If you open the brush file from another layer’s adjustment layer, you can select any of the properties – opacity, blend mode, etc. – to be used to apply the paint operation to the image. For example, I have the effect “Paint Over Water” and will apply the paint operation to the water as it passes by. You can see how with the adjustment layer selected by the button, I can start the painting operation.
The other method that is useful is to set the brush size to the value specified by the image thumbnail image (like “32″). In my example above, if I set the brush to 32 in order to paint the water, you may see the water get pushed in some places, particularly near the end. To see how, click on the red button “Redraw.” From there, you can see which portions of the water are painted over by the brush:

Do you have any tricks for taking the most of your Photoshop’s color spaces?
The color filters in Photoshop work well on all types of images – white- and black-and-white films, vector graphics, and even printed images – and are a great alternative to the effects in other popular editing tools.
With that in mind, here’s a quick list of three Photoshop tools that are great for taking advantage of the color space of an image:
The Filter Effects panel: For many colors and hues, a quick change in the hue can be a huge help in making those elements stand out. Here, you can easily apply color transformations to selected areas of your image that enhance the desired effect.

The result can be very attractive on a picture or poster, and works great as an accent color in a photo shoot. The effect can also be applied to an existing image.
