I typically use B&W film (Ultrafine Xtreme) for overcast days, but have recently discovered the Velvia performs quite well and somehow squeezes out A LOT of color from subjects on an overcast day. The Velvia is only useful if I can use a tripod, though... so usually I go with the Ultrafine.
A lot of people are more particular about the differences in tonality for B&W than I am. That is probably because a lot of people around here (of whom I am jealous) print with enlargers. I have to use a scanner, so manipulating those curves is not difficult.
I mostly shoot black & white also. In diffuse lighting I’ll often use a film that’s likely to give me a hard negative in full sun like Foma 100, Retro 80s or Pan F. These are films I usually have to be pretty careful with when I develop them because the contrast can get away from me pretty quickly. In diffuse lighting these films are a lot more forgiving but still provide good contrast.
Recently I’ve experimented a little with pushing faster films in diffuse light; HP5, Ilford P4 Surveillance film or Orwo N74+ pushed to 1600 and, so far, I’m liking the results. I’m getting the pronounced grain and blocked shadows that I expect from a two-stop push but not the extreme contrast. I haven’t played that much with it yet, though.
Unfortunately, slower films render overcast situations better than faster films. My own experience is to use a RF 35 mm camera such as Leica, Contax or Canon. Even better, if only a single lens will suffice, is a Retina or Contessa with a leaf shutter. I can hold these cameras quite steady at 1/25 second. An SLR, either 35 or 120 is much more difficult, although a Rolleiflex TLR can be held pretty steady at slower speeds.
Decades ago I tried every developer available at Olden in NYC, but finally settled on Rodinal except for very fast films for sake of simplicity. I shoot at box speed.
Like you, I enjoy reading the contributions of those you mentioned, plus many more. Waiting to see how others handle low contrast, poor light situations. I usually begin my day by perusing the latest contributions. It’s great fun reading remarks by true enthusiasts.
Do members have access to OFFICIAL information published in the past by films and developers manufacturers (Kodak and Ilford brochures, etc...), explaining how to achieve more acutance by doing x and/or y in comparison to doing their standard recommended development? That was usual decades ago...
I'll call this one Question1... Of course all members are welcome to answer and also to post questions with or without numbers here...
Thank you all!
The simplest and most effective way to improve acutance is to get your negative to print on a hard grade (ideally 4+) by whatever means necessary. If you're working in flat-ish light, developing to a 'normal' contrast index (likely somewhere in the 0.55-0.6 range for a diffusion head) may be all you need to do. An unsharp mask is also an option & is vastly more effective than chopping and changing developers.
Hi Lachlan Young,
First, thank you very much for chiming in! I've read LOTS of your great posts for years...
I totally agree about making the right (soft enough) negative for good contrast printing... You're right: no better way to start where we need to...
And for condenser enlargers, targetting for galerie (3 is all that's left now...) or filter 3, works much better for soft light scenes than doing it for filter 2...
About Ilford or Kodak recommending more acute ways of development after stating their own standard development, using for improved acutance different dilutions and / or agitation, I've seen just one source: the oldish fp4 (not plus) technical datasheet... It would be nice to see something from Kodak, if it ever did exist...
Thanks again!
From what I've learnt in practice, I think the reason the manufacturers don't really recommend what might be perceived as 'higher acutance' developers today is because current films are engineered to use higher iodide content in the emulsions and higher solvency developers - which together allow for a better grain/ sharpness relationship (finer grain and better sharpness) - and that a lot of so-called high acutance developers do nothing other than make bigger grain, at the cost of fine detail definition - however, many people aren't enlarging enough or scanning with adequately competent kit for the differences to be clear. As for agitation intervals (avoid stand development), all I've found is it's a means to finesse the control of overall contrast (which will de-facto affect microcontrast by affecting which grade you land on - if you control for this, the real differences are vanishingly small). This is not to say that you shouldn't try something like dilute (1+2 or 1+3) D-76/ ID-11 or Perceptol & compare to stock or 1+1, or many other developers, just be aware that the quality of your process controls are going to probably have far more impact on your final results than most differences between developers and agitation regimes.
The other thing I've increasingly found is that aiming a negative for a grade or so softer than your final print makes for an overall better image (ie aim for G2, but final print at G3-3.5) - even if you need to use various techniques to print it well. Printing on the 'correct' grade may place the tones 'accurately', but 'accurate' and 'looks right' aren't the same.
All of them really interesting points! Thank you!
These days I'm starting to experiment with Microphen for well exposed film, not for pushing... It'll take me some time to try a few different films and dilutions... Basically Tri-x and HP5+ (with fp4+ I don't seek speed), but I don't know why Microphen is seldom used that way, nor why there's so little information around for a good daily use without underexposing... It has less solvent than D-76, and while it's known it's better to use stock solution for a 2-stop push, I guess it must work well at 1+1 and 1+2 for sharper grain and all the speed it can offer after giving the film enough light and lowering its solvent... No idea on agitation schemes and their impact on tone: I feel it "makes" from the start a controlled "push look", but I imagine that can be adequate for soft light and a slight expansion... Of course only in the darkroom are the answers hiding... Perhaps at box speed I could get a clean tone as if using half box speed with standard developers... Good for stopping down in the street without losing shadows... I know it's not a lot more speed, but I'd appreciate being able to set a system using the next smaller f-stop... Things really change regarding DOF, field curvature, etc...
Great post as usual! Have a nice day.
I may have misunderstood what you have said here Lachlan but I think you are saying that Xtol and DDX give as much of a speed boost as does Microphen but evolved later? If my deduction is correct about your conclusion then besides offering the same speed boost ( half a stop is generally claimed) does Xtol and DDX offer anything else that makes it a better developer overall?). As regards Microphen's speed boost being less well known - as a product I think it was generally much less well known outside of Ilford's core domestic/ export markets until the 1990's - and by then Kodak Xtol and Ilford's DDX were doing the same thing, but somewhat further along the same evolutionary branch.

I ask this because I recall on a forum called FADU that someone who frequented it and Photrio and who appeared to do a reasonably scientific experiment with a number of developers claimed that he had evidence that only Microphen gave true box speed i.e. 3200 with Ilford D3200
I am a long time user of Xtol but have since been tempted to see if Microphen really gives the true advertised speed (3200) with Ilford D3200
Thanks

DDX (and the DD replenished variant) and Xtol seem to be optimised variants on the theme of Microphen with better utilisation of the understanding between solvency and sharpness,
Thanks for the reply I'll try and have a look for his thread to see what he said a little more precisely .
pentaxuser
Do you know if in the case of microphen, making it less solvent helps for a bit more speed as it's said about other developers? Again, not for real pushing but for developing well exposed film... Once I read data on HCB and other masters using microphen (60's-70's?), and I guess they didn't push very much in general...
