What's happening guys Dan Debenham here, welcome to just the fact Friday
today we are talking about removing noise from your images within Lightroom
let's get to it
Welcome back guys and as I said it is removing noise from an image within
Lightroom basically it's very very simple let's
get into Lightroom now and have a look at how that's done okay so we're in
Lightroom and we have our image in the develop module and what we're going to
do is we're going to be focusing on the detail section the drop-down box which
says detail on it we're not going to be colour correcting I've done that
already you can do it before or you can do it
after it's entirely up to you how that works
it's your call we're not gonna touch on colour correction today so what we're
basically gonna do is we're going to look at the noise reduction section of
Lightroom and effectively we don't need to do the sharpening we don't need to
mess about with radius mask in etc what we're just reducing is the noise
and the way that we do that is if you can see there's a little box above the
detail and slider bars and that is basically a zoomed in portion of the
image that you're looking at if you click on the little square the little
tiny little square it's like it looks like a sniper scope crosshair type thing
click on that and then click anywhere within your image that little zoomed in
box will will change to what you clicked on so that you can see what the noise
but it's like in the area so in effect what we're gonna do is we're gonna click
on that and we're going to just have a look at an area that we think has got
some noise and I think this area is a decent area to look at which is
basically on the extra-virgin olive oil that I've got in my kitchen and we'll
click on that and now we can see that there is some noise there from that what
we can do there is if we go down to the luminance section of our program we're
not going to do the sharpening which is going to look at the luminance the color
detail and smoothness if we hold down the Alt key and we'd be able to see just
the noise itself but before I do that if I just turn the turn the detail off you
can see that already at zero with nothing to do and nothing at all nothing
happening it's already tried to remove some of the noise even
at zero even with new touching nothing all its already tried to remove some of
that noise so turning it on and off you can see the noise gets even more or less
dependent on your image and so basically once we've done that and we turn it back
on again what we can do now is we can go to luminance hold down the Alt key and
that shows us just the noise and then from that point on we can move the
slider across to the right now we want to move across just just enough to the
point where the noise just starts to disappear
it's not about removing absolutely everything slide all the way to 100 and
you've finished basically this is a it's a balancing act between having the
acceptable amount of noise inside your image and a terrible amount of noise
which is overcompensated and you can't really tell what's going on so what we
do is we just move that about until we get it to where it's absolutely we're
absolutely happy with that and then we can zoom in a little bit further and
we can see exactly what's happening so we can see from the noise area here
which zoom straight in we can see that there is quite a bit of noise there and
we could just basically move that until the noise sort of disappears so let's do
that now so I'll just shift it on we press alt down and we move the slider
across and we can see the noise is just about to start to disappear bring it
back a little bit so with it now we can either you can either do it that way or
you can move the slider across just willy-nilly and you die so dog down so
that you can see visually what's going on or you can double click into the
number and just input a number that you think fits so in our case I think we're
going to go with 30 that looks around about right to me so we've removed for
nose a little bit from there the next thing we're gonna do is we're gonna do
the same with detail we're gonna move the detail in a little bit
pull the detail in just until the detail starts to change slightly it's the point
where there is just a little bit more it's very very fine details as with all
these things it's not about shifting stuff in 100% here 100% there it's very
minor detail changes just tweaking the image here and basically then we do the
same with contrast and we we keep missing you keep tweaking just
until we've got the image roughly about where we want it to be once we've done
that and we've got everything all sorted we can then just zoom back out of it
again here so we'll just get it to fit and then we can just switch the toggle
the detail on and off and we can see the difference between what we've what we've
made and what we haven't made if i if i zoom in a little bit more on the middle
bottle you'll be able to see that there is a drastic change in noise reduction
between that what it was and what it is now as you can see from a little square
a lot of noise is reduced it down drastically if you don't leave reduce it
down too far you just want to make sure that it is at an acceptable level where
your photo looks as good as it possibly can be and that is it basically that is
the whole the whole tutorial is very simple very quick very easy if you did
like it and it's a little useful please do like and subscribe below and I will
see you guys next week
