Which rgb profile to use

The first thing to remember is that light is additive, while pigments are subtractive. When you view your images on a screen, that screen is producing colors in the form of light. RGB color mode combines the primary colors of light red, green, and blue in different combinations to produce the colors you need. It is best used for viewing on a screen. If you fill each pixel with the most saturated version of all three colors, you will get white. Sounds counterintuitive, right? Your computer screen is not a Crayola product, though.

Your computer screen emits light, and light and pigment behave very differently, which is why it is in situations involving light where RGB forgive a pun shines. You will probably get satisfactory results for run-of-the-mill prints with an RGB file.

Especially so if you opt in for the color management option that most pro printers offer, and pro labs often have recommended settings for optimal results listed on their websites. For magazines and other printed media, however, RGB may not always cut it. Such publications may have more specific submission requirements. In these cases, you can sometimes request a customized color profile that is specific to their printing process.

This is where CMY comes in. Cyan, magenta, yellow, and black inks are layered or mixed to create the desired color. The challenge here is that you are editing these soon-to-be printed images on a screen. Backlight, contrast settings, and other nit-picky calibration factors can affect your experience on a given device.

This one is pretty self-explanatory, but not everyone understands why it exists. Ideally, setting each color in your mode at the same number should produce a neutral color read: a gray. You might end up with a neutral-looking gray on your computer that translates into more of a warm gray on other devices or when you print. Colors are greedy, and any chance a color has to steal the show, it will take!

Grayscale gives those colors a reality check so you have gray and black. This simple RGB color wheel shows the relationship between primary red, green, blue and secondary cyan, magenta, yellow colors. For example, a fully saturated magenta tone contains no green RGB ,0, , so sits opposite green on the wheel. Tertiary colors are created by blending adjacent primary and secondary colors.

All RGB working spaces have the same number of colors; the gamut they cover is the main difference between them. Choice of RGB working space is, therefore, mainly about picking a gamut that suits your needs best. Standard RGB working spaces e. In other words, we know what to expect from them when we edit our photos. To illustrate this, if all three red, green and blue RGB values are equal in any pixel, the tone will always be neutral, be it gray, black or white.

Any adjustments made to shadows, mid-tones or highlights cause the same degree of change, too, so editing is always predictable.

Some subjects are better suited to this color space than others, like portraits. The types of subjects you shoot may play a part in choosing a working space.
