1. Shoot RAW + JPEG
The best monochrome conversions are made by editing raw files which have the full color information, but if you shoot raw and JPEG files simultaneously and set the camera to its monochrome Picture Style/Picture Control/Film Simulation mode you get an indication of how the image will look in black and white.Many cameras are also capable of producing decent in-camera monochrome images these days and it’s worth experimenting with image parameters (usually contrast, sharpness, filter effects and toning) to find a look that you like.
Because compact system cameras and compact cameras show the scene seen by the sensor with camera settings applied, users of these cameras are able to preview the monochrome image in the electronic viewfinder or on rear screen before taking the shot.
DSLR users can also do this if they activate their camera’s live view system, but the usually slower responses mean that many will find it preferable or check the image on the screen post-capture.
2. Look for Contrast, Shape and Texture
The complimentary and opposing colors that bring a color image to life are all reduced to black and white or shades of grey in a monochrome image and you have to look for tonal contrast to make a shot stand out.Fortunately, it’s possible to work adjust the brightness of these two colors separately to introduce some contrast. However, a good starting point is to look for scenes with tonal contrast.
There are always exceptions, but as a general rule look for scenes that contain some strong blacks and whites.
This can be achieved by the light or by the brightness (or tone) of the objects in the scene as well as the exposure settings that you use. The brightness of the bark of a silver birch tree for example, could inject some contrast (and interest) in to a woodland scene.
Setting the exposure for these brighter areas also makes the shadows darker, so the highlights stand out even more. Look for shapes, patterns and textures in a scene and move around to find the best composition.
3. Try Long Exposure
Long exposure shots can work really well in monochrome photography, especially where there’s moving water or clouds.The blurring of the movement also adds textural contrast with any solid objects in the frame. If necessary, use a neutral density filter such as Lee Filters’ Big Stopper or Little Stopper to reduce exposure and extend shutter speed (by 10 and 4 stops respectively).
Naturally, when exposures extend beyond about 1/60 sec a tripod is required to keep the camera still and avoid blurring. It’s also advisable to use a remote release and mirror lock-up to minimize vibration and produce super-sharp images.
4. Use Filters
Graduated neutral density (AKA ND grad) and polarizing filters are just as useful in monochrome photography as they are in color. In fact, because they manipulate image contrast they are arguably more useful.Don’t be afraid to use a ND grad with a standard neural density filter if the sky is brighter than the foreground in a long exposure shot.
Colored filters, which are an essential tool for monochrome film photographers, can also be useful for manipulating contrast in digital images.
They work by darkening objects of their opposite color while lightening objects of their own. An orange filter, for example, will darken the blue of the sky while a green one will lighten foliage.
5. Take Control
Although coloured filters can still be used to manipulate contrast when shooting digital black and white images, it’s more common to save this work until the processing stage.It’s possible to adjust one of these colours to make it anything from white to black with the sliding control.
However, it’s important to keep an eye on the whole image when adjusting a particular colour as subtle gradations can become unnatural looking.
And adjusting the brightness of a red or pink shirt with the red sliding control, for instance, will have an impact on the model’s skin, especially the lips.
The Levels and Curves controls can also be used to manipulate tonal range and contrast, but the HSL/Grayscale controls allow you to create separation between objects of the same brightness but with different colors.
6. Dodge and Burn
Dodging and burning is a technique that comes from the traditional darkroom and is usually used to burn in or darken highlights and hold back (brighten) shadows.This means that you can use the Burn tool to darken highlights when they are too bright, or the Dodge tool to brighten them to increase local contrast.
It’s a great way of giving a sense of greater sharpness and enhancing texture.
Plus, because you can set the opacity of the tools, you can build up their effect gradually so the impact is subtle and there are no hard edges.
