I need to develop a Fomapan 400 film using Fomatol P (Bromophen). Does anybody know where should I look for the developing time charts? The film is in black and white.
Short answer: you can not find the time chart because it does not exist.
What you need is a film developer. The concentration of chemicals in film and paper developers is greatly different, to such an extent that they are not interchangeable.
To develop your Fomapan 400 you need to buy a film developer. Fomatol P will not do.
Included in the spec sheet is the information you are seeking.
Or maybe not. From a comment by Jindra Lacko
Pointing to google is fun, but you should have noticed the slightly different spelling of Fomatol P vs Fomadon P. These are two different developers.
If someone else finds this question and really means 'Fomadon P', rather than 'Fomatol P', the information they need is in the chart above. 'Fomatol P' is not suitable for developing film.
¹ At least, before this answer was posted, it was.
Here is screen shot from the massive dev chart.
i could not find Fomatol P on it, perhaps you meant Fomadon P ?
A great resource.
