Clean up image and unify colors using GIMP 2.8 - Subscribers Q&A 4 Video

hi I got a question from a viewer and he
wants to know how to remove pixels like
this here that sometimes appear when you
have a low resolution image or graphic
and also how to unify colors if i zoom
in here in the bus you'll see that not
all the pixels are completely black and
this also in the gray here you see we
have all shades all kinds of shades of
grey and how we can unify for example
this graphic to turn it completely black
and also remove these necessary pixels
around it now I'm going to start by
telling you that I noticed that you open
new tools options by double-clicking on
a tool so I recommend when you have them
open like a floating dialog like this
just click and drag them over here and
dock them so you have your tools options
and it's much easier to work like this
and also you can reset you to options
from this menu over here we set all
tools options or you can use this one
over here to reset the selected tool
options and you see now you can go
through different tools and you see your
option here next you think that you need
to use the eraser tool to remove these
pixels but the easier way is to use the
brush tool before that grab the color
picker tool and select the color the
background in this case is white and
this is why it's better to use the brush
tool because the color the background
can be something else and you pick that
color and it will appear here it will be
set like a foreground color then you go
to the brush tool select a brush and
then adjust the size of the brush and
then start painting with this white
color to remove these pixels and when
you go to an area that you need to make
the brush smaller just use this or here
to make the word smaller and just paint
around
move these necessary pixels and there
isn't faster way to do this because the
pixels are very similar cover to the
pixels of the graphic and if you try to
select them you also select pixels from
the graphic so you need to do this
manually using the brush tool and I'm
going to pulse here to go around graphic
so I already painted around the graphic
removed these unnecessary pixels now the
next thing I'm going to do is grab the
Select by color tool adjust the
threshold here to 100 and this number
you may need to experiment with I'm also
going to click this option to reset my
foreground and background colors then
I'm going to click on the graphic and
this will make a selection now go to the
Select menu and select shrink by just
one pixel then I'll go to select feather
with two pixels and I'm going to use the
Edit fill with foreground color option
then ctrl shift a to deselect or you can
go to the Select menu and choose the
option now and you see that we managed
to clean up the image and also turn the
graphic completely black you see that
the graphic doesn't look very good
reason is that it's zoomed in on five
hundred and fifty percent but if I
select the original size a hundred
percent you see the graphic looks very
good and if you want to upscale the
image this is a completely different
topic
turning small image into big image and
keeping quality it's something extremely
difficult it's actually easier to
recreate this graphic for example an in
scape which is a free vector graphics
editor then trying to upscale it and
keep the quality I am trying to figure
out a way to do that and get a very good
result but so far I got nothing we're
sharing there are a lot of filters and
different tricks that you can use but
none of them actually give satisfying
results this is why I like vector
graphics because
a vector graphic can scale it up as much
as you want never loses quality but when
it comes to pixels upscaling it's not a
good idea so that's it for this video I
hope that it was useful if it was
