I’ve had some Fomaspeed 412 ultra-thin photographic paper lying around at home for quite some time. I actually intended to use it to produce large-format negatives for alternative printing processes, but my printer isn’t up to the job. Now I’d like to use the paper in my pinhole cameras. The description of Fomaspeed 412 states:

The ideal film for pinhole cameras (400 ISO, can be developed in a photo tray using paper developer).

Am I correct in assuming that I need to set my light meter to ISO 400 to determine the correct exposure times? What about the black shield effect... can it be compared to a specific film so that I can use that as a reference? I think those were my questions, many thanks in advance for your replies, best regards, Christina

Hello Christina No, the ISO rating of positive material isn’t comparable to that of film. You need to expose it for much longer. The exposure times for paper should be in the range of 5–50 minutes. Just give it a go.

Hi Christina, Have a look here: Tables You won’t be able to avoid doing some testing, though. It depends on the aperture size and the focal length, after all That’s what these tables are for: Dieter’s Pinhole Camera Page . Best wishes, Sven.

Hello Christina, The speeds of film and paper are determined according to different standards and are therefore not comparable. Best regards, Andreas

Hi Christina, Great suggestion! I really must write ISO-P there. The text has been copied over from our first website, which dates back to 1996 ;) Best regards, Mirko

Hi Mirko, while you're at it, why not include the conversion to film ISO as well? That'll save us having to do the maths. ;) Regards, Sven.

Bad news: Foma has just informed us, without explanation, that Fomaspeed 412N is no longer being produced ;) :( From now on, they’re only making the ‘hard’ version. Are you interested in the ‘hard’ version? I mean, in a pinhole camera the light tends to scatter anyway, so perhaps the ‘hard’ version would actually be better than the standard one...... I’d be grateful for any suggestions, Mirko Alternative: the new ADOX Printfilm 25 ASA (film) is available and not expensive either. It’s on the ADOX CHM Film page (a bit out of place – but I put it there because there was space ;-)

And where exactly can I find information about Adox print film? Many thanks and best regards, Christina
