Camera Basics White Balance White balance is a feature that ensures that the colour white is reproduced accurately regardless of the type of lighting under which a photo is taken At a very basic level, it is common to use the Auto White Balance setting However, this setting is no one -size-fits-all solution For a white balance setting that best suits the lighting source, choose one of the preset white balance settings on your camera White balance makes sure your pictures turn out with the appropriate colour tone for the lighting Points-to-note - Its original function is to ensure that white appears white in your photos - You can also use it to add a colour cast to your photos Depending on the light source, the photo you take of a white object may take on a colour cast, appearing reddish or bluish, for instance This is something that is not apparent to the naked eye, because our brain automatically corrects the colour casting so that the white object still appears white regardless of the light source However, cameras don’t have that ability Instead, this function is carried out by the white balance (WB) function, which ensures that white objects are depicted as white in photos regardless of the light source Most of the time, if you were to shoot with white balance set to the "Auto" mode, which is also commonly known as Auto W hite Balance (AWB), the colours in the photo would be quite close to those that you see with your naked eye However, for some scenes, "Auto" is not able to make the appropriate corrections, which results in colours being depicted differently from those that you see When this happens, choose a white balance setting from among the presets You will have a few options, such as “Daylight”, “Shade”, “Cloudy”, “Tungsten light”, “White fluorescent light” and so on However, you can also use the WB function to i ntentionally add a colour cast to your photos Try it out for yourself: First, take a photo with the “Daylight” preset Compare it with photos taken with “White fluorescent light” or “Tungsten light” See that the images are more bluish in tone than the on e shot with “Daylight”? Next, try “Cloudy” and “Shade” You will get images that are warmer in tone Take note of these effects—you can use them to create drastic changes to the look of your final image The difference between the various white balance presets Auto Daylight Shade Cloudy Tungsten light White fluorescent light All examples shot with: EOS 5D Mark III/ EF50mm f/1.4 USM/ FL: 50mm/ Aperture-priority AE (f/1.4, 1/6400 sec, EV+1)/ ISO 100 These were shot outdoors on a fine day Compared with the photo shot with the “Daylight” preset, the white house looks warmer in the “Shade” and “Cloudy” examples, and cooler in the “Tungsten light” and “White fluorescent light” examples Under normal circumstances, we recommend using “Auto” when shooting outdoors because it gives a more natural look Auto Daylight All examples shot with: EOS 5D Mark II/ EF70 -200mm f/4L IS USM/ FL: 70mm/ Aperture-priority AE (f/4, 1/250 sec, EV -1)/ ISO 100 The sky during sunrise and sunset are reddish in to ne When you photograph them with white balance set to “Auto”, the function tries to correct the red-cast clouds so that they will appear white, and this mutes the reddish colours in the sky If you want to emphasize the reddish tones instead, here are the presets to try in order of increasing effect level: Auto→Daylight→Cloudy→Shade Auto Cloudy All examples shot with: EOS 80D/ EF -S18-135mm f/3.5-5.6 IS USM/ FL: 135mm (216mm equivalent)/ Aperture -priority AE (f/5.6, 1/200 sec, EV+1.7)/ ISO 200 If you were to photograph the light of a tungsten bulb using AWB, the light will appear white in your image, although it really is a warmer tone For a more accurate depiction of the white, choose the “Tungsten light” preset For an even warmer tone, choose either “Shade” or “Cloudy” These settings will impart an overall reddish tone, giving the entire photograph a warm feel White balance correction function If we were to get technical about colour tones, white balance presets can only adjust colour tones alo ng the amber/blue axis To adjust along the magenta/green axis, use white balance correction function This emphasizes the purple/green tones, which can make subjects look more appealing To set the white balance correction function, first, fix the colour tone of the entire image by choosing one of the white balance presets Then, in the white balance correction menu, adjust along the magenta/green axis If you need to, also adjust for blue/amber, and there you have it —your customtoned image From the SHOOT menu, select [WB Shift/Bkt.] to display a screen like the one above Shift the square marker to the desired position on the grid The letters on the [WB Shift/Bkt.] grid each represent a colour Move the square marker in the direction of the colour you want to emphasize Examples of white balance correction Normal A:9 B:9 G:9 M:9 All examples shot with: EOS 6D/ EF24 -105mm f/3.5-5.6 IS STM/ FL: 24mm/ Aperture-priority AE (f/3.5, 1/500 sec, EV+1)/ ISO 100 In the above examples, I shifted the square marker by the number of units indicated in the caption for A(mber), B(lue), G(reen) and M(agenta) respectively The effects of the adjustments are clear in the final images that result ... by the white balance (WB) function, which ensures that white objects are depicted as white in photos regardless of the light source Most of the time, if you were to shoot with white balance set... reddish tone, giving the entire photograph a warm feel White balance correction function If we were to get technical about colour tones, white balance presets can only adjust colour tones alo ng the... magenta/green axis, use white balance correction function This emphasizes the purple/green tones, which can make subjects look more appealing To set the white balance correction function, first,
