Currently the DSLR has two main types. One has full screen, its sensors size is about the same as the traditional 35mm flim base camera. The other is APS-C, its sensors are smaller compared to the 35mm, and this is primary due to cost consideration
About lenses, there are man types of Lens. Depending on whether it can or cannot zoom in and out, it can be categorized into two types, the fix lens and the zoom lens. As in the name of the lens described it all, the Zoom Lens can zoom in and out. It allows the photographer to be able to compose a subject matter by zooming in or out to best compose the picture that he or she wants to establish without having to move himself/herself physically from the subject matter. By the way, a zoom lens is very convenient, but the fix lens produces a higher and sharper photo image.
Depending on whether is has assisted auto-focus, the lenses can be differentiated into auto-lens and manual-lens. When using an auto lens in shooting, the camera body will automatically focus. When using manual-lens, then everything will have to be manually set up from depth of field ring, aperture, and focus.
Photography is getting very popularized. It is no longer something only limited only the professional photographer. Automated idiot proof digitized photo equipment has made it accessible to just about everyone to do the point and shoot. But I think the real joy of photography is to be able to take a photo to reflects some emotion, tell a story, or relate an experience. I hope that more and more people will take up photography as a hobby sometime in the future.

Aperture and Shutter Speed
When we combine aperture and shutter speed together, then we have "Exposure".
The correct aperture and shutter speed dictates how well the photo will be. A good photo needs the right about of light. The right amount of light is done thought the correct setting of the aperture and the amount of time we let the light coming through.
Aperture is the hole where we let the light through in the camera. The larger aperture number makes the smaller the aperture opening, and the smaller the aperture makes the larger aperture opening. The aperture size dictates how much light is let into the camera at a fix period of time.
Use a tap to fill a bucket of water as an example. Let’s say to take a perfect exposed photo is like to fill a bucket of water, then aperture will be the size of the tap, and the amount of water flowing out of the tap will depend on how much we open up the tap. So if I were to open the aperture to 2, then the volume of water will be huge. Filling the bucket of water may take only 5 sec. If over 5 sec, the bucket will over flow, and there is too much light. Then it will cause "over exposure" on the photo, and the photos will show lots of "white". If less then 5 sec, the bucket will not be full, and the photo will be under exposure. The photo will appear dark.
If I were to close the aperture down to 11, similarly with a smaller tap, the flow of water will be significantly smaller. It will take longer to fill up the bucket. It may take 10 sec. With the same logic, if over 10 sec, the photo will be over exposed. On the contrary, exposure time less then 10sec will cause the photo to be under exposed.

Ice Cream
Ice cream is a nice snack. Most people love to have it when drastic sun is hanged on the sky. Ice cream makes people have temporary refreshing. The temporary feeling is so great. I believe that many had the experience that wolfing down ice cream under a big sun and then a big headache explodes from throat to brain. This is just the enjoyment of ice cream.
There are various flavors of ice cream in the convenient stores, therefore, it is available to enjoy ice cream anytime only if you are willing get to the stores and choose what you want when the desire occurring. As a modern people can easily enjoy ice cream, but the amount of tasting is need to be controlled. For the reason that ice cream can cause the tonsil to be weak. A weak tonsil is welcoming any kind of germs or virus to easily invade whose throat.
Every time when I have ice cream without limits, my throat always gets irritation. The unique symptom is about to run a temperature or cough incessantly. Every time when I unfortunately have too much ice cream, only antibiotic is my savior. In order to avoid next temperature, learning to control my mouth is an important course.

If I Were the Grim Reaper
Most people will probably have a very negative impression of Grim Reaper. Perhaps the Reaper represents a frightful feeling. However, if we look at it objectively, the Reaper is actually performing a duty that he is supposed to do. All things must come to an end, so that new things may come. It is the law of the circle of life.
Therefore, if I were to be the Grim Reaper, I will want to modernize 3 things: No.1, have a new major image. I will make over to make myself more approachable and friendly. I will get rid of the black cloak, and will not appear as a skeleton wielding a large scythe. These medieval outfit just looks too dirty, messy, frightfully depressing, and very unfashionable. I would want to appear like an average young boy and stylish person on the street. Where I won't be standing out like a sore thumb on the street.
No. 2, Establish a team to get the job done. Wielding a large scythe, getting the job done in person is just too tired. I would try to recruit some capable souls from those souls that I have collected. Then train them up and get the job done through them. Sort of like my deputies. As for me, the real Grim Reaper, will just sit in the "reaper's office" and monitor the works and issues instruction from my desk top computer.
Last but not least. I want to make a major break through. That is … to give advance notice to the deceased person. So that the person will ample time to bit farewell to the person's family and love ones.
With the above changes, would you change your perception of the Grim Reaper? By this literature, I want to wish all of my friends to have a wonderful and productive life in the future, live life to the fullest, and have no regrets when the Grim Reaper comes knocking.

How to Prevent the Low life
How can we prevent or avoid this kind of low life? It is really hard. As you don’t really know who around you is the low life, what, when he or she will act, and where low life is coming from, it is always too late when you realize it. There are few ways I would like to suggest: First of all, don’t trust others too easily. A low life always tries to make friend with you in order to win your trust. Then, you have to consider if the one a low life by listening to his or her word about others, because low lives enjoying speaking ill of others. Finally, just do remember, a proverb says: who chatters to you, will chatter of you. Because “words cut more than swords,” low lives indeed stir up a nice society and bring out lots troubles.
Low Life
As a proverb says that It takes all sorts to make a world. Since we have gentlemen and ladies in our society, unfortunately there must be some, or a big number of “low life” around us. In our history of more than 5,000 years, a lot of tragedies were caused by “low life.” For personal desires, hope for power, fortune, or even love, those low lives even scarified welfare of others to satisfy themselves. Not only in our history, low life exists in modern society, too. They always hide themselves in dark, waiting chances to play nasty and dirty tricks.
These low lives are everywhere, such as in working place. They act as long as there are human beings, especially when the people are the unaware or naive. Low life is generally vicious, cunning and deceiving. They love to create confusions, unrests, disharmony, and misunderstanding among people. They also enjoy stabbing on other’s back, and sabotaging relationship. Based on the misfortune of other people, they happily and lushly thrive.

Gentleman
There are all sorts of people around us in our society.
In general, most of them have a positive out reaching spirit and kind hearts. They, as a result, can be considered as Gentlemen or ladies. This inner positive quality can be easily discovered trough the action and behavior of an individual. For example, a gentleman is always optimistic with positive thinking and progressive action. He or she doesn’t envy others. He or she doesn’t have a bad mouth to others. Nor does he or she create misunderstandings. On the contrary, a gentleman is always willing to stand up for or offer helping hands to those in needs. As we all know, in Taiwan, there are many gentlemen who always help other people. In these days, they even donate money or relief goods to the earthquake and tsunami victims in Japan. Their behavior is really warmhearted which also reflects the positive side of our society. If this kind of thoughts can be practiced by everyone, our society must become more harmonious.

Humanity
Humanity is lazy. This way of saying is a very common talk we can often hear. In order to enjoy lazy, people have invented many tools, equipments, facilities…etc since old age. All the inventions come from various impossible fantasies, and be achieved by the patient men.
Humanity is greedy. This way of saying is anther very common talk we can often hear. In order to get more power or properties, various dirty tricks are devised and used. It’s cannot be help, it is a money-priority society and never change since old age. For better life, it can be understand that most people are reckless of struggling for power and properties, but is uncertainly accepted.
Humanity is strong. It is a saying goes, without some cold biting, nothing fragrant plum. People always have fulfillment after they experience some enormous changes or endeavor to finish something. They also develop stronger mind in the processes. As the reason, now we can read many successful and impressive stories.
Humanity is also fragile. People having not strong sensitive mind are more then who have strong and optimistic mind. A real situation we can easily find that same-thinking people always converge. It just like a saying goes, birds of a feather flock together. Optimistic people gather for possible actions and sensitive-mind people gather for gossips and rumors. So~what humanity you are ??

Health Products
Modern people frequently catch a cold and flu. It might be the dirty air and water or pollution food or working pressure caused people to have weak body. Health products are getting more and more popular in many stores. Health products manufacturers also product various health products for people’s needs. I also have many kinds of health products everyday, such as vitamins, clam essence, and ginseng. Actually they bring me more energy at daytime and cost me much monthly.
Why do modern people need the extra nutrition? Ancient people were alive well without those kinds of pills, but why do modern people need the extra nutrition? This question has confused me for a long time since the first time my mother forced me to swallow the big size of vitamins B in my childhood. My mother always asked me to swallow various vitamins and health products, but did never told me that the throat can open. The vitamins usually spurted from my small mouth.
I almost exhaust energy every day for hard working and studying. Now I finally know the reason I need to have health products. I also accept the statement, modern people always spend money buying health, because maybe I am one the people.
