By Dave Etchells Finding the Right Digital Camera The overall goal of the Imaging Resource website (www.imaging-resource.com) is to help people chose and use digital imaging technology as effectively as possible. As simple as they are to use, choosing the right digital camera involves a number of decisions. Key issues are computing platform, image quality, onboard image capacity, exposure versatility, feature set, and included software. In this article, we'll lead you step-by-step through some of the issues to consider in making a purchase decision, and at the same time, suggest some things to look for in the test images we've collected on our website. We're interested in your feedback and experience! We invite you to elaborate on this article by leaving comments via the database link at the bottom of the page. You can also give feedback in our "Forum" discussion-group section. Computing Platform This is an obvious consideration but it is fast becoming less of an issue than it o ...
