> Your thoughts on pre-rinse? Remember, I'm not using rotary.(posted 8315 days ago)I never use a prerinse, nor have I seen any need to, when using manual intermittent agitation or when developing sheet film with rotary agitation in a Unicolor tube. I only use a one-minute prerinse with the Jobo solely to eliminate airbells.
My standard manual agitation scheme is to bang the tank a couple of times to dislodge bubbles, then give 30 seconds initial brisk inversion agitation followed by two brisk inversions every 30 seconds. It shouldn't make any difference between agitation at 30-second intervals or one-minute intervals...but it may.
I also use a half-full tank with just enough solution to cover the bottom (loaded) reel.
For HP5+ in Ilfosol-S 1:14 I'm seeing slightly finer grain and slightly higher acutance than D-76H 1:1 or 1:3 , but _lower_ acutance and lower graininess than Xtol 1:1 to 1:3 or of course Rodinal 1:50 to 1:100. Of particular note is a more S-shaped curve than D-76, which is pretty much dead straight above the speedpoint.
