| Overview |
| This EXR extension stores the raster or bitmap images, which are dot matrix structures. It is also an open standard format with a free software license. It works effectively with HDR images(High Dynamic Range). The pictures that are stocked using this format can have either lossy or lossless compression. It has the capability to keep photographs of high luminance and colour. It supports pictures of multiple layers that possess high quality. This format is used by many photo editors in order to add visual effects as well as animation due to its flexibility in compressing the images to both lossy and lossless algorithms. |
| Technical description |
| EXR can support multiple channels with varied pixel sizes that are 32-bit and 16-bit floating-point values. It contains arbitrary channels and it can cover multiple points of view. For instance, the left side and right side camera images. Composting is an enhanced feature in this format which allows assembling of numerous pictures to one final photo. There is no need to make separate files for storing the information of arbitrary channels like diffuse, alpha, specular; as all can be combined to one file of this type. A compositor can also modify the specific channel if he is not satisfied with the current appearance of specular reflections or specularity. It has different compression methods for varied types. For grainy images PIZ algorithm is suitable and images that are without a lot of grain, ZIP compression works the best. |

| Overview |
| GIF is an image format which is known worldwide and it is used as a second option after JPEG. It offers high portability between OS(Operating Systems) and applications. Each picture can support up to 8 bits per pixel, as a resultant, it enables an image to have a separate palette of up to 256 distinct colours that are taken from the 24-bit RGB colour space. Furthermore, it is commonly used for web graphics, logos with solid colour and also for animated images. These files are saved as ‘animated GIFs' and it displays general animations on websites. Besides this, this format has the capability to blend varied colour backgrounds due to the presence of transparent pixels. It should be noted that pixels should be either fully transparent or opaque so that it doesn’t result in the faded picture. |
| Technical description |
| GIF is an inadequate format for colour photographs due to palette limitations. It enables an independent palette of up to 256 colors for a solo frame. These files are compressed using a lossless data compression algorithm known as LZW( Lempel-Ziv-Welch) and this algorithm was created by Abraham Lempel, Jacob Ziv and Terry Welch. It removes the unwanted colours that are not in use to compress raster data. The maximum limit which is permitted for colours is 256 and the minimum is 2 (black and white). Apart from this, it has a fixed-length header which gives the version and pixel dimensions are provided by the ‘logical screen' descriptor. |
