ShiPainter/ShiPainter Pro hidden tools:
#1 The eyedropper.

Everyone knows this.

How?
Right click on color you want in a picture to get it. Also, right click on a blank place on the palette and the color you have will be copy/pasted in that spot.

#2 Secret brushes.

Everyone likes the word 'secret', right?

How?
Right click on the brush size on the palette, and window will come up, saying Normal, Watercolors, Airbrush, or Epen. I usually like water2 on ShiPainter Pro, with waters, airbrush, or epen selected. I'd call this water2:airbrush or water2:waters.

The epen setting produces 'brush-like' results, especially when all the way down on the brush size. The numbers should show a pattern for brush size on epen: 30, 60 something, 30, 60, 30, 60. Each new '30' is a new brush; 30 is small size, and 60 is large size of that brush. I like to use the bottommost 30 and 60 pattern; the brush has spiked edges and is great for textures like laying in grass. Test all these combinations, you might find something you like more than the default.

#3 Mask.

Replace a color with another. ie: turn black into blue, red into white

How?
Open the color window. There's two boxes, one left big one, and a small right one. Click the right one to put in a color that you would like to replace, and then go find and select the color you'll replace it with: Right now, the color you want replaced is on the right, and the color you're replacing it with is on the left. Right click on the right one, and a window comes up, saying reverse, mask, and other stuff. Select reverse, and wipe a pencil/eraser all over the canvas. Play around with this, it's very useful.

How to use mask to make flawless coloring and save your hand:

Note: This only works if you have solid line art.
After you finish your messy coloring, go onto your line art layer and fill outside the line art with a color unrelated to your subject; say, green! Now merge your line art and coloring layers together. Now you should have a colored character with a green background. Open up your color choosing window. Make sure your green color is selected, and click the small right box.

Now, switch to white and have your eraser ready. Right click the small, right, green box and select reverse. Erase all the green and voila! You now have all your coloring inside your line art without having to zoom in and get the color in the lines!

#4 Layer secrets.

You think you know, but you don't. :b Roll in your ignorance. *shot*

How?
Double click/right click a layer, and press the dropdown box where it says 'Normal'. The features are Multiply and Reverse. The highlight here is multiply, an especially useful feature for making smooth line art [below]. The layer 'multiplies' with a lower layer, so that darker wins out over lighter [like real paint], so that white probably wouldn't show up over any other color. Reverse is merely inverting colors.

How to use multiply for smooth, pen line art:
If you'll notice, it's very annoying to any type of eraser on pen line art, as it's either too smooth or too solid. Why not use a white pen as an eraser? When you're finished, set the layer to 'multiply', and when you color underneath, no white pen! Ta-dah!

Skills & Drawing

#5 Motion.

*Crash*

Why?
Sometimes blur adds to a very active piece, placed sometimes at the edges of forms, and is especially nice for running and motion or such. Keep in mind not to blur too much, as sometimes it's better to leave in features and details that may otherwise be lost in a smudge wasteland. The Shi gradiant tool is very poor for showing motion; use water2 set clear and very low: A 10 about, and drag out at the edges.

Some pieces actually look great without any blur at all, and it's merely that 'frozen in time' aspect that keeps it real: dirt flying, subjects in midair. Note the poses that people and animals usually assume when running or jumping.

#6 Lights, camera, action!

Sometimes, we get a great action piece idea, but executing it is harder than catching the idea itself. Remember these three elements-

LIGHTS! Determine the best lighting, the most dramatic possible, with cast shadows on features and such. Or something I had suggested earlier, cool dark atmosphere, with sharp warm highlights. You decide!
CAMERA! Composition is one of the most powerful tools in drawing. Consider whether a view up close, far, right in the action, or others that may make the most interesting. Play with perspective studies before executing an idea. Determine whether or not it is eye-catching or dull.
ACTION! Make the action interesting, and sometimes anime exaggerations really are all that some pieces need to look amazing.
