been using it for years.

This worked exactly as described. I used it to develop some Ilford HP5 Plus and every thing came out great for me. As long as you have air tight containers to store you stock in this is quite a deal with 5 liters of stock for just $.

I got this developer because I developed a roll of Ilford HP5 Plus in Kodak D-76 with terrible results. I figured that using the company's product with their film would yield better results and it did. I love the tonal range that I get from a roll of 120 HP5 Plus on either my Mamiya RB67 or my Rolleiflex 2.8. I do mostly street photography and the sharpness this developer produces with 400 speed film is phenomenal. I have also done some portraits and they come out tack sharp with very fine grain. Very impressed.Now, I have also read that D-76 and this ID-11 are just about identical and that people get great results developing HP5 Plus in D-76. To that end, it may just be that I made some error in developing that earlier role. However, my own experience tells me that this developer is much preferred. You can't go wrong with this stuff.

I have been using DD-X and Xtol until someone suggested that classic developers such as ID11 or Kodak's D-76 can work better for classic films, especially the slower ones. I purchased ID11 to try it with FP4+ and Kentmere Pan 100. The results are great and very much comparable to Delta 100 in DD-X. Great tones, extremely fine grain, and it is much more economical than DD-X. I haven't tried processing Delta film in ID-11 though...

I use it for developing all of my Ilford films and find it has a wide latitude and is fairly easy to mix and put up in 500ml or 250ml bottles for easy use at stock strength. Very good results.

Kodak's D-76 switched packaging to plastic bags, and the developer oxidizes in them because plastic bags are not impervious to oxygen. So my D-76 from now on is ID-11. Until they change the packaging, D-76 will mix up into a solution that looks like weak coffee. Spare yourself the money and hassle. Get ID-11.

I just started shooting film & where I live in New Zealand my local store wanted to charge me ~$28USD to develop ONE roll of B&W film, so developing made sense really quickly... Having not had much experience in developing I can't speak for how this compares to other developers but I had found it very easy to mix & very versatile to work with (also really reasonably priced), very happy!

For many years I wouldn't use anything other than D-76 to develop my film (Tri-X and HP5 Plus). I decided to try ID-11 as an alternative, primarily because it's available in 1 quart packaging and I don't shoot enough film to work through a gallon of D-76 before it oxidizes. I had read that it's pretty much equivalent to D-76. This appears to be the case. My first two rolls of Tri-X developed in ID-11 (1:1) came out just fine, with good grain structure, open shadows and detailed highlights. Recommended, especially if you want to work with smaller quantities of stock solution.

After using d76 for decades I switched to ID-11 after seeing better results from a friend. It’s excellent for pan film!

I get great results with ID-11. It is easy to use and lasts well. If properly stored I get good results well beyond the stated shelf-life of the mixed developer. Make sure you have sufficient glass storage containers for the full volume when mixed and can move part-filled containers to a smaller container to minimize the air inside during storage. I wish it came in a size between the 1 liter and 5 liter quantities.
