This is how to get a coloured image to a black and white image. To do this you copy the image over in to Photoshop. Then you can do it in two ways. One is to manly do with the histogram and to get to this you go to image - adjustments – desaturate. This brings the image to the colours black, white and grey. Then you go to image – adjustments – levels and the histogram. You need to get the white and black marker to overlap in the middle. This terns the image black and white. The other way is to tern the image to grey and then have the image to have small dots over the image. To do this go to image – made – greyscale then when the window pops up click on flatten and the hen the second window pops up click on discard. Then go to image – made – bitmap. Then change the bottom bar to halftone screen then OK. Then on the second window on the shape change it to round then OK. Then if needed to you can change the frequency of the dots and get the image to how you wont it.
