Overview

These files are commonly termed as ‘ping' and they store the raster files using lossless compression. It came into existence in order to replace the GIF file format as they both have the ability to show transparent backgrounds. Furthermore, it was an enhanced and improved version of Graphics Interchange format. It supports different types of photos. The first one is palette-based photographs that can either have palettes of 24-bit RGB or 32-bit RGBA colours. Second is grayscale images which may or may not have an alpha channel for transparency. Lastly, there is a full-colour non-palette which is based on RGB/RGBA pictures. There is one limitation of this type. It does not support animation like GIF. Besides this, it is non-patented which means there are no copyright limitations.

Technical description

The expanded features like 8- bit channel for transparency and 24- bit RGB support make PNG more popular. The files stores in this format allow the fading of colours from opaque to transparent which is not present in the preceding format. CMYK does not offer support to this extension as it was developed for transferring of files over the internet, not for professional-quality print graphics. It stores information like textual comments, integrity checks and encoded basic pixels in its extensible structure of chunks. It always starts with an 8-byte signature followed by a series of chunks. A chunk furthermore comprises of four parts- length (4 bytes), chunk type (4 bytes), chunk data (length bytes) and CRC- Cyclic redundancy checksum or code (4 bytes).

Overview

These files are also termed as Radiance HDR or HDRI. This format is used to store raster images or digital photos. In this, there is a grid of pixels where every pixel depicts a solo color within the image. Additionally, it has the ability to enrich the color and bring brightness to the pictures. Furthermore, it works well while processing the dark shadows and also on the washed-out areas of a picture. Hence, it is very useful to capture real-world scenes that have high brightness or direct sunlight and as well as extremely shady area or fainted nebulae. These images are the result of numerous different and narrow range exposures of the same matter.

Technical description

HDR images offer the same luminance(an amount of light that is either emitted from or passes through or reflected from a particular area) that of the human visual system. ‘Stops’- Exposure Value differences are used to measure the dynamic range of photography. To double the amount of light, there should be an increase of one exposure value or one stop. Contrary, to decrease the amount of light to half of its value, there should be a decrease of one EV or one stop. Consequently, the darkest parts of shadows require high exposures when something in detail is to be revealed and low exposures are needed when there is a high level of brightness. It uses bracketing which means several shots are taken of the same subject using varied camera settings. Then these images are merged using a photo manipulation program to produce a single image.
