B&W Battle: Silberra vs. Streetpan
If you somehow missed the big news late last year, Silberra launched a ginormous crowdfunding campaign on Indiegogo to mass produce a brand spanking new lineup of black and white films. Now the fruits of everyone’s labor have slowly trickled down and the films are finally rolling (pun intended) out to the public. Us here at JCH HQ have been itching to get our little trigger fingers on the shutter button to test them out, especially Streetpan’s new rival in the ring Silberra U400. If you’re curious to see how this latest newcomer to the game fares, scroll on down and see for yourself.

This was the setup used for the test shootout. The lens I went with was the legendary Zeiss Planar 45/2; one paired with the Contax G2 and the other one, converted to M-mount by Miyazaki san, with a Leica MP6. Silberra U400 was loaded into the G2 while Streetpan was loaded in the MP6. Compared images were shot at the same exposure, both films developed in Fuji Minidol and scanned on a Plustek OpticFilm 8200i.

The Images

First thing you’ll notice when you get your negs is how amazingly thin it is. Streetpan is already quite thin but Silberra U400 is straight up anorexic. This image has zero ability to represent the thin papery feel of the negatives but does show the translucency compared to Streetpan. Being so thin too makes it curl a lot less.
*Note- on a related note Silberra issued this precaution that I wasn’t aware of till after the fact:
Loading the film into the camera shall be conducted under subdued light only (otherwise the first frame may appear to be overexposed due to extra thin substrate which allows the light to penetrate light shield at the cartridge)

As we aren’t Hollywood movies or politicians, we don’t have the need to tell you what or how to think. Take a look below and judge for yourself what look may suit your tastes better.

Just being honest here.
To a darkroom printer they both look pretty bad, at least at the shown developing/shooting conditions. Closed shadows, close-to-blown out highlights…Good luck getting decent prints out of those those. Of course for people who scan only and print digitally this may not be a big issue but I don’t see any reason to go with any of these “not sure what it is” films over more flexible, reliable and “in the game to stay” films from Kodak, Ilford and other established companies.
For me Streetpan above
As a darkroom printer myself, I have at times run into the same challenges noted above with StreetPan. That said, I do like using it for low light conditions or at night (or even days that aren’t bright & sunny). If I had to choose based on the pictures above, I would prefer StreetPan.
Looks to me like the Silberra film would benefit from being shot at ISO200 with reduced development time.. It is not a 400 speed film, based on these images.
I tried two rolls of JCH 400 back in July/August 2018. I shot it in open shade, bright sunlight and overcast days. Developed it in ID-11 (can’t remember time or dilutions) following some research on the Massive Developing Chart. Developed the films separately, so I could adjust times based upon results.
I was disappointed in the results. I must agree with Amigo & Giovanni. Tough film to work with. I’ve been doing this for 47 years, so I do bring some experience to the process. I’ll stick w/HP-5 or Delta 400. Others will get different results and be happy w/the negs. Just not my cup of tea.
I’m glad new films are appearing and will appeal to photographers with different tastes.
