Is not like you have a lot of other options...
2010-09-04This device does what it's advertised to do. 1) you set your Nikon to "remote", 2) compose your shot, 3) click and voila... you have a picture without camera shake artifacts. You must have a remote shutter control if you're planning on taking night shots without flash or long exposure shots. However... there is one very anoying detail: the device doesn't seem to work well from behind the camera. You'll have to keep pressing the buttun until you find that sweet spot where the infrared sensor on the *** front *** of the camera is aligned with the remote; i've used it for only a couple of days and I already missed a few "perfect shots". Now that I learned the trick, I can work it out... but still, very annoying. Also, the device is too small and too light; it's easy to loose, and hard to find in your packed camera bag. All in all, you still have to get one of these; I wish there were more options out there, though.

Awesome!
2010-09-03This remote works well right out of the box (battery included). It did take me a couple minutes to figure out I had to change the shooting mode on my D40, but since then the remote has been working great. Very convenient and I like that it will activate the shutter from any direction (including from behind the camera). Easily worth the money.

It's Ok, but the range is short
2010-09-01We chose this product to take with us on our trip to the Canadian Rockies (we wanted pictures of the two of us while hiking). It worked most of the time, but you need to be fairly close to the camera and need to have a direct line of sight to the sensor. Overall, it's just ok.

Good product for simple usage.
2010-08-30This product is good for your nikon cameras and is really easy to use. Simple button for taking pictures. Only down side is that there is only one button to use. It's the only wireless remote from nikon for most of there cameras and I wish there was more of a variety.

Great
2010-08-29This item works exactly as described. I've used it for more than 6 months with a Nikon D90, and never had any issues with it. I've used it up to 15 feet away from the camera, and never had a problem. It is simple enough for my 6 year old to use.

Digital camera batteries
Batteries are vital for all photography and makiing sure that you have a spare set is essential if you intend to take alot of pictures. Print digital also recommend that when deciding upon a digital camera keep in mind what sort of batteries it takes. Does it take rechargeable batteries, are the batteries built and do you have to plug it into the mains, or does the camera only take standard batteries, if so then it can become exspensive if you are a keen photographer and use the camera alot.
There are three types of rechargeable batteries: NiCD, NiMH and Lithium-Ion. Nickel Metal Hydride are the most popular rechargeable batteries at present. They hold more charge than their counter parts NiCD and don't suffer from memory effect. The one small down fall of these batteries is that they will loose a small amount of charge even if they are not being used, so be sure to check the batteries before using them.
When you purchase a new digital camera make sure to ask what type of battery ...
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 ...
