    Re: Help With Epson V800

    Or some "stuff" on the calibration strip (above the scanning area). More likely, as more exposed to outside dirt than the sensor.

  22. Re: Density Readings from FP4 negatives in Pyrocat-HD using a spotmeter

    First off, something's wrong with your Zone assignment

    f/45 1/400 is a lot less exposure than f/16 1/25. So the former cannot be Z_VIII whith the latter being Z_I.
