Aim: This exercise is in two parts. Part one is a series of shots that are deliberately lighter or darker than average with a description why. Part two is series of 5 shots but for each shot there are 5 exposures based around the average to see whether lighter or darker exposures are more accurate or provide a better image.
Approach and results:
Part 1: The first thing to note here is that the shots that are deliberately dark have small but bright points of interest that do not look good shrunk for the blog. The following three images are all darker than usual because I wanted the particular bright areas to be the interest in the picture. In the first picture it was the shaft of light round the end of the arch and the sunlit leaves that caught my eye. I took a series of pictures to get to this result. The first picture gave an even exposure bringing all the detail out in the foreground and walls but blowing out the sunlit areas. At this point I set the camera to manual, set the aperture I wanted for the depth of field and then altered the shutter speed until I got the result I wanted.
For the shot of the church window I took a spot reading from the window as the average exposure lost all detail in the stained glass (which was the reason for the picture). I then set the exposure in the same way as I did for the first picture. I approached the shot of the stairs in the same way.
|F7.1 1/125sec ISO200|
|F7.1 1/100sec ISO200|
|F5.6 1/200sec ISO200|
For the second shot of the vine I took a spot reading off the grapes as the first exposure made them too dark with very little detail. The background is now bright but surprisingly acceptable as it is not the focus of the picture.
|F8 1/30sec ISO200|
|F4.5 1/160sec ISO200|
