Darlot Artist Anachrom Pulligny and Puyo Lens Questions

[Jimmy Mathis]

I thought I would pass this article from "The British Journal of Photography, Volume 53, March 9, 1906", starts on page 184 - 189. It does talk about how to use the lens, so far this is the only writings on the use I have found........ and its in English not French, thankfully!

For those who care... enjoy!

Thank you, Jimmy!

Lots of interesting links in Google books, but all I get is 1/2 sentences!

I think Jim's comments about adjusting to the distance scale, based on his own experiences, seems very logical.

But there still remains the use of the aperture scale which fills one side of the WHS cut out. At least, I think it is an aperture scale. On my trousse set it runs from 3.5 to 5.5 (cm - diameter of WHS?). Although it has uniform scaling (that is, there are divisions of multiples of 10) it is obviously a log scale. 3.5 to 4.0 has 10 units, whilst 5.0 to 5.5 has 30 units.

Because the trousse set has lots of focal lengths available, there must have been a table supplied with the set which gave the relationship between the aperture diameters and their effective F values for the various combinations.

What would be helpful is to find a different trousse size with similar (but different?) F centimeter markings. Mine is the 40cm focal length set.
I don't have the original casket box, but Darlot often had a concealed compartment in the lid for the flange and/or exposure tables.

Steven,

Andrew from Sydney, Australia, who's has commented in this thread has some interesting Pulligny and Puyo lens, he may have one like yours, none the less his assortment sound very interesting. I hope he may elaborate in this thread on his lenses, Thanks Andrew!!!!:roll eyes:

Cheers

At last I have a new card reader for my ipad. So here is a reasonable photo of the F scale on the WHS cutout of a 40cm Trousse.

Jimmy Mathis, could you somehow post the 5 pages you're talking about here ? Google books is kind of restrictive towards us europeans it seems...

[Jimmy Mathis]

I found articles on the usage of the Pulligny and Puyo Lenses. When I find more info I will post.

There was a lot of confusion in 1906, too! The two descriptions of use seem to have little relation to each other.

They are both trying to describe the 4 lens set O d'A. This is the post-Darlot era.
