: Make image high contrast - 2 tone black and white Ive got a bunch of logos i want to display on a 'press' page, the logos all have different color schemes, which clash so i want to make

@Lengel450

maybe you could try converting the logo like you are converting a colour photograph to black and white?

Try Layers > Add adjustment layer > Channel Mixer and check on the "monochrome" option.

After that you just use the sliders to adjust the highlights and tones.

You can even add another adjustment layer > curves and change the tone of the image. I hope this helps and I used this method to convert colour images to black and white.

The Threshold Tool might be really helpful on this project. Then using Color overlay to pick a specific color. I realize that this thread happened about a year ago, but I thought I would post this just in case somebody else comes looking (like I did).

You can also use Blending Modes > Color Overlay on all the layers so you can make the logos any color you wish.

Use a Hue/Saturation adjustment layer and turn the saturation down to zero. You can then turn the lightness down as needed to make it black.

Edit: Sorry I assumed you had a transparent background. Instead, use the threshhold adjustment layer. It will turn your image pure black/white
