Presented at full resolution (5424 width is full resolution). Some images offer a color/B&W toggle. The images have been re-saved to reduce file size somewhat, but the quality is very high; no discernible loss of sharpness occurs due to the re-saving. Date and times for images are inconsistent; the camera screwed up the date and time via some kind of glitch. Some of the dates were fixed, but I missed doing so with some of the images.

Sigma dp Quattro cameras utilize an APS-C sensor. Versus a 35mm full-frame sensor, f/4 has the depth of field of f/5.6, and thus f/10 is equivalent to f/14.
