Create another new blank layer and swipe up with the brush and watch it paint those jittery fellas. Now swipe in slightly the opposite direction. I chose blue as the foreground color
but say you don't like that and want to change the color of the flies, er Bflies
you must first select them by Ctrl clicking or select: load selection to change the color or gradient fill. If you don't you'll get one color or gradient across the entire layer and cover all of the width and height of the document hiding all layers beneath it. So make sure you load the selection first.
Now if you didn't like that pink butterfly layer you could wipe them from existence by choosing a blue gradient on linear foreground to background and swiping that straight up and down. This fills out all other pixel data. Or you could hide the pink guys and replace the yellow background layer (make sure it's selected in the layers palette) with the gradient swipe.
Here is another example of quickly using the butterfly brush. By changing the settings it makes it seem more natural because butterflies do fly in all different directions. Remember to create a new layer to paint them onto. Rather have video training? Click here.
You can also choose them from the options bar drop down menu as shown.
Choose the photograph that you think would look perfect with some vector shape/brush balance. Great design is using the power of tools (and understanding of them) to effectively get across your inner self or vision.
I've created a blank layer and filled with an outer circle of blue butterflies. You can do this too. Now create another blank layer.
