I have just used my first rolls of the new Ilford Delta 400 Pro, some rated at 400 and some at 800. All processed with Ilfotech HC at 1+31. I have not done any controlled tests, but my initial reaction is that the film is a real improvement - surpassing all other b&w films I have used in this film range. Good tonal range, very sharp and fine-grained. It seems to push better - not becoming too contrasty as a result. Indications are that it is a true 400 film - I suspect the old Delta 400 may not have been.(posted 8554 days ago)
