Blend - the dictionary meaning of this transitive verb is "To combine or mix so that the constituent parts are indistinguishable from one another".
Yes this is exactly Photoshop provides us. Blending layer options provides us a way to combine the effects we make in different layers to finally produce the creative outcome we are looking forward to.
I would like to explain blending using a simple example to understand how it works. Usually while processing an image of a piece of art, we have to perform numerous trial and error before we can finalize on a blending mode we have to actually select for the layer where the final outcome is visually pleasing and creative.
Let’s quickly jump to the example.
Step 1 : Open an image. When we open an image, by default it will be set as the background, which can be viewed in the Layers palette.
Step 2 : Create a layer from the background. (Right click on the Background in the Layers palette and select Layer from background)
Step 3 : Duplicate the layer. (right click on the new layer created in step 2 in the layers palette and select duplicate layer)
Step 4 : Change the blending option to 'Soft Light' from the tiny dropdown list at the top left of the Layers palette. When a new layer is created the blending option that will be selected for the new layer will be Normal.
Step 5 : Adjust the transparency of the new layer to 50%.
Now we can see that the image looks a bit deep in colour and lighting where the shadows are further darkened and the highlights are lightened but the effect blends well with the original picture we had opened.
The above example is just a very simple way to explain what and how we can change the blending option of a layer. We can use more effects by creating different duplicates of the original layer, provide different blending options to each of the layers and then see how the final image looks.
Hope you enjoyed the post.
