A proper white balance eliminates unwanted color casts, so that, for example, skin tones are rendered more naturally and white objects remain a true white in your photos.<\/h5>\n<p>[\/vc_column_text][vc_column_text]ProCamera has a built-in manual white balance feature, as well as an additional method for achieving white balance through what is called \u2018gray card\u2019 calibration. For this, the neutral tone of a gray card serves as the reference point for this calibration. It is important that the gray card is positioned in the same light as your actual subject. Once you have calibrated your white balance, which is performed by\u00a0a simple long tap on the AWB button, the metered value is locked for continuous shooting until you tap the WB button.<\/p>\n<p>Furthermore, a gray card can be used to adjust the white balance in post-processing software. By having the gray card visible in one of your shots, you will later be able to select a point or pixel on the gray card in your image editing software in order to set a custom white balance.[\/vc_column_text][vc_single_image image=&#8221;41010&#8243; img_size=&#8221;full&#8221; css_animation=&#8221;fadeIn&#8221; css=&#8221;.vc_custom_1446731375065{margin-top: 40px !important;margin-bottom: 40px !important;}&#8221;]<div class=\"ult-spacer spacer-69e79b092fc9a\" data-id=\"69e79b092fc9a\" data-height=\"25\" data-height-mobile=\"25\" data-height-tab=\"25\" data-height-tab-portrait=\"25\" data-height-mobile-landscape=\"25\" style=\"clear:both;display:block;\"><\/div><div class=\"hr-thin style-line\" style=\"width: 100%;border-top-width: 5px;\"><\/div><div class=\"ult-spacer spacer-69e79b092fcd4\" data-id=\"69e79b092fcd4\" data-height=\"25\" data-height-mobile=\"25\" data-height-tab=\"25\" data-height-tab-portrait=\"25\" data-height-mobile-landscape=\"25\" style=\"clear:both;display:block;\"><\/div>[vc_row_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1446731288994{margin-bottom: 40px !important;}&#8221;]<\/p>\n<h4>How to calibrate the camera with a gray card?<\/h4>\n<p>[\/vc_column_text][vc_column_text]<\/p>\n<ul>\n<li>Enable WB control in control panel (icon with the three lines, bottom\u00a0right).
