Not seeing changes in developed TX400 when bracketing

[MatthewDunn]

I am new to Tri-X and have been bracketing shots - one a full stop under, one a half-stop under, one at what I think the exposure should be, one a half-stop over, and one a full stop over. Developed in D76 1+1 @68-69 degrees for 10 mins.

To be honest, I see very little difference in the resulting negatives. Is that just a function of the "latitude" that is associated with this film?

For reference, and in the event it matters, exposure was determined by measuring the darkest area in which I wanted to retain shadow detail with a one-degree spotmeter and stopping down two stops.

Thanks in advance for any thoughts.

Matt,

Have you printed the negatives?

As you are currently a bit rusty in your negative evaluation skills, you may be finding it a bit difficult differentiating visually between the results of your bracketing.

Printing them will reveal more.

That's fair. No I have not.

You might set the meter to incident mode, retract the dome... run the negatives across the incident sensor and take readings...

Very roughly, a negative might get 1/2 stop "denser" for each full stop additional exposure. So I expect you to find one f/stop difference between the lightest and densest negative in a series.

Interesting. Will definitely give that a shot.
