I am not an expert photoshop user but have been trying to use more of it in what I currently do.

I have a black and white image from which I am trying to remove all the white.

I cannot use the magic wand/delete because the white is in literally hundreds of places and in some cases very tiny.

Is there a method to strip the white off, leaving just the black?

Thanks in advance for your help.

There's A LOT of ways to do this but the best method will depend on the image. Post a screenshot of what you're working with and then we can point you in the right direction. –  Ryan May 31 '14 at 12:28

Indeed you should perform right selection.

Select->Color Range and click on the spot colored with color you want to select - you will see the change on the preview screen.

Also, you can choose the color from sampled colors drop down menu

Fuzziness should be set to 0.

If you press SHIFT while selecting (you can also click Shift and drag of the image) it will select all the spots with the same color....

After selection was made you can perform on it any action you want...

If you just want transparency where the white is, you don't need Photoshop. This is a very simple thing to do in PowerPoint... 1. Paste the image into PowerPoint 2. Select the image 3. Hit the Format tab 4. Click Color 5. Click Set Transparent Color 6. Click on one of the white areas you want to remove. 7. Right click the image and Save as Picture.

Of course, this will only remove one color, so if there are shades of grey in your white, this is NOT a solution.

Sorry, but Powerpoint is not a tool to prepare good images, it is a tool to create style sheets. To create or change images one should only use programs prepared to do that, like gimp, photoshop, illustrator (vector graphics), Corel Draw etc. –  Kurt Jan 7 at 7:43

Actually, Kurt, PowerPoint 2010 has some very powerful image manipulation tools, and it is less intimidating than Photoshop. For many users, the changes you can make to images in PowerPoint may be good enough for what is needed. –  brookdancer Feb 24 at 22:16
