Can anybody PLEASE give me a usable explanation of the difference between these!!:thumbs:
 
One adds to....one takes away?

Yup, just confirmed with my daughter, they're still teaching it that way round in school :D

Just kidding mate :)
 
They're opposites.
What are you wimbling on about... or are you being a muppet
 
The simple version is:

Additive is like a computer screen - the more colour you add the brighter the result.

Subtractive is the opposite - the more colour you add the darker the result, eg. printed media, filters, etc.
 
Thats the puppy, its sort of coming back to me now.

Cheers pxl8, I remember now.
 
Add the three different primary colours of light you get white..... add their negatives (which is a subtraction) as pigments cyan, magenta and yellow yer gets yer Black.... simple...

With diagrams .... I is a smart Alec though cos I did know, honest! :clap:
 
Cheers to Chuckles and Pxl8!

You at least bothered to ask what I was on about!

we talking film processes here? Additive adds dyes to the emulsion i.e. Kodachrome; subtractive removes silver and leaves the dyes behind (which were already on the emulsion...(I think - it's been a while...), like Ektachrome (which was based on the old Agfachrome which the allies seized as part of war reparations at the end of WWII...)
