When you want to develop a film or digital photo, you interact with the light in the future image. It becomes logical and necessary to want to modulate the light and\/or colour information in your images in order to express your artistic style. <\/p><\/div>\n\n\n\n<p data-block-type=\"core\">This is exactly what luminance masks allow you to do, in a powerful, simple and effective way. What's more, we're not stopping at just luminance masks, since we can also create colour, saturation or vibrance masks, as well as combining them. (especially in the latest version of Tony Kuyper's Photoshop plugin: the TK8)<\/p>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-7931c49\" id=\"2-le-principe-des-masques-de-luminance\" data-block-id=\"7931c49\"><style>.stk-7931c49 .stk-block-heading__bottom-line{background-color:var(--theme-palette-color-2, #a6003c  ) !important;}<\/style><h2 class=\"stk-block-heading__text\">2.

These selections allow you to adjust your image to the nearest pixel.<br>Creating a layer mask in Photoshop is generally done using the standard selection tools, such as the quick selection tool, the magic wand, the lassos, the feather etc... While these tools are very practical and useful when it comes to making selections based on contours and\/or contrast, they are not very effective if you want to generate selections based on the brightness or colour of your image.<\/p>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-a0bafcc\" data-block-id=\"a0bafcc\"><style>.stk-a0bafcc {margin-bottom:50px !important;}<\/style><p class=\"stk-block-text__text\"><br>Those of you who know Photoshop well will tell me, but why not use the colour range tool, which lets you create selections and\/or layer masks based on light, medium and dark tones, adjust the tolerance and range of tones, or use the selector of the following 5 colours: yellow, red, blue, cyan, green and magenta, which can be selected using this tool.<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-67bb474\" data-block-id=\"67bb474\"><style>.stk-67bb474 .stk--block-align-67bb474{align-items:center !important;}.stk-67bb474 {margin-bottom:50px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk--block-align-67bb474 stk-block-content stk-content-align stk-67bb474-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-5eade51\" data-v=\"4\" data-block-id=\"5eade51\"><style>.stk-5eade51 {align-self:center !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-5eade51-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-5eade51-inner-blocks\">\n<div class=\"wp-block-stackable-image stk-block-image stk-block stk-ef0f0ab stk-block-background\" data-block-id=\"ef0f0ab\"><style>.stk-ef0f0ab .stk-img-figcaption{text-align:center !important;font-size:12px !important;}.stk-ef0f0ab {background-color:var(--theme-palette-color-5, #e1e8ed) !important;box-shadow:0px 70px 90px -20px #4849794d !important;}.stk-ef0f0ab:before{background-color:var(--theme-palette-color-5, #e1e8ed) !important;}.stk-ef0f0ab .stk-img-wrapper img{transform:scale(0.81) !important;}@media screen and (max-width:999px){.stk-ef0f0ab .stk-img-figcaption{font-size:12px !important;}}<\/style><figure><span class=\"stk-img-wrapper stk-image--shape-stretch\"><img loading=\"lazy\" decoding=\"async\" class=\"stk-img wp-image-255970\" src=\"https:\/\/www.dragonstreetphotography.eu\/wp-content\/uploads\/2023\/01\/TK9-Multi-Mask.jpg\" width=\"480\" height=\"726\" alt=\"TK9 Multi Mask\" srcset=\"https:\/\/www.dragonstreetphotography.eu\/wp-content\/uploads\/2023\/01\/TK9-Multi-Mask.jpg 480w, https:\/\/www.dragonstreetphotography.eu\/wp-content\/uploads\/2023\/01\/TK9-Multi-Mask-8x12.jpg 8w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/><\/span><figcaption class=\"stk-img-figcaption\"><em>TK9 Multi Mask<\/em><\/figcaption><\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-dc576f2\" data-v=\"4\" data-block-id=\"dc576f2\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-dc576f2-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-dc576f2-inner-blocks\">\n<div class=\"wp-block-stackable-image stk-block-image stk-block stk-e97590b stk-block-background\" data-block-id=\"e97590b\"><style>.stk-e97590b .stk-img-figcaption{text-align:center !important;font-size:12px !important;}.stk-e97590b {background-color:var(--theme-palette-color-5, #e1e8ed) !important;box-shadow:0px 70px 90px -20px #4849794d !important;}.stk-e97590b:before{background-color:var(--theme-palette-color-5, #e1e8ed) !important;}.stk-e97590b .stk-img-wrapper img{transform:scale(0.84) !important;}@media screen and (max-width:999px){.stk-e97590b .stk-img-figcaption{font-size:12px !important;}}<\/style><figure><span class=\"stk-img-wrapper stk-image--shape-stretch\"><img loading=\"lazy\" decoding=\"async\" class=\"stk-img wp-image-255931\" src=\"https:\/\/www.dragonstreetphotography.eu\/wp-content\/uploads\/2023\/01\/TK-9-Combo-1.jpg\" width=\"478\" height=\"794\" alt=\"Photoshop TK9 Combo Panel\" srcset=\"https:\/\/www.dragonstreetphotography.eu\/wp-content\/uploads\/2023\/01\/TK-9-Combo-1.jpg 478w, https:\/\/www.dragonstreetphotography.eu\/wp-content\/uploads\/2023\/01\/TK-9-Combo-1-7x12.jpg 7w\" sizes=\"auto, (max-width: 478px) 100vw, 478px\" \/><\/span><figcaption class=\"stk-img-figcaption\"><em>Photoshop TK9 Combo Panel<\/em><\/figcaption><\/figure><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-9592bb1\" id=\"3-les-avantages-des-masques-de-luminance\" data-block-id=\"9592bb1\"><style>.stk-9592bb1 .stk-block-heading__bottom-line{background-color:var(--theme-palette-color-2, #a6003c  ) !important;}<\/style><h2 class=\"stk-block-heading__text\">3. The advantages of luminance masks<\/h2><div class=\"stk-block-heading__bottom-line\"><\/div><\/div>\n\n\n\n<p data-block-type=\"core\">The answer is quite simple: this tool, however good it may be, lacks flexibility and artistic naturalness. Photoshop's colour range tool can create masks or a selection, but only in 8 bits. This is a lack of precision when it is possible to obtain luminance masks in 16 bits. In fact, in 8 bits the gradations will be scaled over values from 0 to 255 but in 16bits it will be from 0 to 65535. In practice, this means that the contours of a selection will be much smoother and more progressive, and adjustments to an image will be much more flexible and the final result will be more natural in terms of both tones and colours.<\/p>\n\n\n\n<p data-block-type=\"core\"><br>Another advantage is that luminance masks based on colour can be adjusted according to the luminosity of the colour, in other words it is possible to create several luminance masks from a single colour (all in 16 bits).<\/p>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-5120c2c\" data-block-id=\"5120c2c\"><style>.stk-5120c2c {margin-bottom:50px !important;}<\/style><p class=\"stk-block-text__text\"><br>Even better, luminance masks can also be based on the saturation of an image.  This means that you can create several luminance masks depending on the degree of saturation or rather non-saturation of the colours in an image. This means that you can adjust the vibrancy of very slightly saturated colours with a 1st mask, the vibrancy of moderately saturated colours with another mask, and so on. Conversely, it is of course possible to desaturate certain colours that are too bright using a mask that you have created specifically for this purpose.<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-726027d\" id=\"4-conclusion\" data-block-id=\"726027d\"><style>.stk-726027d .stk-block-heading__bottom-line{background-color:var(--theme-palette-color-2, #a6003c  ) !important;}<\/style><h2 class=\"stk-block-heading__text\">4. Conclusion<\/h2><div class=\"stk-block-heading__bottom-line\"><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-c5311d0\" data-block-id=\"c5311d0\"><style>.stk-c5311d0 {margin-bottom:50px !important;}<\/style><p class=\"stk-block-text__text\">In conclusion, luminance masks are a way of creating masks&nbsp;<strong>Photoshop to adjust both tones and colours. But they can also be used to create effects, facilitate editing and easily filter all your complex image processing (sharpness, noise, clarity, etc.).&nbsp;<\/strong>&nbsp;Luminance masks give a very natural and powerful result thanks to their precision. They can be used on all types of photos, but although they are best known for landscape photography, they can also be very useful for portraits, for example, where gradients and colour adjustments are very tricky to manage.<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-e46e4b9\" id=\"5-comment-les-masques-de-luminance-peuvent-ameliorer-mes-photos\" data-block-id=\"e46e4b9\"><style>.stk-e46e4b9 .stk-block-heading__bottom-line{background-color:var(--theme-palette-color-2, #a6003c  ) !important;}<\/style><h2 class=\"stk-block-heading__text\">5.

Here are some general tips:<\/p>\n\n\n\n<ul class=\"wp-block-list\" data-block-type=\"core\">\n<li data-block-type=\"core\">Start by making simple show mergers.<\/li>\n\n\n\n<li data-block-type=\"core\">Use 2 exposures initially and more later (if necessary).<\/li>\n\n\n\n<li data-block-type=\"core\">Use exposures with a maximum of 1 stop difference. If you have more than this, balance the exposures in your RAW converter before going into Photoshop. (This will avoid washed-out effects that lack contrast).<\/li>\n\n\n\n<li data-block-type=\"core\">Don't expect to get a perfect result just by using luminance masks! Very often, you need to adjust the mask a little when you apply it, and the photo as a whole afterwards in terms of tonality, colour, contrast, clarity, and so on.<\/li>\n\n\n\n<li data-block-type=\"core\">Always organise your layers in Photoshop in the same way, dark exposure on top, light exposure underneath or vice versa, or use a neutral exposure to generate your luminance masks. The key here is to remain consistent in your workflow.<\/li>\n<\/ul>\n\n\n\n<p data-block-type=\"core\">To find out more about luminance masks and the <a href=\"https:\/\/www.dragonstreetphotography.net\/tutoriels-video-gratuits-photoshop\/\" target=\"_blank\" rel=\"noreferrer noopener\">TK8 Multi Mask video<\/a>.<\/p>\n\n\n\n<p data-block-type=\"core\">Have fun!<\/p>\n\n\n\n<p data-block-type=\"core\">David<\/p>","protected":false},"excerpt":{"rendered":"<p>L&rsquo;art des masques de luminance pour sculpter la lumi\u00e8re d&rsquo;une photo \u00e0 votre guise.
