• ILFORD ILFOTEC DD-X is a fine grain developer which gives full or increased film speed. Correctly exposed negatives developed in ILFOTEC DD-X have a full range of tones, with depth in the shadows, a smooth transition through the mid-tones and bright, detailed highlights. ILFOTEC DD-X is designed to complement the features of ILFORD films, especially the range of ILFORD DELTA PROFESSIONAL films. In particular, it is recommended for use with DELTA 3200 PROFESSIONAL film, as well as other black and white films from other manufacturers. Ideal for both manual and machine processing of film. Where continuous agitation is used in rotary processors without a pre-rinse, reduce the spiral tank development times by up to 15%. A pre-rinse is not recommended as it can lead to uneven processing. For Push processing development times are given for a range of meter settings are given in there development table. Dilution 1+4 with water before use ILFOTEC DD-X is supplied as a liquid for one-shot use and is available in 1 litre bottles of concentrate.

I'm relatively new to B&W film as I've only seriously gotten into it in the last couple of years. I've tried a few different developers, including D-76, a general developer and Perceptol for fine grain films like Pan-F. I found DD-X to be more convenient to work with initially as I didn't have to make up the stock. Also, coming in a smaller size liter bottle it seems to keep for a lot longer than Ilford says that it will. I don't do a ton of developing and a bottle will last me 9+ months. I also found after doing some film testing with Ilford Delta 100 sheet film that the developing times are actually relatively short with this developer. My "normal" development time is just under 6 minutes. About half the advertised time for this film. I guess this implies that DD-X is more of an agressive developer. I use it at 1+4 dilution. You could use it more diluted and stretch the development times, but I prefer to get the process over with quickly. Using it at this time and concentration I've not noticed any degradation in highlights or shadows. Before I did the film testing, I was noticing that my highlights were starting to feel over developed (with DD-X). Honestly, I've not found or noticed any downsides to DD-X.
Easy to use, great results every time
Used as described in the instructions to dev a roll of Ilford HP5+ 400 and everything worked as planned, awesome dev.
Tons of people use this developer, so it is easy to find data on develop times/temperatures all over the web for just about any film. I've developed Kodak tri-x 400 from iso 100 to 6400 successfully.
