How to shoot more blue sky

After a period of rainy weather, the last few days to see a rare blue sky, I believe we go out to the interest in shooting has improved. But we have not found, even though the same shot in the blue sky, blue sky, the degree of difficulty will be somewhat different. How can what the sky looks more blue it?jvc gr-dv500u charger

Seasonal factors

Even in the same place, taken the same direction, making out in the summer and winter, the blue sky is different. In the winter, making it the sky is light blue. During the summer, shot out of the sky will be dark blue. In general, from June to August each year is relatively easy to shoot the deep blue sky.jvc gr-d270u charger

The direction of the sun

Long days of clear air even in the days of shooting, more or less air there is little Xia gas. Xia, the impact of gas on the blue sky, the sun's position in the vicinity of the most obvious, very often turn white one. Only when the air is very clean place, the sky near the sun will be the same blue. Therefore, even if there is blue sky, blue sky is not the average, the most blue light near the Sun, and the sun direction at 90 degrees to the most dark sky location. We only make a gun shaped gesture, a finger pointing to the sun direction, the direction of thumb is that you can turn the blue sky where the deepest.jvc gr-d270 charger

Post-processing

Using PHOTOSHOP software like the blue sky deepening easily, although a little irrelevant, but it is easy to use way, and here must be mentioned. Open the file, select the menu Image (Image) -> Adjustments (Adjustment -> Replace Color (replace color), will point to the sky blue dropper place, Preview will show the selected areas (white location) We can adjust the Fuzziness (color tolerance) to adjust the selected range. and then simply Replacement (replace) column of Saturation (saturation) increase, Lightness (brightness) to reduce to the blue sky can be enhanced. However adjustment range should not be too large, otherwise the blue sky gradient will be affected.

Use filters

There are two filters can enhance the blue sky, respectively, and the graduated filter is a polarizer. Polarizer is the most common use for the saturation of the blue sky to strengthen, making clouds more apparent. Shooting, as long as the slowly rotating polarizer in front of the lens from the viewfinder or LCD carefully watched the sky color changes. When the sky turns blue when the deepest, it means a polarizer has been adjusted for the best angle to take pictures. But we know that when the zoom or focus group before the mirror rotation will change the angle of polarizer.jvc gr-d244us charger
