Exercise 10:Colour cast and white balance. Part 2

For this part of the exercise I used an artificially lit Christmas decoration and placed it in the window of our house at dusk.
I set the ISO to 3200 and used an aperture of F2 with my prime lens.
These are the three shots:

Incandescent

Sunlight

Auto

Each version has different merits there appears to be very little difference between the Auto and the sunlight setting.  The incandescent version brings the sky out as blue and is perhaps the most striking and is probably my favourite of the three. 

Exercise 10:Colour cast and white balance.

For the first part of this assignment I had to read up on my camera settings as they are not as familiar to me as they could be.  Once I had reviewed them I found the assignment fairly straightforward.
The results are below: 

Auto

Cloudy

Sunlight

Shade

 It is noticeable on all the photographs that sunlight is the nearest to the Auto setting.  Also shade appears to bring the most change.

Exercise 9 Scene Dynamic Range

For this exercise I choose several different shots in different lighting conditions and used shutter speed for the indication of the dynamic range within each scene.  I set the camera to spot and used an Aperture of approx F4 for all the shots.

This shot was taken with a shutter speed of 1/400.  When spot metered the contrasting areas were: sky 1/200, far ground 1/125 and the darker near ground was 1/60.  This gave a scene dynamic range of 5 stops.

This shot was almost exactly the same taken with a shutter speed of 1/400.  When spot metered the contrasting areas were: sky 1/200, far ground 1/125 and the darker near ground was 1/40.  This gave a scene dynamic range of 6 stops.

Once again this shot was the same taken with a shutter speed of 1/400.  When spot metered the contrasting areas were: sky 1/200, tree 1/125 and the darker near ground was 1/40.  This gave a scene dynamic range of 6 stops.

 This was a much brighter scene but the auto setting still took the shot at 1/400 with f3.5 aperture setting.  When spot metered the brighter parts of the shot were 1/200 and the darkest 1/60.

 The final shot was an attempt at a reasonably flat shot even so the sky still came in at 1/200 and the foreground was  1/80.  The shot was taken at 1/400.

Overall despite the similar conditions the shots all came out with a similar dynamic range from a maximum of  1/400 down to a lowest of 1/40.  This indicates a dynamic range of 10 stops.  For most shots the scene dynamic range was more like 6-8 stops.
