Thanks Chris…I love your walkthroughs. They are probably amongst the best here at CGTalk and I really think they should be plugged.

One questions- when you are widening the range of colors, how much do you widen them by?

Also-- is there an equivalent to a ‘gel’ layer in PS? Would it be something along the lines of linear dodge? Or…?

Once again, thanks man. :thumbsup: :buttrock:

Thanks all - I’m glad you like the walk through.

Paperclip:
It does seem like a lot of good tutorials get lost in this forum, because the focus of the forum is so wide open (lots of small questions, etc.). That’s fine, but I’ll bet if there were a “finished works step by step” type of forum (where artists only post walk throughs, tutorials, or step by steps for really finished works), it would get a TON of visits. I think probably a majority of visitors is interested in learning how other artists work, and would check there every day (as many people do with the galleries). It seems you have to work really hard to locate good walk throughs on the different art forums, artists’ sites, etc. Oh well, I guess that’s what the user projects on CGTalk are for, but those take a lot longer to put together. It only takes a couple of hours to slap together a walk through like this.

To answer your question: there is no Photoshop composite method akin to Painter’s gel layer (at least not that I am aware of). If you load a .psd file with a gel layer (saved from Painter) in Photoshop, it defaults to a “Darken” composite method (which isn’t the same thing at all). I am still using Photoshop 5, because I do very little with it, but even with CS there is no layer like Painter’s gel layer. I bounce back and forth between the two programs, and this doesn’t cause any problems because the changing composite method does not alter the actual layer.

Of course, now that I’ve said that I just noticed that there is a list of links to tutorials in the “art techniques” forum in a sticky thread…

#8

Just another reason to spread the word about Painter, eh? I know you Painter types…:scream: You still didn’t answer my question about the color ranges! Sorry, but I like to leach knowledge from the masters, hope you don’t mind! :twisted:

#9

Good stuff. I added this to the sticky thread.

#10

Wonderful tutorial :] Very well executed and perfectly informative.
colour on top of a blank canvas, the texture background really adds something special.

#11

Beautiful breakdown. Thanks a lot for sharing!

Sorry paperclip, I forgot you asked that. BTW I don’t know what a “Painter type” is…

Anyway, as far as widening the range of colors, believe it or not that is a very complicated topic, and I’m not really sure how to quantify it. Also it varies a lot from picture to picture. Moreover, because of how the chemicals in our eyes work, the various color systems (HSV, RGB, Lab, etc.) don’t map the total color space in a way that parallels our perception. Put specifically, there is a lot more going on in the red, orange, yellow area of the spectrum than elsewhere. In this range, shifts of value and saturation create apparent shifts in hue. That means you can do pictures that according to measurable hue are very narrow, but seem to the eye to have a full range of color and hue. For example, keeping around the yellow area of the wheel (hue = 60), you can make an apparent “green” just by reducing saturation, and “blue” by reducing it more. This is why (whether they know it or not) a lot of artists work fairly monochromatically, using mostly “warm” colors, and low saturation. This is almost a guarantee of “color harmony”, and also makes it much easier to see value relationships, which is really the most important thing in a picture (compared to hue and saturation I mean). This is what’s happening in my Girl in the Iron Shoes, for example. If you open that in Photoshop and then open the color picker, and use the eye dropper to sample colors while watching the hue slider (hold the mouse button down and slide it around the picture), you’ll see that the hue range stays between approximately 30 and 60, but mostly hovers around 50 or so. But the picture lacks nothing for color. You don’t need the full spectrum to make a “color complete” picture. However, this does not work the same way on the other side of the wheel. If you adjust the hue for the entire Iron Shoes picture 180 degrees, it looks really monochromatic (blue). It looks like it only spans a small slice of the spectrum (which, in fact, is true). Basically our eyes are so much more capable of distinguishing subtle differences in the yellow-red (warm) area that we see other colors in there. We even have different names for them. Dull yellow is olive, light red is pink, dull dark orange is brown, etc. The cones in our eyes do NOT parallel the RGB phosphors in a monitor, and the way yellow is made in the eye is unique. Yellow only occurs when both red and green cones are stimulated, AND they are in approximately equal amounts AND the amounts are high. Originally mammals only had blue and yellow cones, so our ability to perceive hue was two dimensional. The yellow cone split (evolved) into red and green, but unlike, say, the phosphors in your monitor, the red and green cones are sensitive to the entire range of the spectrum (blue cones are essentially only sensitive to blue light). This is what accounts for the concept of so-called “warm” (vs. cool) colors. Warm colors simply have more light in them, that is, your eye is more sensitive to them and more chemicals are released when the eye perceives them, because for any colors other than blue, both the red and green cones are highly active. Very subtle differences between their levels produce the sensation of yellow, orange, red, yellow green, etc. Ok, enough about color perception.

For something like the Alice picture I wanted to represent more of the full spectrum directly. I wanted a mostly green picture, with a red (pink) Alice and a bluish caterpillar. So I gradually pull out the green sometimes by just making new colors and painting, and other times adjusting the whole picture, or separate parts, in Photoshop. Typically I use the “levels” control, selecting individual channels (R, G, B). But I also often switch the image to Lab mode, and then use the levels (in this case there are only A and B levels: red vs. green and blue vs. yellow). You can see the progression for this picture in the step by step images.

Hmm i cant see the pictures… if there are any(i hope.)

#14

That is an absolutely wonderful and informative walkthrough. And the painting itself is fantastic. Thank you so much.

#15

Great explanation Chris & very interesting to read!!

Thanks for explaining- much appreciated.

Still no plug…come on, someone! This deserves a front page!

#16

Thank you SO MUCH! Loved your tutorial/walkthrough! I am relatively unskilled at Painter yet and reading your walkthrough is so very helpful. Just seeing how you work a canvas gives me clues on how to handle the daunting task of turning a blank white screen into a finished piece. (The blank canvas is terrifying to me!) And I also love your explanation of warm and cool color perception. Went to your site and read all of those tutorials too. Great job! I know that creating a tutorial is a lot of painstaking work so a huge thanks for going to all the extra effort. It is much appreciated.

#17

First, thank you very much for this tutorial. I enjoy your work.

Second, and this may be a stupid question, but i’ll risk it and ask anyway. What exactly do you mean by using the buildup method? I tried using a search, but i couldn’t find anything (on this forum). Would you possibly be able to explain?

#18

ScottJohnson,
Hey, there’s no such thing as a stupid question! Painter (like all programs) uses these terms that are only somewhat meaningful… and sometimes misleading. The brush “method”, according to Painter help, describes the “most basic behavior… blah blah.” For example, “eraser” is one type of method. This type removes “paint” when you draw with it. The most common ones I think are “cover” and “buildup.”

This is from Painter’s help file on the two methods:

"The Buildup methods produce brush strokes that build toward black as you overlay them. A real-world example of buildup is the felt pen: scribble on the page with blue, then scribble on top of that with green, and then red. The scribbled area keeps getting darker, approaching black. Even if you were to apply a bright color like yellow, you couldn’t lighten the scribble — it would stay dark. Crayons and Felt Pens are buildup brushes.

The Cover methods produce brush strokes that cover underlying strokes, as oil paint does in a traditional art studio. No matter what colors you use, you can always apply a layer of paint that completely hides what’s underneath. Even with a black background, a thick layer of yellow remains pure yellow."

Like all things with Painter (for me anyway) the attempt at mimicking the behaviors of real world media is secondary to simply figuring out how to make the controls give you what you want.

Chris, thanks for the explination. it definitely helped me understand your approach better.

#20

That is a GREAT walkthrough. Your workflow is facinating and it really makes me want to experiment more with Painter.

#21

Nice !
