Yes it's worked John! Picasa may even give you an http link to enable you to show the image in the thread rather than having us go to the Picasa site to it. If they do, just highlight the link as you add it to your comment and click the image button below the 'Add a Comment' box.

Anyhow, that's a really nice twilight photo. That one certainly doesn't need any extra detail in the dark foreground. The picture is of that interesting dark red sky so detail in the foreground might even detract. There's nothing wrong with silhouettes!

As to whether highlight and shadow correction were turned on would make any difference, personally I doubt it would have made much of a difference either way. That function is mainly useful on sunny days (remember them?!) to help keep detail in the shadows and to stop highlights being burnt out. You don't need detail in the shadows here and the sky certainly isn't burnt out!

Personally I wouldn't want to make telephone calls on my K-5 any more than I want to take photos with my 'phone!

Perhaps the kind lady from Pentax could tell us?

All I can say is the camera manual states on page 202

RAW format is a CMOS sensor output format saved without
processing.
If Pentax don't tell us the whole story ...........

Not really. The camera takes the image as a RAW file and then processes it to a jpeg according to the settings. You can even reprocess the RAW file a second time within the camera with different settings, even if RAW wasn't selected! You can try this by pressing the down button after taking just a jpeg and you have the option to develop its RAW file providing the RAW image is still current in its memory.

The RAW file is just the digital equivalent of an image taken on slide or negative based purely on shutter speed, aperture and ISO - just like a film camera. It isn't processed at all. Most software packages, however, use the camera settings for reconstituting the image for further processing (or development.)

Most DSLRs take a 12 bit image. Newer ones including the K-5 take a 14 bit image. By combining images in suitable HDR software that can be extended further up to 48 bits.

There's no reason for HDR shots to look over the top. Without HDR my original jpeg file for the recent Buildings comp looked like this:

The 5 exposure HDR makes a world of difference:

Even with contrast AF enabled there is still some mechanical action going on between shots and I can feel a bit of vibration when hand held. Is that the aperture being stopped down?
Probably that and the shutter mechanism. Maybe using SDM lenses might be less violent? I'll try it later.

Put Pentax DL2 into Google Images and see what comes up.

I'll do it for you: Pentax DL2

Remember though, just because the images can be viewed freely doesn't mean they can be reused elsewhere without permission from the copyright holder. Personal use would surely be fine though.

What is that software then John. I for one would be interested

For Windows 9X, NT, XP:

or using Windows Movie Maker - tutorial:

MakeAVI

When taking the photos, it would make sense not to set everything up at the highest resolution. Better to start low and work up!

For the record I haven't tried any of the above software for this purpose. I think for starters I'd go for MakeAVI. It's open source software and has a 96% user rating and looks simple to use!

I've found a workaround. Put the camera in Liveview mode before taking the sequence which of course causes the mirror to be flipped up throughout. The picture can still be framed in the viewfinder first if lighting conditions make viewing the screen impossible.
