Crop and clone in seconds
Tighten the composition Browse to clone_start.NEF. Grab the Crop tool. Set Aspect Ratio to Photo Ratio. Drag the corner handles to zoom in on the tower and loose some of the foreground shadow. Drag inside the crop window to place the tower at the left. When you’re happy with the composition, click Apply Ratio. Remove the shadow Use the Bird’s-Eye view to zoom in on the shadow, bottom-right. Click the Retouch Brush icon in the toolbar. In the Auto Retouch Brush panel, set Size to 60. Scribble over the unwanted shadow. The tool will automatically sample adjacent pixels and place them over the shadow to hide it. BUST THE DUST Scroll up to the top of the frame and paint over the sensor spots that are particularly noticeable in the clear blue sky. The Auto Retouch Brush will automatically sample adjacent patches of sky and paste it over the spots to seamlessly remove them from the scene.
Remove the post
Reduce the brush size to 25. Paint over the flag post. As the post is close to complex textures you may find that it is replaced by an unwanted brick texture from the nearby building. If this happens, choose Edit>Undo. Try changing the tip size and repainting the post until you get a better result.
