In this project, you can learn how to use Pixelmator to combine images into a textured collage using layers and blend modes. Collage is a technique primarily used in the visual arts,where a new piece of artwork is made from an assemblage of different forms.
You’ll first need to select three images to use for this project, a foreground image, a background image, and an accent piece such as these that I used. Note: The accent image should have a transparent background.
Open the image that will be used as the foreground layer. Duplicate this layer and name the copy Foreground.
Drag the other images into the Layers pallet as new texture layers on top. Name them Background and Accent.
Hide the original of the foreground layer and both texture layers by unchecking them in the Layers pallet.
Select the layer named Foreground and apply the Threshold filter from the Stylize group in the Effects Browser to that layer. Adjust the slider to get a clearly defined blackandwhiteonly image.
Unhide the Background layer and position it immediately above the Foreground layer (if it’s not already). Select the Move Tool and adjust the size and shape of the background image to fill the new image. From the dropdown list in the Layers pallet, set the Blending mode for the Background layer to Lnear Burn. Adjust the opacity for best effect. I used 70%.
You may want to reposition this layer a bit with the Move Tool to achieve a good relationship between the images.
Unhide the other texture layer. Accent. It should be on top. Set the Blending mode for this layer also to Linear Burn. Adjust the opacity as desired. In the example I used 50%.
Position this layer to get a good composition.
To complete the project, add a new layer to the top of the stack (Layer – New Layer) and fill it with color, Edit – Fill…. I used 945200.
Set the Blendingmode for this layer to Screen.I adjusted the opacity to about 66%.
And, here is the finished product. Please understand that I didn’t take the time to find perfect images that would lead to the creation of a nice piece of art. My purpose is to show you the fundamental steps that could be used to achieve an effect. Settings used in this example are only guidelines and you will need to adjust them to suit your images and desired result.
