A few moments might have accounted for some of these-Originally Posted by jim kitchen
1. the tilt within the tripod's head;
2. the center of gravity's projection shift as the camera shifts off center;
3. the transfer of any object's weight in a lateral direction;
4. the weight of any lens attached to the camera body;
5. any three dimensional center of gravity aberrations.
Dear jb7,A few moments might have accounted for some of these...
Dry subtle engineering humour...
I like that.

engineers should stick to driving trains
dry subtle carpenter humor
Feh. Not laughing.
Engineers make the modern tools used for carpentry. Without engineers, carpenters would be back to hand power only. I for one don't want a return to that particular past, although I recognize there's a subset of carpenters who do.
In case you don't know, engineers design and build the trains. The drivers ceased acting as engineers when steam trains were retired; modern trains don't require the driver to have engineering skills. Any more than an airline pilot needs engineering skills. Yet the label sticks -- because "we've always done it that way".

Calgary gets warm at times during the winter. Now Edmonton gets cold at the end of August [below 10ºC ] and stays that way until the beginning of June or July. That is cold.Dear David,
Yes, combined with a terrible frigging winter cold that I cannot give away to anyone...
Then again, you are enjoying summer, so you cannot receive it.

Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
I have a Mac so I cannot run you software. Model it in free space with x, y and z axes and you will be able to fully expand your model. Why not? Evidently you are too cold to photograph the Bow Bridge.

What's the difference between God and an Engineer?
God does not pretend to be an Engineer...
I told that joke at a API pipeline conference, and not one person laughed. Go figure...

Dear Steve,
It was developed with Excel 2008 on a Mac, so it should work...
Unfortunately, I am not too cold, but I do have a bad head cold that I cannot give away, although I want too, and I have tried to no avail. Good liquor does not work either...

I was given "How round is your circle" as a present today (www.howround.com), a generous appreciation of old-school nerdery. The first chapter is headed by this apposite quote:
"I have been obliged to confide the greater portion of the theoretical part of the present work to some mathematical assistents, whose algebra has, I fear, sometimes risen to a needless luxuriance, and in whose superfine speculations the engineer may perhaps discern the hand of a tyro."
J. Bourne, A Treatise on the Steam Engine...., 1846.
I didn't even make it that far and I'm an engineer with thousands of "Statics" problems like this one (now well) behind me.Did you say you got bored reading posts about tripods? No wonder, I got bored when not even 1/5 through this post...
I just hang my carry bag on the hook underneath my tripod with a bunch of (not currently in use) lenses from my overloaded backpack inside.
Beats looking for rocks and keeps everthing steady.

P.S. I never get cabin fever. Even at 60 years young the weather never keeps me indoors. Get out of the cabin, breathe the fresh air, hike off into the snowy hills, and take some beautiful winter photos............
All natural images are analog. But the retina converts them to digital on their way to the brain.
