Exercise 4.4 - Variety with low sun

The aim of this exercise was to take some pictures at sunset and see, what the difference in lighting was. The object should be placed at a different position in relation to the sun.

For all four pictures white balance was set for Sunny and ISO for 800.

1. Frontal lighting - with the sun behind the camera. As can be seen on this picture, there is enough depth of field, the shadows and shapes can be recognized. None of the sides of the shots is under- or overexposed.

46mm; f/4.8; 1/1250sec

2. Side lighting - with the sun to the left or right. In this case, sun was shining from the right side. There are less shadows and the right side of the object seems to be a bit overexposed. Though, this kind of lighting can be used in interesting ways, when taking pictures of people faces, as one side of the face would be in light and the other in shadow.

55mm; f/5.0; 1/800 sec

3. Back lighting - shooting towards the light. The first thing you notice, when shooting against the sun is that shutter speed increases nearly twice. The other thing is that, by having sun correctly exposed, the object itself is underexposed. To have both, sun and object, exposed in a correct way Cokin gradual ND filters can be used. I personally often use P 120 and P 121.

50mm; f/4.8; 1/3200 sec

4. Edge lighting - sun is just outside the viewfinder frame. This way of shoots has resulted in upper left corner being overexposed. This could also be corrected by using ND gradual filters. The object itself is mostly in shade.
50mm; f/4.8; 1/640 sec

Summarizing this exercise, it can be concluded that different angles of sunset can be used for different types of shots, depending on what you want to achieve. Side and edge could be probably used for portraits to catch interesting angle and a shade. Shooting against the sun requires some filters, but helps to take really nice sunset pictures.

Exercise 4.2 - Judging Color Temperature 2

The same as with the previous exercise, there will be two shots of my father's face and one sea shell. But in this exercise, I should look at different white balance settings and how they affect the temperature of the colors.

1. At Sun - these three pictures have been taken at sun during the midday:

The first one has been taken with white balance  set for Direct Sunlight.
145mm; ISO 200; F/6.0; 1/800

The second one has been take with white balance set as Auto. 

130mm; ISO 200; f/6.0; 1/800 sec

The third picture has been take with white balance set at Shade.

150mm; ISO 200; f/6.3; 1/800 sec

The color temperature is different on all three pictures. Th interesting thing is that I would expect Shade white balance give cold temperature, while it appears absolutely the other way around. the coldest is Auto, and Direct sunlight is something in the middle. 

2. At Shade - these three pictures have been taken in shade during the midday.

On the first picture white balance was set on Direct sunlight.

170mm; ISO 200; f/6.3; 1/100 sec

The second picture is taken with white balance at Shade setting.

145mm; ISO 200; f/6.0; 1/100 sec

The third one is with white balance at Auto.

185mm; ISO 200 f/6.3; 1/80 sec

White balance set for shade gives the warmest color temperature. Again is the coldest one.

3. These three pictures have been take at sunset.

The first one has been take with Shade white balance 

90mm; ISO 400; f/4.5; 1/100 sec 

 The second one has been take with Direct sunlight white balance

90mm; ISO 400; f/4.5; 1/100 sec

And the third one has been taken at Auto white balance

90mm; ISO 400; f/4.5; 1/100 sec

In this case Shade has given the warmest color temperature. But as opposed to all previous pictures, the coldest one was given by Direct sunlight.

Summarizing this exercise, I can say that  Auto balance would usually give the shot colder temperature of colors, except for sunset case. The balance can be reached by applying the white balance that is relevant for every particular case. 

Exercise 4.3 - Judging Color Temperature 1

Unfortunately I could not use the same object for all three pictures. I failed to make a picture of my father at sunset. So, I have chosen another object that is also not very colorful and will show the same difference in color temperature - a sea shell.

For all three pictures white balance has been set for "direct sunlight"

1. This picture has been taken at the sun in the midday. The tones are moderate. Color temperature is exactly what it should be, not too "warm" or too "cold". The shadows are not making the picture too dark.

145mm; ISO 200; f/6.0; 1/800 sec

2. This picture has been taken in the shadow during the midday. The colors look colder than on the previous picture. And because the face is not in the sun rays, there are no shadows at all. 

170mm; ISO 200; f/6.3; 1/100 sec

 3. At this one, colors look the coldest out of three. I would even say that the background has blue tone, whereas it was not blue at all.

90mm; ISO 400; f/4.5; 1/100 sec

The most natural is the first picture, where at white balance set for direct sunlight, the shot is actually made at direct sunlight. Two others have colder temperature and the tones of colors differ.
