Watch video: Cut out hair in Photoshop CC
While Lightroom, Adobe Camera Raw and other Raw editors have seen huge improvements over the past few years, they still can’t compare to Photoshop CC in terms of selection tools.
In this case, Photoshop blows away the competition with an array of hugely powerful commands that make it easy to cut out even complicated subjects, like our model here. Imagine trying to remove her original background by hand – it could take hours, maybe days to get rid of all the bits of background showing through the curly hairs. With Photoshop’s advanced selection tools, though, it takes mere minutes.
We’ll begin by employing a bit of machine learning. The ‘Select Subject’ command uses artificial intelligence to analyze image content and ascertain what your subject is, then attempts to select it. It won’t always be perfect, but it often gives you a great starting point to go on and further refine the selection. This brings us to the second stage of our selection process, and it’s here where we can eradicate all those pesky gaps between the hairs using the endlessly helpful Select and Mask command.
Once our cutout is perfect, we can drop in an entirely new background. The possibilities are endless; if we like, we could transport our subject to another continent, or another time period, or any scene we like. Alternatively, we might just want to change the mood of the image by altering the color of the background, or adding a blurred backdrop like this. Whatever you choose to do, the process is surprisingly quick – and much easier than you think…
01 Use Select Subject
Open your portrait image into Photoshop CC then go to Select > Select Subject. If it needs tweaking, grab the Quick Selection tool from the toolbar and either paint to select missing areas, or hold Alt and paint to subtract parts of the initial selection. The tool will seek out and snap onto edges as you paint.
02 Enter Select and Mask
Once you have a decent selection, you can go to Select > Select and Mask to improve it. Go to the View dropdown on the right and choose the view that offers the most contrast from the original backdrop. Here the ‘On Black’ view clearly shows us the nasty edges.
03 Increase the radius
This will better the selection along hard edges, like the body, but not the hair. Get the Refine Radius tool from the toolbar on the left and paint over the hair to up the radius. This helps the command seek out and exclude the parts of the background showing through the hair.
04 Check the hair
Check ‘Show Edge’ in the options to the right. This shows the radius, which is the area of refinement along the edge of the selection. Make sure the radius covers all the gaps and details. Then, uncheck ‘Show Edge’, choose Output: Layer Mask and then hit OK.
05 Replace the background
Grab the Move tool and drag the image to the second image of the blurred backdrop. Hit Cmd/Ctrl + T if you need to resize. The edges look rough in places, so next go to the Layers panel, right-click the black and white layer mask thumbnail, and choose Select and Mask.
06 Further refinements
This time check ‘Decontaminate Colors’, tweak the strength of the effect with the slider, then hit OK. This’ll create a new layer and improve the edges by bleeding in the colors of the hair. Finally, hit Cmd/Ctrl + Shift + Alt + E to create a brand new merged layer.
