As the name of the filter alludes to, these lens filters do indeed lower the overall contrast of a shot. To clarify what that means in relation to photography; these filters will reduce the darkness of the shadows by allowing light to bleed into them from surrounding highlights.

The images above show you exactly what a low contrast filter does. For context, this is a black piece of velvet in front of a spotlight.
The images above show you exactly what a low contrast filter does. For context, this is a black piece of velvet in front of a softbox.

From the example images above, you should get a very good idea of what the low contrast filters do. Both of these example images use exactly the same camera settings and you’re seeing the straight-out-of-camera results. So, although I shot them with the same settings, there’s a difference. The image with the low contrast filter clearly has a certain subtle glow or haze effect.

Now that we’ve established what they technically do, let’s look at how low contrast filters actually translate into practical uses.

Low Contrast Filters – Past to Present

Historically, lens filters were always far more popular than they are now. The obvious reason for this decline is thanks to the proliferation of post-production techniques. Also, there are many options and flexibility that working on images after they’ve been captured offers you.

Years ago, photographers often used low contrast filters to give skin a certain ‘glow’ and flatter some skin imperfections. Remember, this was a time before ‘retouching’. Anything that softened or hid those minor lumps and bumps in-camera was extremely useful.

But low contrast filters are seemingly making a comeback. And they’re popular for professional imaging as well as among hobbyists. It’s because today’s cameras and lenses are simply ‘too sharp’ for some projects. For example, motion picture, broadcast industries, and TV still use lens filters a lot. The low contrast filters find their spot in period pieces where the razor-sharp images of modern cameras simply feel out of place. Take historical dramas for example.

Low Contrast Filters in Action on the Screen

The Crown

Cinematographer Adriano Goldman spoke about his particular visual look for the hugely successful Netflix show The Crown.

The show uses the Sony F55, Cooke Panchros and, often, Tiffen Glimmer Glass.

-Adriano Goldman

Pay close attention to how bright those shadows are where the curtains meet the window. Now imagine how dark those darker areas would be with no low contrast filter in place. They’d be extremely dark and we’d lose separation and depth with the subject.

Many shooters will often tell you how unbelievably sharp their lenses are, and ‘unbelievably’ sharp is the right verb here. Many lenses are, indeed, ‘too’ sharp and clear for some projects. So, Goldman uses the Tiffen low contrast glass filter for beautiful effects in the Crown series. For those unfamiliar with the filter, here’s how Tiffen company describes what their Glimmer Glass does.

Peaky Blinders

Another example of a period piece using low contrast filters ‘in-camera’ during shooting is the gangster epic show Peaky Blinders. Those familiar with the show will no doubt be aware that this is polar opposite show to ‘The Crown’. However, the atmosphere and depth a low contrast filter can add to visual storytelling is universal.

Director of Photography Si Bell goes on to speak about the look of the show and what they were keen to achieve.

A Tiffen 1/4 black satin filter was deployed most of the time with NDs and rotating polarisers just to take the shine and reflections off certain things.

-Si Bell

It’s worth bearing in mind that many of these dramas are set in areas with multiple points of light. Many of Peaky Blinders scenes are set in bar scenes and very dark rooms with extremely bright spots of light around them. Occasionally, there are even bare candlelight in shot. Filmmakers need to take care to give those lights a warm glow without them being too overpowering. Look at the spot of light behind the head here. See how it appears to have a warm glow and isn’t burning out to pure white?

Bell mentions the use of a Tiffen ‘Black Satin Filter’. Not familiar with that filter? Here’s what Tiffen says it does.

the resurgence of traditional camera filters in modern television

There are many, many more examples of this in modern television. If you were so inclined, you could simply Google ‘insert TV show name + camera setup’. It would astound you to see how many shows actually use some form of low contrast filter in front of a lens.

I had a hunch that the Crown and Peaky Blinders used them, Googled it and boom, they did. Trust me, the list of modern cinematographers and directors of photography using these filters on their lenses is huge. In fact, it’s possibly more common than ever before and that is in part due to the rise of incredibly sharp digital camera and lens technology.

It’s worth noting here that many of these shows will often introduce artificial atmospheres to their sets. Among other things, it includes smoke and haze/fog. While they produce a very similar look to the blacks as the low contrast filters, the haze and smoke are far harder to control and it doesn’t help the highlight areas.

Many of these media productions want huge files for 8K televisions and theatre screens. However, many cinematographers in the early 2000s were hesitant to switch away from film. According to them, the digital options lacked a certain character and richness. These low contrast lens filters, along with a host of other ‘in-camera’ filters, can take an edge off a heavily digital look that is often far more appealing to audiences. And let me further cement this point. I also got reliable information that Tom Cruise refused to be shot on the more modern digital cameras as they were too unflattering.

Low Contrast Filters in Photography

Okay, I’ve shared a couple of examples of the use of low contrast filters in pop culture. Now you should be a little more receptive to the idea of actually using an in-camera technique that involves lens filters yourself. If shows like ‘The Crown’ or ‘Peaky Blinders’, with seemingly have infinite budget, are using lens techniques over post-pro hacks… Maybe there’s something to them.

As I mentioned at the top, photographers have been using low contrast filters forever. In fact, it was even before cinema did. However, their popularity has waned, especially in portraits. Of course, there’s still a market for them, and any self-respecting landscape shooters would never leave home without one.

Imagine you’re a landscape shooter and you’ve set up your shot ready for that perfect sunset. The sun dips down low and now everything is heavily silhouetted with that big hot-light in the sky behind that gnarly old tree you wanted to photograph. Sadly you can’t just whip out a spare fill light to pop some light in that deep shadow, so you can either go for the silhouette shot, or you can give your raw file some extra detail in the shadows by popping a low-contrast filter on the lens. The filter will scatter just enough light into the shadows thereby giving you a little extra detail in those shadows where you previously had none.

Seems an obvious solution, but portrait shooters sorely overlook this basic principle. I so often see some heavily backlit shots where the highlights are so horrendously blown out! this Is because the photographer has increased the exposure to see detail in the foreground shadows. But as we also previously discussed, this is actually a modern problem.

Is your lens too good?

This is clearly subjective, but hear me out. Years ago, lenses were good, but they weren’t quite as crystal clear as they are today. As a result, some older or even vintage lenses have a sort of low-contrast filter built into them. Their glass naturally scatters light that enters them and we see some of the tell-tale signs. Check for halos and glowing edges, both associated with some of the modern low-contrast filter shots.

There is NO low contrast filter being used in either of these shots. But, you can clearly see that an older Nikon lens from the 70’s had a certain ‘glow’ to it. Fast forward 20 years and we’ve all but eradicated all trace of that glow today.

You should be able to see what I mean from the shots above. A modern lens provides a very clean and clear edge between light and dark and the shadows are all but jet black throughout the shot. For many of us, that’s what we want, but there’s still a place for that older lens look too. To me it feels a little more organic and truth be told, it actually feels a little more ‘real’.

Technically Perfect, But Not Realistic

Most lens technology is now so good that it actually far surpasses our own eye quality. When I look at the sun or a bright light, there is a glow around it… do I need to upgrade to the pro version?! The older lenses and the more modern low-contrast filter ‘look’ actually feels more reminiscent to us as this is how we would visually see the world in real life! This is one of the key reasons we see it so much in cinema and T.V.

Examples of Low Contrast Filters in Action

Let’s be honest, I’ve been pretty defensive up until this point. If you’ve read this far then you’ll undoubtedly be surprised that I’ve firstly not tried to sell you anything yet, but secondly, I’ve yet to show you any results of low-contrast filters in action with portraits. The reason for this is that the vast majority of photographers simply write off lens filters as ‘Photoshop for old people’.

Yes, there are lens filters that can be replaced by Photoshop actions and filters if you want, but I honestly believe there is no short-cut or Photoshop hack for what low-contrast filters do.

Can’t I just reduce the contrast in Photoshop though?

No. The low contrast filter is doing far more than simply ‘lowering the contrast’. With a lens filter like this, it’s actually scattering the light as it enters the lens and as a result, you’ll have far more detail to work within supremely contrasty images.

Sounds good. I’ll use it for every shot!

No. Please do not use it for every shot, or even most of your shots for that matter. The low contrast filter has a very specific use and that’s often for heavily backlit images where the light or multiple lights is set against far darker subjects like silhouettes or where we have a lot of strong directional light just out of shot pointed towards to the camera.

Let’s look at some examples

Example 1 – Strobe just out of shot pointed at the camera

This example has no bare bulb or direct highlight in shot, but it does have a blue light just out of shot to camera right pointed over the subject’s shoulder, plus it had a red bulb just out of shot in that lampshade.

Both of these shots were processed in the same way, but it should be clear to see the very significant difference between the two shots. In the image with the low contrast filter, we have more detail in the shadows and although we’ve chosen to not pull out too much of that detail (look at the fabric on the jacket lapel for example), it’s there.

Also, look again at the highlights. At the very top of the frame where the illumination is brightest in the image with the no low contrast filter, the lamp with a red bulb has lost nearly all of its colour in the brightest areas. Compare that to the shot with the filter and you see not only more detail but a lot more colour too.

Example 2 – Heavily back-lit by natural light

This image sees me using a 3/4 power Low Contrast LEE Filter on the lens

Here we have a mix of strobe and natural light. It’s worth noting that the majority of this set is lit by that very bright natural light window to camera right. I’d also like you to consider how much light is appearing in the shadows of this room. Look at the corners and the area around the window. I have no light pointed at that due to absurdly limited space in this room, so instead, I opted to use a low contrast filter on the lens to ‘simulate’ the effect of light being in the dark areas.

…and because I know there’s already a millennial in comments typing about how they’re ‘entitled’ to see the raw file! Here’s a couple of test shots below where I experimented with the low contrast filter on and off the lens.

The left image shows the raw, straight out of camera file with NO low contrast filter. On the right we have the raw, straight out of camera shot with the LEE Low contrast filter on the lens.

Again, it should be extremely clear to see the difference between these shots and just how much that low contrast filter is doing to the shadows in the image. You have to remember that this filter is giving you options. If you want to pump the contrast up a little later on in post then you can do. But me not using a low contrast filter here would have been detrimental to the shadow detail in the final shot.

Example 3 – Strong strobe backlight behind the subject

This particular setup was built around the fact that I knew I wanted to use a low contrast filter on my lens. Behind the subject, we have a large softbox that covers the entirety of the background. This understandably kicks a lot of light directly into the camera and I knew that if I used a low contrast filter on the lens here, it would create this slightly hazy effect that nicely mimicked the hazy plant effect we had behind her.

If you’re interested in learning more about this particular setup in detail, it’s fully explaining here Imitating Hazy Backgrounds with Diffusion Gels

Are you curious to see what the low contrast filter is actually doing? Take a look at the side by side below, with and without the filter.

On the left you have a shot with the low contrast filter over the lens. On the right, you have the shot with nothing in front of the lens. Both of these shots are raws, straight out of camera with zero adjustments.

You get the idea now?

With these three examples, you should now have a pretty strong idea of exactly what these low contrast filters do. Bottom line; they aren’t for everyday use. In fact, these filters will not even work in every situation. For example, if you have zero light coming straight into the lens or no bright highlights in the shot, you could have the low contrast filter on the lens and not even know it. This is a very situational filter but it can have such a huge impact on your shots if you use it correctly.

The Low Contrast Filter I Use

I personally use a pack of Low Contrast filters from LEE Filters. The pack comes in a range of strengths from a 1/4, 1/2, 3/4 and 1. The number 1 offering the most dramatic effect. Truth be told, I’ve not used any of the other brand low contrast filters out there to compare and as you probably noticed from the start of the article when we looked at examples in TV shows, there’s a ton of them by other brands that seemingly do the same thing.

The LEE ones I have work for what I need, but if you want to dig into the low contrast filter options further, you’ll be looking at variations in how they deal with highlights, halation effect, glow, sharpness, diffusion and more. Trust me, the variances in low contrast filters is a full-time job in its own right. For more details on the ones I use, take a look on LEE’s site here LEE Low Contrast Filters.

I personally use the LEE Filters Low Contrast filter set. This includes filters of varying powers including 1/4, 1/2, 3/4, and 1.

I personally just hold mine in front of the lens with my hands for the shots that I need them for, but you can get a holder that will attach to any size lens you have. I personally prefer this method over the circular screw-on ones as I can switch lenses during a shoot without having to buy lens filters for each of them.

You can simply hold the filters in front of your lens with your free hand, or place them in a proper filter holder

Frequently Asked Questions

Is it blurry?

I can hear you now.

But do low contrast filters blur or soften my shot?

The reason I know you have that question is that I asked it too. Technically, I guess yes. Anything in front of your lens will potentially ‘soften’ your shot. I’ll be totally honest though, I can’t see it. Granted, these slightly more expensive ones from LEE family of filters are of exceptional quality. You get what you pay for. But from the tests I’ve done, these filters do not ‘blur’ the shot to reduce contrast. Take a look at the zoomed-in shot below to make your own judgments though.

Here we have a very zoomed-in crop of an image that had the low contrast filter in use. The eye looks pretty sharp to me.

I showed you this shot earlier in the article and this was one of the test images I took with the low contrast filter in place. You’ll notice that everything is still very much pin-sharp. Also, note that we have that very bunched up histogram in the top right of the frame. This is showing us that all the data is very much in the middle and this is what we’d expect to see from an image with less contrast.

Low Contrast or Diffusion?

Long-time followers of my work will no doubt know that I also regularly use another lens filter called a ‘diffusion filter’ aka ‘soft filter’. The low contrast filter is very different and you should not expect to simply use a diffusion filter in its place. Think of a diffusion filter causing a more focused area of flare. A low contrast filter will evenly spread the light over the entire scene compared to the more focused flare of the diffusion filter. With low contrast filters, you’ll get a small amount of controlled flare in the highlights.

Here we have there shots. One with no filter, one with the low contrast filter and one with the diffusion filter.

I’d be wary of using your diffusion filter as a replacement for the low contrast filter. You can see from the images above that the diffusion filter is far more aggressive. It has a brighter centre point next to the highlight and it drops off to shadow regions far quicker. Don’t get me wrong, diffusion filters have their place. But consider them for more of a ‘dreamy’ look. On the other hand, the low contrast will provide more of an ‘atmospheric’ look.

Closing Comments

Should you get a low-contrast filter?

The short version here is that this os one of those accessories definitely worth having. I recommend everyone has a low contrast filter if they can afford one. This goes doubly to the mirrorless users who have systems with their painfully sharp files. Yes, you may love the razor-sharp images where you can see the DNA in the pores of your subjects, but consider what your subjects and clients may also like to see as well. I personally think that although sharp images are fine, there are times where many creatives are trying to put a little more ‘soul’ and realism back into their shots.

Video games

For example, I could go into more detail on how the video games industry spends millions each year on developing purely artificial in-game lenses with bokeh, halos, fringing and diffusion in an attempt to make us feel more ‘immersed’ in a synthesised world. That entire industry strives to make their imagery look less artificial and I find it odd that as one art form struggles to trick us into being immersed with visual artefacts, another simultaneously strives to make things feel hyper-real by removing all trace of them.

The video games industry spends millions to make games more realistic. One common tool they employ to do this is by replicating visual artefacts in their games that we’re more familiar with seeing in real life (or that films have taught us are in ‘real-life’). We’ll skip the irony of adding bokeh to first-person shooters, but let’s assume we’re all wearing dirty glasses on the battlefield. -From left to right ‘Killzone’, ‘Black Ops 4’, ‘Battlefield 4’.

Films

Older readers may also recall the era when ‘Industrial Light and Magic’ specifically strived to create these ‘visual-effects’ in films like ‘Star Wars’ and ‘Close Encounters of the Third Kind.’ These are of course ‘styles’ and although JJ Abrams may have famously overdone the infamous ‘lens flare’ a little in his more modern work, the fact still remains that there’s huge scope to get away from this purely crystal-clean and perfect look the entire time.

‘Close Encounters of the Third Kind’ released in 1978 showcasing some very revolutionary lens flare effects at the time.
Fast forward 30 years: JJ Abrams gets a little overzealous in his famously heavy-handed lens flare effects in 2009’s ‘Star Trek’.

No, video games and movies are not photography. But, it’s always advisable to look outside of our own industry to see how others deal with similar aesthetics and what trends are emerging.

A New Generation

It’s also worth noting that we’re starting to see the first generation of photographers that are coming of age who have NEVER used a film camera before or have even seen one! Feel old yet?!

As with everything else, fashion and styles are often cyclical to new generations that come along behind us. I guarantee young people will fall on these old film ‘effects’ and claim them as new and original. And sure, they are new to them. I’m calling it here and now. However, don’t be surprised if there’s a comeback of these ‘in-camera’ looks in photography. We’re likely to see young photographers mimic styles they’ve noticed in gaming and cinema.

Lens filters like low contrast filters are a tool and unlike JJ, we should use them sparingly. But in the right situation, these low contrast filters can do what no Photoshop filter can do. So, we need to have them ready to hand when the situation presents itself.

FAQ

Why use a low-contrast filter?

Low-contrast filters offer a softer, more ethereal aesthetic by reducing the harsh contrast between highlights and shadows. This allows photographers to recover detail in dark areas and create a more “realistic” look that mimics natural light perception. Additionally, the filter’s subtle “glow” can emulate the vintage feel of film photography, appealing to a younger generation of photographers influenced by gaming and cinema styles.

What does a low-contrast filter do?

Low-contrast filters soften images by diffusing light entering the lens, reducing the stark contrast between highlights and shadows. This reveals details in dark areas that would otherwise be lost, especially in backlit scenes. The filter’s subtle “haze” adds a more natural, film-like quality, mimicking how we perceive light and appealing to photographers seeking a softer aesthetic or a vintage look.

Do filters reduce image quality?

Low-contrast filters affect image quality. In some ways, they decrease image quality by technically softening the image with a slight “haze.” However, this softening can also be considered an artistic effect, creating a more pleasing or “realistic” look by reducing harsh contrast and revealing details in shadows.
