Shutter blending step by step – steps 10-12

10 Refine the selection

Continue painting to select the handlebars and the top part of the bike. Hold Alt and paint to subtract areas from the selection if the tool goes wrong. Next, click the Refine Edge button in the tool options. Set Radius to 1.9, Smooth to 7, and Shift Edge to -25. Change Output To to Selection and click OK.

11 Tidy the edges

Go to Select>Inverse to invert the selection. Now any painting will be restricted to the area outside the cyclist. Highlight the Mask Thumbnail on the top layer. Grab the Brush tool and set colour to black, then paint to hide the layer and tidy the edges around the cyclist.

12 Tidy the mask

Press Ctrl/Cmd+D to deselect, then zoom in close to the handlebars. Paint precisely with white and black to reveal the bike frame, handles and wires and paint black to hide the gaps where the background is visible. Press X to quickly switch between black and white.
