Lesson 43

呈現天空的面貌

本課程在加強對天空的認知，將它當成是照片中的一個元素，並且訓練在拍攝天空時，如何正確的曝光。

如果天空與地面的明暗反差太大，可以利用減光鏡來減少天空的曝光，或是利用補光工具來補足地面的光源，或是乾脆只針對天空測光，而使地面地面的曝光不足。

正中午太陽光線很強，直接對準天空測光

Lens: 18-70mm F/3.5-4.5 G
Focal Length: 18mm
Exposure Mode: Aperture Priority
Metering Mode: Multi-Pattern
1/500 sec - F/11
Exposure Comp.: 0 EV
Sensitivity: ISO 200
Optimize Image: Vivid
White Balance: Cloudy
AF Mode: AF-S

也是在接近中午時分，直接對天空測光

Lens: 18-70mm F/3.5-4.5 G
Focal Length: 18mm
Exposure Mode: Aperture Priority
Metering Mode: Multi-Pattern
1/1600 sec - F/5
Exposure Comp.: 0 EV
Sensitivity: ISO 200
Optimize Image: Vivid
White Balance: Cloudy
AF Mode: AF-S

太陽快要下山時分，直接對天空測光，前景的屋簷一片黑暗，然而因為主題是天空，屋簷與遠處的山稜線成了現成的框架

Lens: 18-70mm F/3.5-4.5 G
Focal Length: 24mm
Exposure Mode: Aperture Priority
Metering Mode: Multi-Pattern
1/250 sec - F/11
Exposure Comp.: -0.7 EV
Sensitivity: ISO 200
Optimize Image: Vivid
White Balance: Shade
AF Mode: AF-S

為了強調天空的彩霞，直接對準天空的雲測光

Lens: 18-70mm F/3.5-4.5 G
Focal Length: 25mm
Exposure Mode: Aperture Priority
Metering Mode: Multi-Pattern
1/160 sec - F/11
Exposure Comp.: -0.3 EV
Sensitivity: ISO 400
Optimize Image: Vivid
White Balance: Shade
AF Mode: Manual

天空下著細雨，所以天空與地面的反差變小，直接對準天空測光，地面的景物還是清晰可見

Lens: 18-70mm F/3.5-4.5 G
Focal Length: 70mm
Exposure Mode: Aperture Priority
Metering Mode: Multi-Pattern
1/160 sec - F/5
Exposure Comp.: -0.7 EV
Sensitivity: ISO 200
Optimize Image: Vivid
White Balance: Shade
AF Mode: AF-S
