1) What to Buy?
With so much to choose from, and so many "parameters," it's hard to buy your first digital! I could do a who month of "freebies" on this alone, so I'm going to make it easy and short... If you need more detail, feel free to e-mail me.
2 Basic kinds - the ones that save the pictures on floppies, and the ones that same pictures on little cards.
If you want the camera primarily for working with buyers and/or just shoot one or two shots at a time, etc - I would recommend the SONY MAVICA. This type uses a regular floppy disk to store the pictures. They make several models ranging in price. Get the cheapest one if you don't do lots of fancy flyers and web stuff. Get the middle one for best all-around quality and features. The expensive one has sound and many higher-level features - get this one only if that is appealing to you. The Mavica is good quality, easy to use, but is bigger and heavier than most because of the floppy drive.
If you do more shooting, take the camera on personal vacations, use a laptop, and do more listing-oriented brochures - then I recommend the "card-type" cameras. The Kodak DC210+ is a solid performer with a perfect set of features for good Real Estate shooting and since it's "last year's model" it is very affordable - around $350 on-line. The next step up from there would be to get more features and pixels - The Kodak DC260 and 265 have sound and mini-movie capabilities (but not too much more "camera" than the 210+) Much more $. My own camera is the Nikon Coolpix 900S - I bought this model for it's supurb optics and more professional manual-operation features, but it costs about the same as the more expensive Kodaks!
Either way, get a camera with a ZOOM lens. It's more important to get the widest angle instead of the longest telephoto. Again, the 210+ has one of the wider zooms.

First, charge the batteries and install the software and cable.
Settings on all the cameras vary, but most have some common basic features. here are some tips:
3) Shoot!
The best part about digital cameras is that you can shoot like crazy and not cost any money! So do it! You get better every time you push the button.
There is one little trick to learn as you shoot with digitals. First, it takes a little while for the camera to "boot up" - keep the camera "on" during your shooting session if you want to be able to get quick shots. Second, there is a slight split second delay from when you push the button, and the picture actually is recorded. Most cameras have a shutter button that you can push "halfway" to activate the autofocus, autoexposure, and autoflash - but not shoot. It is good to learn how to do this for better shooting. You only learn this from practice, and then it's like riding a bike!....
Outside, in the sunshine, the little LCD screen is worthless even on the best cameras. Learn to use the regular optical viewfinder more for outdoor shooting. Besides, the screen uses alot of power, the more you use the viewfinder, the less you have to use the screen.
