Digital photo
has brought about a great revolution in the world of capturing the memories. The pictures are taken from behind the lens but they are complete representatives of what the photographer feels, thinks and perceives about the visual before his eyes.

The photographs are no longer being transferred on a film; rather they are being transferred on the photosensitive digital sensor that changes the analogue picture into the image with high digital quality. Where there was little room for creativity in the traditional photography, the digital photo relies on not just the click of the camera but also on the creativity of the photographer.

The world of pixels

The picture elements generally referred as the pixels are the major constituent elements in the digital photographs. Generally the digital photo is captured with the help of the system referred as 24 bit RGB, which extends colors to each pixel in the picture. Thus, the pixels are said to have a gradation of 256 colors that is related to red, blue and the green colors. In this context if we consider the gradation of orange it will have 255 Red, 102 Green and 0 Blue?

The gradation for the lighter shade of the pink will be given as 255 Red, 153 Green and 204 Blue. By making use of all these colors 16 million colors can be generated that are perceivable by the human eye.  In the latest version of the computers the screen color is said to be 32 bit. The reality is not the same. Actually the screen colors are just 24 bit RGB added with a transparency channel known as alpha. The conventional computers have a higher setting of the Truecolors.

The size of the digital photo

In order to define the size of the digital photo, pixels are used. It is the combination of two numbers in which the first number expresses the width of the photo while the second one refers to the height of the photos. The image sensor features of the digital camera are also known as pixels.

Mega pixels

The unit used for the resolution of a digital photo is refereed as “megapixels” which is actually the total sum of the pixels in the photo. Therefore if a photograph taken digitally is considered to have a size of approximately 2048 pixels x 1536 pixels in size, then the total is going to be the product of the both numbers and will said to have a resolution of 3 megapixels. The rating and the reviews of a camera are according to its resolution.

Usually this range is from 768 to 3072 pixels to1920 x 1080. Thus, if you view any image it can be reduced in size. On the other hand the unshrunk pics cane is seen by simply scrolling from the extreme top to the bottom.

Conclusion

Digital photo is fun. It can be a phenomenal thing to capture the memories through the digital photo if you can learn to master the technique.
