It can happen sometimes having to make prints black and white of a color image. The most correct way (and certainly faster) against those who pass the file to be printed is already in Grayscale.
One of the most popular techniques is definitely the “desaturation” (“Colors” – “Desaturation“), which is still very useful if we are operating only on a level, but we want to desaturate the’entire image. The steps will be few and simple, depart from this:
I nail levels are separated, it is not a jpg.
We select from the menu “Picture” – “Mode” – “Grayscale“.
And what follows is the vision of the same image with the same separate layers:
And here is the final result:
Mode “Grayscale” It is very useful if we have to export an image entirely in black and white, if instead it is necessary to yield in black and white levels of some, as already said, it is sufficient to use the filter “Desaturation” from the menu “Colors“.
