Something fix we won&#8217;t move: this element let us build a stable light balance. This element is the camera.<\/p>\n<p><strong>V-RAY PHYSICAL CAMERA<\/strong><br \/>\nSettings:<\/p>\n<ul>\n<li>f aperture = 8 \/ default<\/li>\n<li><strong>Shutter speed = 50<\/strong> \u00c2\u00a0(it is a fraction of second, actually it means 1\/50)<\/li>\n<li>ISO = 100 \/ default<\/li>\n<li>White Balance = neutral<\/li>\n<\/ul>\n<p>[private Premium|Premium-1year|bluevilla|5trainings]<\/p>\n<p>The camera is our &#8220;column&#8221; to start: the correct approach is ALWAYS thinking the light hierarchy: we need to focus who are the <strong>Primary<\/strong>, <strong>Secondary<\/strong> and <strong>Fill<\/strong> lights.<\/p>\n<p>The correct workflow is working 1 light category per time. Work on the only primary lights, when they are ok turn off primary lights and work only on the secondary lights and so on.<\/p>\n<p>&nbsp;<\/p>\n<p>In this video I&#8217;ll show you how apply these concepts:<\/p>\n<p><iframe loading=\"lazy\" src=\"http:\/\/player.vimeo.com\/video\/43888826?byline=0&amp;color=ff9933\" frameborder=\"0\" width=\"950\" height=\"534\"><\/iframe><\/p>\n<p><em>I really feel sorry for my english! \ud83d\ude41<\/em><br \/>\n<em>I just do this because I know that a lot of you prefer narrated versions.<\/em><br \/>\n<strong><\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>NOTE: About Color Mapping and Curves<\/strong>.<\/p>\n<p>In this video I used &#8220;<strong>Exponential<\/strong>&#8221; as color mapping and I modified curves in the v-Ray frame Buffer.<\/p>\n<p>I did this way because I know that strong lights in the interior and soft light in the exteriors will be difficult to manage in a linear space. Especially working in interiors with artificial lights the overexposure is unavoidable so exponential is the best solution. Finally curves help me to better control the quantity of lights between brighten and darken areas.<\/p>\n<p>For more details about these concepts, please check:<\/p>\n<ul>\n<li>Lesson 6:\u00c2\u00a0<a href=\"https:\/\/www.cg-blog.com\/index.php\/v-ray-for-beginners\/lesson-6\" target=\"_blank\">V-Ray Frame Buffer (as know as VFB)<\/a><\/li>\n<li>Lesson 7:\u00c2\u00a0<a href=\"https:\/\/www.cg-blog.com\/index.php\/v-ray-for-beginners\/lesson-7\" target=\"_blank\" data-bitly-type=\"bitly_hover_card\">How V-Ray IES works<\/a><\/li>\n<li>Lesson 10:\u00c2\u00a0<a href=\"https:\/\/www.cg-blog.com\/index.php\/v-ray-for-beginners\/lesson-10\" target=\"_blank\" data-bitly-type=\"bitly_hover_card\">Understand Color Mapping<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: center;\">FIX ARTFACTS<\/h2>\n<p><strong>Fix light cache leaks<\/strong> and imperfections:<\/p>\n<p><a href=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2012\/06\/retrace.jpg\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2012\/06\/retrace-icon2.jpg\" alt=\"\" width=\"600\" height=\"309\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Fix overlapped faces:<\/strong><br \/>\nThis issue is usually caused by imported 3d models.
