Two of the most confusing functions in Photoshop is probably the layer opacity and fill tool. What exactly does this two tools do? If you have been playing around with both these tools, you would have noticed that they do the exact same thing right? That maybe true, but obviously Adobe did not put two tools with the same function, that wouldn’t make sense.
In this article we will touch on the key differences between layer opacity and fill. At the end of the tutorial you will then understand how to better use opacity and the fill tool.
Step one: Open an image in Photoshop.
Step two: Use the text tool and type “Sweets” or any other words of your choice on the image. Adjust the font however you wish. You could adjust the size put an arc and etc…
Step three: Adjust the opacity slider to 50% and notice the effect. Observe the text when the percentage goes lower. By changing the percentage of the Fill slider, you can also achieve the same effect.
Step four: To see the difference between Fill to Opacity, you would first have to put some effect on the text layer such as outer glow and drop shadow on the layer style. You can find layer styles under the layer menu then layer styles.
Alternatively, you can click on the fx icon to bring up a list of layer styles.
Step four: Once you have set your desired layer style, play around with the fill and opacity sliders one at a time. You will notice that opacity affects the entire text and layer styles, fill only affects the filled portions of the text and leaves the layer styles alone.
So there you have it, the key difference between Layer Opacity and Fill.
