How to use the history brush in photoshop [4K]

hey folks Gary Bradley here from Creative
Frontiers and in this video I’m gonna show you how you can undo in a brush tip
that’s right if this is your first time visiting and you want to learn best
practice techniques to create killer artwork then start now by subscribing
and clicking the Bell so you don’t miss a thing so if you make edits and you
realize that one portion isn’t right you can undo that region and with the help
of the history panel and the history brush that is possible again with a lot
of things like this there’s a cool things to be aware of so I’m going to
take you through the history panel and also a couple of preferences as well so
the image in front of us that I’ve got here to work with it started out life as
six images that I sticks together with photo merge and we now have this nice
panorama so this Beach here is a sunny three Cliff’s Bay in Wales and you’ll
notice that if I pick up the zoom tool and zoom in because it’s quite a big
image I can zoom in we can see the people on the beach in there now I’m
going to remove some of the tourists along the beach in then just to empty
out little bit so again you know kind of thing is I go to the tools panel pick up
my Spot Healing Brush tool and then you’ll want to make sure that your brush
tip is big enough to remove a person with a left click for example you don’t
want the brush tip to be too big so you’ve got there to the brush size in
there so so we’re doing 20 and 25 pixels for this image I can still hover my
cursor outside of there and see what the bush size is like and I’m happy with
that so I’ll press return want to make sure that the option for type what type
of edit I want to make is content-aware and then from here quite literally
I’ll just hover over a person and then left click and then remove them like so
so the dark black line in there and when I click and hold down the mouse and drag
if I’ve got a region to remove is showing you the parts where the brush
will affect the image of the mouse then it removes that person click and drag
across there and I can keep working through and applying this so it you know
it’s nice and relatively effortless is the Spot Healing Brush tool and then
what Photoshop sets are doing is you can never use the Spot Healing Brush tool
before when you click book shop will then decide very very quickly what other
parts of the image match the region and it uses and decides what to replace it
with and so all you have to do is click and drag and remove be
if I do this one as well you tend to find sometimes if the details are little
bit we’ll see you might have to click a few times you might get a repeating
pattern sometimes if you can’t remove that repeating pattern your best to
switch to the clone stamp tool or something like that so I think we’ve
removed a few people from there that’s probably enough for now and then someone
turns around and says to you do you know I hate prop I think you’d look better
with some some people on the beach in there at least not completely emptied
out and you think you know yeah suppose you’re right and then you
go to the layers panel and you realize oh no I didn’t create an extra layer to
put those edits in and I’ve permanently done that to the background layer so if
I leave my layers panel Felicio an on screen here what you can
do to rescue the situation is to go to the window menu at stop the screen good
analyst district you know probably history panel and then you’ll notice
that there is a list of edits in here so all of these in here are my Spot Healing
Brush tool edits if I drag and pull that panel down you’ll notice that the latest
edit that I’ve made and the current view of the file is right here it’s
highlighted and darker gray color and that’s where I am in the file I could
have for wanted to click and it’ll take me back steps in the file so as I keep
clicking on each of the worded steps in there it will take me back to a point in
time now that will also undo everything in the image so anything I did in the
image on these specific steps it changes so you can go back in there and you can
click on them and you can undo so in from one very very basic point of view
the history panel is slightly more intuitive than just going to the Edit
menu and choosing undo state change or to toggle last day or to redo something
you can see all of your edits in that list in there all the way back to the
point where you first opened up the file so all your edits are in the lower half
going down what Photoshop does is it creates things called snapshots at the
top I’ve been here so when you first open up the file Photoshop will create a
snapshot of what that image looks like in that point in time in there in this
case it’s called Coast panel oh one PSD you can see there the very first thing
is that I opened up the file so couple of things to be
aware of if I’m then lucky near thinking right so yeah I I probably get rid of
these people might want to keep these people here they’re just behind the
rocks that’s that’s fine introduce us and more people in there so and what I’d
have to do then is go down the list and click in there like so I know that those
people were obviously in the image when I first opened it up so as long as I in
here click on one of these early steps that dictates which point I will go back
in time so I know this is like getting Doc’s DeLorean and then punching in
October the 15th 1985 I think it was October the 15th anyway I digress going
back in time and doing something back in history and now the the way that you do
that is you will have to use the history brush tool so you can tap the Y key and
the keyboard it will give you either the history brush tool or the Irish rebus
Joe it’s got to be the history brush tool and again my brush tipping is
really big so I’m going to go and change the size of that back down to something
smaller like 22 pixels press return and then leave all the
options as they are at the top and then from here you don’t click on the steps
in here you just tell Photoshop that you want to use the painting tool the the
history brush tool to paint back to this point here when we first opened up the
file so my highlighting down the bottom in
here all the other edits are present and I click and hold down the mouse and drag
across that region and it undoes that region and only that bit of the region
region of the image with the history brush tool how cool is that
so if you do forget to do the thing that you ought to do which is in the layers
panel when you’re healing and retouching is to create an extra layer then if all
the edits are done in the background layer for example then you can use the
history panel to get back and undo those things and you’ll notice in here even
the history brush tool is a state in there that you can change if I go back a
step and that’s just like doing undo but I’m just clicking in the list in there
like so so yeah there is an element of that in there you can go back to your
history state in there go down to the bottom and then if I click and drag
across these people in here obviously that has no effect because they were
already in the file but if I go back to my Spot Healing Brush tool and then
click and drag across them I can remove them and I can click and drag and
these people as well so a really neat way to be able to work in there the
thing that you ought to really be aware of which is which is it is a problem if
I’m now thinking right I’ll go back then and I want to want to reveal a couple of
people from over here though some people down here okay so I’ll click in here go
back in time and oh there we are there’s probably one of the first things
that I did I remove these people I’m gonna put these people back in again
so I’ll click back down my list in there notice that where I am at this moment in
time is Spot Healing Brush tool halfway down that list the future has not yet
been written it’s there but it hasn’t happened I’ve gone back in time so these
are potential steps that I have made watch what happens then if I decide that
I want to heal and retouch something else in the image so if I go back up
here and let’s say for example remove remove that person wearing yellow up
there so look at the history panel when I hover my cursor over this region and
click and hold down the mouse and drag when I let go the mouse look at the
history it all disappears so you need to be very careful when you’re working with
the history panel if you do click back in the steps in there that is actually
something you want to do but I have lost all the other edits inside of there now
so any of the other people that I hid they have all now been revealed in there
because I’ve lost those steps it’s something to watch out for now if you
want to kind of avoid that situation then you can go to the history panel
click on the panel flight menu and you can go to history options so by default
Photoshop will create a snapshot which is just two here at the top of there
when you open up the file and you can choose to automatically create a new
snapshot when you say the four so if I’ve worked in this file now if I do a
file save or save as then it will create another snapshot underneath the previous
one in there now I’m not bothered about that but I do want to turn on allow
nonlinear history and then the other thing you can do is you can name any
snapshots that you make so you can actually make your own manual snapshots
if you want to create a snapshot of what the file looks like at any part that
editing process you can do that yourself so I’m going to turn that on because it
will allow you – name it otherwise it’ll just call it
snapshot one not two or three you can also make layer visibility changes part
of the options in the list in here I’m not bothered about that so I leave it
turned off and then I’ll click OK so again going back to this theory that if
I want to go back now and redo those edits and hide those people dragging
along there and redo that that is absolutely fine in there so I’m just
removing these people along here making some further edits in there like so so
all happy with that if I now go back in time back to the point like I did
earlier those people have revealed in there so I’m thinking oh yep that’s
where they were if I click a little bit lower down again now if I want to if I’m
clicking in here if I don’t click all the way down the list in there and do
what I did last time this occasion when I go back to my history brush tool over
here if I hover over this region and click and hold down the mouse look what
happens the history panel so I reveal those people it takes you right down to
the bottom of the history panel it actually states the history brush has
one of those steps but you don’t lose the history in there so it’s an
important thing to note is that that’s a way of accidentally not removing the
future in your in your history panel in there um but to be clear um if I click
back in here it doesn’t remove those people doesn’t change that history stay
in here for everything that preceded it it only updates the file in this step in
here so they are still hidden in the previous steps so it isn’t as though you
can go right up to the top of here and then reveal somebody and they’ll then
all of a sudden be revealed in all the other steps slow down they’re not so
it’s an important distinction to make inside of there if at this point now I
think yep do you know what I’m gonna do a snapshot I’ll go down to the camera
icon down here click on that call it a name and I’ll call this stage one I’ll
create snapshot of the full document not particular merge layer or a current
layer in there but for the full document and then click OK notice now that it has
created that snapshot for me so if I’m working along in here I know that at
this point all these people have been removed I can carry on editing pick up
my spot healing brush tool and move these people from the beach along
here again and from along here I know now that I can scroll back up the list
not clicking on each step but if I click on snapshot one which is called stage
one because I named it and then go back to the history brush tool I know that in
this region here there were some people I can put them back in again so that’s
how you can create your own snapshot and paint back to it as well which is pretty
neat so yeah there are a few things to be aware of with history panel but it
will essentially allow you to paint back in time and not undo the whole image um
the other button down the bottom in there and will allow you to create a
duplicate of your image as well so if you ever wanted to create a second
version of your image when I click on that there you go
notice in here it will read history brush in there and it creates that
generic name for the temporary file in there so this is a copy as the file was
that whatever pointing time it was in the previous version so it creates a
duplicate now I don’t need that idea so I’m gonna close it down but that’s what
that button does down the bottom creates a duplicate image of what wherever the
files are you working at the moment in time now the history panel will show you
last 50 steps in there if you want to have more you can you can have a lot
more but the more steps you allow Photoshop to show in the history panel
it does burden the machine with more work to do and remember so if I go to
Photoshop CC down to preferences and then choose performance and you can find
this by on a PC by going to edit and then choosing preferences under
performance then you’ll notice that over here we have history States so by
default it’s 50 in the later versions of Photoshop you can click a little drop
down arrow in there and you can get all the way up to 1000 steps in there but as
I say it’s lovely to have that many steps to go back to but it will burden
the hard drive and the graphics processing and all those are the kind of
things as well so may well affect performance and you probably find that
somewhere between 50 and hundred steps will probably be enough for a lot of
people I’m going to knock that back 250 in their cache levels right so what this
means is that in Photoshop your image will be broken down into in
visible tiles so if I make an edit to the very lower right corner of the image
Photoshop doesn’t need to redraw the image to show me that edit take shape on
screen or to go back in time so it really is all just about trying to save
the burden of the computer having to redraw the the entire image every time
you make an edit it only updates a certain quadrant or a certain square of
your image in there so what you can do in here is you can increase if you’ve
got a really big image you can increase the number of cache levels in there
which will subdivide invisibly almost your image into smaller chunks and so
saving and updating those kind of things should be quicker but for file that’s
lower in size and things you could drop the cache levels back down to a lower
figure in there that’s what that means so I’m going to set that back to 4 in
there and with that done then that’s pretty much it for the options I’ll
click OK in there and last thing I want to show you then is that the history
panel will only show you steps in here for the active open document and that
will not live with the file frame the entire process once I close this
document down so if I now go to file and choose save as and if I say this is
Beach panel 2 and then click on save if I then choose to close this document
down so again just so you can see everything in this panel all of the
edits and the snapshots at the top if I close this document down go back to file
and then choose open and then open up power Coast pano 2 and then choose open
take a look at what happens in the history panel so you start all of the
way back to square one again so the snapshot the top is what the
image looks like now and any edits I make are for this session and this
session only so yeah the history panel is great a couple of things to be aware
of but it essentially allows you to undo in a brush tip with history panel and
the history if you liked the video please give a
