I also thought that Browne had used a Vest Pocket Kodak, until I bought an early model of this camera from 1912. When using it, you immediately notice and see that Browne must have used a different camera. A few reasons:
- The conservator of Browne's photos found an uncropped print of a
Titanic photo, and from this he deduced that the negative’s size has to be much larger than the negative that fits in the Vest Pocket Kodak.
- The
Titanic photos in Browne's famous
album are contact prints and have an aspect ratio that corresponds to 118 film (1.31:1) and not 127 film (1.54:1). A Vest Pocket Kodak uses 127 film.
- The Vest Pocket Kodak was introduced in April 1912. Assuming that stores had the brand-new camera in stock from Monday, April 1, 1912, Browne had only 8 days to purchase the camera before boarding. Not impossible but also not likely.
All in all, I think Browne used a quarter plate camera, such as the very popular No. 3 Folding Pocket Kodak that uses 118 film. The aforementioned conservator thinks so too. Check
The Titanic Commutator Issue 200.
If you are interested, I can tell you more about the differences in practical use of a Vest Pocket Kodak versus a No. 3 Folding Pocket Kodak and the significant difference in image quality between the small Vest Pocket Kodak and a No. 3 Folding Pocket Kodak.
