Sigma dp0 Quattro

Examples: Cottonwood Canyon Area, White Mountains (Part 1)

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.

Images were shot in RAW+JPEG mode. Some are presented using the slightly tweaked JPEG files from the camera* and some of them are presented from X3F raw using Sigma Photo Pro. Examination of JPEGs from the Sigma dp0 Quattro cameras shows sharpness every bit as good as from X3F raw, which is consonant with the very large JPEG file size the camera produces.
