    Great idea. Downloaded it.

    I think that the column that says "N+.5", "N+1", etc. should be labeled "reciprocity correction" rather than "contrast," since that's what it seems to refer to in this context. I'd also specify for clarity that the tables for "Tri-X Pan" are for "Tri-X 320," since some people may want to use this for Tri-X 400 as well, though I suspect the correction is for all intents and purposes the same.

    Maybe a later version you could add in bellows factor, calculable by various methods, and filter factor, to produce a result with all the relevant components: base exposure + filter factor + bellows factor + reciprocity factor based on the sum of the first three elements.

    Then the real bees knees would be a light meter with Zone system calculations plus all of the above.

    Just downloaded it and agree, it is great tool to have. I like to have the timer right there as i rarely cary a watch and therefore need to rely on counting.
    Look forward to see future updates.
    Thanks.

    Yeah, its probably not clear, it's the required development compensation so a clearer label might help.

    Thanks for downloading and your good ideas for the future.

    Sorry, no plans, the development environments, even primary languages, are very different.
