[OFF-TOPIC]
two bottles but did you
Henri Gaud only allows disposable styrofoam coffee cups for wine tasting, in order that the proper temperature is maintained throughout the whole session
I take the opportunity that we have and Oregonian citizen on-line : we should try to convince Henri Gaud to visit Oregon some day. He could combine some new photographic subjects for the tri-color process and at the same time enjoy some of the best Riesling wines of the New World.
Does the Columbia river gorge (or wherever Oregonian Riesling is made) still produce those excellent white wines I experienced 20 years ago ?
[NOW BACK TO THE TOPIC]
An alternative to true helicals is simply to allow a wooden box to slide inside another.
One should keep in mind the simple design rule:
The amount of travel of the whole lens, required to change focus from infinity to one metre (3") is equal to the square of the focal length in milliimetres, divided by 1000.
For examples with a 90 mm, the required travel is 90x90/1000 = i.e. about 8 mm (approx 5/16")
This is still within reach of a wooden sliding box.
For a 55 mm, things become tricky 55x55 / 1000 = about 3 mm (approx 1/8") ; there, you need an helical.
Good food, good wine, good company and good photography,
does life get any better?
Well done Henri,
c'est ginale.
