hey guys welcome back thanks so much for joining me today we're going to look at
color casts
i'm trying a new tool today guys so please do let me know in the comments
below whether it has been helpful or not i hope that it is better than the
previous ones and we will soon see if you haven't already please do press
the subscribe button and click the bell icon the bell icon helps you as it gives
you a notification every single time i upload a video i upload every week and
sometimes more than that if i feel like it and if i have time
if you want to do me a solid i have recently become monetized which is the
weirdest thing in the world but that will make me be able to buy things like
this new piece of software to make the videos better so if you can please do
sit and watch the youtube adverts that would be great let's look at color
cast i've got a picture up here it is a one that you will already have seen
but i have left the color cast in so there
is casting on the dog over here we're gonna
go through three different ways of removing color
casts each one has its merits two are very very similar
and the third is my personal favorite if we're working with a dog that is not
black and white hence why i have chosen rioja rioja over
here does have some green coming through into the coat which is
reflected from the moss that was everywhere around here so we're
going to look at that we're also going to look at a couple of other images
and see where we go so the first tool is the one that most people will know it
is the desaturation method the desat method essentially you want to
be in your layers tab over here if you can't see layers
window layers a pop-up will come up click and
drag it over into this area when you've got that
you want to be down here in the adjustment layer section you want to
click on that which will bring up the
adjustment layer menu in here go for hue and saturation and that will
come up in the properties tab within the properties tab if you can't
see that again window properties click and drag
with the properties tab up there bring your saturation right down to
-100 makes it a lot easier to see and then you want to invert your mask so
click on the mask and then press command and i if
you have a windows computer that's going to be ctrl+i works exactly the
same so with this black layer we now need to
go ahead and paint so i'm going to press b on my keyboard
which will bring up the brush tool or click on the brush tool over there
it's very important that your palette is set to white and black
so if it isn't press d on your keyboard which will reset that to
black and white or white and black like i just said
because this is a black layer because we've inverted it
we need to go ahead and use white to make it
visible so on your keyboard to make your brush bigger
smaller hold down control and option on a
mac and then click and drag right makes it bigger left makes it
smaller up makes it softer and down makes it harder we've been here before
in the full edit video which i will link above
with a brush selected you want to make sure sorry that you run a 100 opacity so
if you're not say you're on 55 you can just you know
press 0 on your keyboard and that will bring
that up to 100. go ahead and paint i'm going to do this
very quickly and very roughly to cover the areas of the dog which have
cast would suggest with a dog with white on
it to go over any white areas with this brush tool
but what do we do when we get to somewhere like this over here where
the actual selection is a bit of her coat and then the white coat that's
going to be a bit of a trouble for us so we're just going to have to
paint and then work it out later so this is the area that had the most of the
casting we're just kind of going to go over that
and try and bring back bits that should not be desaturated like
the tongue for example shouldn't be desaturated
and very very roughly as we can see here just kind of brush over the area so now
we've got a very strange looking animal but if we click on the adjustment itself
can bring back up the saturation a bit and also drop the opacity
so we've kind of addressed it but this looks a bit strange because not
only have we removed the cast but we've removed
the colour as well and i mean to me that doesn't look particularly natural
so you would have to bring the opacity down to a point where it looks
natural-ish even then it's not brilliant and then
you've reintroduced the color differences into the coat
so that's method one works great for black and white dogs
not particularly great for anything with colour and therefore you also need to
know method number two and three method
number two is one that i've seen covered i personally have
seen i think on phlearn or pixin perfect's channel shout
out to them and you want to duplicate a layer or
just have a spare layer handy from your working layer and then
press command and i to invert the actual layer
and then we look very very strange but it's okay in this case you would repeat
the mask process by selecting a mask holding down
alt if you wanted to to get a black mask and then do exactly what we just did
because we've already done that i'm just going to copy it so i'm going to hold
down option and i'm going to click and drag
my mask click yes and now we look even stranger
but don't worry guys because then the next thing we do is we change the layer
style you can change it to hue or color both of them are very very
similar in fact i don't know if there even is a difference
in this situation i go with color and then if you bring your opacity down 50
is black and white so that's literally exactly the same as the desaturation
layer and if you bring it down further you're
essentially doing a lighter desaturation slightly more tonal
sensitive but has pretty much the same results
as the desat layer so um again great for black and white not
particularly good for anything else so what do you do and the next option
is to use your adjustment layer tool again go in there and click
photo filter as standard it will apply a warming filter
which is beautiful but not what we're doing here
very very very important to click on the layer
adjustment itself not the mask whilst doing the next
step if you don't do that and have the mask selected
you will not get very far after this point
so click on that and then click on the color
picker which comes up here so once you've clicked on the color picker
we now have a new little window that's come up
and within here we want to select the cast
now in most situations you would select something that has the cast on it but in
this case i've personally found that that's not
the best way because if you do that you also pull all of the color that you
want to keep out of it too so what i found is the
best way is to use your color picker and click on a color that is being cast
back so in this case the green of the moss
is being cast back once you've clicked on that
this will change and the color that comes up in new
is the color that you've just picked so within here you've got
some options you've got hue saturation and brilliance or brightness
you've got red green blue you've got cmyk you've got the hex code of that
color and you also have this little bit over
here which everybody ignores but it's super important
now a and b a and b are the color values to
find it in the in the color picker there so what we want to do is
invert them to invert them you literally make
the minus a positive and the positive or minus so in this case we've got minus
nine we're going to remove the minus to make it plus nine
we've got plus 44 we're going to add a minus to make it
minus 44. that makes it the complete inverse of the green
color to a certain level so click ok on that
that will give you this new color up here if you increase the density to no
more than 50% that would be advised things look
strange but hang on because it's pulling out the
green and the yellow so if we copy our layer mask again
holding down alt clicking on the layer mask that we want
putting that in there and clicking ok we have essentially
found a middle ground between the desat and the color cast
now it's still a little bit too strong for me you can click on your adjustment
itself pull the density down on the correction
there or you can bring your opacity down if
you wanted to if you've noticed it's left in the red
because blue doesn't handle red so what it actually does is it handles
kind of like a yeah kind of yellow kind of into the green because it's slightly
purple so uh yeah that what that's done is
that's taking the cast now if we zoom in on her face a little bit we can just
pull that down a touch more and we actually have if you look at the
colors involved in in here at this side they do mirror
quite similarly the colors of this side now there is still some little bits of
cast over here you can bring up your brush tool and
just brush that on there and what that does
is it's just targeting the color of the cast
so you can go on with a lighter brush you can change your opacity up and down
you can do whatever you want to do but it won't cover all of the colors
it's one of the other ways of doing it there is another way but we're not going
to cover that today because it's far too complicated
to be fair i never use it because it's just too much that involves using
channels to manipulate the colors that exist
within the image but this is one of the easiest ways so
with using this photo filter tool it takes slightly longer
but you do get a calmer and more realistic approach
you could marry that up with a hue/sat adjustment
and the hue/sat adjustment you could go ahead and just
i'm just going to remove it from this area here if i remove that just from
there the hue side is now just targeting this area here
i would use it with care not too heavy and that is a good finish i run this
image here we've got a heavy green cast on the underside of him
and we also have some weird colors going on in his face
but the green actually is one of the most powerful channels
so if i put the photo filter on there we have just
softened it off you could make that slightly more dense if you wanted to but
i would use with caution then you have this image here i've got
all three set up on this particular picture
so we've got the hue sat which pulls all colors out
of the coat it's also covering his ears but don't worry about that too much
at the moment then we've also got the inversion option
which does very very similar result to the hue/sat and then we've also got
the photo filter which is just a softer way
it's still quite severe but it's not as severe as a hue/sat or an inversion
so guys i mean that's it for today if you can please do press the subscribe
