That's excellent Don, especially when you see the price of
a commercial one A plywood box lined with polystyrene
or radiator reflection foil would work as well. I like
the cold fluorescents but be careful to make sure that they
cover most of the spectrum.

If you've got Apple Gear they have already recorded where you've been

Ask them nicely to Geotag your photos If they haven't already

#3 is my favorite. A pity that there was not more of the bend (centre-left) but what I really like is the timeless quality - apart from the baseball caps there is nothing to say this picture could not have been taken 40 years ago.
They had baseball caps 40 years ago!

I'm quite sure all photographic lenses quote focal lengths at infinity.
And even then they round up
Except when they round down! The Pentax A*300mm f/4 was measured by AP at 315mm (infinity). In practice at about 6m it gets in about 11% more than the other Pentax *300mm lenses.

I don't need the manuals Kim.... probably because I haven't got any of the cameras, but a big Thanks for providing the service if it's needed.

I started off with two new Black Spotmatics in the early 70's
