Layer Opacity and Fill controls the transparency of a layer in Photoshop. Since they both do the same thing, what is the essence of having the two of them on the Layer Panel? The main difference has to do with the Layer Style. While Opacity affects both the selected object and the layer style applied to it, Fill affects only the object leaving the layer style unaffected.
To buttress our point, let’s use the following example:
Example 1: Opacity and Fill without the Layer Style
We have a red background and with a word (Daddy) written on the background below:
Now, reduce the opacity to 27%, and below is what you will get
Return it back to 100% and reduce the Fill also to 27 percent, you will discover that you are still getting the same result below:
Example 1: Opacity and Fill with the Layer Style
As you can see above that we have applied a Stroke Layer Style to the text (daddy).
Now, let’s reduce the opacity to 27 and the transparency will be on the text and it’s layer style (the stroke) as seen below:
But if you reduce the Fill to 27%, it will only affect the text and not the layer style (the stroke) as also seen below:
So the only difference between the Layer Opacity and Fill is in the application of Layer Style….chikena!
