    I have a one question about ND filter. I have only Hitech 3,0 ND Pro Stop filter. I used this filter on digital camera. This filter creates blue color cast on digital pictures. Is this color cast problem with BW negative?

    I've used Delta 100 for many long exposures. No problems.

    I'm still not sure what you don't like, specifically about the sky. If you are talking about the grain, keep in mind Perceptol is not a sharp developer, so you will not get very crisp grain at 1+1.

    On BW film; there will be no problem with blue colour cast.
    Don't forget that the sky is moving during your exposure.

    Why are there no speaker jacks on a stereo camera?

    Maybe grain, maybe rendering blured sky. This is my first try with long esposures on film. Do you have a recomendation for developer? Could I see your pictures with long exposures or do you have only paper photos, please?

    Thak you.

    Moving sky. Yes, I know.

    During these long exposures the clouds are moving effectively creating underexposure to the sky. The scanning may be exacerbating the grain effect also. If you made a print in the darkroom, burning the sky in with appropriate contrast, I think the results would be more to your liking.

    My long exposures don't have sky in them so I don't think they would help. I was just using myself as an example of someone who regularly uses Ilford films (and Kodak films) for long exposures and there are no negative effects.

    Well, i did use this filter, B+W 3.0 ND, but i am sorry that i always say i have experience in digital, so on my digital shots with this filter i don't like the overall mostly the sky look, so i don't know if it will be worse with film, but i can't tell until i give it a try, hope i can have that time to do it and show the results.

    I would like to find reciprocity characteristic for Rollei ATP 1.1. I am looking for this characteristic, but I cant find it. Maybe, this film could be a good idea for long exposures. No Ilford film, but......

    I found some pictures with Ilford Delta 100 on internet - long exposures.
