As previously indicated, I have no interest in the matter, so will run no tests. It's the OP's interest in knowing about how an irrelevant factor affects life expectancy of black and white negatives that's being discussed, not mine.

If it's enough for the OP to "have fun," fine. That's why I previously posted "have at it." Just don't rely on his "results" as being in any way meaningful.

Certainly not, but such a lack of rigorous inquiry and reliance on anecdotes is what leads to absurd decisions in other areas of life. Citing but one current example, refusal to have children vaccinated, thereby causing public health crises.

The public lacks interest in or understanding of scientific method. Promoting, rather than denigrating, rigorous inquiry is what I'd expect and hope for from someone who claims to be a scientist. I guess not. :sad:

Ease up buddy it's in no way as serious as vaccination...

A. I'm not your buddy. B. You take things as casually as you like, I'll take them as seriously as I like.

... It's not that serious...

…Certainly not…

...it's in no way as serious as vaccination...
And anyone who read my post knows I didn't say it is. What I did attempt to communicate was that sloppy thinking in one unimportant area tends to spill over into more significant arenas. I obviously failed to reach you. Perhaps others will get the point. My posting anything further on that subject in this thread would be redundant, so I won't.

Thank you for your kind words pdeeh!
I´ll keep asking! :smile:

Photographic negatives on film are not intended to be displayed. They are usually kept in dark storage envelopes, boxes, or drawers. Negatives are meant to be copied, either by contact exposure or in an enlarger. Exposure to light during the copying process does not damage negatives. However, prolonged exposure to direct sunlight or to artificial light sources is not recommended because these factors may embrittle the gelatin layer.

This isn't rocket science... We're not trying to prove something scientifically... Just mere curiosity


If the OP were interested in mere speculation then what would be the point in asking the question in the first place? There is far too much unsubstantiated crap already on the internet. Forgive me but I thought that the purpose of APUG was to give the very best (accurate) information possible.

It is true, I´m not really interested in speculation, that is why I thought I´d ask here, after searching for information on the internet, to find out whether I had missed something in my search and whether I could learn more on the topic. I think the conclusions here, as far as I understood, are that there has not been extensive and specific research on this particular subject and the reasons are now clear to me, i.e. the interaction between light and processed black and white film has negligible effects if any, the most significant one being possible film base embrittlement. Thank you all for your answers.
