Remove logo problem

Hi guys,

I am trying to remove the logo (W) from this tennis racket and I find it quite hard. I've tried a couple of things like the colour replacement tool, the channel mixer but so far all unsuccessfully. What I want essentially is to remove the colour information and make it look like white like the rest of the strings.

Any suggestions (or threads that deal that kind of problem) would be much appreciated.

Thanks,

Nikos

Hi nikos, welcome.
I didn't try it but looking at your image I would approach it by creating two color selections and blending them to make one mask and then invert. The red looks like it might be difficult to select so I would select the black and white and blend them.

Re: Remove logo problem

Hi crazyfly1,

Thanks very much for your immediate response.

To be a bit more precise, I've managed to select the red string area and made an alpha out of it but that's all. My problem is the next step to get the red become white and blend seemingly with the rest of the string.

Because I'm not sure I understand what you're suggesting, could it be possible to expand on it a bit more?

Re: Remove logo problem

When trying to remove a specific color you can usually do it by mixing channels and using the channel of the color that is complimentary to the color you're trying to remove. You're trying to remove red and when using additive color the compliment of red is cyan so if you try to remove the color using channels you should use the cyan channel.

Here's some quick results I got using the cyan channel. I didn't take the time to perfect it so it's basically just a proof of concept but you could get a very convincing removal of the logo using this technique, and there are many other ways as well.

Re: Remove logo problem

thanks bgates87. I've had a little play and you are spot on. I think that's the way to do it.

It would be interesting though to hear from people other ways of approaching the problem.
