How can i do this on photoshop?

I want to erase all non-black colors in my image. how do i do that?


i only want to leave all pure black colors.How can i do this on photoshop?
It is easy to do that.


just go to ';Select'; menu and then click on ';Color Range';. In new window you must select your sampled colors. It's better to use ';Shadows'; mode as sampled colors for your work. After this click OK and right click on picture and click on select inverse. Then use delete key.





(for more accuracy, in Color range window you can click on any color of your picture that you want to select)How can i do this on photoshop?
Up the contrast a little so the black areas are black rather than dark grey...





Use the magic wand to select the black areas (hold down ctrl to add another area, there should be a little cross next to the wand if it will add). When they're all selected, go to Select-%26gt;Invert Selection. This should select everything that's not black. Then press ';delete'; or ';backspace';.





Hope this helps!
It depends on the image. But you can use Eraser, but that might take a while. You can also use Polygonal Lasso Tool as well. Using magic Wand Tool is good as well. You can click on the pure black colors and just Select Inverse to pick out the non-black colors then delete. Or use Magic Wand on the non-black colors then delete.





But these methods can't really be applied to all, so it all depends on the image. :|| Sorry if this is all so confusing. :(
