I've looked at a couple of previous questions, but I haven't been able to apply it to my question.

I'm trying to extract the black from this picture (so I can turn it into a vector later in Illustrator):

One answer to this previous question suggested fiddling with the input levels, but mine don't look as nice as the ones they show and I can't find a setting where white is totally white and black is totally black.

When I add an adjustment layer converting it to black and white and I try to place it into Illustrator, I get this:

I've also tried following this answer's suggestion and do filter | stylize | find edges and I'm getting close, but I don't have optimal results yet:

For your image I would use Channels.

Go into your channels and notice the red one has the best contrast. Duplicate that channel and then use the Curves to adjust it. At the bottom of the Curves panel you can eyedrop the black point to your text and the white point to the background. Maybe tweak it a little. You get pretty close already. Might have to do the "Just Right" part on its own since its a bit lighter but in no time you should be real close.

Then just use that as a Mask on your original:

I'd clean up the little bit that's still rough on the edge which should take two seconds and like I said probably do the "Just Right" again with the same technique but making sure its pure black if that's what you want.

  • Thanks Ryan, what would be the best way to clean it up? Using a brush? – nachocab Sep 22 '15 at 5:30
  • @nachocab brush, masks, eraser, marquee, levels adjustment, whatever you want and know how to use to achieve the desired results. – Ryan Sep 22 '15 at 10:16

enter image description here what I did is : used black&white fill and then use level(Ctrl+L)and make it full white background, see screenshot-1

enter image description here

Then I merge all three layer which you can see on layer panel in first screenshot using (Ctrl+E), and used magic wand tool to select the white background and ka-boom.. press DEL button.. :) Got transparent image
