DPP: Exercise 6: Highlight Clipping

The purpose of this exercise is to demonstrate the process of highlight clipping.  This happens when at least part of an image is overexposed to such an extent that visual details are lost in what appears to be a bright light, or bright spot.  It may also be said of such an image that it is "blown out," that is detail is blown away by bright light.

The brief calls for finding the exposure settings at which highlight clipping first appears in a contrasty scene (some light and dark elements), then shooting one image one-step higher, followed by three images each one step lower than the preceding.

Simple as it seems, I am having some difficulty.  What my Sony RX100 and Lightroom tell me are not the same.

This is a rather poor capture from my iPad, but it serves the purpose as it shows the camera reading a large area of highlight clipping on the left near a window.  This flashes black in camera.  Note that the histograms show minimal clipping in blue.  Also note that this is not a live view available while shooting, but viewable only after capture.

DPP: Exercise 5: Linear Capture

The purpose of this exercise is to demonstrate the interpretive ability of the camera’s software by looking at what the sensor captures and comparing it to what software renders.

To do this we are asked to take any JPEG or TIFF and first convert it to 16 bits per channel using Photoshop.  I did a bit of googling to find out how to do this in Lightroom before posting to the OCA Photography forum for clarification.  It turns out LR processes in 16 bit and exports JPEG at 8-bit.  JPEG bit depth cannot be adjusted (so far as I can tell), but TIFF can be set at 8 or 16.  So for the purpose of this exercise I exported a 16-bit TIFF.  This is the image, a souvenir collection from a student who went to Mecca for Hajj.
