Yes, Yonathan, you've got the basics of it. Although I fill 100% of the screen, not wanting to leave anything to chance.

The use of such cards, with maybe the exception of the minus green, is to enhance (warm) the image's overall tone. Many people don't like the "cool" image that is had with digital video. Hence, they look for ways to "warm" it up a little.

The problem is, of course, when you warm the flesh tone using the cards, you warm everything. And in some situations, you may not want everything "warm."

In a "dramatic/narrative" video, you might have shot some exteriors, or interiors for that matter with natural light) in the late afternoon or very early evening when the sun's color temperature was "warm." You could, with testing, shoot the following shots the next day, earlier in the day using the warm cards to approximate the "warmth" (color temperature) of the material you had shoot the evening before--just one example.

The uses of such cards are limited by your taste and your imgination.

Thanks.

For the video I'm making I can barely picture one scene where I wouldn't want vibrant, saturated and vivid colours...

It's mostly set in the Caribbean, on beaches, dirt roads, etc... lots of sunrises, sunsets aswell as mid day shots in the heat of the day. So I guess that warm cards and filters are the way to go? :)

The code works like a charm for the warm 1 and 2. The warm 1/2 is coming out almost purple. I haven't tested it on my monitor yet.

To convert to RGB from CMYK go to colorsnob

It'll give you the hex codes for RGB

Edit
I changed the value for magenta to 2 for the 1/2 and I got a better result. The CMYK formula wouldn't convert on the CMYK to RGB conversion program.

Charles,

A-4 is the standard printer paper size. In inches it's approx 8 1/4 x 11 1/2. In the US it's commonly called "letter" size.

hehe cheers for cleaning that up :) I can never remember the measurements! :)

Letter is a bit smaller than A4 though. Not much....

"US Letter" is short and fat and "A4" is tall and skinny. Kind of the Laurel and Hardy of paper size comparisons.

*But like Rob says...the difference isn't that big.
