Is it worth the price?
Some images will be so difficult to cut out that it’s simply not practical to try, but Cutout 2018’s mask adjustment tools are so sophisticated that it can take a long time to reach that conclusion. It’s not conclusively better than Photoshop’s own tools.
Fluid Mask 3 costs more than Cutout 2018 and appears to do less – but it is faster and more effective. Perhaps the key difference versus Cutout 2018 is that you can see much more quickly whether an image is worth persevering with or not.
