Expo Dev does not calculate dev time for filters

Fedrik --

The Expo/Dev program calculates the exposure increase required by the use of a filter but there is normally no development adjustment required. Your blank films suggest a major exposure error; but there's also the possibility of some failure of development not related to filter use. Is it possible that you diluted the developer excessively or somehow contaminated it?

If you save your exposure records, check the exposures you used, and confirm that a filter factor was included, to be sure there wasn't a mistake there.
