Indirect window light, about 2 pm Beijing haze. Not sure what that compares to as far as Oklahoma light. Guessing you are brighter with less pollution ;)

Indirect window light on a hazy day will transmit less UV and the blue end of the spectrum requiring considerably more exposure for the x-ray film.

Apart from the pollution, I think you are farther north. Beijing = lat. 39.9042° N; OKC metro = 35.4676° N. So I'd probably need a slightly shorter exposure.

The great thing about x-ray film is that it's cheap so testing to find what works in each situation doesn't break the bank or anger the better half (too much) ;)

Re: Use of X-ray film: technical discussion with example images
This is an old thread, but I was wondering if anyone has used or seen x-ray film without rounded corners? Essentially, square corners. I have fuji green with rounded corners but I started to cut down the 8x10 to 4x5 with a safe light and not having a rounded corner on 4x5 might be a blessing. thanks
Re: Use of X-ray film: technical discussion with example images
I've only seen rounded corners, sorry.
