Grain extract mode - GIMP Beginners' Guide ep76 Video Lecture | A GIMP Guide for Beginners - Design Softwares

hi in this video we'll discuss next mode
here grain extract this mode is best
used with our layers not so much with
our paint tools now let's see how it's
calculated and what it's for
now the grain extract mode extracts the
film grain from a layer to create a new
layer that is pure grain and it can be
used for giving images and embossed
appearance this mode subtracts the pixel
value of the layer above from the pixel
value of the layer below and adds one to
eight so this is basically how it's
being calculated and how it can be used
and now let's see some examples we have
these two images here let's change the
upper layer to grain extract and you see
where we get let's switch back to normal
now let's turn on this layer I've
created here with a gradient and put
that layer on grain extract you see how
where we have black the image becomes
lighter and where we have white the
image becomes really dark let's see how
this works with this gradient with
different colors
you see how that works can change the
opacity
so that's it for this video see you in
the next one
