Trix and hp5 are not similar.. explain pleaseI have used the 4x5 - nice film, for me it is very similar to HP5 or TriX
Tri-X and HP5 are both 400 speed, traditional (not t-grain or tabular grain) films. They produce not dissimilar results although I do like the look and overall contrast of Tri-X better. I've shot the Bergger Pancro 400 in 5x7. It was nice overall but I got frilling when I developed it in Pyrocat HD. If the problem exists in 120 as well, that would completely rule it out for me.Trix and hp5 are not similar.. explain please
Thanks Peter
I have yet to try it but will at some point...supporting kodak and ilford right nowTri-X and HP5 are both 400 speed, traditional (not t-grain or tabular grain) films.

There is a link to an English language PDF data sheet on Bergger's product page.Anybody know/have the spectral sensitivity data?
They may not be exactly the same, but they occupy the same (quite crowded) product space of traditional grain ISO 400 black&white emulsions. Is it really so difficult to create a product which brings something new to the table, like a true ISO 1600 emulsion? Or is the ISO 400 market so much bigger than anything else, that there is enough room for such a multitude of products?Trix and hp5 are not similar.. explain please

Now that you mention it, while Tri-X and HP5+ stop at 650nm, Pancro's red sensitivity goes till 680nm. This is still not as far up in wavelength as typical bayer sensor filters, on the other side, the human eye appears to cut off at 650nm. Since Chlorophyl has a Dead Link Removed, I wonder whether this seemingly slight difference in cutoff wavelength is a lot more visible than one might think.Thank you! According to their data, it appears to have slightly more red sensitivity than the average B/W film.
Not a clone. .probably made by ilford under contract with the Bergger formula
Regardless hood to have cjoices

Probably the formula itself was done at Ilford laboratories by Ilford engineers; most likely Berger direct them on what result they wanted.
Still, I welcome new films.
What about Fomapan 400? it goes almost to 690nm according to their datasheet.
Nope. If I'm not mistaken when Panchro 400 was first unveiled in large format it was said to be a collaboration between Filmotec, Bergger and Innoviscoat.
???Amazing that the #2 fast food company (behind McDonalds) would get involved with Filmotec and Inoviscoat!
