Clearing Times for 400TX Longer than HP5 Plus

[Lamar]

Anyone else notice that fix clearing times for 400TX are consitently about 50% longer than for HP5 Plus? Just wondering why?

Higher Iodide levels, Kodak films do take longer to clear.

Basically same reason T grain films take longer, Kodak uses similar technology to manufacture TriX even though it is traditional grain emulsion.

 

[Gerald C Koch]

Higher iodide containing emulsions also deplete fixers faster than conventional films.

I hadn't noticed TX taking longer to fix than HP5+, but I sure noticed a difference with TMax films...did not know the iodide thing.

I do not like that tablet based grain so sticking to tradition grains has the added benefit of shorter fixing times and not worrying about the pink stain.

What does the higher Iodide level in Kodak films contribute compared to the lower levels in Ilford films?

Thanks

Thanks all.

Helps increase sharpness and fine grain. Years ago some acutance developers included Iodide for the same reason.

Various things eg

(there was a url link here which no longer exists)

Tx is finer grained but needs more fixing & may have a more difficult toe, YMMV, since I fix by inspection I miss out on some possible problems.
