I know, you will say it does look like the one I posted yesterday, but as I promised here is the "Subtractive Color Theory" version.

Yesterday colors were RGB (Red Green and Blue). If you take a light ray of each of these colors and mix them together it will result in white light. The three colors add together and this is why we call it the "Additive Color Theory".

The colors we have tonight are complementory colors of the Additive Colors. Mix blue and red and we get magenta, blue and green and we get cyan, red and green... beleive it or not we get yellow.

So with three color light sources (R-G-B) we can get almost all the colors there is in the universe depending on the proportion of each colors. However if you only have a white light source, by placing filter of different density of the complementary color (C-M-Y) it will also be possible to recreate all colors in the universe.

Color slide film, or cinema movie film utilize the substractive theory. The projector has a white light source and the film is made of three layer of color dyes (filter) C-M-Y. This way we can see the movie or the slide show with a full array of colors.

You TV set or computer monitor work on the principle of Additive theory. It is made of tiny light dot and these are R-G-B. Because they are so small and the eye doesn't have enough acuity, they blend together in our mind and this way we recreate all the colors.

You will find included as a "workshop" a medium format image of the same subject. Resolution and graininess are better, but I prefed the 35mm composition.

Bonsoir Alain,
Excellente image pour accompagner la théorie des couleurs que tu expliques si bien dans ta note . Tu as eu une idée parfaitement originale avec l'utilisation des rouleaux de fils pour montrer les couleurs dont tu fais mention . Belle présentation et une note super instructive dans le genre que je voudrais voir plus souvent .
Daniel

very good compo nice shot. good pov

Bonjour Alain,excellente note: théorie de lumière 202! J'ai regaradé votre workshop et je suis d'accord avec vous pour la compo meilleure dans 35 mm mais le POV y est aussi pour beaucoup. Je suis un peu étonné de voir la profondeur de champs à 2.8. J'aurais pensé qu'avec une 6X6 le 2.8 apparaîtrait plus court comme zone de netteté. Je n'ai travaillé qu'une seule fois avec un 4X5 et la résolution est à couper le souffle.
C'est toujours agréable de voir une belle image faite à partir de quelque chose de banal. Félicitations!

Alain
J'aime bien la composition et les couleurs de celle-ci. Seul (tout petit) regret, les branches des ciseaux floues au premier plan (peut-être décaler un peu les ciseaux ou fermer un peu plus l'objectif pour une plus grande profondeur de champ?)
Amicalement

hi alain

the first one was good, but this one is definitely better, IMO. you sure can keep the momentum coming and not bored the audience with the sequel. :) with this one, i like the DOF better.

Hi Alain,

Superb DOF presentation, the placement of the objects in here
is vey well thought. Very good lighting, did you use flash?
I agree with regards to the additive color theory. Excellent composition!

Cheers,
Ramon

Bonjour Alain
Definitely different from the last one.Toned down quite a bit.
I like the compo again giving good results, and Ireally appreciate the fact that you want to help us understand the concept of colors and photography.

Bonjour Alain.

Encore ici, j'aime beaucoup la composition, incluant la MAP. La diffusion de la lumière est aussi très réussie. Bravo et merci pour ta note.

Amicalement

J'm beaucoup.

Hi Alain,

Yes! This is about the basics of sewing and stitching colored light strings on the tissue of phantasy for the purpose of having fun with it.
As I already mentioned, please go on explaining as much as you can afford time for...
Thank you :)
