Make image high contrast - 2 tone black and white


Question

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 all the logos black and white, no greyscale, just 2 colours, black and white.

Ive tried in Photoshop to set the color pallet to greyscale and then up the contrast, but i still get allot of greys in the logos, any idea hows best to achieve this.

Id like to do something similar to this example were the logo is completely flattened, see there is no tonal effect on the letters as there is on the color version.

Just to be clear all the logos, are raster, rather than vector so they cant just be put into illustrator and changed.

Accepted Answer

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
