‘One Third Keepers’ with Kentmere Pan 200 and a Minolta SRT 101

By Bob Janes

The idea of ‘One third keepers’ came out of online chats I took part in about 15-20 years ago.  We discussed hit rates of chosen to unchosen shots and whether digital photography had just become ‘spray and pray’. The general consensus was that, allowing for bloopers and duplicate ‘insurance’ shots, a reasonably successful roll of film was one where you would be prepared to share a third of the resulting images.

Minolta SRT 101 / Kentmere Pan 200 / Fomadon R09

Camera and lenses: Despite appearances, this is one of a pair of SRT 101s that I’ve owned for some time. It featured in my review of the SRT cameras here with its original top-plate. I mentioned it again as an aside in an article about swapping body plates. Functionally this is a 101, with a plain microprism screen, no apertures in the viewfinder and no working hot-shoe. It just has a slightly thicker top-plate with some misleading engraving on the front. The change is purely aesthetic and I start to feel a bit shallow when I explain about it. Luckily, there are not many situations where such explanations are necessary. In my defence, I genuinely think all SRTs are ‘Super’.

The lenses I used were a nice fast Rokkor 50/1.4, a Rokkor 45/2.0 (a personal favourite) and a surprisingly useful little Marexar-CX 28/2.8.

Film and processing: The film was Kentmere Pan 200 (K200). This was the second batch of processing I did of K200 and I used the same developing times as the first film (16:30 in 1:50 R09). The resulting negative strips were scanned as TIFF files by a Plustek OpticFilm 135i scanner and processed and output as web-sized JPGs in DXO PL 7 with a final tweak in PSP.

Pictures (12 of 36)

Frame 12: The ‘Dom’ at Cologne
Frame 14: Hotel corridor
Frame 16: Telecoms tower behind old railway sidings, now flooded as a lake, Cologne
Frame 18: Shadow in the upper room of the gatehouse at Upnor Castle, Kent.
Frame 21: Upnor powder room stairs from the top
Frame 22: Powder room stairs from below
Frame 23: Brickwork and crumbling plaster at Upnor Castle
Frame 24: It’s a bold yachtsman who moors up there..
Frame 25: Door furniture at Upnor
Frame 26: Upnor Window
Frame 30: Tower of Rochester Castle open to the sky
Frame 32: Worn steps at Rochester

 

Frame 35: Main Hall void at Rochester

Every time I come back to the SRT 101, I’m more impressed by it. I think it might be the easiest and most practical manual exposure SLR I’ve used – and you can get some lovely SR-mount lenses for it.

K200 merits some further investigation – always good to see another affordable film option. Looking at the grain and the density of these negatives, I’m wondering if I’m over-developing at the times I used. I might try cutting down to something closer to 10 minutes with R09 as an experiment for future films – and/or possibly laying my hands on some Microphen or Perceptol which I have official times for. Perceptol worked well with my grainy 16mm images).

I notice that K200 seems to dry with a slight inverse curl (it domes on the emulsion side). This isn’t quite as easy to scan as other Kentmere and Ilford films (which dry very flat), but it is much easier to deal with than the massive curl I used to get on Tri-X and NeoPan.

Do you weight the bottom of the roll when you hang it? Do you use a wetting agent following your last rinse?

Just curious about your curl.

Great shots Bob! I ordered the 28/2.8 Biogon last night.

I confess, I just use a few drops of washing up liquid.. The Kentmere 100 and 400 and the Foam I've been using recently dry dead flat.

Great shots with a simple gear, Bob! I especially like the frame 14 (the corridor). It reminds me of the corridor scene in the movie "Barton Fink" by Coen bros., as well as the corresbonding scenes in "The Shining".

This resonates with me on several fronts Bob. I have had several Minolta SLRs with excellent results. I have also climbed the hundreds of steps up the tower of the Kölner Dom you feature to see Grosser Peter, the huge bell there. The cathedral was like St Paul's, with devastation all around it from wartime bombs but somehow survives almost intact. I remember there was a lot of plain glass in the windows in 1956.
Great shots as usual. Thanks.

Minolta made some really nice lenses, it's good to see them being put to good use. But the 'One Third Keepers' would certainly have been a bone of contention when I was at college doing photography in the 1970's. Formal groups and weddings aside three good street or walking about photographs from a roll of 36 was considered a good average, even Bresson, Winogrand, Friedlander etc. matched this expectation if you look at the contact sheets. But 'one third technically proficient' (or more) photographs is probably a reasonable expectation for anybody immersed in photography. And pro rata I think the hit rate is similar for digital for anybody who can edit down their own work, but that's another skill.

I guess we all have our own standards - I guess by keepers I'm saying presentable rather than claiming as good... Thanks for the comment!

With ultra fast frame rates the spray and pray feature of modern digital photography has reached new heights. With choosing that perfect composition amongst hundreds what people do (I have been lead to believe).
It's one reason why I prefer old slower digital cameras, they enable me to shoot as with Film - carefully and with intent in every shot.
Delightful photographs, every single one has lovely translucent use of light and compositions are very harmonious and pleasing.
Thanks Bob!

My first film camera was a minolta sr1(?) With a 55mm lens so your post brings back (vague) memories. Some lovely images especially the stairs, steps, powder room and door. Have you tried semi-stand development - the lazy photographer's way?

I like your one third keepers idea. Personally i would reduce it to one fifth :-) Very good results Bob !

The one thing I really like about Kentmere 100 and 400 in the 120 format is they DON'T CURL, and using the Easy120 it's a crucial consideration for me. The 200 does have a prominent curl, so unfortunately it's not a film I'll use again. I'm fine with the 100 and 400 so not a huge loss.
