Just got an external isight-

Question

Been trying it out and I was wondering if the image quality is better than the more recent built in cameras on the mac. Its certainly better than the USB cameras that my buddies have.
If I could only figure out version I have....

Hello Zband
... if the image quality is better than ... built in cameras on the mac.
Given normal webcam distance from the lens and adequate light (video takes more light that normal room lighting), I think the image quality is approximately equal.
External iSight has auto-focus so it can offer better images at widely different distances to the subject. It is also easier to attach filters and accessory lenses, but this difference is not really an image quality difference.
If your only use for iSight is video chat, your image quality question can best be answered by your video chat partner, who is the one who sees the image your iSight sends. Here is a comparison video test I made some time back with a chat partner who has both internal and external iSights.
My chat buddy changed NOTHING between the two pictures except which iSight he was using. I see differences in the amount of software image sharpening, contrast, and color balance. However, I do not see any significant difference in image quality between the two.
If you want to compare the quality of snapshot still images for email or posting on the web, the best way to critically examine image quality is to make a print of the same subject made with both cameras. I have not done this kind of test using my iSight because, although I occasionally make an iSight snapshot to email, I almost always use my digital still cameras for images I want to have enough quality to print or post.
Rather than accept my assessment, you can do a comparison and judge for yourself. Capture an image of your face with both your iSight and a different Mac that has a built-in iSight. It is best if you do this as near as possible to the same time, same size, and in the same light. Then print both images and look for image quality differences that are important to you.
If I could only figure out version I have....
Look on your iSight's Packaging. The version/model number is printed on the outside of the box near the serial number.
If you did not get the original packaging with your iSight, look in System Profiler. (System Profiler's model identifier is different from the model number printed on iSight's packaging.) To find your "Model:" information, your iSight must be connected. Launch System Profiler, and click the items shown below to see the info about your iSight:
Your Service Tech can find out, too, but he only needs iSight version information in case he needs parts. However, from a user point of view, all external iSights work alike.
My old Rev A works just as well as exactly like the last ones made. The only iSight model ("version") difference important to users is which mounting hardware was furnished. My Rev A came with adhesive mounts, while Rev B and C came with Magnetic mounts for the aluminum framed Apple Displays. All versions had a reasonably good mount for your PowerBook.
