    Would it be possible to see a best rendition comparison of shadow and highlight areas?

    Nice. I can see the better separation in the shadows in the one with the higher contrast.

    White dust (negatives) can also be due to embedded dirt during development, in particular the drying stage. In a test of several labs a couple of years ago we had difficulty finding one that kept a...

    If you go to Wheeler for the cranes the best times would be either sunrise before the flights to find food and evening when they return to roost in the water. They can't swim, so they'll be in the...

  10. Re: Travelers: New X-ray machines WILL ruin your film

    I agree. A sheet oriented orthogonal to the source and in the center of your baggage.

    Re sending film through the mail, why should that be assumed to be a safe mode?

    Here is some reading material that might help. One article references possible use of periodic exposures in the CT slice method, which has some implications for film (stripes?). Looks like you can...

    Re: bellows factor app

    Just use f-stop inches. For an 8 inch lens (“f8”) open 1 stop at 11” (“f11”) and 2 stops at 16” (“f16”). Substitute f-stop cm as needed.

    Re: Super Large Files to print

    In addition to the memory, which seems too low, when you say your printer supports 16 bit, have you verified that the driver you're using does as well? I.e. is the entire path 16 bit?
