Ilford Ilfotec DD-X Black and White Film Developer 1 Litre

Product Information

Grain is much more pronounced, esp in the zone II & III shadows and there's a "kludgy", muddy look to the image - which suits the subject in this case. This grain is less pronounced through the tonal range, but it's visible, and nowhere near as clean as the DD-X shot. I may well sacrifice a couple of rolls of P3200 to compare.

I know the definitive answer is 'test it yourself' but Delta 100 is bloody expensive compared to Fomapan and DDX isn't cheap either compared to HC110... Like I said though, I am not versed in the particulars of how developers work, if you are, please let me know in the comments if dilution does make a difference in the amount of grain you get in your images.

It's also not helped by all the American forum users insisting on using Farenheit instead of Celcius and intermingling their terms for time conversions between 'x1.4' and 'add 175%' ... I'm a maths-biff at the best of times, so keeping this all straight in my head is a challenge anyway...

Pyro - 5 ml + 995 ml water - 15+15 with 30 seconds stir or inversions at the start and the end of the first 15 minutes. If you are using 500 ml for developing only one roll of either 35mm or 120, you still need to use a minimum of 5 ml (not 2.5 ml) of 510 Pyro. Learn more about how to handle film chemical waste here. This image was taken on HP5 pushed to ISO 1600, but you’d hardly be able to tell when using an incredible developer like Ilfotec DD-X. What is the difference between Infotec DD and DD-X? While the grain structure doesn’t seem to be anymore prominent between the two diluted developers, I feel the HC-110B dilution added a little more grain making the photos sharper. I am not sure exactly how developers work, but it is my understanding that the more you dilute it, the more grain you get. Kodak HC-110B Ilfotec DD-X 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.

Paper

Most scanners tend to struggle with high density highlights. and they respond badly to high actuance, as edge effects are accentuated by digital processing. The other issue is that I didn't actually want to use 1+9 as my ratio, but 1+6.5, due to the minimum solution requirement per film, and the probability/possibility that the characteristics of the developer change at weaker dilutions, which further complicates matters...

Ilford Ilfotec DDX 1+6, 9 minutes for Ilford FP4+ and SFX 120 (I process 5 rolls at a time and process FP4+ in the same tank with SFX). I was the Ilford Technical Manager responsible for chemical products at the time that DDX was specified and developed. In my opinion it is the best film developer, both in terms of performance and reliability, that Ilford make. The top line of the specification was that it give performance similar to ID11 powder developer but in a convenient liquid concentrate rather than powder. It was optimised for the Ilford Plus films as well as the newer Delta range and is based on a modern, more stable, version of Phenidone and hydroquinone. If you are unsure of what developer to use try Ilfotec DDX (in 1 litre bottles) or Ilfotec DD (identical developer to DDX but in 5 litre bottles). 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.Ilfotec DD-X is one of the very best film developers for pushing film. This developer is the perfect balance between solvent action (reducing the size of grains) and shadow enhancement. It is more expensive on a roll-for-roll costing, but I've also found that it's cheaper to buy a bottle than the more economical developers. It's a false economy, but sometimes it works for the wallet that way.

If you’re the type of photographer who often pushes your film and likes having a liquid developer, DD-X is going to be one of the best developer choices. DD-X will not let you down, no matter what kind of lighting you throw at your negatives.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... I generally use the manufacturer’s recommendations for film and paper processing, except for film development where I find the Ilford recommended development times rather long for my way of working. The low solvent action and enhanced shadows make this especially useful for fast films like Ilford Delta 3200, where it will reduce the grains just enough to have a pleasing appearance without eating the grains and lowering the film’s speed.
