Phase One IQ4 + Schneider Kreuznach LS 150mm f/2.8 Aperture Series: MemChu

I was curious whether the Phase One IQ4 frame averaging feature could be used outdoors in order to achieve exceptional dynamic range.

In particular, I wanted to capture an intense glare off an icy lake while also retaining outstanding detail in the deeply-shadowed mountainside, a challenge that in my experience over decades no camera has ever met before to my satisfaction.

Well, this example shows why pros who want the best shoot Phase One.

In diglloyd Medium Format:

Phase One IQ4 Image Quality: Extreme Dynamic Range in the Field (Lundy Lake)

Includes images up to full 150MP camera resolution in both color and black and white.

NOTE: my output script developed a bug (a change I made), and this image is too dark because a key adjustment layer was omitted. I need to fix that bug and redo the image.
