How many times have you taken a picture and then, when you looked at it, you got disappointed because it did not render the beauty you saw at the moment of shooting? Yet, the scene you shot and the scene you saw were exactly the same. This is no surprise, because a camera sees the world differently than our eyes. I will now try to sum up the major reasons. This will help you render reality more accurately in your photos or taking advantage of these differences for creative artwork.

For starters, we have two eyes, while the camera has just one lens! Thanks to our stereoscopic view, we can perceive depth. This is because we can see the world from two slightly different points of view. Each of our eyes sees reality from a slightly different angle (parallax angle). Our brain then elaborates the information coming from both of our eyes permitting us to perceive depth. This is impossible for a camera, and that's why pictures tend to be "flat" (actually they are). If you try to cover one of your eyes, you will get the point. In this case, of course, your reasoning will still tell you if an object is nearer than another (e.g. a nearer car will appear bigger than a further away one). However, you will not perceive depth as before. Try catching a ball someone has thrown to you: you will probably miss it!

Depth of field is something unknown to our eyes but always lurking in the camera. When we look at something, be it near or far away, we instantly focus it. The camera usually can focus either the near objects or the objects far away, but not all of them contemporarily.

Another striking difference between the eye and the camera is their ability to see contrasty scenes. In each scene we look at, there are some parts darker and other parts brighter. Our eyes are usually able to see correctly both of them, virtually simultaneously. But the camera can't. If you ever tried to photograph a person in the shadow with a bright background (see an example), you surely noticed that either the person was rendered too dark (underexposed) or the background too bright (overexposed). It was not your fault: it is inherent in the medium used to record the image, be it a classic film or a CCD sensor.

What about color? Colors are seen differently, too. Besides, diverse films or CCDs see colors differently. Even our field of view is different from the camera, because the camera's field of view depends on the lens mounted on it.

At the end of it all, are these differences good or bad? It depends. If you are struggling to make the scene appear the way it does to the eye you will have to work hard to overcome these different characteristics. On the other hand, if you want to be creative, these same dissimilarities are a precious opportunity.

Battle of the video sensors - CMOS vs CCD

The image sensor is the camera component which captures light and begins the process of converting it into a digital image. There are two types of security camera sensors: CCD (charge coupled device) and CMOS (complementary metal oxide semiconductor). Which of the two you choose depends on your application.

First a little background on each technology.

Wtih a CCD sensor, every individual pixel's charge is transferred through an output node, which is then converted into an electrical signal. The signal is then buffered and sent as an analog signal. Because of the pixels can be devoted to light capture, and the image quality is usually pretty high.

With a CMOS sensor, every pixel performs its own charge-to-voltage conversion, and the sensor also performs amplification and noise-correction. The sensor also includes digitization circuits which allow the component to output information in a digital format. Because of the complexity of this design, the area devoted to light capture is reduced. And because each pixel must perform its own conversion, uniformity (image quality) is lower.

The production cost for both types of sensors are similar, but CMOS sensors sometimes require additional support chips to optimize image quality. CMOS sensors are great for devices that require speed and low power consumption, while CCD sensors excel in image quality and low light performance.

While both CMOS and CCD sensors have matured a great deal in recent years, when it comes to security cameras, I prefer CCD for outdoor applications and CMOS for indoor IP camera functions. Let me explain why.

In the still camera world, CCD and CMOS are almost identical in terms of performance. In fact, CMOS sensors are attractive in this space because of their much lower power requirements - an important feature for devices which run on batteries. In the security camera world, I find that CCD sensors outperform their CMOS counterparts in several key metrics.

The first and most important is light sensitivity. If you need a security camera with superior night vision capabilities, CCD is the way to go. The CMOS cameras I have tested, with or without IR illumination, were almost completely blind in the dark. Cameras with CCD sensors are very capable in low light applications, and are terrific when coupled with infrared illumination. If you need to record in low light situations, CCD is the way to go - do not even consider CMOS.

The second factor to consider is image quality. In the security camera world, while both technologies are getting closer, CCD still has the edge when it comes to image quality. This is because CCD sensors exhibit less image noise than their CMOS counterparts.

Why would one consider purchasing a security camera with a CMOS sensor? Mainly because these sensors are more prevalent in IP Security Cameras - that is, cameras that are equipped with built in web servers and communicate using the IP protocol over CAT5 cabling. These cameras tend to be very affordable and are great for indoor applications that require web based video streaming.

In conclusion, CCD sensors are the way to go for outdoor applications, low light scenarios or when a higher quality image is required. CMOS sensor based security cameras should only be considered for indoor applications with decent lighting conditions.

How to I play a playstation game on an emulator if it is in 10 parts?

it is in 10 folders and each one has 3 files in it that are .ccd .img and .sub

If you use Winrar and all the files are inside the same folder, then you open the first file of the game Winrar will automatically open each portion of the file and attach them appropriately.

Then it will be a complete game.
