CMYK = cyaan magenta yellow and key (key for key color) [Actually Cyan magenta and yellow should all make black together if they are mixed. Pigments in paint/inkt just aren't strong enough so there is a extra key color witch is black]

RGB = Red Green Bleu
RGB = mixing light (add a red light bulb and a green light bulb and shine them together and you get yellow light(all of them together make wite light).

RGB and CMYK arent that complicated and to show that, someone invented color circles.

If you compare the 2 circles you see they are just the opposite of each other.

When the RGB light is mixed you get the CMY colors in the lapping point

When you do the same with CMY(mixing them) you get RGB colors.

The big difference is the way of mixing them as RGB works with light and CMYK with inkt
It is of course a bit more complicated as i explain here but in the big lines this is rgb and cmy(k)

I don’t know if i made this clear enough as my English is a bit blurry

And we know we’re humans. We can learn a monkey a tric. But before that we have to know how something works and how we’re able to reach a goal.

Keep going on

I have to say I have enjoyed every show so far and am looking forward to any future ones. I mostly enjoyed the walkthrough type shows but think the more technical episodes are just as valuable. I would be really interested in an in depth layer mode/ layer mask episode (or two!)

Just keep a good mix as you have been doing and I’ll be happy

I am thinking about a new structure for the next year. Perhaps different types of shows for different needs to fill.

The “Walkthrough” with an image from start to end (like shows – but that gets repetitive soon I fear. One short will come up at Christmas.

The “Concepts” like the layer modes explained in detail, wait for something like that at New Years Day. Well, it will be there at 19:00 UTC if my server got his clock right, but perhaps you have something better to do that day than waiting or it.

A “Toolbox” series – two of them are ready to go up in January. There I’ll try to explain a tool or plugin in depth.

Your posts got me thinking about a “Methods” type of show. A bit like the selective sharpening episode.

And then some stuff I haven’t really thought about up to now or that doesn’t fit into one of the categories. The next one will be a complete mix of everything. Then 5 shows that I have already recorded and partly produced and while they run I’ll have time to make some better plans. And have a break….

If you have any ideas – drop me a mail or a comment!

I would like to see some shows on post-processing with the Gimp; not a summary of technical possibilities, but rather the other way around: if one wishes a certain mood or effect, which possibilities are there to achieve that? This could be extended to compositing.

On the technical side, an explanation of the layer overlay modes would be most welcome.

Thanks and keep it up, Serge

I’ve checked most of the episodes and have found them of great use, specially because they’re geared towards my level of knowledge, i.e., not a pro, but not a newbie, either.

One thing I liked specially is that instead of simply explaining Gimp functions like in the manual, you have done so in the context of actually working on a photo, which makes it much more interesting and also truly helps one to learn, not just try to remember all the shortcuts and the functions.

Now this last episode was the antithesis of all this, so, in my humble opinion, I give it a thumbs down: over twenty minutes explaining how to pick a color? For people who understand the basics of colors and working with pictures, it is unnecessary, and for newbies, it is useless, until they know what they’re doing.

Don’t take me wrong, I love the show and urge you to stick at it, but I just wanted to give you my contribution in order for it to focus on what makes it special and really useful.

Of course, there’s no such thing as an “all-around” useful tutorial, because what one person finds daunting, the other finds too simplistic, and the balance is therefore impossible to achieve for everyone, so take this opinion of mine as a data point, and let’s see what the others think.

As for a suggestion of areas to explore in 2008, I think any post-processing work with different tools than the ones you explained already, would be a great fit.

Cheers,
