How to convert to black / white only

Recommended Posts

...................................or simply increase the contrast.


If you use the convert to black and white tool it does not mean that literally. It just removes the colour content to give you a grayscale image. Depending on the subject, contrast and treatment it is a continuous tone picture from pure black to pure white with a range of grey tones inbetween. At least ideally.


That's what we did, and I thought still do, call a black and white image. Its certainly what photographers understand it to mean when talking about black and white photography.


A picture consisting of just black and white tones is what photographers would call a high contrast image, essentially a black on white silhouette, no greys. That would have been created in the good old days using something called lith film and/or a very high contrast printing paper grade. Hence my suggestion just to increase the contrast to remove the grey tones.
