    Re: New RETROPAN 320 soft

    Why would you call a supposed fine grained film "soft"?

    Their foma400 is pretty "retro" looking and is better shot at 320 or 250 so I guess I'm curios why a new film? Why now? I'm excited that there's a new film, but wondering how it differs. Hmm...

    Many companies made and sold Soft gradation films in the past so the term isn't new. essentially it's just a lower contrast film so will have a longer tonal range compared to other Foma films.

    It is not yet on the menu Foma shop. I'm curious about this film. I use Fomapan 100.

    OH!!! That makes sense!!! This changes my opinion entirely. Good for FOMA, however the soft comment wasn't known to me and probably other "newer" film people, I mean I've been shooting film for 20 years yet never heard that. Though only B&W and home processing for 4-5 years.

    Thanks Ian.

    Data sheet here:

    The lumpy characteristic curve shown on the data sheet is very peculiar.

    The spectral response is really interesting.

    Is Schwartzchild Effect the same as Reciprocity Characteristics?

    Am I reading this correctly that for 1 second exposure you need to open up 1 stop AND extend the time by 1.5? And for 10 seconds you need to open up by 2.5 stops and add 6 times the exposure time?

    Or am I totally confused? That's pretty extreme...

    I wonder why all the Fomapan films seem to all have the same spectral sensitivity with a rise from blue to red. Is there a reason they chose to do this?

    Hi Stone , a 10 second exposure would become 60 seconds 6X a 100 second exposure would become 800 seconds 8X,In the chart it gives the corrections in both exposure factor and f stops , But you don't apply both otherwise the 800 seconds would become 6400seconds over an hour and forty minutes which would be extreme .
