Blur Photo Border using Photoshop

Here is a quick and easy technique to blur photo border using Photoshop. I found this is helpful in portraits to bring more emphasis to the subject matter similar to adding a vignette. It is also helpful diminish any distracting details that may be in the background or  to blend an expanded canvas with the original photo.

1. In Photoshop, copy your Background Layer or click on the Background Layer to convert it to Layer 0.

2. You can use either the elliptical or rectangle tool to isolate the area you want in focus. Personally, I tend to use the elliptical tool more frequently. It seems to blend better for me.

3. Feather the area between 5 and 10 pixels. You may have to experiment with the amount depending on your subject and composition.

4. Invert your Selection by either using shortcut keys Shift/Command/I or the top toolbar Select > Inverse.

4. Create a Layer Mask by clicking on the Add Layer Mask icon on the bottom of the Layer’s Palette.

5. Create the blur using the Gaussian Blur filter. On the top tool bar select Filter > Blur > Gaussian Blur. You will also have to experiment with amount to get the your desired effect.

6. If the blur is too intense, use the Opacity Slider to decrease the amount on the Layer Pallete. If you would like to remove the blur from certain areas, use your brush tool on the Layer Mask  and paint in black the areas you want to remove or in black for areas you want to add the blur.

As with much of Photoshop, there are many ways to do one task or effect and to blur photo border is no exception, so experiment with this technique and other Blur options available under the Filter Toolbar or also with the Blur Tool.

Chromatic Aberration Removal

Sometimes Chromatic Aberration is noticeable on an image and a technique is needed for Chromatic Aberration Removal.  You may be asking what is Chromatic Aberration, so let me explain.  It is often found in images where there is an extreme contrast between the light and dark colors and/or highlight and shadows. The dynamic range and sensors on most cameras  just cannot record the two extremes, thus purple fringing occurs or sometime it comes in the form of green or red contamination on the darker color.

Here is a great technique I stumbled upon today to remove Chromatic Aberration using Photoshop CS5.

Here is one method for removing chromatic aberration:

1) Open the image in Photoshop CS5 and copy the Background Layer (CMD-J).

2)  Go to Filter > Blur > Gaussian Blur.  You can experiment with the amount of pixels here, but I had good luck using 15 pixels.

3)  Change the Blend Mode on the Layer to Color.

4)  Add a Mask to the Layer and then invert the Mask.  (CMD-I)

5) Paint with White to areas where you want to remove the CA. If you apply too much, change to Black and paint to remove.  Also, using the Opacity slider on the brush will help  control the intensity of the filter.

I also read  Lightroom 4 has a great tool to remove CA. I guess I will put that piece of software on my Wish List.

The more I learn about photography,  Photoshop and art the more I find I need and want to learn.

Happy Post Processing!

Just a quick update to this post. I have used this technique also with Photoshop CS6.
