Impressions about Kentmere 400 ISO 135 film

Many film photographers have expressed interest in this new (budget) film from Ilford. I bought a 100ft-roll from Adorama and have been shooting it for about a month now (~10 rolls shot and developed already). I wanted to share my experiences with it.

Development: I tried developing it in ID11 at first, but negatives came out flat and the development time was a bit too long. I started using D76 soon after that, especially since 1gallon D76 packages are cheaper than ID11 (for the same amt of film develiping). Initially I developed in stock D76 using the recommended time, but the negatives were still a bit flat and on the thin side. I was using a thermometer, so can't blame the temperature on that.

Finally, I decided I added 10-15% to the developing time and my negatives looked much better. I use plastic Rokinon-branded daylight developing tanks and reels (adorama sells them under their brand too). I agitate gently every 30 sec for ~10-15sec and I get no streaks (I did get that at first, when I didn't bother to agitate regularly).

I pushed two rolls to 800 a week or so ago and it turned out quite nicely. A bit grainier than usual, but I don't mind. I think it should be pushable to 1600 too.

I shot mostly with Olympus XA that I got on the RFF Classifieds. Overall, I like the film. It's about half the price of the other films in bulk (HP5, TriX). You may need to experiment with developing times since the recommended time gives thin/flat negatives. It's good for experimenting and for people who don't want to spend much on film and development. Below are some examples.

Hmm... it looks a lot like the new Rollei RPX 400 I've been using lately. I'm assuming it's the same film (until someone proves me wrong). I tried first with D-76 1+1 but it came out too grainy for my taste. D-76 undiluted was better in my opinion. It's still a bit gritty but not too bad.

This one is D-76 1+1:

Inquisition de Espaņa,

ID-11 and D-76 are the same formula, which is why you got the same results with them. When Kodak introduced it in 1927, they published the formula so anyone could make it. Back then a lot of photographers made their own developers, and Kodak sold the raw materials to them. Ilford and a lot of others have used the D-76 formula to make their own prepackaged products under different names.

Thanks Chris

ID-11 and D76 have different recommended times though. The development time of the same roll of film in ID-11 can be a few minutes longer than in D76. Perhaps it's just a different dilution. Either way, I will stick with the Kodak product since it's only $7 or so for the 1-gallon bag.

D76 and ID-11 are not identical in all markets. Apparently (from an old Ilford contact) one version is identical to ID-11 and the other isn't. I think it's the buffering...

Cheers,
