This blog, I decide to write something about megapixels of a camera and I am sure it would be an interesting topic for someone. However, before talking about that, I'd like to introduce that there are two types of cameras: film and digital cameras.
Today, digital cameras are the rage. In addition, digital cameras is divided into non-SLR digital and digital SLR cameras. As I mentioned the word "non-SLR digital camera", it stands for non-Single Lens Reflect digital camera; and "DSLR camera" stands for Digital Single Lens Reflect camera. I am not going to talk more details between two kinds; I might talk about it in the next blog. One little thing I'd like to say is non-SLR is kind of scientific words; we may see it under different names depending on different companies such as power-shot camera from Canon, cyber-shot camera from Sony, point-and-shoot camera from Nikon, etc.
I believe that a lot of people own a non-SLR camera and I think you do too. The reason why I chose megapixels as a topic is that the term megapixels is only used when talking about digital cameras. At the end of this blog, you guys will know the meaning of megapixels.
In fact, megapixels is one of basic elements of a camera and usually goes together with the word "sensor". Instead of film, a digital camera has an imaging sensor which is located inside the camera and contains an integrated circuit with millions pixels that records an image. In other words, a digital camera captures pictures through that sensor. You may see an amount of sensor units somewhere on the surface of a camera, example 5.1 MP, 7.2 MP, 12.4 MP, and the range of megapixels is between 0.3 and 20. So, if your camera has 10.0 MP, that means your camera has 10 millions pixels on its sensor.
A sensor is not the only element to determine quality of a camera. An effect of amount of megapixels on a picture is that it represents how large of picture. The more megapixels a camera has, the bigger resolution the camera has and, thus, the larger the photograph will be (Big Sky Fishing...) But a lot of people buy cameras depending on amount megapixels of the sensor. According to Jakob Jelling in his article "The Relationship Between Megapixel and Image Quality" in Snapjunky.com, he notes that
Despite what is commonly thought, choosing a camera according to how many megapixels it has is not correct. One camera which has more megapixels than another is not necessary better since megapixels is not a measure of quality and, therefore, a camera which offers more of them than another does not guarantee a better image. This way, those who are looking for a new camcorder and find out that some of them offer more megapixels as one of the main advantages, should ask how does that affect the image quality. Image quality and the amount of mega pixels are two different things, and one of them does not necessarily imply the other.Through this short blog, I hope you guys understand a little bit clearly about the megapixels on your camera. Even though this blog doesn't provide much knowledge and information about photography, but I believe after reading this blog, you may feel curious about what is next.

In your introduction you seem to reference readers as "you guys," but I think that might be to intimate for a blended scholarly/real world blog. Would you want to choose a topic that is interesting to "someone"? That sounds too pessimistic, really. Don't shoot yourself in the foot here with low expectations of what readers want or need. We'll be with you when you take a topic like megapixels and just run with it. You don't have to keep addressing the audience. Think about phrasing that is engaging and that informs without over explaining...we can chat about this even more next week.
ReplyDeleteI meant, "too" intimate...
