I think both IanG and David have expressed wise comments and, no disrespect to IanG, but I tend to agree with most of David's comments. If you will allow me to add a couple thoughts...
Xtol is a great developer, but like many things in photography it has its idiosyncrasies. For example, it will die without warning! This is the primary reason I stopped using it years ago. I have no experience with replenished Xtol so, perhaps, using it in that manner solves the "sudden death" issue. Or, perhaps the formula has been modified over all these years such that it lasts longer?
The problem with D76 is that the pH changes during storage of the stock developer which affects development; typically, one will see a rather dramatic increase in contrast. Therefore, I wouldn't recommend this developer to a beginner. I don't know if ID11 has this anomaly. I sorta remember using ID11 a couple of times back in the 80's and didn't find anything special about it. IMO, developers such as D76/ID11, DDX, etc, are what I'd call "middle of the road" formulas in that they don't have any particular outstanding qualities, but will provide a decent negative.
As my photo mentor used to say, "Ya need to get one foot on a rock!" I would advise a novice film photographer to pick a solid, long-lasting developer such as HC-110 or Rodinal (both have tremendous storage life), pick a solid fast(ish) film like Tri-X or HP-5+, one camera, one lens (say, a 150mm or 210mm if shooting 5x4), and go out into the world and shoot and shoot, and then shoot some more! If working in the wet darkroom, use the same enlarger, lens, paper, chemistry, etc, or, if working on the desktop, the same scanner, editing software, etc, until you are intimately familiar with how your chosen tools work and what result you can expect from them. Once you feel comfortable that you've got a good grasp on all that, then,
and only then, change one variable, continue working, and evaluate the results. Will anybody do this? No, but it's worth the thought...
Oh, and if Polaroid materials were still around I'd tell ya to skip the film and all that entails, and use Type 52. Seeing the results of your efforts while still at the scene is invaluable and, IMO, speeds up the whole learning process. Plus, it helps you to begin to learn what you want to say with your photography.
Thanks for listening. Stepping off soapbox now!
