F: Medium or highest opacity / high flow
+ the style
+ you can easily play with the transparency
+ you can easily change a colour using the fill tool
- the transparency..it's not really that clean.
I like this style, you can easily draw
G: Low opacity / high flow
+ the transparency
+ nice to sketch with
+ nice to work the anatomy of your characters before working with the line art
- any
For the example, I draw sketches in black and white, BUT you can paint your sketch with colours, it's interesting too:)
H: Low opacity / low flow
+ the mist effect
+ the sweetness!
- when the opacity is too low (5%) it's hard to see the effect.
- you can use it for the clouds, but this is really blurred, it's more interesting to add the opacity (30 - 50%) (set "D")
I: My favorite brush to add textures is the brush 63, available on Photoshop 7.
Changing the value of the flow or opacity, you add less or more details. For example the grass thing, the flow is low. For the stone, the flow is 30.
You can use the basic brush to add lights and shadows (for example the blue thing). Its gives more realism
J: The overlay mode is similar with the colour balance tool.
You choose a colour. You paint. Some pixels will be affected by the new colour the others are not.
For example: The cyan colour never changes, but the others are affected.
You can effect just an area too
K: Colour dodge is like the dodge tool (you can find it with the burn tool on the tool bar).
But instead of having a white effect, you are now able to add colour. You can easily change the mood with a yellow light for the morning or a orange light for the evening.
This effect is very clean
L: Thanks to the multiply mode, now you are able to print without erase the darkest colour.
It's like if you paint under the dark colour or if you used a second layer
This is interesting if you have a line art. You can colourise your character and try different colours without losing your line
