What Is Dynamic Range and Why Do Photographers Care About It?

What Is Dynamic Range and Why Do Photographers Care About It?

Dynamic range is one of the most fundamental properties of a camera sensor and one of the leading specs photographers are concerned about these days. What is it, though, and why is it so important? This great video tutorial will introduce you to the concept and show you its practical consequences on your images. 

Coming to you from Apalapse, this helpful video will show you the ins and outs of dynamic range and why it matters to photographers. Simply put, dynamic range defines just how wide the gap is between the darkest and lightest parts of a scene. In the context of a camera sensor, it defines how wide a gap that sensor can capture in a single exposure. The reason this is so important is because a lot of scenes you will encounter (particularly landscape scenes) will have a dynamic range that exceeds that of even the most modern cameras, and you will have to employ a number of techniques to get around that or simply accept the limitations it will impose on the image. As such, having a functional understanding of how it works and how it affects your photos is quite important. Check out the video above for the full rundown.

Giving My Audience a Reason to Care as a Photographer

Giving My Audience a Reason to Care as a Photographer

Giving My Audience a Reason to Care as a Photographer 1

When competing in an attention economy, giving your audience a reason to stay rather than scroll onwards is one of the most essential paths to retaining that attention.

Offering value in some way that makes people want to see the next slide, turn the next page, or even buy a print or publication to see a completed work can be a difficult balancing act — too much value and there is no incentive to continue investing in that work, not enough and people will lose interest.

Currently, this has been the priority at the front of my mind when working on my projects, in shooting, sequencing, publishing, and marketing. I want to give those who choose to spend their money and time viewing my work something more than a collection of images. I want there to be a reason to stay invested in a project, a flow that demands the next page turn with a real narrative unfolding across the publication.

Giving My Audience a Reason to Care as a Photographer 2

Truly outstanding individual photographs in any genre can be found on any of the current sharing platforms and forums, but it isn’t enough for me to allow this to be the way I present work when I have something to say. When I want someone to care about a character or cause it isn’t enough to me to have one transcendent image that says everything, I’d prefer to do a deep dive and really spend time with my audience unpacking these ideas from my perspective.

Looking back on my time when street photography was my main focus — now it has evolved into structured, long term documentary work — I struggle to find this core driving motivation of work that has anything to make an audience truly care about the story being told. This is mainly because they are one-offs, or sequences based on themes and locations rather than a narrative involving who, what, when, where, why, featuring a beginning, middle, and end.

For all the genuinely fantastic images that fit the street photography genre, very few, especially in the new wave style, seem to be actually satisfying in a narrative sense.

Giving My Audience a Reason to Care as a Photographer 3

There is little reason to care about a street photograph if all it does is pose questions, offering no resolution. Who are these interesting or mysterious characters? What are their stories? What can we learn from these ideas, often so beautifully presented? It’s all build-up, no payoff; all joke, no punch line. Little continuity, just themes, and iterations. This isn’t inherently a bad thing, but when looking for value in even the best examples of contemporary new wave street photography, it is fleeting at best.

There’s a chance that forty years from now there will be a nostalgic and historic value, which is what we find today in the work made in the 70s/80s, but that will only be true for a fraction of work being produced today; and again in reference to the new wave approach, will we really look back on silhouettes walking through beams of light with a nostalgic twinge? Will “timeless” work really be useful to history when it’s been made not as a documentary of the present but in the mindset of existing nostalgia?

A street photographers “legend” can seem to be about themselves, their personality and context, rather than about the content of their images, the stories of their subjects, who are preserved as caricatures, very little grounding them to anything other than their likeness (those who aren’t silhouettes, who are grounded to, and represent almost exclusively emptiness for the audience to project onto).

Characters and visceral emotion: these connect an audience to an image, not geometry and light, the way some talk about geometry in photography you’d think they were mathematicians! Searching for shapes, for light, these are decisions made from photo to photo, which fit around a true emotional core, not something that should define a career. Story and narrative arcs are the glues that connect one image to the next and are what make your audience want to turn to the next page.

If humanism and the exploration of humanity through photographic anthropology is genuinely what drives your work then I truly believe that you will find the most reward in finding answers and realizations to personal struggles through your own observations rather than to pose ambiguous questions, set atop aesthetic pedestals. Maybe that’s enough for some, but not for me. I spent too long chasing images that ask questions rather than ones that offer personal resolution, and I see a lot of the time spent on those early street photographs to have been wasted, aside from less than a handful of gems, just a lot of regret and wasted potential.

A few humanist photographers worth studying with cohesive bodies of work presented in a way that offers genuine value in every page turn are Jim Mortram, Tish Murtha, Sagar Kharecha, and John Bolloten, all UK based documentarians.

Like these photographers, I do my best to extend the offer of value to my audience beyond the confines of single images and into the way I prepare my projects in print. I want people to engage and invest in the story I’m telling so that every page turn presents them with new information and keeps them moving through my sequence, not just hitting them with constantly context-less but pretty iconography.

Giving My Audience a Reason to Care as a Photographer 4

If pages aren’t harmonious, if there’s no conversation between spreads or if it’s simply presenting individual images with no relation other than the same photographer made them, then there’s no real reason for a reader to turn to the next. If a prose book tried to tell a coherent story by putting disjointed sentences sharing no connective tissue with one another, jumping from idea to idea with every turn of the page then unless there’s a strong conclusion to tie this gimmick together it would not be particularly compelling — it would be a confusing, incoherent mess. Where this comparison may work is in an anthology book of individual poetry or shorts, where each page is self-contained.

Translating this idea to photographs allows something like a box of prints to be an effective and powerful way of showcasing photographs, but as soon as you stitch those into binding they are permanently sequenced; if done randomly without intentionality for a flow then it reverts to that random, disjointed, motivation less experience for an audience.

Giving My Audience a Reason to Care as a Photographer 5

Working on my publications once I’ve curated the soul of the project the rest of my time is spent weaving my images into each other, composing new “complete” pieces across spreads of two or more pages, so that everything works together and keeps the eye moving constantly in the direction I want to guide my viewer. In the same way, movies work with beats, the best examples being ones that hit the right emotional beats at the same time as the narrative ones whether they involve silent contemplation or explosive energy, I want to lead into an emotionally resonant moment at the same time that my page designs line up and offer a moment of clarity and realization.

Whether or not my audience does in fact care about the way my work is presented to them in this way is down to what they end up bringing to the process. I’m open to understanding that even though I invest a lot into presenting ideas in a way that makes sense to me, it may not land with everyone in that way.

Having said that, I think it’s still important that I do my best to offer value in some way rather than thoughtlessly generating content that relies entirely on what people bring to it when viewing. Even a modicum of artistic direction can go a long way, and the feedback I’ve had from those for whom my work does land is a testament to this – I value that input far more than social media platitudes.

Giving My Audience a Reason to Care as a Photographer 6

Where some may find value in the social media grind, I think that it contributes to one of the least caring attitudes to consuming photographs. The number chasing aspect makes the “wrong” part of things competitive, instead of looking at who makes the best, it’s about who can gather the most following regardless of the actual results. Ultimately, all of the social media game is for the sake of work that is scrolled by in seconds, very rarely making any kind of impact at all.

Giving My Audience a Reason to Care as a Photographer 7

I feel the opposite of competition can be not only possible but effective and positive. When I collaborate on publications and print set sales with my collective, it is without individual ego. The summation of our work would not exist without all our efforts. When I put out an individual publication or print sale, I don’t think it’s in competition with anyone else because no one else is truly offering the same product.

Of course, two darkroom printers can each sell their prints without stepping on the toes of the other, because the work itself is different and will appeal to different people. If you look beyond the fact that it’s a piece of paper or pages, the actual nature of the product becomes clear. Just because I sell a book with pages doesn’t mean I’m competing with the Tolkein estate just because they also sell book publications.

If someone likes what a photographer is putting out then they can support that photographer, and if they like the work of two photographers then that’s even better. It simply isn’t a zero-sum game, but that is how social media can make things seem, a twisted landscape to operate within.

Giving My Audience a Reason to Care as a Photographer 8

Once you have my zine, book, or print in hand, I am no longer competing for your attention — something not very possible online, undivided attention. It wasn’t too long ago that you could watch a video online with no adverts, now there are minutes of un-skippable ones, not just before the video but interspersed inside the content, literally dividing the attention.

I am sure we are not too far away from having to see a slide or two of adverts on a carousel before we are able to get to the actual image content we are after. Not yet mainstream, but not difficult to imagine.

If your photographic identity is tied to that icon in your phone then you will not escape from leaning towards producing meaningless work to feed the serotonin trap. Come up with something vaguely pretty and bold so it fills the phone screen and the little numbers will give you the brain feel-good reward, and you’ll spend your whole career or time as a hobbyist chasing that high instead of the deeper, harder earned ones which only come from challenging yourself, your process, and your audience.

Giving My Audience a Reason to Care as a Photographer 9

Just because my photographs are not something that exist in a meaningful way digitally, on digital spaces, doesn’t mean that they are unavailable. It’s not a return to a bygone time, or moving backward, or refusing to progress.

Look at the language we use when people remove themselves from social media entirely, like “unplug”, or “disconnect.” It’s not some grand ceremonial exiting of society, it’s just using a device slightly less. We offer all this grandiosity to platforms when we should be assigning it to ourselves.

My work exists in the present, physical now, not a transient space. Once you’ve swiped past a post, it usually ceases to exist at all. My work on walls, in collections, folders, shelves, binders, will continue to last if treated well. They don’t simply vanish into vaporware.

I think social media does have its place but not as a space to showcase powerful ideas, but rather to discuss them. When I put my handle out there and say follow me it’s not so that I can blind you with special work because I don’t want to waste the impact of an image with the first time you see it being on a screen, no matter how large, I want it to be on a page where I’ve made the decisions, the texture of the fibers, so you feel it as you see it, its own artifact.

Giving My Audience a Reason to Care as a Photographer 10

Instead, when I suggest that people follow my social feeds, it’s an invitation to be part of the community of people finding value here. Talk to me, send a message, engage in the comments: the social of social media, it’s not about the media but the social community it gathers in, from all over the world. Some great figures like Andy Adams are leading many to move to the Twitter platform which allows a much smoother conversational system than some photo sharing sites.

It’s why the direction of our collective New Exit Group’s presence on Instagram isn’t a highlight reel of our own work but somewhere we share our process, as well as a selection of work from people we’d like to draw attention to, in a way that pulls ideas together rather than single images one at a time. We rarely share individual pieces, but we instead use diptychs and slideshows so that we aren’t just talking amongst ourselves but showing that work can coexist in sequence harmoniously and collaboratively.

Of course, the things any of us may care about are entirely subjective. Some may not care for images showing people and their stories at all, some love nature so will respond better to a beautiful vista or still life of a leaf in a frozen puddle.

However, the way that work is presented in a cohesive way transcends documentary photography, so there is still something to be taken from these ideas, and true value can be found in bodies of work presented in a mindful way, leading your readers and audience to truly care about what you’re offering them.

Photographers Really Shouldn’t Care About These Things

Photographers Really Shouldn't Care About These Things

We all get caught up with various things in photography that we fixate over or just worry a bit too much about, but what should we really not be worrying about?

I have made pretty much every mistake when it comes to wasting my time in researching various aspects of photography or simply fixating on things that really don’t matter, scrimping and saving to buy something way out of my price range, only to realize that no one can tell the difference.

In this video, I talk about the main things that us lovely photographers often end up overly caring about that no one else outside of the online digital photography community really thinks about. I am sure the list could be far longer than what I managed to come up with, so please do let me know of anything that springs to mind in the comments below. 

My personal one is over-researching camera and lens purchases. I currently shoot with a mid-to-high-end level kit that I lost far too much sleep over and doesn’t really offer that much more over my previous setup (bar bragging rights). My current one is looking into overly expensive power packs that offer huge amounts of watts for my lamps at a very short flash duration, even though I haven’t photographed a moving subject in about eight years.

Care

Some of the best documentary photography has been done by people working within their own family or friendship groups. The have documented the illness, decline and death of parents, partners and friends, or the travails and recovery of people close to them battling with mental and physical illness.

I’m not one of them: too inhibited by the conventions, too worried about giving offence, sometimes too close. And always the feeling that to document is to intrude, especially with people who are reticent about being the centre of any sort of attention.

Some years ago, I made 6-weekly visits to an aunt who had become bedridden, and though fortunate enough to be able to pay for private care in her own home, spent several years in the process of dying – something that she had hoped she would do swiftly, possibly walking on Exmoor. First her body failed her, and then her mind. I took a few pictures that were not of her, including a non-portrait of the view from the window of her lounge, which was also her bedroom for several years.

But I never took pictures showing her decline directly, and sometimes this troubles me: is it some sort of moral or photographic failing on my part?

I think, possibly, not. What I can do with a camera is – despite appearances – pretty non-intrusive. The models I photograph are celebrating their existence by working as models, and are able to present themselves at their very best. They collude with me in portraying their beauty.

What does a family documentary series need, I wonder? Certainly, an ability to use a camera without much thought of the technical, but that’s true of most areas of photography. And often, the sort of rather confrontational image that is honest about decline and decay needs only the most basic of settings: Program mode will often do. Maybe on-camera flash is OK as well, as it is for happy family snaps.

Some sort of understanding with the subject, definitely sits at the top of the list. You can’t make these pictures without a deep engagement, without some sort of empathy, the willingness to let you own heart break. But there must also be steel, to recognise and capture the telling moment. It’s like photographing your child when they are hurt and crying… There is a risk that what you need to make the picture is also what destroys the relationship that underpins the picture…

Yet some people manage it… I would welcome insights, stories and suggestions. And, befitting my failures with this area, there are no images today.

Nvidia Announces New Graphics Cards: Should We Care?

Nvidia Announces New Graphics Cards: Should We Care?

If you’ve read any tech journalism over the last day or two, you’re probably sick of seeing the words Nvidia and 3000 series designations. It’s no question Nvidia has created some impressive technology, but is it actually going to change anything for photo and video editing? The answer might just surprise you.

First, let’s talk briefly about the cards. Nvidia announced the RTX 3090, RTX 3080, and RTX 3070. These GPUs are their latest generation, featuring a host of performance improvements over the older architectures. All the usual upgrades are there, including more cores, faster memory, and the newest connectors. Even at the “lower” end of the stack, the RTX 3070 is supposedly faster than their previous flagship RTX 2080Ti.Nvidia Announces New Graphics Cards: Should We Care? 11

There’s no question that these cards are going to offer a significant performance improvement to Nvidia’s core market of gamers and machine-learning researchers. For photo and video editing use, however, are these even going to be worth the upgrade? That question is a lot more difficult to answer owing to the highly-fragmented nature of GPU acceleration in professional programs.

Fortunately, over the last couple of years, Adobe and other software makers have added a number of GPU accelerated features to their programs. This has meant faster workflows, most notably where processes that used to have to render are now drawn in near real time — just look at scrubby zoom in Photoshop. To better understand how a faster GPU, let’s take a look at what workloads are accelerated on a per program basis.

Photoshop

For Photoshop the following tools either require a GPU or are dramatically accelerated by the presence of one:

  • Perspective Warp
  • Scrubby zoom
  • Smooth brush resizing
  • Lens blur
  • Camera Raw
  • Resizing with the preserve details option
  • Select Focus
  • Blur Gallery: Field Blur, Iris Blur, Tilt-Shift, Path Blur, Spin Blur
  • Smart Sharpen
  • Select and Mask

Looking at that list, I’m not seeing anything that is currently a pain point in my workflow. Probably the biggest benefit comes with the select and mask flow, where some larger images can chug on my 2070, although I wouldn’t upgrade just for that. I’d argue that any reasonable modern GPU is already plenty sufficient for Photoshop.

Lightroom

In Lightroom, the many of the adjustments are GPU accelerated, including basic adjustments and the tone curve, HSL, split toning, detail, and other panels in the develop module. Notably, the adjustment brush, loading raw images, generating previews, and a host of other time consuming tasks are not GPU accelerated. Also, some more niche but time intensive processes like HDR and panorama generation are not GPU accelerated.

Like many aspects of Lightroom, the situation is messy. GPU acceleration itself is buggy, with users reporting a variety of issues. Enabling GPU support on too weak of a card for the files can counterintuitively make things slower than no GPU acceleration at all. There’s the additional caveat of screen resolution, with GPU acceleration making more of a difference at higher resolutions. I didn’t really see an impact until I went to a 4K monitor, for example.

For Lightroom, the choice of GPU is highly dependent on your existing gear. If you have a high resolution monitor and an older, slower GPU, a new card could make a large difference to not only speed but stability. If instead you’re using a relatively new card with updated drivers, your money can be put towards better storage or a CPU upgrade, which should provide a more significant boost to the user experience.

Video Editing

The video editing world has been enjoying GPU accelerated effects and transitions for a while. Blending, scaling, some effects like color balance, and transitions like cross dissolves can all get a boost. Notably Lumetri looks all play well with GPU acceleration in my experience. Since the complexity of different video projects can range far more widely than photos (1080p vs 4K, heavy effects use vs cutting together some clips), you’ll have to take a look at your workflow. When you edit a project, have a GPU monitoring program up and check things like VRAM usage and utilization to see if you’ve maxed out your current gear. One important note is that while these new cards support AV1 decoding, the hardware support for fast AV1 encoding still isn’t there.

Other Programs

Interestingly, a number of more niche programs offer better GPU benefits than the industry titans. Specialty programs like panorama stitching and focus stacking often support OpenCL acceleration, meaning these cards could give you a big improvement to processing times. Additionally, photogrammetry users will appreciate the larger VRAM amounts on offer.

If you work with CGI programs that support GPU acceleration, these cards should be very appealing. A large bump to VRAM that was previously unavailable below Quardro level cards combined with a claimed significant boost to performance could offer significant benefits. The analysis of these specialty programs is beyond the scope of this piece, but if you find yourself compositing CG imagery with your photos or videos, keep an eye on program specific benchmarks.

Beyond Speed Improvements

Looking beyond just the raw speed improvements, it’s important to consider some of the features of the cards and what they mean for the visual industries. The first is the continued expansion of AI powered features, implemented in products like NVIDIA Broadcast. The software takes input from regular webcams and mics, then performs software magic to drastically improve the quality and add features. For instance, they demoed high quality real-time background removal without a green screen, and the existing RTX audio processing delivers amazing background noise reduction, capable of even filtering out a hairdryer along vocals.

Last but not least is the RTX’s namesake feature of ray tracing. First introduced on the 2000 series cards as a glorified tech demo, it seems the hardware has made it to the point of usability. Their demo, with hundreds of lights and a complex scene featuring one hundred million polygons, ran at 1440P at a reasonable frame rate. With these quality improvements to ray tracing, are more clients going to opt for a virtual photo shoot? Ikea already generates most of the imagery for their catalogs via CGI, compared to traditional photography.

Conclusion

If you’ve been sitting on the sidelines for the last few GPU generations, I don’t blame you. Between rising prices and diminishing performance improvements, there hasn’t been much of a reason to upgrade. The messy state of hardware acceleration for the programs used has made it an even tougher sell. In past articles covering hardware, I’ve mentioned a set of priorities for many users: a dollar spent on an NVME SSD or faster CPU typically offers more benefits than a GPU, and it seems that still hasn’t changed. If however, you’ve already maxed out your computer in these other areas and are looking to wring out more performance, or your specialty workflow benefits from the discussed improvements, Nvidia’s 3000 series cards should be at the top of your list.
