High Dynamic Range
Sony A7S‘s high dynamic range doesn’t mean images shot on it appear flat – it just means you have lots shadow and highlight detail that can be recovered if you need it.

HDR photographers are going to love the A7S dynamic range! This is a 32-bit HDR image created from a four shot bracket then edited in Photoshop HDR Pro.

Here’s another 32-bit HDR image created from 3-shot +/-2-stop bracket edited in Photoshop HDR Pro.

Imagine being able to capture HDR in a single RAW capture. With the A7S it’s not that far-fetched.
Here’s the -2 stop exposure with the shadows opened and clarity added in Lightroom 5.5:

In low light, Sony A7S’s dynamic range even exceeds the impressive dynamic range of Sony A7 and A7R.
Images of the same scene in Rio de Janeiro shot on Sony A7R and A7S were processed in Adobe Lightroom 5.5 (Amazon | B&H) and adjusted for maximum dynamic range. Highlights were pulled down to -100 and Shadows were opened up +100
I know these look flat at this point – just bear with me…

With mid-tones equal, the A7S image appears to hold an extra 1/2 stop of detail in both highlights and shadows – resulting in more shadow detail in the leaves of the trees without clipping highlights on the beach where the sand and water meet.

Since the images adjusted for maximum dynamic range appear flatter than I like, I’d add contrast, midtone clarity and a bit of vibrance (saturation) to put the snap back.

This means you can confidently shoot away knowing the final images will match you vision.
