    Re: Sensitometer For B&W Film?

    Thanks for the info.

    I was under the impression that I would either need to correct for the daylight-balanced B&W film when using the X-Ray (green or blue) light units or get a proper...

    Re: Enlarged Film Negatives Process?

    None of the regular photo retailers have T-Max 100 8x10 in stock (B&H, Adorama, Freestyle) and in fact, it isn't even listed as an option. I can only guess that makes T-Max 100 a special order case...

    Re: Enlarged Film Negatives Process?

    Very helpful and some really good points.

    Bummer you can't find T-Max 100 in 8x10 which is a deal-breaker for me.

    Thanks, Drew.
