I would like to know about the ins and outs of digital cameras. Often I need to take pictures on various construction sites for insurance purposes, ect..... as a visual record and I am forever tired of taking my old Kodak film in to get it developed! If what I have heard is correct, I should be able to store all images taken by a digital camera into my computer and print them anytime I need. What kind of software/hardware do I need? What are good brands (cameras & software) to choose from? What about cost?
