Take a look at other makes as well. I have used many different models and makes over the years, my Nikon 4300 has performed extremely well with over 10,000 shots taken so far. I used the Kodaks several years ago and was not impressed, hopefully they are better now.
If you want a really informative site go to
www.dpreview.com, they provide indepth reviews with photographs.
On to your questions:
- Models vary based on how many megapixels they have, response time, format (rangefinder or SLR), optics, etc.
- Cards are much less expensive now, a 512mb storage card can hold around 500 photographs at fine resolution for a 4 megapixel camera. Unless you plan to take more than that I would skip the laptop, at Disney I always vow to take a lot of pictures but never go over 250.
- I did a small commercial job using my Nikon 4300. I took around 150 photographs in one hour, and had the job done so quickly that my client could not believe it. The quality was very high as well. Megapixels are important but so are the optics of the camera lens. The camera used by NASA on Mars was only 1 megapixel but had such state of the art optics and CCD circuitry that the pictures were sharper than conventional cameras at 8 megapixels.
- If you dump (download) your pictures to a laptop you can erase them from your card. The card is like a portable mini hard drive and will show up on your computer as one with folders. You can use the card over and over, no limit.
I strongly suggest you try out a few models to see what you like as well. LCD preview screens of your shots are good to have but don't show the picture quality clearly enough, only when you see it enlarged on screen can you make a good evaluation.
PS: I just bought a Canon I960 printer. Simply amazing! I loaded 20 sheets of 4x6 photo paper, picked 20 images to print and out came the prints in about 10 minutes. Friends and family can't tell the difference between them and professional lab results...
PPS: Please keep multiple digital copies of your photographs, there are many horror stories of computer crashes, scratched discs etc. where people lost their entire portfolio. Although prints are rated between 25-100+ years (normal analog prints from film cameras fade after about 25 years) this is based on optimal conditions. I keep my digital photographs on my computer hard drive, a CD-ROM and a backup CD-ROM which I store offsite.
