Process 1 (Layer Mask and Field Blur)

Sample image, Blur Background Photoshop

First, open the image in Adobe Photoshop. Copy the layer by pressing Ctrl+J for Win or Command+J for MAC. Let’s rename this new layer ‘Subject’. Select any selection tool such as the ‘Quick Selection Tool’ and click on ‘Select and Mask’ on the upper portion of the window.

Selecting the subject - DSLR in Photoshop

A new window will open and click on ‘Select subject’. Photoshop automatically selects the subject with the use of artificial intelligence. If any portion is not automatically selected, you can use some tools to select those. For hard edges, you can use the ‘Quick selection tool’.

But, for soft edges, you can use the ‘Refine Edge tool’. Also, for this image, we will use black color as the background and opacity at 80%. With these settings, you can see the below image well and make the selection. Click ‘OK’ with the output to ‘New layer with layer mask’.

Let’s rename this ‘Subject’. Also, we have two other tutorials for separating the subject from the background. One is ‘The Easy Background Remover tool in Photoshop’ for complex subjects with a busy background. Another one is ‘ the Pen Tool in Photoshop’ for hard edges subjects for any background.

Content-Aware Fill (DSLR in Photoshop)

Now, press and hold Ctrl for Win or Command for MAC and left-click the mouse on the mask of the Subject layer. You will see a selection of the subjects. Go to Select>Modify>Expand and select the value ‘5’. Do not set the value to a much higher number. This will affect the natural look. Select the blur layer and go to Edit>Content-Aware fill.

Content-Aware Fill

Photoshop uses some calculations and fills the selected area with possible textures from nearby areas. You may see some impurities still left as below image. We will take care of them in a moment.

Select the ‘Clone Stamp Tool’, take a sample from the impurity-free area, and brush over the impurities. Do not brush over all the impurities by sampling once only. Each time sample from the nearby areas and brush over the impure areas. No need to be super accurate with the areas as they remain under the subject.

Copy the Blur layer and rename it ‘Mask’. Hide the Blur layer. With the Blur Copy layer selected, take the soft round brush and select the foreground color ‘Black’. Make the brush size a little bigger approximately 300 pixels. With the opacity, 100%, brush over the top portion of the image.

Then reduce the opacity to 50% and brush the right bottom of the 100% brushing area. Use 25% and 10% for the below portions and leave approximately 1/5 portion at the bottom of the image without brushing. We will know the reason for this procedure in the next part.

The final output is as below. The subject is intact, the blur has gradually increased from close to far. With this method, you can modify blurring from the ‘Mask’ layer. If you make the mask more transparent, it will be more blurry. On the other hand, if you create low transparency of any portion, the background will be less blurry.

Process 2 (Layer Mask and Tilt-Shift)

Sample image - DSLR in Photoshop

For the process, we will use a human model image with a wide background. As per the above process, we will copy the background layer for the subject and rename it ‘Subject’. For this subject, you may find it difficult to select because of hair. Nothing to worry about.

Use the ‘Refine Edge Brush Tool’ for the soft areas and brush over. Photoshop will do the math and select the relevant strings for your convenience. Check the box ‘Smart Radius’ and increase the radius to 8 px for the image. Use ‘Smooth’ 25 units to avoid harsh edges. Select output to ‘Layer Mask’ and press ok.

The mask will add to the subject layer. Make another copy of the background layer and rename it ‘Background’. By the way, it is not a must to rename the layers. We are doing it to explain specific information to make you understand more precisely.

You may find some impurities caused by the subject (See the right portion of the above image). Use the Clone Stamp Tool to cover up defects made by the Content-Aware Fill. If you can do that well the image would be as below. No need to perfect every pixel because it will remain behind the subject.

Tilt-Shift (DSLR in Photoshop)

Make visible the Subject layer but keep the Background layer selected. To add blur, go to Filter>Blur Gallary>Tilt Shift.

Tilt-Shift Blur - DSLR in Photoshop, Blur Background Photoshop

For this image, we are setting the blurring position as the below image and rotating a little. The reason for the rotation is, that you can see the left side of the image is closer than the right side. So, the blurring should be less for the left side and more for the right. If we do not do so, the effect may look unnatural.

The blurring process may take a little time and wait for that. Hit ‘OK’ when you are done. By the way, you can convert the layer into a smart object before applying the Tilt-Shift blur. This way you can modify the blurring settings anytime you want.

Adjusting Tilt-Shift Blur

The final output is as below.

Finishing Touch

Every editing that we do gets more attractive with a finishing touch. We have not added any kind of additional effect in the tutorial. You can use adjustment layers like Photo Filter, Channel Mixer, or Color Lookup for more dramatic effects. Also, you can use the Gaussian blur for a different effect.

Noise addition and the Boker Effect also give an image a little more extra touch. It is better to learn the effects of addiction and their utilization well before you apply them to images. Try to work non-destructive. You will have the freedom to work as you can go back anytime you need.
