Hey, Norm's back from his K-3 vacation!
Iridient Developer is the only software known to man (other than Sigma Photo Pro) that can process Sigma's X3F files.
Here's something interesting I've been meaning to do for a while. In October, I took some pictures with the DP2M on a tour of the Four Peaks brewery in Tempe. Obviously, it was very dark in there, so, despite the dire risk to my health and well-being, I took some pictures at ISO 1600.
Here's one. It actually doesn't look horrible at websize. For all the pictures below, I turned off noise reduction and sharpening in SPP, and added +25 sharpening in Lightroom, a less heavy-handed replacement for SPP's default sharpening. No color correction or curve adjustments. I think it's been pointed out before that the colors start dying after ISO 400.
Here's a 100% crop of the same. On all the pictures below, clicking on them will take you to the full-size file.
The same, but processed in "Monochrome" mode in SPP:
Here's where things get interesting. This is just the red channel. As I've said before, red is on the bottom of the sensor. It gets the least light, so the camera has to boost it a lot to bring it up to the same level as the other channels.
Yikes...
And here's blue!
I've uploaded the raw of this file to the sample folder
here. It's the file called
DP2M, ISO 1600.
@NickLarsson , I see you dabble in B&W. IMO, if you take only the blue channel, the Foveon sensor is perfectly usable even at ISO 1600. Food for thought.
