Gimp: How To Make The Background Black And White.😄

January 25, 2020


How to make the background black and white. When you have opened your image, right click
on the layer and add alpha channel. Duplicate the layer. Deselect the top layer by clicking on the
eye and select the bottom layer. Go to colors, colorize and slide the saturation
slider to zero. Click okay. Go to colors, brightness and contrast and
adjust the image if necessary. With this image I increased the contrast and
brightness to plus minus 50. If you do this, it is important to pay attention
to the black-and-white background and not to the object that eventually stay colored. Click preview and then okay. Select the top layer and make it visible again
by clicking the eye. Because this layer is on top, it covers the
bottom layer. Go to the toolbox and select the eraser tool. Pick a brush with a hard edge and increase
the size of the brush to plus-minus 700, depending on the size of your image. Now we can start erasing the biggest part
of the color of the top layer, so the black and white bottom layer becomes visible. We do this by left click and hold and then
move the eraser. If we erased a bit to much, we can hold the
Alt key and bring back the erased parts. When we come closer to the subject that has
to keep color, we can reduce the brush size and zoom in by clicking the Ctrl key and turning
the mouse wheel. When we hold the space bar, the eraser tool
changes into the move tool and we can move our image. Do not click, just move the mouse. Letting go of the space bar turns the move
tool back into the eraser tool. When we have made this second round of erasing,
we come to the really detailed part where we have to zoom in very much, maybe as far
as you can see the pixels and we use a much smaller brush. We can also make the brush bigger or smaller
by holding the left or the right bracket key. This process can by quiet time consuming,
so for the sake of the video we will speed up things and move on to the end of this process. So do not forget, use Alt when you have gone
to far with erasing and paint some color back. Use the space bar to move your image and the bracket keys to make your brush bigger or smaller. When we are finished and content with our
work, we can go to view, zoom and fit image to window to see the result. By clicking the eye of the top layer we can
see the black and white image with and without the color layer. Thank you so much for watching.
