More on highlights: my learning from the exercise 2 on 'highlight clipping'

Image 5
This image was exposed for 1/60s at f/11.
The highlight clipping is appearing across a much wider area of the sky. 
Analysis of the magnified image shows that:
There are some areas that display a complete loss of visual detail.
It’s possible to see a clear break in the edge between nearly-white and total white.
A colour cast is noticeable in the areas around the clipped white highlight, particularly slightly below the area displayed in the magnifications.
The colour saturation is affected mostly in the areas immediately adjacent to the affected parts of the image.


Images 6 and 7
Image 6 was exposed for 1/30s and image 7 for 1/15s at f/11.
The highlight clipping is progressively taking over the whole are of the sky and is spreading down to the river. All reflective areas (such as the river and shiny metal details of the bridge) are affected.


Image 7 displays a complete loss of highlight detail. The colour saturation of the whole image is affected with all the colours, even those in shadow areas, appearing dull. There is a really unpleasant colour cast appearing in the areas bordering with the clipped highlights. There is a clear and visible break between nearly-white and total white.
