When capturing images with your digital camera, if you cannot open the images, you need to make sure about the compatibility of the computer operating system.
Are you familiar with the ISO functionality? You might want to try using your digital camera in a manual way. the ISO in digital technology is merely an argument in his address that simulates analog behavior, thus facilitating a reference.
Usually the best signal / noise ratio of a given sensor is often called the ISO rating of a camera, and this is usually 100, some 200 ISO and often coincides with the lowest ISO selected by default. The sensitivity of the sensor is unique and thus fixed cannot be changed as analog film, however it does is amplify the signal optimized steps so you have ISO, 100, 200, 400, 800, 1600.
And the problem is that by amplifying the signal / noise ratio is not constant, and as they amplify the S / R decreases by a lot of factors (electronic, quality components, software, etc) so that there is an increase noise for the same signal. The result is that there is a higher ISO noise. In consumer camcorders is unusual ISO control. In other professionals who can control the ISO. The solution to get more light without increasing the ISO is that you download the speed of film, considering that below 1 / 25 is beginning to be problematic.
The image light passing through the lens is reflected in a filter RGB (Red-Green-Blue), which breaks up light into three basic colors: red, green and blue. This division focuses on a ray light sensitive chip called CCD ("Charged Coupled Device"), which assigns binary values to each pixel and sends the digital data for image coding and subsequent storage.
Definition of digital camera photo
Going to the very beginning, a digital camera is an electronic device that captures images and saves them in digital format (computer) with a high resolution, also in most cases records video but with a lower resolution. Digital cameras have the same use photographs that were given to roll-based cameras, but have the advantage that the vast majority of the picture can be displayed on a small LCD screen that integrate and integrated via buttons, delete, copy, zoom ("Zoom"), etc. among other functions.
The digital camera has replaced the use of mechanical cameras to roll. General characteristics of a camera:
- It has a resolution usually high, depending on the model up to 12 Mega pixels.
- The basic video is low resolution, as its primary objective is not to record it, but for recreational purposes is a good option.
- To capture images from a distance, you have the option of 2 types of approach: optical and digital.
Parts that make up a digital camera
Internally, it has the appropriate circuit for image sensor and transmission to the computer.
