You can notice that the selected area is visible and everything else turns black. Once you click on the Refine Edge button, a new window pops out and the image appears to have been changed. The “Refine Edge” option of the quick selection tool (highlighted in red in the image below) comes to rescue in such a scenario. If I manage to soften the borders (edges) of the subject, I can make it look comparably more natural.

I am going to show you how to fix this issue by refining the edges.Īs I have mentioned earlier, the edge of the subject which is right next to the blurred background is what gives the image an unnatural look. That is because the selection is harsh ie., there is too much contrast between the background and the border of the subject that makes it look cut-out. You can see that the subject actually looks “copy-pasted”. Take a look at the illustrative image below to understand how the output would look if I just make a selection and blur the rest. Now that I have an isolated selection of the subject, I cannot just go ahead and blur the rest. It is the Owl and the branch on which it is resting, which obviously lies on the same focal plane. In the illustrative image, you can see the selection I have made. When you press Alt / Option, you can see the “+” symbol inside the mouse pointer turn to “-“. You can always click on the Alt (in PC) or Option (in Mac) to subtract an unwanted selection. Sometimes, if there are no definitive borders, Photoshop ends up selecting a part of the background. It seeks well-defined borders to make the selection. Photoshop makes the selection using the contrast between adjacent pixels. You can see the marching ants around the selected area and the selection adds up as you move it through. Click near the border inside the subject and drag the mouse around the area that you wish to select. When you hover around the image, you can see the mouse pointer with a “+” symbol in the center. You can use it by clicking the tool selection option from the toolbox (highlighted in red) in the illustrative picture below: This is one of the most common tools in Photoshop. We use the latter method when there is already a certain degree of subject isolation in the image. The other is to apply a gradient of selection from the focal plane. The first one is to select and isolate the subject alone, which comes handy most of the time. I will explain two options for selection in this article. As always with Photoshop, there are multiple ways to make a selection. Selecting an area of an image to be edited locally is one of the most challenging tasks in Photoshop. In other words, deciding how much is too much will be one of the most important factors that makes or breaks the image. So the first step is to decide how much blur is actually possible without making the image look “plastic” and the second step would be to decide which part of the image gets how much blur in post. I would be doing more so if I end up blurring the entire background equally. Whenever we decide to blur the background of an image, it is of primary importance that we understand the image.įor example, in the above image, if I attempt to completely blur out the leaves surrounding the subject, I would only end up with an artificial-looking image. In other words, there is no subject isolation.
The subject was pretty far away from me and the background was comparably closer to the subject, hence making everything sharp. So always make it a habit to duplicate the layer before proceeding and if the blur goes out of hand here and there, you can always adjust it using the opacity with respect to the original layer using layer masks.
Once done, it cannot be modified, making it a destructive form of applying a blur. Remember that the lens blur is directly applied to the selected layer.
