Channel help

Hi All, I have a photo that has been scribbled on by a two year old in biro (I think) If I go into channels it shows up in all the channels except blue, so I figure there must be a way to remove it. Any ideas?
Thanks Jo Jo

Re: Channel help

Jo Jo, I am afraid that you won't get by without cloning a little. I used following plugin to get rid of the scribbling: http://home.planet.nl/~ber03728/4N6site/main.htm

On a higher res image you might get much better results. Good luck

Re: Channel help

Use your blue channel make it gray then RGB.

Smudge the the places that need to me fixed,
then use the color brush to color the way you want. the picture to look.

Re: Channel help

Thanks Amica, but couldn't get the plug in to work.
Cupcake, I did what you suggested and this seems to be working, although when you say 'smudge' I presume you meant erase through to grey RGB? That's what I'm doing anyway.
Thanks both for your help,
Jo Jo

Re: Channel help

Jo Jo,
I see it in all channels. While pen is easy to eliminate in b&w images, it can be very hard in color images. It's just too hard to isolate. Color images with pen marks seem to always end up being lots of cloning, brushing in color blend mode, etc.

I often find one of the more useful, but most often overlooked tools is the clone stamp in color blend mode. This allows you to clone only the color of adjacent pixels into the damaged pixels. This preserves the luminosity of the original pixels, thus preventing a lot of noticeable cloning. However, it works best when there is not much difference between the luminosity of the two areas. So, how do you deal with that? Switch the clone stamp to luminosity blend mode for those other areas, where there is a big luminosity difference.

Try both on some test areas and you'll be surprised at the power they provide. Very useful in certain situations.
