Ilford SFX 200, What do you know?

[Steve Smith]

check out the documentation on http://www.ilfordphoto.com/products/product.asp?n=12&t=Consumer+&+Professional+Films# All the information you need is there for filter compensations

There's a bit of contradiction there. In the list of filters and exposure corrections it says to add four stops for their 89B filter but further down in the text it suggests an exposure of 1/30 at f5.6 with an 89B filter in bright sun. This is six stops more assuming 1/250 f16 (sunny 16) for its un-filtered ISO 200 state.

I simply rated the film ISO12 when using the SFX filter (R72 equivalent?) and the images came out perfectly exposed. That was four stops. So from an actual experience point of view 4 stops seems right. Rgds, Kal

That is correct at ISO 12
1/10-16 ~ 1/30-8 = 1/60-5.6
however 1/30 5.6 may give you better results for English weather

I made it two stops different instead of your one. I started with 1/15 instead of 1/10 so:

1/15 f16 = 1/30 f11 which is two stops more than 1/30 f5.6 which Ilford suggests for bright sun which we do get in the UK! (sometimes).

I have also used it at EI 12 in the past so I will use this as a starting point again. I'm quite interested in using it with a red filter too but again, I'm not sure about Ilfords recomendations. Usually I would add three stops for a red filter but Ilford suggest one and a half. I think I will call it two and rate it at EI 50. Time for some trial and error (mainly error I expect).

I used rangefinders with these films (easier to focus/compose) and at EI12 I got very good results with SFX200
I prefer to overexpose 1/3-1/2 stop so I equated 1/10 to 1/8.

Looking at another thread here I just ordered some Rollei Superpan200 (AGFA AVIPHOT) and will test as well.

SFX turned out to be one of my favorite films. I have used it with no 25 and 29 filters, both of which yielded pleasant results at ASA 200. I have developed it in D76, and the film is not particularly grainy.

Must admit, I wasn't over keen on the results with SFX doing landscapes, or street shots, filterless, but it rocks with an R72 IR filter.

Not in the Kodak Infrared league, but some nice contrasts between trees, grass and partly cloudy sky. With a large expanse of grass, looked like it had been snowing in winter. Throw in a weird colour cast I got from the scanner when I used colour negative settings, and the results were different to say the least. I need to shoot more of this. Maybe in 120 this time
