Phillip Mosness Posted September 4, 2019 Share Posted September 4, 2019 I'm aware that the prevailing belief is to overexpose older color negative(one stop per decade I've heard), but I'm wondering if the same holds true for Black and White as well. And on a side note, without any filtering, B&W is rated slightly differently between tungsten and daylight. Is this because it's more sensitive to the blue color temperature of daylight?

Site Sponsor Robert Houllahan Posted September 7, 2019 Site Sponsor Share Posted September 7, 2019 B&W definitely holds up longer than color. I shot some Plus-X from 1966 recently and I shot it as 25iso outdoors and it looked great. Link to comment Share on other sites More sharing options...

Philip Reinhold Posted September 8, 2019 Share Posted September 8, 2019 Kodak Plus-X is a 125 iso Negative Film. So rating it at 25 Iso is exposed around +2 1/4 Stops. Cheers! Link to comment Share on other sites More sharing options...

According to a list I found, 7231 Negative seems to have always been 80D/64T , but Plus X reversal has had a 50/40 (my favorite) and later a 100/80 version before they pulled the plug.
