How can you tell if a website is collecting info about you?

Q. I got an email from my isp saying I violated some kind of copyright law. That got me wondering. Is there anyway to know whether a site I visit collects my ip address or any other kind of identifying information?

Lets say I go to a site on camcorders, can the site collect my info and then sell it to marketing people? Can I expect to get regular mail from Sony, Canon, and others on their new products?

A. There is not really a way to see if sites are collecting your information as it happens, but the best you can do is try to prevent it from happening in the first place. Normally you have to consent to things like that in some way. Look for the fine print on any web page you visit. If it says they can and/or will sell or give your information to a third party, leave the site. Most sites, however, will have a box that you check that will say something to the effect of "Yes! I would like to receive notices from Canon and its affiliates regarding new products and special offers in my e-mail!" and another one that says "I do not wish to receive e-mails from Canon and its affiliates." In that situation, you would obviously click "No" because clicking "Yes" would allow Canon to share your information with it's "affiliates." Disabling cookies in your browser will help as well.


What about camcorders having 70x zoom if any, with both excellent still and motion megapixels?
Q. I heard about a Panasonic camcorder having 70x zoom but 0.8/0.9 megapixels for still image with less resolution. What does this mean ? Is there any Sony or Canon product having both excellent zoom more than 50x(say) optical zoom with 12 or 14 megapixels - still imaging, with high resolution ?

A. To get high resolution still images and high zoom, you would need to use a D-SLR combo camera with whatever lens you desire (.mm). Combo D-SLR's record video in HD but have much larger sensors than typical consumer-grade camcorders/cameras. If the zoom factor is very important to you on a camcorder, make sure you consider Optical zoom not Digital zoom. Optical is true lens zoom and digital is basically magnifications of the pixels, thus fake and looks terrible when used. Most consumer-grade camcorders can take still images at around 5 or more mega-pixels which is fine and high zoom requires the use a tripod for sure as a tiny bit of movement (nervous hand, wind, etc.) of the cam and/or tripod will be acerbated in the final video (looking shaky and unappealing to the viewer).
