I put rolls of HP5 into my Olympus 35RCs and set the ISO to 800. I have 2 of these, so figured that would be a good idea. Stupidly though, I didn't think that the meters would be slightly diffferent, and the RF patch is harder to spot on one. So both focussing and metering weren't exact. Rodinal – 6 ml + 494 ml water or 10 ml + 990 ml water – 30+30 (minutes) with 10-second stir at the start and midpoint

No, I only use this tone with people who waste my time by posting irrelevancies over the why's and wherefore's. It's my business as to why I want to do it. . If you don't know the answer, say so. You've been spectacularly unhelpful by the way - I can see your profile descriptor is pretty accurate...

To start with, IMO, the DD-X isn't 3x better. It's not noticeably sharper (take my word for it because forum compression will kill these screenies) and whilst the grain is lessened, it's really only visible at 100% which as any pixel peeper will know isn't that useful. Ilford Multigrade 1+4, 1 minute resin coated (RC), 2.5 minutes fibre based (FB). Multigrade developer gives a slightly warm tone compared to Ilford PQU (also at 1+4), which I also occasionally use. Both can be used at 1+9 using longer development times to achieve the same result. Paper The main reason why this developer is still on the shelves today is because of just how good the results are with faster films. Which I’ve found to be true in my own use as well — the day that I truly started loving Ilford Delta 3200 was the once I started developing it with DD-X. The results were stunning compared to what I was used to getting with HC-110.

Going with the Ilfosol 3 example above, I would do 2 x 30 minutes and stir 10 seconds initially and 10 seconds before the second 30-minute time slot. Nothing else changes. Why break it down into two slots instead of just letting it stand for 30 minutes? Depending on the chemistry I am using, I may want to enhance the effect of that chemistry slightly. So, the second stir at the midpoint works harder to produce the desired effect. Dilution tends to allow the highlight development to exhaust in between agitations, an effect which will be enhanced by increasing the time in between agitations (what is known as "stand" and "semi-stand" development). Such increases in time can also lead to muddling of consistent tones in an image due to the buildup of byproducts from the development process (such as "bromides", etc.), and this problem is worse with some developers yet essentially non-existent with others. However, the dilution alone along with consistent 5 second agitations at one minute intervals will generally still tend to improve shadow detail and highlight separation because of the dilution of the developers.

As you can see from the above DDX recipe, my cost per roll goes down with SSD. Now, I use 15 ml per roll or 25 ml per two rolls (or 12.5 ml per roll). I get 1,000ml / 25 = 80 rolls if I develop two at a time or 1,000 / 25 = 66 rolls if I develop one at a time compared to using 60ml per roll in normal development. This makes DDX quite affordable to use regularly. I'm getting timings which vary between 13 minutes and 20.30 minutes, which is obviously a fairly vast gulf and not really much help... Most scanners tend to struggle with high density highlights. and they respond badly to high actuance, as edge effects are accentuated by digital processing. I spent the latter part of 2018 and all of 2019 with Rodinal, and I made the descision to spend 2020 with HC-110, but to be honest, after my first few rolls, I found it delivered far superior results to Rodinal for the films I shot and the look I liked. HP5 in Rodinal looks terrible to my eye so it's not included here.
