There are a lot of different options out there. Are you reasonably computer savvy ? If you're reasonable tech savvy, then you should be comfortable with a digital camera.
Which to buy ? You're going to need to do your homework. The thing I like about Amazon is that people leave reviews of different products. Whenever I am in the market for a new camera, I check out the different popular models to see which suits my needs. Because the days of the point and shoot are over. These days, cameras like cell phones are multifunctional.
Also, how much are you willing to pay ? A decent low end digital camera will cost around $100. But, depending on what bells and whistles you want (example a good lens) will cost more. The more bells and whistles you want, the higher the cost.
Speaking as something of an amateur photographer, the MOST important component of the camera is the lens. Because if you have a crappy lens, you're going to get crappy photos regardless of how good the hardware is. the two best lens manufacturers in photography are Carl Zeiss and Leica.
You don't have to buy those cameras to get those lens. The Panasonic Lumix cameras use a Leica lens. The Sony Cyber Shot cameras use the Zeiss. Both of those cameras are excellent, but pricey i.e. over $200. Once again, a good lens will cost you, but it's an important investment if you want good quality photos.
Kodak does make a good digital camera that isn't too costly i.e the Kodak Easyshare. So, if you are looking for something around $100, I'd go with a Kodak. However, if you're willing to pay the $$$s, I'd go with a Panasonic Lumix or Sony Cyber Shot. Of course, Canon and Nikon also make excellent cameras too.
See, another consideration to take into account is how the camera fits in your hand. Just because we recommend buying a Panasonic or a Nikon, you might not like the feel of the camera in your hand. So, one thing to do is go to a place like Bestbuy or Staples to try out some of the different model cameras.
I do use an older model Lumix, it's two years old. LOL !! I like the way it felt in my hands because it had some weight to it. I liked the lens quality. I liked the width of the LCD screen. Some digital cameras have small screens. You might not like that. I know I didn't.
People rave about the quality of the photos I've taken with the Lumix. I have a few posted in my washington DC trip blog if you'd like to see some examples.
My advice is to check out different models at the store. See what suits your needs and your budget. www.sparkpeople.com/mypage_public_journal_
