When you walk into a camera store or look at an online photographic shop there are so many filters for black and white photography that you could buy. The problem is, which one?! What actually makes a good black and white photograph and how can I achieve that? Do you buy into a filter “system” or buy individual filters? The people in the store might or might not know which ones are right for your type of photography.

When I first started photography in the days of film (click this link to see the best black and white film for travel photography), I was so overwhelmed by the vast array of filters that I spent a lot of money on buying up as many as possible. My thinking behind this was that it would improve my photography. I am now older and marginally less stupid but I have learned from years of trial and error.

Here are some of our really essential filters for black and white and colour photography as well as our shameful ones!

There are 5 essential filters for black and white photography that every photographer should own. I’d like to show you them now and explain what each one does and why you need it. If you’ve got some time on your hands and want to know tips and geeky explanations on how to convert colour to black and white, then click that << link!

Using Polariser to darken the sky

The UV or Haze or Skylight Filter

The first filter I am going to recommend is one I always buy for any new lens I get. This filter has 2 main reasons to live on your lens.

Firstly: Protection – I can’t count the number of times I have “dinked” the front glass on my lenses.

Sometimes it’s as simple as a quick knock against my belt when carrying the camera. (We use awesome sling type straps that go across your body. Ally swears hers is the best thing ever and is attached to it like an umbilical cord. She uses a Ladies Black Rapid. I have a Sun Sniper.) I once scratched my Nikon lens coating when putting the lens cap back on the lens. Having  just finished photographing, the rain was about to bucket down, and I was in a hurry. This does not excuse my not having a protector UV filter on the lens.

A filter is also easier to clean than a lens element. I have even dipped mine in water to wash off salt or dust after photographing waves or deserts.

Pro Tip: When photographing in areas that really dirty up your lens (like sea spray) carry a spare filter and change filters when the first gets dirty. It’s faster than trying to clean a lens in an inhospitable environment.

Whenever I buy a new lens the very next thing I buy is a UV filter. $50 to $100 for a high quality filter that doesn’t seem to do much might seem extortionate but if it saves the very soft (and very expensive) lens coating from just one scratch it will be worth it.

Secondly: Sharper and more defined details in the background – A UV filter cuts out the UV light and cuts through the haze making distance objects seem clearer.  With film it is more important to use a UV filter because film is extremely sensitive to UV light. However, digital sensors are generally less sensitive to UV.

This filter works the same with both colour and black and white photography.

Lastly, the UV haze filter is not to be confused with the UV transmitting filter. This only allows ultraviolet light to pass through the lens and blocks out all the other visible light spectrum.

The graduated filter (Grad)

The graduated filter is the next one in the list, for this filters for black and white photography post. A graduated filter is a neutral density filter that gradually fades to clear. The reason for this is that most skies are darker than the land so the graduated filter darkens the sky but not the land. See more explanations on this with our exposure compensation post, and ‘why your camera lies to you’!

Round screw or system grad filter?

These filters come in either a round screw in version or as a “system” version where you attach a filter holder to the front of the lens and then slot in the square filter of choice. The advantage of this type of filter is that you can slide the filter up or down depending on the amount of darkening you require. The other advantage is you buy different size adaptor rings for the system types that means you don’t have to fork out for multiple filters, only new adaptor rings. Both types of filter allow you to spin them around.

Graduated filters for black & white film photography

The Grad filters come in various strengths of darkening. Buy some cheap ones to experiment with first before spending a lot on one.

In my young college days these Cokin filter systems were all the rage, and from my extensive Cokin system, the grad was used more than anything.

While this filter works just as well in colour photography as it does in black and white there are a few other grads that work in colour too. I used to use a tobacco (orange/brown) to get warmer low sun photographs or a blue/purple to get more interesting cloudy skies.

The Neutral density filter (ND)

One of our favourite creative filters for black and white photography is the Neutral Density filter. It reduces the amount of light coming through the lens thus giving you longer exposures that you are unable to get in bright light even with an ISO of 50.

Why would you want longer exposures?

It will capture movement rather than freezing it. This could be either water, people, vehicles, clouds or anything that moves. On water this produces an ethereal misty effect and with people it can produce water-like blurs. It is very effective if some people are moving and some totally still. We have used this filter a number of times for dramatic effect on water. See our post on how we got on (or not) when we first used our ND filter recently.

Just make sure you have a very sturdy tripod as it’s so easy to get a blurry image with even the smallest bit of camera shake during a 30 second exposure. See our tutorial on how to photograph with an ND filter.

This filter works just as well in colour as in black and white photography.

Single colour filters for Black and white film

Black and white film uses a full range of the visible colour spectrum to create a full range of tones on your black and white negative. What a single colour filter does is to stop some of those colours from reaching the film and thereby making that area darker. For example, the filter we need to use to darken the sky would be one that stops blue reaching the film. Yellow, orange and red colours are opposite blue and so do this very effectively. A blue filter would darken reds and make the blues appear lighter. See our post on how to darken skies for more details on single colour filters.

The Polarizing filter

There are 2 main uses for polarizing filters, reducing reflections and darkening skies.

Here is how it works. Light reflected from a non-metallic surface becomes polarized. A polarizing filter allows light to pass in only one direction. This allows us to reduce reflections on non-metallic objects.

Light from the sky is also polarized, so a polarizing filter will polarize the light and reduce how much light enters the camera. As a result this will make the sky dark in a photo.

Photograph taken without and with polarizing filter

A polarizer will darken down blue sky but not affect clouds. (The effect is most prevalent on the area of sky that is at 90 degrees from the sun – Look at the sun – carefully – and then the darkest sky will be at 90 degrees.) It will also reduce reflections which can make trees etc seem rather vivid in colour. To use the polarizer just turn the filter until the sky goes dark or the reflections disappear.

A few things to be aware of with polarizing filters

This polarizing filter technique will work with both film and digital, colour and black and white. In colour it also increases the saturation of many objects by reducing reflections.

There are 2 types of polarizer. A linear and a circular. A circular CPL polarizer is best for modern cameras as linear polarizers can affect exposure meters and autofocus adversely.

Before we look at what makes a good black and white photo let us first see why we want to create black and white photos. There are so many reasons why we would create a black and white over a colour image and here are just a few. It could be that we’re looking for a certain cool and modern minimalist style. We might be going for a traditional classic photography look. There might even be times when the colour is too overwhelming or awful that we feel the need to remove it. Whatever the reason we need to understand what makes a good black and white photo so that our images look amazing.

What can colour do that Black and white can’t?

Colour is a great mood changer. It can add a sense of mood into an image that black and white just can’t do. Just look at the terminology we use when talking about colour. Warm colours, cool colours. The colour in the image doesn’t have a temperature but our brains ascribe certain feelings to certain colours. Red equates to warmth, comfort, passion etc. Blue equates to cold, loneliness, distance.

Contrasting colours can also augment areas and help to lead the eye around an image. Have a look at these 2 images of the Bugatti car grill below. In the colour image the red logo is the most important feature that your eye is drawn to. In the black and white image our eye fights between the circular logo and the triangle one.

The red colour in the Bugatti grill is what your eye is drawn to

In the black and white version, the eye is drawn towards the teal logo shape

So how can we make our Black and White photos look awesome then?

We have a number of tools at our disposal. Using a combination of these can create a very powerful image. I have listed three of the most important ones below but there are a number of others you will discover yourself.

Shape

Our eyes are normally drawn to very clear shapes. Triangles have a particular power to attract our attention but any shape will still add to what makes a good black and white photo.

In the colour image of the Bugatti dashboard and steering wheel, you can see that your eye fights for attention between the steering wheel and the blue of the car body, but with the black and white image our eye just goes straight in to the most important shape that is the logo on the steering wheel.

On the Bugatti dashboard, your eye fights for attention between the blue body and the yellow wood

In this black and white version, the background blue doesn’t distract the eye from the dashboard and wheel and the logo shape is more obvious

Light verses dark

Where colour images use contrasting colours to differentiate areas in a photograph, in black and white photography we can use light and dark areas. Lighter areas with interesting contrast and shapes just scream out ‘look at me’. Darker areas and less detail tend to make the brain work too hard to see the detail so it automatically goes back to the lighter, easier to ‘read’ areas. A contrasting shape will grab the viewer’s attention as easily as a contrasting colour can.

The eye is drawn towards the lighter parts and doesn’t spend much time in the dark shadows

Texture

When we look at what makes a good black and white photo, one of the really important weapons we have in our armoury is texture. Texture is the one thing that can really give a black and white image punch. It gives the eye something to hold on to.

Texture is so much more apparent in black and white photos than in colour. Use it to your advantage.

You can see how the texture in the roof really jumps out in the image of the steam traction engine compared to the colour version.

The texture on the roof shows up beautifully on the black and white

The texture on the roof of the colour one is not as obvious

Whatever your reason to create an image in black and white over colour, be sure to make the image interesting. In colour photography we can control the viewer’s eyes and emotions with colour but in black and white photos we only have light to dark tones. Finding shapes in your image as well as textures and contrast will help you to lead the viewer’s eyes around your image. This will enable them to see the image as you envisaged it.

We photographed all the images in this post at the Aldham Steam Rally, UK.

Why would you wish to convert colour to black and white? After all, we all see in colour. There are so many reasons. Maybe the original image has too many clashing colours? It could be that the weird mix of colour balance (eg, a mix of outdoor light with some indoor lighting) in the image is just too time consuming to correct. Or perhaps you want to replicate old film. There are so many other reasons. But, I usually want to convert colour to black and white because it is just so very beautiful and striking.

This staircase that Ally photographed at our AirBnB in Bournemouth looks so much more graphical in black and white.

Here is the original colour version before converting to black and white

Surely you just choose a menu command and it’s done?

Well yes, you can do that but you would be missing out on the joy of controlling the converting of colour to black and white and seeing your image come alive. Most of the quick fix conversions just remove the colour from your image. This, more often than not, leaves a flat dull photograph that requires a lot of dodging and burning or contrast correction to give it more ‘pop’.

The technical explanation that you don’t really need unless you’re a geek or sitting in a coffee shop waiting for a friend!

All colours, whether in the real world or in an image have 3 main values.

1. The actual colour value (Hue)
2. The amount of saturation that colour has (Saturation)
3. And finally, how light or dark that colour is (Luminance / Lightness).

Colour Picker

This can be easily seen in a lot of colour pickers. It is usually referred to as HSL in software adjustments.

Hue, Saturation and Luminance (or Lightness)

So, to convert from colour to black and white, what we want to do is to remove the colour. But we also need to be able to adjust the lightness values of the separate colours individually. This is so we can maybe brighten up that beautiful red sunset cloud whilst at the same time darkening down the blue sky.

But this black and white voodoo never happened in traditional photography I hear you say

Ah, but it did. Here is some more geeky stuff to explain it. Traditional film (silver halide) is sensitive to light. So photographers used varying colour filters to lighten or darken parts of the image they were exposing. One of the most common filters was an orange filter. This absorbed blue light so when the image was exposed, less light from the blue areas got to the film, resulting in a darker blue. This was usually used on landscapes to make the sky go dark and dramatic whilst keeping the clouds white.

One of the greatest traditional landscape photographers, Ansel Adams, used yellow, orange and red filters on his camera to achieve the spectacular images of Yosemite and some of his skies are almost black in the print.

A different technique with film is to use a polarizing filter to darken down the sky.

We are doing the same thing, but with digital we can lighten or darken any colour in the image during conversion.

How the magic is done

In Photoshop or Affinity Photo go to your layers panel and at the bottom find the adjustment layers button. Add a black and white adjustment layer – in here you can lighten and darken the various colours to achieve a spectacular black and white image.

Using black and white to lighten and darken when you convert colour to black and white

Some tips to achieving black and white Zen

Quick tip 1: Try to pre-visualise your black and white image at the creating stage. Many mirrorless cameras let you change your display settings so the display presents in black and white. I use this technique a lot on my Sony A7R. This way, I concentrate more on the shapes and composition as well as the lightness values of the image. This helps stop me getting distracted by the colours. The great thing here is that the camera still records the full colour image, so I can have my cake and eat it!

Quick tip 2: If your camera doesn’t support this function you can take a coloured filter with you. View the scene through the filter to help get rid of distracting colours and enable you to concentrate on the lightness values and shape. Remember to take the filter off the camera before you take the photograph though. Also remember the filter might affect the way you see the values: such as a red filter will make the reds lighter and the blues darker. See our post on essential filters for black and white photography.

Quick tip 3: Geeky stuff alert! If you convert colour to black and white in the Raw file converter, be aware that the default file that opens in Adobe Photoshop will be a single 8-bit channel greyscale file. 8-bit channel images are made up of 256 levels of lightness per channel, from black to white. Therefore, a greyscale image only has 256 shades of grey. An 8-bit RGB image has 3 channels, each with 256 shades. This could mean you get banding in the beautiful graduated sky areas. (I will cover this in detail in a separate post soon.) More importantly, unless you convert the image back to RGB colour, you won’t be able to add colour in Photoshop, even in the form of text. You can do this by going to the Image menu > Modes > RGB colour.

In Summary …

Finally just remember… A boring photograph is still a boring photograph even if it’s converted to black and white. But a good photograph can sometimes become even more stunning once you convert it to black and white.
