Promises a lot and delivers headache
2008-09-06I bought MacBook Pro from Newegg and it came with obsolete operating system and without support. It took three days to resolve support problem and update operating system. IMovie crashes repeatedly. The worst thing is that when it does you have to wait up to an hour for the system to go through its paces to do anything else. Generally there are delays in any application and one never k nows if the system got stuck or it is doing something. Most of the time there is no indication what the system is doing. I do not think I will ever buy another Mac again.

Great!
2008-09-05I used to be a Macbook 13" but I'm a Macbook Pro now. There's a huge difference in performance and hardware. Specially because I'm running with 4gb RAM. Congratulations to Amazon: 1day for delivery time and the on-line Rebate.

Piece of garbage!!
2008-09-05What's nice is paying $2,000 for a new computer, only to have the hard drive fail after 6 months. Garbage, garbage, garbage! Save you money and buy a PC, which is what I had to do when my computer's hard drive failed 2 days before I started school. Wish I could have my money back on this lemon.

Should have switched a long time ago
2008-09-03Mac is the Cadillac of computers. It looks good and works just as good as it looks. Very fast, amazing display, user friendly and lots of extras built in. Now that I am able to run Windows and Mac on the same machine, I find I am using Windows less and less.

Good laptop but poor quality.
2008-09-02I have this notebook for little more than a month, but it went back to Apple two time already. First time is the delete key fall out, and now the hard drive is disappeared in the system, meaning the system can't locate the hard drive, and can't start up. Apple said will replace the hard drive for me, but this should not be the case for a 47 days laptop.

Camera basics: shutter-speed, aperture and ISO
In this article, I’ll introduce you to the basic elements that you can use to control exposure in your shooting. If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
Professional video camera
A Professional video camera (often called a Television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film). Originally developed for use in television studios, they are now commonly used for corporate and educational videos, music videos, direct-to-video movies, etc.
There are two types of professional video cameras: High end portable, recording cameras (essentially, high-end camcorders) used for ENG and EFP image acquisition, and studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals. Portable professional cameras are generally much larger than consumer cameras and are designed to be carried on the shoulder.
Technology
It is common for professional cameras to split the incoming light into the three primary colors that humans are able to see, feeding each color into a separate pickup tube (in older cameras) or charge ...
