Test: photo taken with Seneca Trio Wollensak Opt. CO. U.S.A.

[Petzval 1840]

Hi:

I give them this test of my Seneca Trio, to f:32 and with hard conditions of light (fluorescent lamp of warm color) to train with the process RAW.

The final score has been a fact for my companion Ferrán, from Manualens.com.

It seems to have a rotating waterhouse stop. Neat idea ... rather like the newly announced Canon with built in teleconverter sitting in a bulge on the barrel.

Hi:

The French lens of the photo is very small, of 70 mm of focal, but the photo was taken by the Seneca Trio.
