0:05welcome back in our last video we
0:06covered Global adjustments edits made to
0:08an entire image when it comes time to
0:11finetune only a specific part of your
0:14photo that's where local adjustments
0:16come into play local adjustments let you
0:19apply targeted edits to specific areas
0:23without affecting the whole image now
0:25that we understand how adjustment layers
0:28work we can take that knowledge and
0:30apply it to make changes to select parts
0:34of our image instead of the entire image
0:37and this is what we call a local
0:39selection so for example maybe I think
0:42my foreground and my background or maybe
0:45my sky need to be changed independently
0:50of one another I can now do something
0:52like grab a selection tool and select my
0:56sky and when I add a brightness and
0:58contrast layer you're going to see The
1:00Mask my sky and my foreground are
1:03separated so when I change my brightness
1:06and contrast it's only going to change
1:09the selected area this is done in a
1:12non-destructive way because it's been
1:14applied with an adjustment layer on top
1:17of my background layer so let's make a
1:20few changes to the
1:22[Music]
1:24sky I'm also going to maybe change the
1:28Hue and saturation
1:30but instead of doing this to the whole
1:32image I'm going to add that clipping
1:41mask and now I can maybe make the guy a
1:44little Bluer and then I'll go back to my
1:46original layer or my background layer
1:48and maybe now I want to select the
1:51foreground and I can change the
1:53brightness and contrast of the
1:55foreground independently there are some
1:57builtin selection tools
2:00such as this one we find right here
2:02called select subject where when I push
2:05that it's going to find my tent for me
2:08or what it thinks is going to be the
2:10subject you can see that I can use an
2:13adjustment layer to affect this tent
2:16maybe we want to change the color of the
2:18tent if I go up to my menu bar where it
2:21says select there's some other options
2:24for me one being select sky so I don't
2:28if I have a complic ated Sky to select I
2:32can choose here it's going to analyze my
2:34image and it's going to select my sky so
2:37everything we've learned about
2:39adjustment layers while making Global
2:41adjustments I can continue to apply
2:44locally let's select the
2:47subject and let's say I want to make
2:50everything black and white except for
2:52this tent that'll really make the tent
2:55pop out if I choose black and white
2:56right now it's going to make the tent
2:59black black and white let's undo this
3:01Commander contrl Z and down here on my
3:04toolbar I can invert my selection now we
3:08see that everything except for the tent
3:10is selected I'll choose black and white
3:14now I have a colored tent with a black
3:16and white background let's take a look
3:18at some of the tools we use to make
3:20local adjustments to start us off there
3:23are three very similar looking tools
3:26one's called the spot healing brush tool
3:28one is called the remove tool and one is
3:30called the healing brush tool they all
3:33have this little
3:34band-aid and they work in similar ways
3:37but with slight
3:39variations you'll find that while
3:41retouching sometimes each scenario or a
3:44different scenario will call for a
3:47slightly different tool so let me show
3:49you how they all work um and then you
3:52can
3:53practice uh using them in your own
3:55images starting with the Spy healing
3:57brush tool
3:59this tool works by painting Loosely over
4:04top of something you want to remove
4:06letting go and it'll disappear now this
4:08is a type of AI that has existed for
4:12years and it's not called generative AI
4:15it is called content aware fill or
4:19content aware AI whereas generative AI
4:23would
4:24have analyzed this and
4:27recreated a new image
4:30using other similar images from Adobe
4:33stock content aware fill is going to
4:38analyze the image and steal pixels from
4:41around that area and then make that
4:45imperfection disappear although this
4:47image has improved you'll see that we
4:50have a problem that correction was
4:53destructive editing if I want to use
4:55these tools in a non-destructive way I'm
4:57simply going to make a cop Cy of this
5:00background layer I can right click on it
5:02and I can select duplicate or I could
5:05drag it down to this plus and now any
5:08changes that I make to this image I
5:11still have the original image underneath
5:13um the second tool I want to show you is
5:15called the remove tool the remove tool
5:18doesn't analyze the
5:20pixels and steal from over here and
5:23steal from over here and make something
5:25disappear the remove tool analyzes the
5:29image goes to Adobe stock and
5:32rebuilds this area using generative AI
5:36my healing brush tool works very
5:39similarly to my spot healing brush tool
5:43but instead of
5:45automatically selecting pixels from
5:48around my targeted area when I click
5:50you'll see it says option click to
5:53define a source point to be used to
5:56repair the image what does that mean it
5:59means that I manually have to select the
6:03area that I want to use to replace this
6:06by holding option or alt on my
6:09keyboard
6:11clicking and then when I go down here
6:13it's going to steal this area to paint
6:16over here a better way to watch this
6:18happen is if I hold option or alt
6:24here you'll see it Paints in that area
6:27so I need to choose where I'm saying
6:29sampling from and I might sample from
6:33here paint that here and it'll blend it
6:36a little bit another slight variation on
6:38this tool is called the patch tool and
6:41the patch tool works by drawing a circle
6:45around what you want to remove and then
6:48you click and drag to the area you want
6:50to use to replace it with so I wouldn't
6:53want to drag it down here I might drag
6:55it to here and let go and then I'll
6:59select by hitting command or control D
7:02the next tool we'll look at is called
7:04the Clone stamp tool the Clone stamp
7:07tool Works in a similar way where I have
7:10to select my source by holding option or
7:16alt and then I can
7:20paint and it will sample these pixels
7:23and paint them in another area let's
7:27undo that and I would want to the sample
7:30by holding option or Alt from an area
7:33like
7:36this and then I'll start painting here
7:40now if I go too far I'm going to start
7:43to repaint those pixels in a different
7:47area so if I'm working in a confined
7:51space I'm going to want to sample from
7:55here and paint a little bit and then I
7:58might resample and paint a little bit
8:01and resample and paint a little bit this
8:03tool works well for complicated areas
8:06like this where I might grab my clone
8:08stamp and sample from
8:11here and then
8:15paint to make this baseboard kind of
8:19continue and
8:21unbroken sample again paint
8:26again might sample from the cleanest are
8:29[Music]
8:31area start to paint over here and then
8:34one final tool we can use to do some
8:37retouching is actually just to grab a
8:40lasso
8:43tool that's a selection tool and just
8:46select an imperfect area and then I can
8:49go down to my contextual taskbar click
8:53generative fill and if I don't type
8:55anything in I can hit generate
8:59and then at the mercy of your internet
9:02speed Photoshop will use Adobe Firefly
9:05to analyze this image make the
9:07imperfection disappear and it will give
9:10me three different options let's use a
9:12different image to to look at these same
9:15tools and understand a little bit about
9:18the difference between content aware
9:20fill Ai and generative AI if I were to
9:25grab this spot healing
9:27brush and I'm going to use the brackets
9:29on my keyboard to make this a little
9:32bigger I could also go up here and
9:34change the size but if I was maybe to
9:39try to make something
9:43disappear using a Content aware fill
9:47AI it's not going to look great because
9:50it's going to sample from other parts of
9:53the image to try to rebuild um and make
9:57something disappear that's not the best
9:59tool for me if I use a similar tool that
10:02use uses generative AI to do the same
10:06thing instead this tool is going to
10:08analyze the image and then use Adobe
10:11stock images to rebuild and give me a
10:15much more successful result let's look
10:18at that one more way using a lasso
10:23tool I will make a rough
10:28selection around this subject hit
10:31generative fill type nothing when you
10:33type nothing you're indicating to the
10:36program that you want something to
10:38disappear let's hit
10:41generate and if I use this tool it'll
10:44give me three variations and I can
10:47select whichever one I think looks the
10:49best now if you're thinking well that
10:50tool works better I should just always
10:53use the remove tool that's not always
10:56the case you can see when I try to
10:58remove this card car using generative AI
11:02it will remove the car but often times
11:04it'll just replace it with another
11:07car um so if you just want to make one
11:10of these cars disappear instead of
11:14regenerating more cars you might use
11:17something
11:18like a spot healing brush
11:24Tool uh let's say that I want to add a
11:28sh depth of field effect or I want to
11:32draw more attention to my subject by
11:34making the background more
11:37blur I could do something like hit
11:40select subject and I'm going to go to
11:43where it says
11:44filter and I can choose
11:47blur and let's add a lens blur that's
11:50going to pull up this screen and now my
11:53subject is blurry I definitely don't
11:55want that so I'm going to
11:57invert that blur and I can turn up and
12:01make changes to how blurry I want the
12:04background to be now if you go too far
12:06it's going to not be very convincing so
12:09let's keep in mind less is more
12:12Photoshop also has a really cool tool
12:15called neural
12:17filters and when I select this these
12:20aren't automatically downloaded um
12:23you'll have to download each of these
12:26that you want to use but there are some
12:27really cool Tools in here like this
12:29photo restoration tool that's in beta
12:32where if I turn this on and I'm going to
12:34turn the scratch reduction way up I'm
12:38going to turn the enhancement way up and
12:40the enhanced face way up now that's
12:42going to be Overkill um but just to see
12:45what this does and what it accomplishes
12:48you can see that it
12:50enhances these images quite a bit so
12:52we'll turn those back down a little bit
12:55it looks that looks nicer and then I
12:58even have a colorized tool that with a
13:00click of a button it'll turn this from a
13:02black and white photo to a color photo
13:06and I can make adjustments to that we
13:08can find another pretty cool neural
13:11filter under landscape mixer and again
13:14this is in beta when but when I turn it
13:17on I can choose to change an image from
13:22Summer to Winter or I could change it to
13:26a sunset or I can apply some of
13:29these preset filters neural filters will
13:33also let me do cruel and hilarious
13:36things to my
13:38co-workers like turn on smart portrait
13:42and let's make zivic a little happier
13:45this was a photo taken at my wedding
13:48let's turn up his happiness now you can
13:52see that this is definitely a scenario
13:55where less is more if you change things
13:58too dramatic
13:59the results can be a little too much so
14:03let's just make that more of a smirk
14:06that's better I can click on my own face
14:08I'll turn up my facial age and turn
14:11myself into my father there he is and
14:14then you can also just do things like
14:18change the direction eyes are looking
14:21change the direction a head is facing
14:26you can also make changes like
14:29surprise or let's make you less angry
14:33I'm going to make a selection on this
14:41image and then by choosing select and
14:44mask I'm going to feather my selection
14:47this is going to kind of blur this Edge
14:50or this outline let's try 4.4 I'll hit
14:55okay and now I'll hit command command or
14:59contrl C move over to this image and hit
15:03command or contrl V and I've moved one
15:07mouth from one image to another image
15:10but they don't completely match up right
15:14the color balance is a little off if you
15:17blur your eyes this is a little bit more
15:20yellow orange red and this is a little
15:23bit more blue green so my options are to
15:28try to correct that color balance myself
15:31but I also have a neural filter called
15:34harmonization whereas if I turn
15:37harmonization on I can harmonize this
15:40new layer I've added with the background
15:43layer turn up the strength that did a
15:45pretty good job and then I can just make
15:48minor color adjustments to make it blend
15:51and look more realistic and I can now
15:54use Firefly Integrations to make local
15:57adjustments using generative AI so let's
16:01say if I were to grab a lasso tool and
16:03directly on my background layer I were
16:06to make a selection like this I'll
16:09select generative fill and I'll type
16:12hair when I select
16:15generate the program's going to assume I
16:18want hair added to this in the shape
16:22that I've made my selection so the
16:25selection you make is important when
16:27trying to get a desired result Sal so
16:29let's undo that and if I were to make a
16:31little bit more traditional of a
16:34selection and type hair you'll see it'll
16:37give me three very different Generations
16:40these are generated with masks created
16:43on their own layers so you can
16:47see it up that this is a non-destructive
16:51editing technique this tool works great
16:54for some things and not for others let
16:57me hold shift and add to this selection
17:00and if I were to type blue eyes what
17:03it's not going to be able to do for me
17:05is just change these eyes the color of
17:09these eyes to be blue eyes it's going to
17:11completely generate new eyes so keep in
17:14mind when you're retouching using tools
17:17like this that very quickly somebody's
17:21going to completely look like a
17:24different person this tool also works
17:26great for blending multiple images
17:29together so you can see I put two images
17:32on the same canvas as one layer and by
17:35selecting the
17:38middle selecting generative fill and
17:41leaving this blank and hitting generate
17:43you'll see that the program will blend
17:47these two images together giving me
17:51three variations there's one there's two
17:56and there's three they all look great so
17:58there's just just a few examples of the
18:00infinite amount of ways that you can
18:02make local adjustments using Adobe
18:05Photoshop so those are just a few ideas
18:08to get you started in making local
18:10adjustments take your own photos and
18:12adjust them in a way that makes sense to
18:14you and I'm looking forward to seeing
18:16what you make
