How to Adjust Layer Opacity in Photoshop Elements 11
One of the easiest ways by far to make your images in Photoshop Elements 11 look interesting is to have one image ghosted over another. Creating this effect is an easy task with the Opacity option in the Layers panel. You adjust the opacity by selecting a layer in the Layers panel.
Then either access the slider by clicking the right arrow or enter a percentage value in the Opacity text box.
The Opacity setting allows you to mix the active layer with the layers below it in varying percentages from 100% (completely opaque) to 0% (completely transparent). Remember that you can adjust the opacity only on a layer, not on the Background.
You can also use the scrubby slider by pressing and dragging your mouse over the word Opacity in the Layers panel. Finally, you can also change the Opacity percentage by using keyboard shortcuts. With any tool active, except a painting tool or an editing tool, press a number key. Press 5 for 50% or 25 for 25%.
If you’re entering a 2-digit value, just be sure to type the numbers quickly, or else Elements interprets the numbers as two different values. You get the picture. Note that for the default of 100%, you must press 0.
