Pentax has a new digital SLR, known as the K7. The resolution is the same as the already excellent K20D, and it seems to have retained all of the cool features offered with the K20D (such as the weather-resistant design and the built-in interval timer), but they've added some very desirable new features, such as a movie mode and an optional vertical grip (very handy for portraits).
The interval timer would be very handy for self-portraits, upon which one could base paintings or drawings or digital art if one wished to do so; and it could do things a standard self timer couldn't do. (For example, I'd like to take a series of photos of myself while I'm playing an entire piece on the piano. A standard self timer would only take one shot, and then I'd have to get up from the piano bench and set up the camera to take another photo. That would pretty much negate the possibility of getting an authentic photo of a real performance.) The number of intervals (between 1 and 99 shots) and the length of time between shots (up to 24 hours, 0 minutes and 0 seconds) is more limited than the options offered by some computer software programs (such as software which comes with just about all Canon DSLR cameras) or by third party solutions such as the PClix LT or the much bulkier Mumford Time Machine), but having such features built into the camera would make it possible to take intervalometer photos in situations where one might be hindered from doing so with other solutions. (For instance, since the K7 is weather resistant, one could take intervalometer photos out in the rain. That would be much harder with other options.)
There's also a very desirable in-camera feature which merges three photos together in order to produce HDR JPEG files. For home editing, it would probably be better to create RAW files and then use a more sophisticated program to create one's HDR files, but the ability to make HDR JPEG files on the road without access to a computer would be very handy for making quick prints of exceptionally high quality at local stores equipped with photo kiosks, right after taking the photos. And since the K7 has a mode which shoots RAW and JPEG files togeter, there's no reason why one can't make such quickie HDR photos and also create better HDR versions later at home, even if the in-camera JPEG files can only be created from other JPEG files. But I'm guessing that one can create such files from RAW files as well, for higher quality.
