Exposing Tri-X Correctly

[SNAKECHILD]

Alright, I've seen other topics about this, so sorry about making a new one....but question for you all.
I'm a complete n00b.

I have a Nizo 561 Macro that I want to shoot some Tri-X 7266 in.
So far it seems the best bet is to set the filter on 'Bulb' so it will read the cart as 160.
But in daylight it will still overexpose by 1/3 of a stop.

So to compensate for this, I should manually set the light meter 1/3 to a smaller f stop (ie. 5.6 to 4.
OR to a larger f stop, such as 5.6 to 8 ?

Sorry if this is a really awful question, just trying to expose it properly. Thanks!

Just shoot it rated at 160 - it is not really a problem unless you are shooting in really bright conditions, in which case tri-x isn't the right film stock anyways.

You would need to adjust the light meter so that it let in a 3rd of a stop less light - if you had f5.6 you would need to move the exposure needle a 3rd of the way towards f8 - no more.

THANK YOU !!!

I shoot mostly Tri-X. I also use an external light meter most of the time.

If I'm shooting with tungsten lighting, I set the meter to 160. When I shoot in daylight I set the meter to 200... unless I am using a ND filter over the lens, then I make the appropriate adjustment to the meter.

So far, it's all turned out well.
