I was really looking forward to this but unfortunately the can was damaged and the photos came out foggy in processing :(

Despite its relatively high ISO for a black and white film, I find Delta 400 delivers surprisingly poor shadow detail. I noticed this when I first shot the film, so I put it down to the lighting conditions. To test that theory, I shot a second roll in much stronger light, only to find the same issue.
I also feel that the overall rendering can be a little conflicted. The film exhibits the noticeable grain you'd expect from a 400-speed stock, yet it also has the crisp, clinical sharpness that is characteristic of the Delta range. For me, those two qualities don't always complement one another.
Personally, I'd much rather shoot HP5 Plus or Kodak Tri-X. Although they're a little less sharp, I find they produce a more pleasing grain structure, smoother tonality, and images with greater character overall.

I nought this film specifically because I was going to a classic rally event and wanted something around 400. I’ve never particularly got on with HP5 in 35mm (different story in 120), so thought I’d give this a try, and I have to say I love the feel of it.

The grain isn’t just ‘noise’, but it adds to the atmosphere of the shots - and that’s where it’s visible, because in the right light this can produce really nicely smooth images.

I loved this for tracking shots. With a slower film you’d be shooting at f/5.6ish and potentially losing a bit of sharpness when zone focussing. The film let me shoot at f/16, and sometimes f/22, at about 1/60th, keeping most of the car in focus (when I got the tracking right!).

Shot with a Nikon FE and developed in ID-11 1+1.

My go to film aside from Agfa 400, perfect performance and grain, less flexibility than hp5, but still lots of give, excellent for technical shooting

Unsure about this one. I was expecting a bit more shadow detail but to be honest I think my XA2 has underexposed this for some reason so perhaps not a good test of this film

I was pleasantly surprised with the results of this film. I'm shot a lot more HP5 and when I got my scans I was pleased with the finer grain and the contrast out the box. A bit more expensive than HP5 and although cheaper maybe not as fine grain as TMAX 400.

It's a really nice film but I'm not sure I'd reach for it again.

Used this stock on a few trips out when the weather was unpredictable, so it was used on overcast days and on sunny days.

The speed is obviously good for overcast days so that you aren't struggling on lower shutter speeds, and it delivers alright results. I wasn't blown away by any of them, they had relatively muted contrast. The grain was fairly heavy, but that's obviously expected of a higher speed film and it doesn't look bad by any means, it helps convey the dull day.

On the sunny days though, I honestly really do not like the film at all. Again, there's not much contrast, perhaps even less than there was on the overcast days. The grain is also more pronounced and it isn't attractive at all. I've used ISO 400 film before on sunny days and loved it, though it was a colour stock, but this stuff just didn't do it for me.

Unfortunately won't be reaching for Delta again, but it's all about experimenting until you find your favourites, so I can't complain too much!

Examples: the street corner and view from the boat were overcast days, the standing stone and seafront were both sunny.

Grain is well controlled. It can, of course, be made more visible in post-processing if that is your thing or kept at rather nice levels to give both detail and a filmic look. It looks nice SOOC but I found it was easy to lift or add shadow without things getting too gritty. This also enabled me to recover photographs where I (my camera!) didn't get the exposure as I wanted it. I shot this on the same day as using the much cheaper Fomapan Action 400 which I found comparable in terms of quality and reliability but with perhaps a little more contrast. I will probably try a lower ISO Delta film next in my pursuit of more detail and even finer grain.

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.
