Hi Heather,
Hope you get the problems worked out with your digital camera, but since you're also considering getting a new one, I thought I would offer a few suggestions.
You may wish to consider getting a digicam with a
wide angle lens, particularly because you'll use it as a realtor. There are some fine digicams which have a 28 mm equivalent lens. A lens with a wide angle focal length is great for taking photos of the exterior and interior of homes.
We have a few examples here of the same shots taken at different focal lengths:
http://www.digicamhelp.com/what-is-a-normal-lens/index.htmDeb is right about the reason your shots have been coming out dark and blurry. When you back up to take a wide-angle shot of a room, for example, you may be shooting outside the range of the camera's built-in flash. Check your manual for the flash range at varying distances. Some digicams have a hot shoe, which let you add an external flash, though this may be more than you need.
Optical zoom - Your model camera only has an digital zoom which really doesn't do a good job of capturing clear images when used. So you should condsider a digital camera with an optical zoom if you have a need to zoom in to take shots. I have a digital zoom (as well as an optical zoom) on my camera and rarely use the digital zoom because the images look pixelated and therefore blurred.
Here's an explanation of the difference between an optical and digital zoom lens:
http://www.digicamhelp.com/digital-camera-features/digital-camera-lenses.htmCamera sensitivity (ISO) - I note that your current camera has only an ISO setting of 100. That's typical of most point and shoot digicams. However, many let you adjust the light sensitivity. Not everyone wants to fuss with these types of settings, but it's sure good to have them when you need them!
Here's some more info on ISO.
