Using ID-11 at 1+3

[david b]

I shoot HP5+ at 250 and have been developing with ID-11 at 1+1.

Will I see any noticable difference using ID-11 at 1+3?


thanks...

IIRC D76 1+3 (or ID11 1+3) have more grain but also more sharpness.

The solvency effect of NaSulfite is almost gone so you'll get a "Rodinal-like" development.

I don't mean to be a smartass, but if you use the same development time, you'll see a big difference.

You'll have to figure out the adjusted development time to derive the same Zone VIII neg value at 1:3 that you currently get at 1:1. Perhaps someone here could give you a starting point...

Sorry, only speculation: have not tried it. Have only gone in the other direction: HP5+ rated at 1600 in stock ID-11...

According to Anchell and Troop, 1+3 should indeed give increased sharpness over 1+1 (they were actually writing about D76). Ilford HP5+ data sheet gives suggested times for the different dilutions (around 50% longer for 1+3 than for 1+1 @ 400ASA). Not sure if this is necessarily a good idea with a fast film though...

Cheers, Bob.

I've used ID11 1+3 on a couple of rolls of FP4+ and Delta400@200. I only noticed a very slight difference between 1+3 and 1+1, perhaps slightly larger grain clumps and a little sharper with the former. You'll need to double your development times give or take a bit.

The advantage would be secondary, but interesting: at 1+3 it will be safe for reduced agitation, encouraging greater shadow density relative to the highlights, and a long straight line. The overall look is very smooth, and clean, with the classical notion of fine grain ( regular, and not clumpy ) . It is a very nice way to develop film. 5 seconds of agitation every fifth minute is safe, and reliable.

You could if all else fails download the PDF file for HP5 from the Ilford website!

ID-11 1+3 is excellent with HP5 at 200. Provides maximum sharpness that way with less solvent action. Ilford list 20 mins at 20ºC for EI 400, so reduce by 20% for EI200 = 16 mins at 20ºC.

Marginally sharper than 1:1 with much more grain. I would reserve this for slow films. Delta 100 gets a little grainy at 1:3.

Mke sure you use enough stock, 4 oz, per roll. That means you need a two roll tank for 1:3.

I used ID11 @ 1:3 and found that (as expected) it dealt admirably with high contrast scenes, but you do pay the penalty of increased grain. I prefer it at 1:1.
