    It's shoddy and ludicrous, not to mention unnecessary, in all cases.

    Agree and what a ludicrous thing to do. Patience is a virtue. Respect the process and don't look until all the unexposed silver is dissolved.

    Turning on the lights in the stop is questionable and I only do it for paper test strips. Turning on the lights BEFORE the stop, well that's flirting with disaster. Turning on the lights after half the fixing time? May not be necessary but is totally safe. I did that on negatives I developed in high school in 1980. They're still fine.

    Not all of us routinely have film leader for checking clearing time.
    As Roger says, lights on after half or so of the fix time is no problem.
    Along that line, if you leave it in the dark for your expected fix time without inspecting it, you don't know if it cleared at 1/4, 1/2, 3/4 or 90% of that time.

    But what does it matter if you over fix by a couple of minutes?

    Well, it doesn't have to be film leader and it only takes a sliver. Even if you only shoot large format, you can buy one roll of the cheapest 135mm film you can find, and it will last you a very long time. It's a cheap way to test your fixer and determine clearing time.

    I test with film leader myself, most of the time since I use a Jobo. But I do check in the tank, because it's easy to do, when I develop with an inversion tank (usually that means I'm using Diafine.) You don't have to of course, but I'm just defending the people who do from the cries of heresy and the crowd trying to erect the stake and gather firewood. It won't hurt a thing to expose to light half way (or even less) through the fix.

    Why do you care?

    Follow the manufacturer's instructions. I guarantee they've done more extensive testing than you have.

    Last I looked, they said it was ok to expose film to light after 1/2 the fixing time.

    Hi Roger,

    Yes, I believe that's the recommendation that I've seen on commercial fixers.
