side, after having shot digital exclusively for many years I had kind of forgotten a few
details about film photography. I was trying yet again to photograph a bell pepper (per Weston) with my 4x5" wooden field camera. Yikes, I had, I thought a 45 second exposure figuring in bellows extension, but had forgotten reciprocity for the B&W film I was using. Got massively under exposed. The actual corrected exposure should have been more like 2.75 or more minutes! Live, and re-learn. LOL

He's a naughty boy, got two pages out of it so far!!! Good shot.
In high school, (when we were still using slide rules on a regular basis -- some Pickett users even had a cool leather case so they could hang theirs on their belt) our math department had somehow acquired a very large, very expensive electro-mechanical calculator. In the classroom in which it was set up, the only convenient place to put it was on a counter very near the door. At least once per year, someone would have it divide by zero on their way out of the classroom at the end of class. The only solution was to unplug it and call a repairman to reset it internally. Maybe we need to be reset internally to accommodate the changes in the move to digital.

I remember doing something like that back around 1970. I divided something by something and got the thing counting up one number at a time. I think it went out to something like 12 places. After watching it for a while I was able to calculate that it would take several years to count up all the way. Don't remember how I got it reset, just too long ago.
Reciprocity failure is dealt with, in some detail, in the Wikipedia article entitled Reciprocity "(Photography)."

But if the number you are dividing by zero is also zero, then you can do it, and you can get a real number. It is a lot more fun to multiply zero by infinity.
Since 1/1 = 1, 2/2 = 1, 3/3 = 1 ... , so is 0 / 0 = 1 ?
All I wanna know: who one this debate?

Funny, I was researching this subject just the other day.
After reading several article on the subject, the conclusion is that digital cameras DO NOT exhibit reciprocity failure as film does, period.
Reciprocity failure was/is a film phenomenon, due to silver halide particles requiring a minimum amount of illumination to initiate the chemical change in them.
Here's one of the links I read...

Zero divided by anything is zero. But anything divided by zero is infinitely large. So you have to have more information before you can answer that question. It involves limits and derivatives. Kind of fun, really. But it requires more than algebra to figure it out.
