...So to pick up where I left off yesterday...I was railing with good-natured hyperbole about the general run of digital B&W. And on that point I need to begin by making a short digression to emphasize two points:
- I wasn't necessarily talking about the B&W of devoted practitioners—experts—many of whom know more about conversion than I do, and do splendid work (at least, they do the work they want to be doing).
- It's not a matter of film v. digital with one or the other being better or worse. I always used to gadfly at length about the normal run of poor printing with film on photo paper, too. Ninety-five percent of digital B&W might be crap (present company not included in that), but 95% of film B&W was crap. It's not a status thing we're on about here: it's about improving our perception, vision, taste, and technique, whichever medium we use.
...So then. As I mentioned, earlier this week I was agonizing over the Sony A7II vs. the A6500, and happened to run across this photo by a guy who shoots the A6500 and Sony 16–70mm ƒ/4 zoom, Paul Grubb. It perfectly illustrated what I was saying about modern digital tending to depress the middle values, so it provides an opportunity for discussion. Paul gave me his permission to use his picture for that, for which our thanks to him.
[For emphasis: Check out the photo on Flickr first.]
And I need to add—yet more qualifying, but it will come up in the comments otherwise—that there's nothing wrong with his picture or the way he's presented it, as I see it on my monitor. Insofar as it was deliberate I have utterly no problem with it; people own their own pictures and should do with them whatever they want to do. In critiquing, I'm not criticizing, necessarily. Paul for instance can take my comments and reject them all and that's perfectly okay with me. It's his picture.
But this should show what I mean by the way digital tends to shift the middle values downward:
Original on top, modified version on the bottom. They may look quite close to you at first, but before we go on, let your eyes go back and forth between specific areas of the two until you start to get a handle on the differences.
What I did was take a quick screenshot of a portion of Paul's picture—so I'm working with far less information than would be in the original file—and add an inverted S-curve to it:
At the risk of muddying the waters, I also added a touch of sepia color. But really, most of the effects you see are tonal.
Start with the man's and the woman's faces. Notice how the change in tone seems almost to change their expressions—in the top version their eyes are hooded, their features more sharp. The man looks a little angry, even, like he is scowling, and seems to have his mouth in a slightly different position—seems a bit more closed in the top version and a bit more open in the bottom picture, do you see that? In the top version, the bridge of the woman's nose is bright and her facial planes are emphasized.
Next look at her hair. In the top version it almost seems unnaturally streaked; in the bottom version it just looks like soft blonde hair.
I'm probably exaggerating just in order to put these things into words. But do you see how the top version feels just a little stormy, a little harsh? The bottom version just looks like people in a crowd enjoying themselves on an overcast day when the weather wasn't the best. This is the stuff interpretation is made of in black-and-white.
Note that this has nothing to do with "contrast" in the conventional understanding of it*. With the curve modification the black and white points stay in exactly the same places. It's merely the distribution of tones in between.
You might not agree that the change is an improvement, and that's okay, of course. The point I was trying to make is that the default conversion processing—across the tens if not hundreds of thousands of digital B&W representations I've looked at online, and far fewer (but still lots) in prints—tends to depress the middle values. In Paul's picture it's noticeable but moderate; sometimes it's much more extreme.
Flip over
I'd also encourage you to try to learn the trick of backing away from the technical observations and paying attention to the emotional representation. How do the expressions on faces look? What is the overall "feel" of what you're seeing? At the risk of more hyperbole—I'm emphasizing slight differences too much here—the top version imparts just a touch of dread and brooding, of severity, while the bottom version is more relaxed, more harmonious with the meaning of the scene we're looking at—a family strolling in a relaxed way in a crowded city.
It's a matter of learning to flip over from looking at the representation to looking at what's being represented.
The same mental trick can be learned with the light. We look at tone as a technical matter, and we see grays, contrasts, edges; but it's also possible to learn to look at it as light. Look at the representation and try to see the light of the day. What was the sky like? What time was it? To me anyway, the subtle change from the top version to the bottom version makes the light become real.
Please do grant me a bit of leeway here, in trying to put subtle visual effects into words! And also for the fact that the critical tones might appear too light or too dark on your monitor or device.
In any event, I think if you start looking for depressed midtones and learn how to recognize the "look," it will start to pop out at you, and you'll see it everywhere in online B&W.
Anyway, have a nice weekend! TOP will return on Monday, "same as it ever was." IF you happen to go shopping yourself and you're not in York, please start here!
Mike
(Thanks to Paul)
*[UPDATE: By "conventional understanding of it" I meant macro/overall/global contrast, i.e., pushing or pulling more or less information into or out of pure black or pure white. This short phrase has caused a lot of consternation in the comments. It's impossible to stop to define every term and qualify every phrase when writing a short, basic article. Please grant me that leeway I asked for.... —MJ]

Featured Comments from:
Ed Hawco (partial comment): "I'm following this with interest, because I do a bit of digital B&W and I come from a B&W film/print background. The standout item for me was the comparison of high end and low end. But I'm not 100% convinced on the middle values part. Mike, you said '...the way digital tends to shift the middle values downward.' My question—and I hope this doesn't sound flippant—is this: is it digital that shifts the middle values downward, or is it digital photographers who shift the middle values downward? By that I mean I wonder if it's primarily an aesthetic trend."
Mike replies: Various people have complained about this, including privately. But as I took some care to explain, it's not a film vs. digital status thing and I made no attempt to pinpoint the root causes. I'm just characterizing what I often see done, typically or usually. There's no time in a short, basic article to go into every ramification of every phrase.
I think your insight that it's partly an aesthetic trend is wise, however.
Paul Grubb: "Mike, thanks for the critique, they are always welcome, it's how I grow as a photographer by understanding how others view my photos. For me B&W post processing is one of the hardest, as pictures can change significantly with the smallest of tweaks to a lightroom slider. I do like the idea of the emotional approach to post production as it separates out some of the hard science and allows you to focus on what you are trying to portray. That said what I have learned is that the tone curve can totally transform the emotion of a photograph. Looking at the photo again, that guy's brow does trouble me, a little shiny and as you say a tad 'angry.' :-)
"Thanks again for the critique, it's given me some good food for thought and a desire to revisit this pic."
Michael: "Thanks a tremendous amount for this, Mike. (And thanks to Paul, whose photo from York reminds me vividly of the, ah, heightened experience when we first went there with two small children on a swarming Saturday and lost track of each other and the kids.) This illustration is a perfect teaching example and I will look for these effects much more carefully now that you have made the effort to tune my eye. I can certainly understand liking Paul's original, because it captures the moodiness of a winter's day in northern England. (It was on such a moody day that we misplaced each other and the kids.) But the raised mid-tones do, to my eye, reveal both a kinder side, and probably a more faithful interpretation, of people in in The Shambles (which, during the missing kids episode, seemed so ominous because it means the medieval slaughterhouses and butcher's shops of the city)."
Al C.: "Technically, your curve is not an 'S' (cyma recta), but a cyma reversa. Don't you always apply a cyma reversa in post, whether B&W or color? I do, for all the reasons you noted."
Henry Rinne: "I tend to agree with you about the basic B&W conversions in most software. I always find these defaults to be rather muddy and poorly defined. I have been using the Nik Silver Efex II for quite sometime and have created my own recipes for conversion that largely do what you suggest. I also like SEII's ability to indicate the ten step tonal range, which I have used to help understand the tonal relations in the image especially the mid and high tone values. I also agree that stepping back from the image and removing the technical aspect from your assessment is very important. After all it is an expressive work that should communicate something and not just enthrall another photographer because of its technical proficiency."
Lynn: "My starting point for B&W conversions of digital images is:
- What are the existing light conditions—is it bright/sunny with high natural contrast and deep shadows, is it overcast with a flatter tonal curve and more nuanced transitions from light to shade?
- What is the overall mood of the picture I visualize?
"When processing I prioritize maintaining the natural tonal relationships in 1. so the image retains a natural credibility rather than looking over-processed. Any tone re-mapping with curves to tweak the mood have to be done within the constraint of retaining credibility. The failure of most B&W conversions is when the natural tonal relationships in the picture for the existing lighting conditions are destroyed, and the image looks manipulated and fake. Most HDR (unless done subtly) falls into this category. The eyeball test is 'does this look credible?' Low contrast on a bright sunny day or high contrast in open shade or an overcast day usually fails the test."
Andrew: "This is an interesting discussion, with the crossing threads between technique, aesthetic, and technology.
"I recently went to see a Georgia O'Keeffe exhibit, and to provide context they included photography from her partner Alfred Stieglitz, and her friend Ansel Adams.
"I was very curious to see Stieglitz's work, as he is one of the giants in early American photography. But I was truly underwhelmed by the prints I saw there! Whether it was the medium, or the age of the prints, or his exposure, I noticed precisely this phenomenon you're talking about—the midtones were just wrong. Everything about the images seemed a bit too drab, and they felt underexposed, especially in contrast with the bright white matting of their frames.
"Perhaps I wouldn't have noticed it quite so acutely if I hadn't been able to juxtapose Stieglitz's work with Ansel Adams's. The Adams photos just had so much more depth and nuance in them—while there is no denying the talents of his eye, his mastery in exposure and printing was what truly stood out to me.
"A bit of a rambling story, especially placed against the very neat visual comparison you have up there, but all this to say that I wholeheartedly agree.
"Now, to load a roll of T-Max in my old Koni Omega 6x7. (Ugly camera, as your other post illustrates, but fantastic results that come out the other end....)"
William Schneider: "About strong opinions regarding 'right' and 'wrong' renderings of tonality...
"In 1995, I was hired to teach darkroom photography at the same time a Pulitzer Prize winning newspaper photographer was hired in our department. She preferred a much higher print contrast than I did. I had used large format film and the zone system extensively, and preferred that softer kind of rendering.
"To me, her B&W photos approached a kind of 'soot-and-chalk' appearance that Adams complained about. In pondering why, I thought of her experience. Newspaper printing destroyed subtle pictures, and couldn't reproduce all the shades of gray apparent in an original darkroom print. She preferred a print suitable for the inevitable shifting of tones when on press and strong graphics in the content. That's what she was used to. It was right for her, and she had a Pulitzer Prize.
"We still poke fun of each other about our printing preferences but we both understand that it's a decision born of taste, experience, and circumstances. It's not a 'right' or 'wrong' decision.
"By the way, I would have gone further than Mike did. But that's my preference, not his."
Mike replies: Something similar happened to Carl Weese and myself, but with the opposite result. When we (first?) met in the '90s, he was in D.C. to photograph some athletic events on the Mall. We argued spiritedly over print contrast, with me advocating softer, gentler contrast and he advocating stronger, livelier contrast. But some time later, we each realized our arguments had had an effect on the other—he had begun exploring soft, gentle contrast, and I had moved to "punch up" my printing style to make it stronger and more lively. :-)
Peter Wright: "This discussion had me pulling out my copy of Peter Turnley's French Kiss which was a TOP book offer some time back. Peter doesn't include technical details, but I believe that the pictures are split fairly evenly between film and digital using a film Leica and a digital M-Monochrom Leica respectively, each with a 35mm ƒ/1.4 lens. If you want to study good, consistent tonality across both mediums this is a great place to start. Most photographers would be able to tell which was which, but the tonality alone gives no clues. In my case, I also took advantage of the associated print offer, and bought one of the pictures which happened to be printed by Voja Mitrovic (who printed for Henry Cartier Bresson). Seeing examples like these has helped me know why and where to move that pesky tone curve! Time for another book/B&W print offer!"
Ken Tanaka: "Re 'I'd also encourage you to try to learn the trick of backing away from the technical observations and paying attention to the emotional representation.' That's actually the most important message here. Learning how to use color and tone to implicitly communicate from within an explicit scene should be the goal. Rightness can only be judged against communication intentions, not against technical standards."
Doug Thacker: "I think this suppression of the midtones in B&W photography pre-dates digital. I think it represents a change in the collective eye.
"When I got into photography as a high school student in the early 1970s, it didn't take long to realize I detested the middle gray of most black and white photography. To me, it looked bland and boring and old fashioned. Shortly after I learned to print, I started using a higher contrast paper and printing for deep, rich blacks, and luscious, pristine whites, with only enough tonality in-between to hold up both ends. I also wanted to know why art photography couldn't be shot in color, and proceeded to do just that.
"Life then intervened and I got sidetracked for a while, but when I next looked up, sometime in the '90s, I noticed color photography had gained wide acceptance in art, and lots of people were printing black and white the way I used to—lots of advertising and magazine photography reflected this trend, as well.
"So that's when I concluded that this must be a generational shift of some sort, a change in the collective eye. Maybe being inundated with advertising all our lives had something to do with it, who knows? Or maybe it was the influence of electronic media—bright colors and high contrast B&W being the visual equivalent of sugar and fat.
"Then digital came along and made a necessity of preference, if not a virtue, and here we are. Even still, I hate the way digital typically renders highlights, but this may be changing. I've noticed that some current cameras seem to retain info even in the brightest highlights, and no longer just fall off a cliff the way digital used to. These seem to be the ISO-invariant sensors, such as the Nikon D7200."
