Exercise 4.5 - Light through the day

In this exercise I had to take several pictures of the same spot through the day. The aim was to see, how the lighting in sunny day changes through the whole day and how different the subject and the background looks at a given point in time.
All shots were taken at 42-46mm focal distance. I also tried to keep aperture at f/20, where possible. ISO was set at 200 for all pictures.
The pictures were taken on the eastern coast of Corfu island. As it was eastern coast, the number of shots in the morning is a bit more than in the evening.  

Time: 5.30 a.m

42mm; f/16; 3.0 sec 

The colors are bright in the dusk and the sky is showing clearly three colors changing one another - from orange to light blue. Only contour of the mountain is seen on this shot.

Time: 6.00 a.m

42mm; f/20; 1/15 sec

Compared to the previous shot, there was more light, and colors became less saturated. Also, the shutter speed is not that long. Within half an hour it has changed from 3 seconds to 1/15 sec. The contour of the mountain is now dark grey as opposed to black on the previous shot.  

Time: 6.30 a.m

78mm; f/20; 1/30 sec

Here I changed the angle of shooting a bit, though it was according to the exercise. But everything is possible for the sake of good shot. I have also use a gradual ND filter here P21. Otherwise, the sun would be extremely bright and would lit the whole picture. So, I am not quite sure if this shot can be counted as part of the exercise.

Time: 8.30 a.m:

46mm; f/20; 1/500 

As sun was high enough at this time of the day, the colors of the on the shot have changed dramatically and made everything light blue. Though, as it was not too high yet, the shadows and different contours of mountains are seen much clearer than on the previous pictures. The shutter speed was shorter than on all previous shots.

Time: 10.00 a.m:

46mm; f/20; 1/80

The colors look more saturated here, and more patterns of the mountains can be recognized on the shot. the shot has been take from the shadow. I think it has also influence the level of colors saturation.

Time: 12.00 a.m

46mm; f/20; 1/60 sec

This shot has been taken at midday, and with at this time I decided to use polarizing filter to diffuse some of the light, as there was more then enough sun. The colors of the sea have changed during the last couple of hours. And some clouds appeared on the sky. It can be seen how the color of the sea has changed from the light blue to different lines of blue color and a green tone appeared.

Time: 14.00 p.m

46mm; f/20; 1/40

The difference between 12.00 and 14.00 is not that obvious. Though, because the sun is a bit lower and there are more clouds on the sky, the mountains and the pattern of the trees is more obvious. This shot has also been taken with polarizing filter. 

Time: 16.00 p.m 

46mm; f/20; 1/125 sec 

This shot has been taken without polarizing filter, which allowed faster shutter speed. Though, the saturation of the colors is less. 

Time 18.00 p.m : 
42mm; f/11; 1/125

At 18.00 a.m the colors became more like in the morning, turning from saturated blue and green into the light blue. The mountain itself is now a bit in the mist. The color of clouds has also changed into light grey. To be able to shoot from hands I had to change the aperture to f/11.

Time: 20.30 p.m

46mm; f/20; 2,5 sec

The whole picture is completely blue here, very similar to the morning one taken at 08.30 a.m. what makes the difference is the shutter speed. In the morning it was 1/500 sec, and in the evening it is 2,5 sec. 
That's why the sea surface looks different on these two pictures. 

This shot was actually the last one that I managed to take that day. It was completely dark outside, when I came back one hour later. 

As these ten shots are showing, the amount of light and the time of the day when the pictures are taken is  one of the main factors influencing the picture. The number of colors, the colors saturation and the temperature are different at different points in time during the day.
