POWERFUL Photoshop Filter To INSTANTLY REMOVE Ugly JPEG Compression Artifacts

January 23, 2020

Have you ever seen those ugly blocky, pixelated
artifacts that completely ruin your old JPEG images? In this video, I’m going to teach you how
to use a powerful Photoshop filter to instantly remove compression artifacts
from your JPEG images. Hi, I’m Jesus Ramirez,
from the Photoshop Training Channel. This is going to be a fun and informational
tutorial, so make sure that you stick around til the very end so that you catch all the
tips and tricks in this video. If you’re new to the channel, be sure to click
on that subscribe button now so that you don’t miss any future Photoshop tutorials. Okay, let’s get right to it. This is the image that I’m going to work with,
it’s a photo of Frida the cat. Everybody say hi to Frida. I’m a really big
cat person and you probably have noticed that I use a lot of cats in my tutorials. But anyway, if you want to follow along with
this image, I’ll place a link to it right below in the description. First, let me just explain the problem. I’m going to press the Z key on the keyboard
to select the zoom tool and I’m going to zoom in so that you can see the artifacts that
were created by the JPEG compression on this image. I’m sure that you can see the blocks that
create the pixelation on this image, this is caused by saving a JPEG with low quality
settings or by saving a JPEG over-and-over again; Since every time you save a JPEG you compress
it just a little more. I’m sure that you have seen this before and if you want to fix this
in Photoshop, let me show you what to do. First, go into the background and make sure
you unlock it and right-click and convert it into a smart object. We’re going to apply
several filters and we want to have the ability to edit them. A smart object is a container that can hold
one or more layers and it allows you to apply adjustments, distortions, filters and transformations
non-destructively, which means you can always come back and edit them. Go into Filter and go down into the noise
option and select, Reduce Noise. This will bring up this window, where Photoshop
will immediately apply a blur to smooth out any noise. And notice the preview box here, make sure
that you enable it so that you can actually see this happening on your actual image. By the way, here’s a quick keyboard shortcut
that you may not know. On any window that has the preview checkbox,
if you press the P key on the keyboard you will enable or disable that checkbox, so that’s
P for preview. So use that keyboard shortcut and then you
can see like a quick before and after as your working on any window in Photoshop that has
the preview checkbox. You can then use the sliders found in this
window to control how the algorithm blurs the image to remove any noise. First, you have the strength slider, this
slider allows you to control the amount of luminance noise reduction applied to the image
channels. I know that sounds confusing, but basically
you’re blurring the image on all the channels at the same time. If you are an advanced user and you want to
use channels, you can use the Advanced Option and from here, you can adjust the blur per
channel basis. So you’re only blurring the red channel or
only blurring the green channel, or only blurring the blue channel and what type of strength
and preserved detail amount you have. But in this case we don’t need to do all of
that, we’re just going to stick with the basic, so we’re only going to deal with all the channels
at the same time. So you can use this slider to control the
amount of blurriness that happens with the noise reduction. Then you have the preserve Detail slider,
which controls how much detail you keep, especially in areas that have hair or textured objects. In this case, we have fur, so you have to
use this slider accordingly to see how it affects the rest of the image. Obviously, you can’t bump it up too much because
you’ll actually make the pixelation stronger and you can’t come down too low because the
image will be very blurry. So you have to play around with the settings
and see what gives you a good result in your image. So in this image, maybe a setting of
about 15 will work. You could also zoom in on this window to see
different parts of the image. So I’ll zoom in more and I can look at the image and see
how these settings are affecting it. Another very common problem with images that
have been compressed too much is that colors will tend to bleed, like you can see colors
bleeding throughout the image. And actually, you can’t really see it now
because it’s already been reduced, but if you look at the reduce color noise, I have
a pretty high setting, but if I bring that down to zero, you’ll see that the noise comes
back. You can see a lot of noise in these areas. See that? So make sure that you adjust
the reduce color noise accordingly to remove that extra colored noise. See that, that’s
before and after. It just smooths out these blotches of color. Next we have a Sharpening slider to sharpen
the detail. Let me zoom out a little bit so that we can see how that works. If I increase
it to 100%, you’ll see that the image gets much sharper but it creates other issues and
of course if I reduce it to 0%, the image might be a little too soft. So again, adjust this slider accordingly so
that you can get a good result on your image. Notice that I’m not really giving you
what percentages to use because it just wouldn’t be valuable to you. The values depend on the image that you have.
So, you can use the values that I use
as a starting point if you like, but at the end
you’ll have to use whatever values work best for your image. So this is going to be a very important checkbox,
remove JPEG artifact. This will remove these lines that you see here. The algorithm will
try to determine what artifacts are created by the JPEG compression. So watch what happens as soon as I check this
checkbox here. See how it smoothed out all those lines? So now we don’t really see any of that JPEG
compression, which is great and is exactly what we want. Next, I’m going to press OK to apply these
adjustments and I’ll pan over to this area. In the Layers panel, you’ll see the Smart
Filters. If I click on this eye icon you’ll see the before and I’ll click again so you
can see the after. So as you can see, it’s a massive improvement. I’ll double click on a Hand tool to fit the
image to screen and now I’m going to apply another filter to further enhance this image. I’m going to go into Filter>Camera Raw Filter.
With the Camera Raw Filter, I can do so many cool things to this photo. For example, I can maybe make the shadows
a little bit darker and increase the contrast just to hide some of those imperfections. I can also increase the texture to make the
fur standout a little bit. And I can increase clarity, which is contrast on edge pixels. And the image is a little desaturated, so
I can use either the Saturation slider or the Vibrance slider to add saturation. The difference is that Saturation just bumps
up the saturation in all pixels equally, while Vibrance only increases the saturation of
pixels that don’t have a lot of saturation and it also protects skin tones. So it’s a great slider to use, especially
in portraits. In this case I can bump it up, I really want
these colors to standout. And I’m not getting the oranges that I really
want behind the cat. So what you can do in a situation like this
is go into the HSL tab, which allows you to control the hue, saturation and lightness
of individual colors. For example, with the oranges, you can slide
this slider to control the luminance because we’re in the luminance tab. Or you could switch over into the saturation
tab and control the saturation of the oranges which will make the orange behind the cat
pop. Next, I’m going to go into the detail tab
and I’m going to increase the sharpening. When I sharpen, I do an overall sharpen in
the image and usually that’s not the best thing to do. That’s why we have the Masking slider. With
the masking slider, Photoshop will find the edges of the image and only apply the sharpening
to those edges. But if I simply drag on the slider, you really can’t tell what’s going
on. If you want a visual representation of what’s
going on, you can hold the Alt key on Windows, that’s the Option key on the Mac, and click. Everything will turn white. So you can think of this as a Layer Mask,
white reveals, black conceals. If I drag to the right, you’ll notice that
Photoshop will start finding edges and we only get white on those edges, so that means
that the effect will only be on the white areas that you see. So maybe we just want the effect on the cat,
not so much on the background, so this might be a good setting here and I can just release. Before and after, a subtle effect but I think
it works. And finally, I’m going to zoom in just to
show you one other thing. We were blurring the background to try to
remove the pixelation, so that means that we have a lot of soft pixels. So I’m going to go into the effects tab and
just increase the grain just a little bit. It helps the image regain some of that film
quality. It doesn’t look so computer-generated because of the blur, so I think that adding
grain always helps. I’m going to press OK and these are my results. Let me zoom in so that you can see. I’m going to click on this eye icon to hide
the Smart Filters. Before, notice all the artifacts that are found in the image caused
by the JPEG compression. And here’s the after, notice how they’re all
gone and you can’t even see them. The image looks much, much better. So I hope that this technique helps you out
with your old images. Let me know down in the comments below if
you’re familiar with this technique and if you have found some success with it. And of course, if you’re new to the Photoshop

    The reduce noise filter does NOTHING for me. If I slide from 0 to 100% I can see just a little bit of difference. If I check the reduce jpeg artifact option nothing changes at all. This is on any picture that I try with… I'm using CC 21.0.2

    Unfortunately its a compromise where you don't remove JPEG artifacts, you replaced them with blurry results. There is no free lunch. Only way to get around this is reconstructing missing detials with some kind of AI tool. So far the only one that is close to doing that but not perfect would be JPEG2RAW AI from TopazLab. But its not perfect. Better than the photoshop version though.

    Hey, nice tutorial, as always.
    Did you already tried the Diffusion – Anisotropic filter? It works very good too, specially if the compression artifacts are moderate.

    Is it important to use the reduce noise filter before the camera raw filter? I've used the workflow you're demonstrating here recently with the exception of it being in reverse order.

    These tutorials are pure gold, very helpful and needed. I always used the reduce noise filter but never had these outputs, you are just on another level. I always learn new tricks when I watch your videos.

    Thank you, Jesรนs — I ALWAYS learn something from your tutorials, even the basic ones! Question/Request @ ~3:00: I am trying to think of a situation where one might want to reduce noise selectively by channel. Would you show us a practical use for that option in the Reduce Noise dialogue box? Thanks, again!
