I have 400 film that was pushed to 1,600. I am using HC110 developer. How long should I develop it? Thanks Don

Not an answer, an addition to the orginal question. The film is TRI-X Plus

You essentially underexposed the film by two stops, so don't expect to see much shadow detail regardless of how long you develop the film. To preserve any of the midtones and keep the highlights in check you should probably develope the film 30-40 percent more than recommended.

You also should set aside the HC110 and use a developer that gives full shadow speed. Try Microphen, DD-X or Acufine.

i use t-max developer for pushing tri-x. same deal, about 40 percent increase in time. t-max works well for this. i would never go past 1600 with tri-x. you will have clear patchs of nothing for shadow area.

I've been shooting Tmax 400 as though it were 1600 film, and taking notes as I process. I use Tmax developer mixed 4:1 and re-used, adding 1 min after 17 rolls and discarding after 30 rolls. I modify the factory recomendations by 125%. Tonight I produced successfull negatives by taking my standard time (modified by 125%) and then modifying that time by 1.66 (supposedly a 3 stop push). Perhaps you may find success by increasing your development with HC110 by 1.66.
