Dr. Munhi,

I feel that you have grossly under-appreciated the extraordinary technical wizardry involved in the capture and post-processing of my image! (Well, it involved lying down on the living room floor and taking the pic. In post processing it needed a white balance adjustment, contrast adjustment etc.)

Just thought I mention it
Ahhh, yes, one more thing: I forgive you

More seriously: Great judging and a deserving winner. It certainly would have been one of my contenders.

Now I better get back to B&W conversions in anticipation...

Dr. Prieni

K20D, Sigma 70-300/4-5.6 APO DG, 8 s, A11, ISO200.

Just to show you that it's not all bad with the new K20D (see this thread), here is a sunset shot with the 10-17 mm fisheye:


K20D, 10-17 mm @10mm, A13, 1/8 s, ISO200 (DR 200%)

Yes, that's how it looks in SilkyPix as well as on the camera display. The uploaded shot is processed into a TIF file using SilkyPix, then resized and converted to JPG in Photoshop.

Nope, there was plenty of space left on the card.
I put the same original post up on depressing review as well and had one reply telling that they had a very similar thing happening once (from >1000 shots so far).

So I guess that another candidate for cause could be a software glitch that occurs under certain circumstances only (that's a programmers favourite, some error that you cannot reproduce but that appears from time to time...)

Thanks for your suggestions.

Martin:
It could be, of course, a problem of the card. Haven't had much experience with it (about 130 shots so far). It is new (the *istD takes CF cards) and I always format in the camera after downloading pics to the computer.

Chirpy:
Yes, I also find it a bit too regular (and this on two different scales, the bar and the line pattern). Yes, I had my mobile in my pocket, not too far from the camera, all the time. So we cannot rule out interference from that.

Have to check about the SR. As far as I remember I had switched it off. Shouldn't make a difference, though, as I used the 2 s delay which should switch off SR anyway.

Mongoose:
Not so classic as I took it as a RAW (PEF) file...

So, two candidates so far: SD card and/or interference.

As I said, I will keep an eye on it. If I find more hints I will let you know...

Finally I found a bit of time to give my new K20D a bit of a test run. Works like a treat. So I shot the sunset and a few more pics after the sun was gone. The last one in the series turned out rather strange:



100% crop:



I have no idea where the bar on the left comes from nor do I have a clue why there is the "banding" in the picture (everything left of the "bar", you can see it in the 100% crop if you get a bit closer to your screen).

I left the EXIF data on the bigger one. The same exposure (2 s, A11, ISO 200, DR increase) was used on two previous shots without these artefacts. I do remember, though, that I had to tighten the quick release plate to the camera as it was turning when put in the vertical. However, after I noticed the artefacts I took some shots at home without loosening the plate and pictures were fine.

Any ideas as to the reason of this?

I am not overly concerned at the moment, but certainly will keep an eye on it...

Prieni

I agree, much better leading line in portrait...

Now you spoilt it for her, she didn't notice on her b&w monitor....

Congratulations to Dr. Munhi from Dr. Prieni !

And well done George for a swift and well balanced judgement!

Some very nice entries again!
