Exercise 9: Scene dynamic range

Following on from determining the dynamic range of our camera we were asked to quantify the f stop readings and therefore the range of a number of additional images.

I did this by using the following method:

1. Set the camera to Av mode, using evaluating metering and took the initial image. 
2. Noted the shutter speed setting,
3. Reset the camera settings to manual setting and dialed in the Shutter speed as noted in step 2,
4. Change camera settings to spot metering,
5. Change to my longest lens (200mm)
6. Zoom into areas and take individual f stop readings throughout the image.

For the first image of Carnbooth Hotel in Carmunnock, whom I want to thank for allowing me to take some photographs, I used the following initial settings:

• Camera: Canon 5D MkII
• Lens: Canon 24/70mm f2.8L @ 24mm
• Mode: Aperture priority - f8 @ 1/200s
• ISO:  100

I recorded the individual f stop settings as show in the representation below.

For the second image of our house in East Kilbride, I used the following initial settings:

• Camera: Canon 5D MkII
• Lens: Canon 24/70mm f2.8L @ 24mm
• Mode: Aperture priority - f7.1 @ 1/40s
• ISO: 100

I recorded the individual f stop settings as show in the representation below.

For the last image of the garden I used the following initial settings:

• Camera: Canon 5D MkII
• Lens: Canon 100mm macro f2.8L
• Mode: Aperture priority - f8 @ 1/50s
• ISO: 100

 I recorded the individual f stop settings as show in the representation below.
