This question is big as it’s equally related to exposure, development and printing at the same time… Thanks everyone for sharing opinions and experiences!
How far do you pull film for direct sunlight?
Let’s think of ASA400 film: it’s often used at 320-200 for common soft overcast light (real film speed, some say), and if –very different case– we need to pull film for sunlight contrast control, we expose it even more generously, and cut development to keep highlights safe. In the case of direct sunlight scenes, if we prefer shadows with distinct subjects -in a natural look- we commonly pull 1-2 stops from box speed: so, more light, and a shorter development…
But what if we need more “open” shadows? If sunbeams are hitting white walls / white floor, surrounding shadows are filled a little, but if walls and floor are darker, well, as there’s less / no bounced light, we need to expose film for even more light if we want to clearly show a subject that’s in the shadows… So here’s the complex question:
Have you found any push/pull/multigrade filter scheme that’s common to the films you use? Something like saying “I prefer to underexpose X stops and extend development (push) for most of my photographs because they come from dull light (overcast days) and I find myself using filter #Y for those negatives; but when there’s direct sun and I need very clean shadows, I overexpose Z stops from box speed and cut development accordingly (pull), and I like to print those pulled negatives using filter #A…”
This question involves the whole (technical, at least) photographic process, but my opinion is, as the sun is a relatively stable source of light when there’s open sky, there should be some agreement about how to pull for clear shadows, and the optimal multigrade filter(s) to use in that case…
So, how far do you pull for direct sunlight when shadows are important, and which multigrade filters do you commonly use for printing those pulled negatives?
And which filters do you use when you print pushed negatives?
Hi Paul,Have you found any push/pull/multigrade filter scheme that’s common to the films you use?

Yeah it's called the Zone System. If you have not read about or used the Zone System you might want to give it a try, or Phil Davis's Beyond the Zone System. The concept is basic, meter for the shadows and develop for the highlights. The ZS was designed for sheet film, but can be adapted for roll film. Your concept of pulling film is adjusting the development time on what AA termed -N development to lower contrast, or extends development +N to increase contrast.
So nobody around here using different ASA or EI with the same film, depending on scene contrast? I was taught to...
Hi Lachlan,The variance is drastically smaller if you are keying off your shadows like you should with a negative film. As others have said, go and take a look at Phil Davis' BTZS work, it's not perfect, but it is a good introduction to sensitometry & better approaches to metering. I'd like to reiterate that with today's papers it is possible to expose a roll of film sufficiently for good shadows, develop for not over dense highlights & still land with printable negatives between 00 & 5 from a wide variety of subject contrasts on one roll. If you work with a narrower range of subject contrasts, there is no reason not to refine your exposure & processing to land on G2 or G3. For the subjects I photograph & the quality of light I prefer, my process is now refined enough to land a core exposure on G2-3, with other filters used where needed to define details or burn-in where necessary. It isn't hard to do & the hours spent talking about it & theorising about what various 'gurus' have blethered about could be better spent exposing a few rolls of film & getting your processes under control.
Hi Paul,
Yes... In the 90's I bought Adams' 3 books for the first time: I read them before they were translated to Spanish, and also edge of darkness, cookbook, post exposure, etc., all of them common in Europe while I cursed my career in photography... I've pushed and pulled since, nearly two decades ago.
I'd recommend those who have not done it: pick a direct sun scene and place inside it 2 identical cards with levels of gray from black to white, one in pure sunlight and the other one in pure shadow, and test a few levels of overexposure and a few levels of underdevelopment applied to identical strips (bracketing)... Would you spot meter for shadow detail (ZIII, close 2 stops) the grays card un the sun, or the one in the shadows... I'm afraid none of both options offer the best exposure for sunny scenes' negatives if we need to show subjects in both light and shades...
Hi Lachlan,
I think it's me who shot the rolls both for real photography and for testing... Have you? From your words, it seems you have not, or maybe you should take a new look to your direct sun / pulling tests... I know what I know, and b&w film is not an absolute media, but a relative one, a flexible one... It has no fix ASA: a good photographer can make it work at different exposure indexes. And that's done because that's the way to make a negative able to get the most out of the printing stage.
