It is great for graphics and visuals with animation. Have you seen moving images (not videos) in the web? Most of these files use the GIF format. In addition, you can’t display images on the Internet using this format. Ī TIFF file, similar to a RAW file, is extremely large. TIFF is also supported by various photo editing applications such as Photoshop, Lightroom, Illustrator, Photomatix, Google Nik, and more. It is also a favorite of printers because there is no loss in quality when the image is printed. The information is retained in layers, which depends on how you save the file. TIFF is a lossless file format which is popular among graphic artists, photographers, and publishers. Finally, since any alteration is written directly into the DNG file, you have to back up the entire file each time a change is made. The format also removes unrecognized metadata from RAW files, making it virtually impossible to retrieve such data from DNG files in the future. However, it takes a long time to convert RAW files into DNG. Also, enhancements, new features, and extra functionalities are assured since Adobe continuously works on the DNG format. The DNG format has checksum information that is used to scan and prevent file corruption. In fact, DNG files are 15 to 20 percent smaller in size than RAW files without any loss of quality.

Thus, even if it is created by Adobe for its applications, any software that can read or convert DNG format can be used.Ĭonverting RAW files to DNG is highly recommended as this will significantly decrease the size of the images, making them easy to download, upload, or send via email. However, unlike RAW that uses specific formats based on camera types or manufacturers, DNG stores image data in a compatible, generic format. DNG (Digital Negative)ĭNG is a lossless format similar to RAW. However, they usually save the final result in a more compressed format (most likely JPEG). Many photographers, editors, and graphic artists use RAW images during the editing phase. However, this drawback has been mitigated by using open-source computer programs such as dcraw. As such, specialized software may be needed to open RAW files. Also, there is no widespread adoption of a standard RAW format. Obviously, fewer images can be saved in your memory card or hard drive due to the massive amount of data in the RAW file. Only the metadata that controls the rendering is altered, but the original file data remains untouched.
In addition, changes made to RAW files are non-destructive. They show more shades of colors and better representation of white balance, contrast, exposure etc. Because they are lossless, the images are extremely high-quality. RAW files are processed directly from the camera’s sensor, thus they do not use compression. But that also means lossless files takes a lot of space in your storage device. On the other hand, a lossless algorithm retains all the information in the image. Lossy files can be saved in your computer at various quality levels. However, the loss of information lowers the overall quality of the image. Before discussing the image file types that photographers commonly use, it is important to know the concept of lossy and lossless file compression.Ī lossy algorithm removes some information in the digital file to reduce the file size.
