It is imperative to understand the technology of DSLR cameras before contrasting the differences between to models.

Compare digital SLR cameras of Canon and Nikon

Canon Vs Nikon - Digital SLR Camera Comparison

In the 'point and shoot' units, the scene depicted in the viewfinder is not the same as what come through the primary lens. The viewfinder portion is not indicate of final product in traditional digital cameras. Therefore, in the DSLR cameras, the images are the same. Therefore, the photo taker will be able to take a picture that will turn out the same as what is seen through the viewfinder. This visualization makes picture taking much easier and more accurate.

There are three basic categories for both Canon and Nikon for SLR digital categories. Beginning with the amateur level machines, the Canon Rebel XS (1000D) and also the Nikon D60 fall into that category. There are many differences between the Rebel XS and Nikon D60. If you have older Canon lenses you want to use with it, the Nikon D60 will work with most of them; while the older Nikon lenses may not work with the Nikon D60.

The next category of these cameras is for more professional use. These are usually larger and more expensive. They require some expertise to use effectively. Cameras that fall into this category are the Canon Rebel T1i 500D as well as the Nikon D 5000. The Canon Rebel T1i and the D5000 are actually very similar in their capabilities; although the ISO range varies. The D5000 range is 100-6400 while the T1i has a larger range of 100-12800.

Finally, there is another category to compare digital SLR cameras. They fuse together several of the features from each of the previous categories. These can be used by amateur photographers who want to take more professional quality pictures. In this category, the Nikon D300 and Canon 50D would meet those needs. These are both really good cameras and are almost identical in their features. There are a few subtle differences; the Canon is actually lighter at 29 oz than the Nikon at 32.6 oz. Also, the ISO range is slightly different; the Canon ISO boasts 100-12800 where the Nikon range is 100-6400.

Global Warming - The Countries Most Affected

A worst case scenario scientific report predicted that we may very well be living on the South Pole in a hundred years. And even though many people find the idea too ridiculous to contemplate there are others that already feel the effects of global warming.

Some of the parts of the world already feeling the effects of climate change are;


Asia - Bangladesh and India have heavily populated low lying land. Rising sea levels and increase in rainfall due to global warming an increasing problem.

Global Warming - The Countries Most Affected

Africa - Increasing drought in an already food short continent.

Australia - Hotter conditions are fueling massive bush fires that are occurring more frequently.

Pacific and Indonesia - Recent earthquakes have caused a major disaster in Indonesia and Samoa is still mourning the after effects of a tsunami, as a result of an offshore earthquake. Rising sea levels also threaten some islands in the pacific. Predicted to be completely under water in the future are Kiribati, Tuvalu and Marshall Islands.

Europe - Yearly flooding is now the norm when snow in the alpines melts. Greece and Portugal are regularly experiencing wildfires during summer heat waves.

Latin America - The Amazon, already threatened by encroaching development is also threatened by increasingly dry weather.

North America - Hurricane Katrina is the worst experienced so far due to rising sea levels and a massive storm surge. The threat from hurricanes is now a yearly occurrence. Bush fires in California have claimed many lives and rising sea levels is also a problem.

The picture is constantly changing and the latest prediction, within the next 20 years the Arctic will be an open sea during summer. A disastrous outcome for polar bears, arctic foxes and many other animals that call the arctic home. The full effect on the rest of us still largely unknown

Refurbished PS3 Review

If you are looking to buy a new PS3 did you ever think about purchasing a refurbished PS3 and saving some money? There are advantages and disadvantages of buying a refurbished unit just like with anything else. Sometimes trying to find not a brand new unit is harder, but if you are lucky enough to find a seller that does, it could save your pocketbook.

Let's look at each pro and con below to review.


The biggest pro is that you will obviously save maybe 0 to 0 off the price of a new PS3 because it's not brand new. A refurbished unit will typically come directly from the manufacturer in which they received it back as a return and then tested it out to make sure everything looks good and works. The packaging, manuals, and everything else that comes with a new unit should be included along with a warranty. There may be slight blemishes from the unit being handled, but there should never be anything major like scratches or nicks.

Refurbished PS3 Review

One of the disadvantages of buying a refurbished PS3 is that it may not come with a full manufacturers warranty. Typically if you bought a brand new Playstation 3, you will probably get a full 1 or 2 year warranty directly from Sony. When buying a refurbished unit you may only get something like 60 to 90 days from Sony. That's really the only downside of not buying brand new as everything else should be identical.

If you are not concerned about having an extended warranty on your PS3, then buying a refurbished unit could save you a couple hundred dollars. You simply have to weigh out the pros and cons and decide whether or not a new or refurbished PS3 is for you.
