In a world of low-priced cameras, it is good to know that are also options for people who take their photography seriously, but don’t have thousands of dollars to spend on a camera. For these photography "purists", there are SLR Digital Cameras. SLR means Single-Reflex
Camera and the digital versions of these cameras allow the individual to take high-quality pictures using a variety of different lens types.
The following are some important questions that every one considering a digital SLR camera should ask before making this exciting purchase.
Auto-Focus or Manual Focus?
Auto focus SLR cameras provide you with a tremendous amount of convenience when it comes time to snap your picture. However, there are several drawbacks to auto-focus cameras, including:
• Auto focus systems are run by electronics, which can fail you at the worst possible time
• Auto focus cameras burn through batteries faster than manual focus models
• Auto focus cameras can be noisy
• Sometimes the lasers that control auto focus lenses see things differently than they human eye
Individuals who like additional control and customization options may wish to choose a manual focus camera. Manual focus SLR cameras allow the user to control shutter speed, aperture and the zoom focus features. Disadvantages of manual focus cameras include the steeper learning curve and the additional time it takes to properly set up each shot.
Can you auto-preview pictures with a digital SLR camera?
Yes. Digital SLR cameras offer all of the convenient features found in standard digital cameras, including the ability to preview pictures on the camera’s screen, cycle through photos and delete unwanted images and easily transfer photos onto a memory card or computer.
What are the Most Important SLR Camera Accessories to Buy?
Everyone who takes their camera on the road with them should have an extra battery always on hand. (NOTE: Be sure to keep your spare battery properly charged at all times.) Also, a neck strap helps you keep your camera handy while on the go. Finally, a tripod is a great choice for anyone who plans on taking posed or stationary pictures with their Digital SLR.
What are Gray Market Cameras?
When you a buy a Digital SLR camera online or at a traditional camera store, you will either be purchasing a gray market or warranty-covered camera. Both are the actual manufacturer’s product, but gray market cameras are generally not covered by a warranty (and are less expensive as a result).
How much do Digital SLR Cameras Cost?
Digital SLR cameras are available at a wide variety of price points, from $400 to $5000. The price of the camera depends upon the features included and the zoom capability of the lenses. Price may also be dictated by the lens package included.
How much Memory is Required?
Although the amount of memory is a personal choice, experts agree that a one gigabyte card is the most appropriate place to start. A one gigabyte memory card will hold hundreds of even the highest quality images comfortably.

Home Theater System: -quick Overview of the Major Components
Going out to the movies is becoming a very expensive activity. Not only have ticket prices gone up in the last few years, it seems that drinks, popcorn and candy have all had price increases. Couple this with the drop in prices on high end electronics and recent advances such as Blu-ray, and it is no wonder that ticket sales and continuously been dropping off as more and more people are opting to set up "Home Theaters".
Today's dream home theater consists of three things. First a television or projector, a 5.1 or 7.1 sound system and media playing device, for more details visit to normally a DVD player but more recently Blu-Ray players. This is a simplification of the home theater setup, there are a multitude of options and decisions to make in creating your dream home theater. This article will help you grasp a simple of understanding of the major components.
Television or Projector - There are plenty of options here. When considering a television, you must decide on whether you want a plasma screen, and LCD, DLP, or rear projection television. CRT or Cathode Ray Tube televisions are almost obsolete in today's home theater systems. Each of the aforementioned types has its own advantages and disadvantages. If you want a screen with great flexibility in placement, high quality picture and the price is not a major factor - then a plasma screen is your best option. If space is not a major factor and price is, for more details visit to you can find great prices on high quality rear projection television sets. In either case you need to purchase a high definition television, they are almost standard in larger screen televisions today. High definition is defined by a pixel count of 720 dot per inch (DPI) or higher. In order to take advantage of Blu-Ray quality, your TV should have a pixel count of 1080 dpi. Among 1080dpi sets you have a choice between 1080i and 1080p. The "i" stands for interlaced, and the "p" stands for progressive scan. These terms refer to how and how often the pixels on the screen are refreshed. 1080p televisions provide a higher quality picture, and will of course cost extra. The extra cost is well worth the cost in my opinion. The most recent advance in high definition televisions is 120 Hz sets, these new sets are supposed to better handle motion, especially in regards to watching sports.
Sound System - This is potentially the most complex portion of your dream home theater setup. I say potentially because you can purchase a high quality "home theater in a box" and end up with a respectable sound system for your home theater with minimal fuss, or if you want to extract the maximum quality sound out of your system and are willing to pay what it takes; then building your own system from quality components is definitely the way to go. HTIBs or "Home Theaters in Box" are sometimes maligned by audiophiles as not being serious home theater sound systems, but a little research will show you that in recent years these pre-packaged systems now have components worthy of being part of a dream home theater system. If you want to build your own system the options and decisions you'll be faced with are numerous. But the homework and research is well worth the final reward. Having a high quality picture certainly makes watching a film more enjoyable, but a great sound system takes you out of the confines of your living room and puts you in the middle of action.
Media Player - Normally this is a DVD player or more recently Blu-Ray players. When buying a DVD player, you should choose one with a video signal upconversion to 1080p. Ask your salesperson if the player uses Faroudja Video Processing, this is considered the best upconverting technology. Most Blu-Ray players will upconvert DVDs. If you are willing to pay between $200-$500, then a Blu-Ray player is definitely worth considering. The format war between HDTV a Blu-Ray is over, so a Blu-Ray is a safe bet. Blu-Ray is also capable of providing highest quality lossless audio (True-HD or DTA-HD Master Audio), allowing your dream home theater sound system to really shine. Eventually Blu-Ray will become the standard home video standard, but the good news is that they will play all your old DVDs as well. But if you are like me, once you've gotten used to Blu-Ray quality, it's hard to go back plain old DVDs.
This is just a quick overview of the major components. There are several other things to consider when building your dream home theater, such as cabling, speaker wire gauge, dipole /bipolar speakers vs. direct radiating just for starters. My recommendation is that if you research and make a well thought out decisions on the major components mentioned here, then many of the choices on the ancillary equipment and parts will begin to fall into place, and creating your dream home theater will be that much easier.

Toshiba Regza 42X3000P

1080p was a fixed requirement to have a test bed for full HD devices like the Sony PS3 and HD disc players.

Toshiba managed to strike a balance between necessary quality and saving on unimportant aspects to come in at a low price point for a 42 inch full high resolution TV.
Logitech Harmony 1000
I remember the days when a universal remote meant sitting down with a book of codes and entering them all until you found one (hopefully) that worked with your TV or other components.

Read on for all the details on the Logitech Harmony 1000.
