Highlight clipping

For this exercise I looked for an image that a wide range of brightness. The idea was to find an exposure setting at which the highlight clipping warning just appeared.




P503

P503: F8 @ 1/320  ISO200  84mm





P505: F7.1 @ 1/400 ISO 200  81mm     

P504: F9 @ 1/250  ISO 200  81mm



P506: F6.3 @ 1/500  ISO200  81mm

 

 



P507: F5.6 @ 1/1500  ISO 200  81mm





 

 

The next step was to compare the images side by side using Photoshop. For the exercise, I focused on the highlighted areas and to help the process of looking at the results, I magnified the areas.

 

Loss of visual information

 

This could be seen at the top of the head and shoulder of the statue in all images.

 

Visible break in the form of an edge between nearly white and total white.

 

There is a visible break  on the shoulder evident in images taken at P504( f9) - more than P503(f8), but less so in the image taken in P505 (f7.1), P506 (f6.3 )and no evidence in P 507 ( f5.6 ).

 

Colour cast along a fringe bordering the clipped white highlight.

 

There was a pink cast on the stone figure in images taken at f9 and f6.3. Also a bright green edge to the tree.

 

Colour saturation

 

Looking at the images, I could see increased saturation in P503 ( f8 ), P505 (F7.1 ) and P507 (f5.6).
