The world is a messy imperfect place.
Often, there are flaws and blemishes in our mobile photos that distract the eye.
Sometimes these flaws are fatal and there is nothing that we can do to save our image.
But often spending a few minutes on image cleanup with a powerful tool like the Healing feature
in Snapseed from Google is all that it takes to remove a distracting blemish.
Let me show you what I mean with this photo of my niece.
I'll tap on the Tools and Filters icon down here in the lower right to get started
Since I already have this image open here in Snapseed's main window.
When the Tools and Filters menu appears I am going to jump right into the Healing Tool
which is this one here with the little band-aid symbols
Now when you look at this photo I hope that your eyes go first to my niece's eyes
and her smile.
She is a super cute little toddler but eventually, I think that your eyes will pick up
on three distracting elements in this portrait.
There's a warning label from her car seat over there on the far left.
All that text over there is super distracting.
On the right side of the screen, there is a green dot on her shirt.
Not a big deal, but as you will see in a minute, it's something in this scene that we don't need
and that pulls your attention away from her smile.
But the big problem here, for me at least, are those scratches on her cheeks.
Like all babies, no like all humans, we all have minor skin blemishes.
Scratches, pimples, freckles, everybody has something that they don't want on their face
and in this case that detracts from the story of this happy little girl.
So let's get rid of these things right now!
Since I have Snapseed's healing tool active all that I need to do is swipe my finger
over the elements that I want to remove.
I'll attack that label on the left first.
It might take a few swipes but by running my finger over that area
the label disappears!
What's happened here is that the program has created a pattern of new pixels
and stuck them over the top of the label.
When that plug of invented pixels blends well with the surrounding area the results are fantastic.
That was pretty great but there is a secret here.
The secret is that the Healing Brush size in Snapseed is tied to your zoom level.
For something big like that label I want Snapseed to replace a big area
so working on this image without zooming in is fine.
But if I try the same thing now, by swiping my finger across the screen over there on
the green dot on the right, the results will not be as convincing.
The problem is that Snapseed is creating too big a plug of invented pixels
and covering over too big an area.
Since it did not work well, I am going to tap on the Undo button
down there on the toolbar to take that mistake away.
This time I am going to press my thumb and forefinger against the screen and push them
away from each other to zoom in over the green stain.
As soon as I start to zoom in,
the navigator window automatically appears down there in the bottom left.
That box pops up so that I can tell where I am inside of the photo
and so that I can move around to another part of the image
without having to zoom all the way back out if I need to.
If I drag the little rectangle in the navigator window, I can reposition the image.
Now that I have zoomed in, when I swipe my finger over the green dot,
you will see that I am attacking this problem with a much smaller brush and a lot more precision.
Now, her shirt is nice and clean!
If I double tap on the navigator window, I can instantly zoom back out.
Now I am going to put my two fingers on the screen again and push them out
to zoom in over those scratches on her cheeks.
Do you notice how as I zoom in Snapseed shows you a little circle?
That circle is the size of the healing brush in relation to the image
and the more you zoom in the smaller and smaller the brush gets.
This is great when you need to do work with more and more precise.
Now, with two swipes over her skin, those scratches should disappear.
If I double tap in the navigator now or I use the pinch out move
with my thumb and forefinger at the same time, I can zoom all the way back out.
Let me tap the before and after button again so you can see what a cleaner stronger image
we have now that those extraneous distracting elements have been removed.
I am happy now, so I'll tap on the checkmark in the bottom right corner of the toolbar
to commit my work.
At this point I could tap save to create a nice clean copy of my original image
or I could bring out the tools and filters menu and pick another tool
if the image needed more work.
Now most tutorials on this tool would end here but I need to be honest with you.
Snapseed's healing tool is incredible when it works
but its not always going to work well for you.
I am going to bring up this image here from the Burnt Island lighthouse on the coast of Maine.
Let me show you with this image where the Healing tool is likely to be successful
and where it is likely to fail every time.
In this image, there are three things that I don't want.
It's pretty minor but there is a stump over there hiding in the bottom right shadows.
It doesn't really bother me
but I am going to use it to show you where the Healing Tool works well.
Let me zoom in here first so that you can see what I am talking about.
If I paint over this stump right now Snapseed will have an easy time creating a patch of
dark pixels to cover that area.
The patch that Snapseed creates matches the pattern of the area
that surrounded that stump really well.
Since our eyes can't detect a break in the pattern or some anomaly in that zone,
the stump disappears without a trace.
Let me scroll over to the other side of this image using the navigator window.
See that person there.
This is a photo from a workshop that I teach each fall on the coast of Maine
and that's one of my guests shooting their own photos.
That's great but I didn't really want my friend in this photo.
Well, I can swipe my finger over the top part of that person a few times
and the healing brush will work pretty well.
It works pretty well because the sky in this part of the image is basically flat white.
So Snapseed has a pretty easy time inventing a flat white plug that blends in well with what surrounds it.
As I work my way down though towards the ground things get less convincing.
The patches that Snapseed invents have a harder time blending in with the sky,
the horizon and the green grass
and a pattern that looks unnatural begins to appear.
If I keep attacking this area eventually I will get something that works
but it might take a bunch of brush strokes.
Let me zoom back out and I'll show you the before and after.
Not perfect but good enough I think for a cell phone image.
So now I am going to tap on the checkmark to commit these improvements.
I am going to return to the main screen so that you can see that the healing
that we just did is being recorded as a layer in Snapseed's stack.
See that little one over there at the top right?
If I press and hold my finger against the screen now, you can see this image
with that layer on and off, the before and after.
Notice that when I show the before image how the stacks counter says zero.
Ok, but the big flaw here obviously is that lens flare right on top of the lighthouse.
And that's a big problem because that flare happens to be on top of a really complex pattern.
Let me bring the tools and filters back up again and return to the healing tool one more time.
I am going to zoom in on the building to be a little more precise.
Now I'll paint over the flare with my finger but my expectations are pretty low.
Snapseed does a pretty good job on the lower part of the wall but the closer that we get
to that window frame the more things begin to fall apart.
The problem is that Snapseed needs to invent pixels that blend with the surrounding color
and a very well-defined pattern.
I can keep swiping away but eventually, I am going to call this one a failure.
Let me zoom back out so you can see what a mess I have kind of made.
That doesn't look convincing enough to me.
and it failed because the pattern that the program needs to match is just too complex.
Now I hate to end with failure but I don't want to give you false expectations either.
The best way to deal with something major like this lens flare is to shoot an image
in the field with my camera without the flaw!
But before I sign off, I do want to point something else out here.
Remember that stump and the extra person in this shot?
Removing those items worked pretty well and since I did them on a separate layer,
I can either hit cancel on the toolbar now or I can hit the checkmark to commit, without fear
of losing those improvements.
Let me hit commit just to show you what I mean.
Back here in the home screen, notice how the stacks counter now reads two?
That's because we have two separate healing layers.
And that's my big tip for you.
When you are faced with an image like this one where it's probable that the healing brush
is going to fail, my advice is to attack your problems using separate layers.
See now, I can step back down the layer of events all the way to the original if I want.
That would be like undoing everything.
Or I could go back to the layer that failed, the one where I tried to remove the flaw.
And then I could tap on that tiny little triangle on the right side
to bring out the options.
Now I can tap the trashcan icon on this layer to get rid of the mess that I made
while I was working on the lens flare, but without losing the improvements,
that I made on the other healing layer.
That's really my big lesson.
Take things in little chunks with the Healing tool.
Use separate layers whenever you think that the tool might fail and then if it does
you can reject the bad stuff, delete the failed layers,
without fear of losing your actual improvements.
I'll tap the back arrow in the top left to return to the main screen now.
Finally, I'll hit the save button to save my work.
It may not be perfect, but this picture is still a whole lot better than it was before.
