Perhaps pushing the boundaries of astrophotography a bit, but I would point you to the correctly exposed stars in the night sky. The land is lit by moonlight.

A photo from last Fall's trip to Paris. I'm atop Notre Dame, looking out over Paris. There's no filter on the lens, but this may have been post-processed with a funky color curve.

Camera: my doughty Pentax K-x in white, highly recommended because people think it's cute, not pro.
Lens: DA-L 18-55, in matching white, somewhat like this, but no weather sealing, metal mount, or quick-shift manual focusing.

K100DS vertical line on sensor?

Thanks for the suggestions. To answer some questions:

-I haven't checked properly (lay two images over each other in Pixelmator), but I'm almost certain it's in the same place on every pic. I'll confirm that asap.

-Good suggestion about cloning the row! That's a definite way to rescue some of my shots.

-Almost all of my shots are RAW. I usually just use iPhoto, but I previously cranked a few shots through Pentax's developer or some other. Same, though it might do better with the low-ISO shots.

-It is in every shot, but far less visible in low-ISO stuff. Presumably the system is able to compensate better. Is this normal for hot pixels?

-I'll cross-check with another card, but yes, looks like a sensor failure. Oh well, time to start saving for a K-x! I wanted movie mode anyways :).

K100DS vertical line on sensor?

So somewhere around the end of September last year, I started seeing a vertical-line artifact in photos on my K100D Super. Here's a crop:

Attachment 60597

(I've rotated this).

-It's definitely much more visible at high ISO. At 800 ISO it's much harder to find. I can just find examples of it in my ISO 200 images if I really try. This, however, is an example at 3200, where it's a pretty distinct blue-tinted line.

-it's pretty much centred on the sensor, and extends up about 2/3 of the sensor. I haven't measured it precisely.

-Firmware is 1.00. That's the one and only for a D Super, right?

Anyone experienced this? What are the likely cures? What was the likely cause? Is this pretty much a "send it to Pentax" problem?

Otherwise, the camera is working just fine.
