It's a long time since I used Ilford developers,so I could be going up a blind alley, so correct me if I'm wrong, but isn't DDX the liquid form of ID11?

My understanding was that it was formulated specifically for use with Ilfords Delta films when they came out. So perhaps the ID11 equivalent for T-grain films but not a liquid form of ID11. But who knows what's in it

Yes, my understanding too re' DDX - was formulated especially for Delta.

Flying off at something of a tangent... However, I don't think Delta can be called "T-grain" in the same way T-Max is. Not sure, but I seem to recall that it uses epitaxial growth (although I think that uses t-grains as the base) to add the impurities (bromides, iodides etc) to the edges of the crystals. There is a picture of what looks like an epitaxial crystal on the Harman site but it does not say what it is a crystal of... (http://www.harmantechnology.com/DotN...0/Default.aspx - about half-way down). And that just about exhausts everything I (think) I know about the subject ...

Not been using it as that. No wonder I have been getting negative reactions.

Well Bill, you can either be a gigolo or an analogue photography afficionado. Both might be fulfilling but cannot be combined. Life's too short to be an expert in both fields.

Dave. My only direct comparison with DDX and ID11 is in two rolls of D3200. The ID11 negs were much grainier even at 5x7. I'd be surprised if there was any real link between the two. Ilford is pretty restrained in it's marketing blurb in general but even it recommends DDX as the developer for its Delta films and I think this has some basis in fact/research.

While I generally like "milk and water" constrained companies in terms of claims I think that it could actually help it's position if it tried out and tested a bigger range of films with its developers.

I suspect the developers are more versatile and suitable than it gives them credit for.

Then again, I'd have tried launching 5x7.5 paper to match 35mm negs if I'd had any say in matters Ilford

Ah, but put a 10mm border round your image, which the easel will take up, and you are back to 3:2 so unless you are printing borderless 5x7.5 doesn't make sense. Does it?

According to an Ilford source, no. Ilford DDX is the hobby sized version of Ilfotec DD which Ilford found to work particularly well with their then newly introduced Delta 3200 film. DDX was introduced around the same time or just after Delta 3200 if I recall. Ilfotec DD is a modern liquid concentrate designed for use in photo-labs for Dip & Dunk processors and designed to be replenished, hence the initials DD.
Ilfotec DD and DDX are buffered-borax liquid concentrates which is probably why some people consider them as being a liquid Microphen type.
