I'm trying to remove the white background of an image (replacing it with transparency), however, the challenge I'm having is that the image has white parts that I would like to maintain. Below is the image I'm working with. Bare in mind that this image is work I've done and all rights are reserved under copyright law.
The center part of this wave is white, which adds a glowing effect. What I want to do is remove the white background around the outside of the wave, while still keeping the white colors in the center of the wave.
I'm using Photoshop for editing. What could I do in Ps to achieve my desired results? How could I select the white colors on the outside of the wave, without selecting the center white colors? If I could get a good selection, then I can just simply delete the colors, but maybe selections aren't the only way to solve this problem?
Please give me some useful explanation, or perhaps a tutorial even, video tutorial, giving instructions on how to remove the background for this particular image.
Thanks for reading. All help is highly appreciated.
