Sites like WePay.com or UnBounce.com have a horizontal band where they show their partners' logos. The logos have been converted to black and white and have a transparent background. How did they do this?
The black and white conversion I figured out; I simply pull up the saturation popup and move the slider all the way to the left.
But I can't figure out how to create the transparent background. If the source logo (screen-grabbed from the partners website) has a white background, for example, I know I can use the magic wand, select the whiteness, and click delete and a transparent background remains. This works -- but not cleanly. There are still rough edges around the letters in the logo. I can't figure out for the life of me what to do. I see countless other sites using this technique with no problem (see sites above). But I can't seem to figure it out.
FWIW: This is my first day using PhotoShop. I'm using the trial.
I attached a screenshot from unbounce.comthat shows the approach when it's done properly.
If you click File/new you can create a document with a solid or transparent background. Then just paste in your logo. Remember the above are trade mark proteted.
But if the third party logo has a background color baked into it, how do I paste it in on top of my transparent layer without their background color showing through?
I am assuming you are going to build your own logo and have a transparent background. If you have permission to use their logo I am sure you would get one without background.
