    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

    I've only seen rounded corners, sorry.

    The rounded corner does not effect the image at all. I also cut my film from 8x10 to 4x5 and the rounded corner gets hidden in the film holder rebate. So go ahead and have some fun.
