Remove background in Photoshop CC 2018 | 3 Min Adobe

September 3, 2019


Hi and welcome to 3-Min Adobe. In
this episode, we’re going to have a look at removing the background from a photo
with a simple background. There will be a link in the description to a second
video which looks at removing the background from an image with a more
complex background, such as scenery or textures. Now, with a portrait open in
Photoshop – I’m going to first unlock the background here to make it a layer I can
work with and then I’m going to create a fill layer down here and select a solid
colour. Pick a bright colour that contrasts with the background you trying to remove.
This will make it easy to see the effect as we start to apply it. Now, I’m in the
“Essentials” workspace and I’m going to select the Eraser tool, or keyboard
shortcut “E”. Click and hold on the tool and select the “Background eraser tool”. In the tool options at the top here, we’re going to ignore the size for the moment.
I have the hardness set to 100%. This gives the edge of my tool hard
edges as opposed to soft, feathered edges. Of these sampling options – the next one
across – select the middle “Once” option. This means when you click, Photoshop
takes a sample of colour from where the crosshair is in the middle of your tool
and as long as you don’t lift your mouse button, it will only remove that.
“Continuous” – the first one – means if you accidentally go over another colour with
that crosshair, it will replace the stored sample and start removing the new colour instead. For “Limits”, if you have a look under his arm here, there’s also
some background that we’re going to try to remove. Now I’m going to make my
eraser tool very large and click just above the arm to sample and remove this
colour. Contiguous limits means it will only affect pixels of the sample color
that are touching each other. It won’t jump across his arm to erase the same
color down here, even though it’s in the eraser circle. If I switch this to discontiguous and click again, it means that it will jump across. This can be useful
for tree branches or other complex images where there are patches of colour
separate from each other. The “tolerance” is how much variation in the sampled
colour will be removed. A high tolerance means more will be removed, but this can
start removing good parts of the image as well. Finally, you can use the left and
right square bracket keys to adjust the size of your eraser easily. With an image like this it can be a good idea to lower your
tolerance, make your eraser smaller and zoom in to do areas around the face like
this. Then go wide with your settings again and clean up the rest of the image.
I’ll go ahead with these settings and do this now. When you’re done, go back and select just
the “Eraser” tool and go around the image to clean up any leftover bits. This will
erase anything that it touches, so be careful. You can now delete the fill
layer. With your “Selection” tool, you can move the image to another open project
as a layer, like this. Or, if you want to export it do it as a PNG file, to keep
that transparency in the background to load into new projects in the future.
Exporting as a JPEG will just fill in the transparency again, to make it a
white background. This has been 3-Min Adobe. Thanks for watching.
