the lame program is photoshop.. sometimes my clients have logos that they want super imposed over the images on screen.. so what i then do is bring the logo into photoshop ,open a new project , set the resolution to 640 by 480 , magic wand out the background , and then fill it with the color im going to be keying out...so , when im choosing a color for the background , photoshop lets me decide which color to use by either clicking the color from the rgb palette , or by entering the six digit hexidecimal code for the color.. soooooo , thats why i asked... it also comes in handy when im doing some titling.. thanks guys.. any other thoughts? - eddie - www.dvforums.com |

Well, the hex code for colors is based on RGB, or is it the other way around? RGB for red is 255, 0, 0 the hex for red is #FF0000. Since not many things have such a pure green or blue, that is optimal. |

Take a closer look. Photoshop does allow you to use RGB color values as well. So like Tn said, just set your green or blue to 255 and that should be fine. |

Eddie, I was wondering, from an artistic point of view, do you find it better to fill the backround with green for keying out in post or just creating an alpha channel of the selection and comping that in post? |

I would always choose alpha channel if it's available. You get a perfect image of your superimposed element with no worrying about color issues, etc.If the artistic intent is to get a seamless composite, then I don't see why chromakeying would be perferrable. |
