🎨 Advanced Techniques: Paths, Layer Masks, and Foreground Select Tools

Nick discusses advanced techniques for more detailed and precise background removal. The Paths Tool is a manual approach that involves creating points around the subject's edges for an accurate outline. The Layer Mask technique is suitable for images with high contrast and fine details like hair strands. It involves duplicating the layer, adjusting saturation and curves for a black and white image, inverting colors, and using the visible image as a mask for the original layer. Lastly, the Foreground Select Tool is introduced for subjects with fine details. It allows for a rough manual outline, brushing in the subject area, and inverting the selection to remove the background. Nick provides a link in the video description for a more thorough tutorial on these advanced techniques.
