    Default QTX exposure times

    I need a quick ballpark for exposure of QTX on 230 ct yellow mesh with a 250 watt photoflood lamp at about 20 inches distance.

    Anyone?

    Do a search in the forums for a step wedge test.

    Yeah, I could do that I guess. But then I would have to coat another screen for the test.

    I want a ballpark, so I can make a guess, mess it up, and end up doing the test anyway, as you suggest.

    I want candy, not good nutrition, because I'm in a hurry, and, well... I'm feeling a little half-assed today. And not so afraid of winging it.

    Thank you for the suggestion though.

    Okay, I did the step test.

    Turns out to be about 4 1/2 minutes.
