I'm a massive Tri-X fan. It's great, but I was recommended Delta 400, and I have to say I am VERY impressed. It's fine-grained, has great contrast, and came out with some great results.

Good quality with better speed over Delta 100.

This film gave me the exact tones and grains I was hoping for as I wanted to great something a little different for a friend of mine who loves Wallace and grommit

Very easy film for a beginner to work with and I have had experienced photographers comment on how forgiving this is to use

Recommended by me for a experience levels.

Works just as well outside as it does inside

Go to B/W film for me. Love the smoother grain compared to films like HP5 and Kodak Tri-X. Allows greater levels of detail in my opinion.

I have only used this film once and I doubt that I’ll try it again.
Most of the other reviews describe the film as “versatile and fine grained”. They also rave about the contrast. I found the grain ugly and intrusive and the detail poor. I usually use xp2 or hp5. I much prefer the fine detail that you get with xp2 and find that hp5 has far more pleasing grain. The contrast was ok and I could see it working well for outdoor portraits where you wanted a bit of grit in the image.
I used this film over the winter in a compact camera (Pentax espio 120sw) that has a slight tendency to underexpose. Nevertheless, I expected way better results. It seems a rather unforgiving emulsion to me. The film is significantly more expensive than either xp2 or Hp5 and, on my single use, I can’t say that the extra cost is justified.
Even the shots that worked had me wishing I’d put trusty hp5 in my camera.
