Objects with blue sky background

When shooting outdoors, sometimes we are tempted to take pictures of people / objects with blue sky background (bright). Usually these conditions can be obtained during the day (over 10 hours). However, usually the desired results are not as expected, for example, objects in the image into a silhouette or the background to white sky (over).
 

This happens because we are fooled by lightmeter difficult lighting conditions, the background is too bright (bright blue sky) while the object is darker than the sky background. So when we do the metering into the sky had become the object silhouette, whereas when we do the metering to the object, the sky becomes white.


These conditions can be overcome by the use of flash. The goal is that the object and background clearly visible (not over or silhouette). Here are the steps shooting:


1. Set the angle and composition of the photograph to be made.

2. Use the manual mode on the camera.

3. Turn the lights flash

4. Shuter Arrange a safe speed to keep the camera steady (not shake), I usually set the speed Shuter, 1/ISO or 1/focal length lens.

5. Perform metering into the sky, and set the camera aperture so that the indicator lightmeter exprosure show that under (can be ½, 1, or even two stops), usually by way of discouraging the aperture, then adjust the focus.

6. Finally, push your camera Shuter.

     Above techniques sometimes bring up an error which is an object photographed a little over. This can be solved by shrinking the camera aperture and reduce the intensity of the lights flash. Shooting distance to the object is also worth noting in this technique. If using the internal flash (GN 12-15), then the shooting distance between the camera and the object should not be too far away (1-2 feet), whereas if you use external flash with a GN larger, it can shoot farther distances.
