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.

Overview
WebP is a file format which uses both lossy and lossless compressions to encode the files. It was developed by Google in order to facilitate the work online which can be done quickly and easily with this extension. This is a sister project of WebM Multimedia container and it produces high quality of images. It is claimed that it can reduce the file size by 34% without affecting the quality of a photo. Due to this reduced size, online work can be done in less time as these files can offer high speed over the Internet due to small size. This format provides add-on support to the lossless algorithm, metada, transparency, colour profile and animation.
Technical description
Intra frame coding that is used in video format and the resource interchange file format, are base for its lossy compression. Only 16,383 pixels can be used to represent the side length of an image. Besides this, it is based on block prediction in which every block is forecasted as per the values, from the three blocks above it and from a one block to the left of it. Horizontal, vertical, DC (one colour) and Truemotion are the four basic modes of block prediction in this extension. Animated images can also be produced using WebP and this is a substitute to famous GIF format. It comes with many improved features. For instance, 24 – bit colour with transparency, joining of frames with both lossy and lossless compressions in the same animation and providing support to seek to a specific frame.
