Floodfill Tool Effect
using Masks


Created by: CarolynR.
This tutorial will teach you how to blend two images by adding masks and using the Flood Fill tool. In this exercise we have used two images - "/tutorial/html/tut7eff/angels.jpg" and "/tutorial/html/tut7eff/clouds.jpg". Firstly you will cut out all of the white bits on the angel image, next you'll copy the angel into a new layer on the clouds image, then finally use masks and gradients to blend your images. The PSP tools you will use include the Zoom, Flood Fill and Magic Wand tools.

Finally, the steps below show how to perform each task using the PSP menu options. Alternatively, you may wish to use the keyboard shortcuts for some of the tasks - these are displayed in small text - surrounded by [square brackets].

Save your image
Last but not least, while still in the mask editing mode, you'll flood fill the clouds mask with the rectangular gradient.

Tip Tip:
Another way to give better contrast for a faded image is to merge all layers, duplicate the merged layer, and - on the duplicated layer - change the Layer Blend Mode to Overlay, then reduce the transparency of the duplicate layer to around 40%.

This is the end of the tutorial.
