Getting Accurate Colours

Do photographers still need to use a grey card or a colour checker?

Absolutely! A grey card is useful for most genres of photography when you want to get the correct exposure for mid-tones. It can also be quite handy when you are shooting multiple images and want to get a standard White Balance setting across images. A colour checker, on the other hand, is used when colour accuracy is of utmost importance such as while shooting certain products in the studio, or in mixed lighting situations. Repeated use of studio lights can result in colour shifts which can be also be tested using these checkers. Alternatively, you can use them to confirm the colour calibration of your camera, monitor and printer. You can also check the colour profiling of the camera.
