![]() Multiply or Overlay are good options, sometimes you can even Apply Image twice. Important: If your hair is light on a dark background then you need to invert some of this as far as when to Dodge/Burn and when to use Black/White. This will be what I work on until otherwise stated. I'm going to duplicate that channel and rename it to Hair Mask. Select the Channel with the most contrast in the fine outer hairs. Note: I'm going to be doing the body in a separate layer so I'll be ignoring it for most of this tutorial until the final few steps This is if you want to get higher quality results. Graphic Design Stack Exchange: How to cut how hair accurately Advanced hair extraction tutorialįirst off, plugins and simpler methods are available. If you need the detail, create a hair mask as Ryan shows. If your final result is going to be scaled down (for web viewing, for example) I'd just use this approach. ![]() Which isn't as good as Ryan's, but can take less than a minute and requires very little care, and is noticeably better than the Paint Bucket Fill approach. Make sure "feather edges" is selected with a relatively high radius.Īnd then use the curves tool again, this time even more aggressively (since none of the actual subject should be affected): This leaves the corners a little bit of a bluish off-white, so repeat the fuzzy select, clicking in a corner with a much lower threshold (10, 11, something like that). and draw a curve like this, smashing all of the extreme almost-white highlights to pure white, and bringing up the rest very aggressively: It's easier to see what you're doing in logarithmic view mode. Then, Grow that selection - the goal is to cover all of the places where gray shows through the hair but not get too much of the face: The example is in Gimp, but uses tools that you should be able to find in pretty much any program.įirst, use the "magic wand" selection tool with a very broad threshold (here, about 60): However, I want to show how you can get pretty good quick results with just fuzzy select and the Curves tool rather than paint bucket. I don't have Photoshop, so I'm not the best-suited to answer that.įor an alternate way to get the result you want, Ryan's answer is great and I definitely recommend that masking approach. Changing this the tool's mode to Luminosity may get you what you want. That's why you get the blue or the gray→gray effect. The color replacement tool isn't working for you because its default mode is "Color", which changes hue and saturation, but not luminosity (brightness/value). How can I change background color to pure white? Second method changes colors more accurately (without hair cuttings), but colors are "transparent". How to change background color properly? First method is quite untidy. Instead of real blue (dark) color I get this kind of transparent, unsaturated blue. I will show it on the example of Blue color (grey changed to grey is unnoticeable). ![]() This "white" color is kind of transparent or extremely unsaturated. Using Eyedropper Tool I selected background color and set white for replacement:īut it replaces background color to grey (not white). Secondly, I switched to Color Replacement Tool. Background-to-hair transition bounds are sharp. I selected background area with it and then applied Paint Bucket Tool. I need to change background color from grey to pure white įirstly, I did it using Magic Wand Tool. I have a picture (File format: JPEG | Сolor depth: 24):
