In front of the introduction of Photoshop CS "picture filter" to add blue sky to the photos, if you think only add a blue sky is not enjoyable, below I add a blue sky and white clouds.
Open the picture with blue sky and white clouds. (as shown in figure I)
Select the tool panel "Magic Wand" and click on the Sky section. (as shown in Figure II)
Click on the Sky section, only select most of the sky, there are two ways to choose All the sky: First, hold down the "shift" button multiple times click on the rest of the sky, until the whole sky selected. Second, select the "Choose \ Select Similar" item in the menu bar and select the rest of the sky. (Figure III)
Either way, be aware of: first, it is best to enlarge the picture so that you can see clearly, the choice of the sky are selected, otherwise the junction with the Blue sky will be mixed unnatural; the second is the "magic wand" of "tolerance" not too big, too big may choose some should not be selected parts. If you choose a section that should not be selected, hold down the ALT key and use the Lasso tool on the tools panel to cancel the selection.
The sky is all selected. (as shown in Figure IV)
Open a picture of the blue sky and white clouds you want to add. (as shown in Figure V)
Click Select All on the "choose" menu. (as shown in Figure VI)
Click Copy from the Edit menu. (Figure Seven)
Return to the original picture (note: At this time your chosen Sky constituency still exists), click "Paste in" on the "Edit" menu. (Figure Eight)
Click "Paste into" after the blue sky White clouds are pasted into the new layer of the selection area, covering the original old sky. If you don't have a full selection, or you feel you need to adjust the white Cloud's position in the picture, you can select the free transform item in the Edit menu. (Figure Nine)
Use the mouse to pull the blue sky pictures around the small dots, adjust the picture size and position. Feel the adjustment satisfaction, with the mouse click on the tool Panel any button, a dialogue window, click "Application." (Figure 10)
If the sky is too bright or too dark, use the image \ Adjust \ level, move the slider to adjust the brightness, or adjust the opacity of the new layer on the layers panel to make the add part more integrated with the other parts. Satisfied with the new picture, click on the "Layer" menu of the "merge layer" item, a picture added blue sky white clouds on the success of PS. (Figure 11)
