What is the difference between NEF and CR2 files? Which one is better and why?

 NEF and CR2 are both file formats used for digital images. NEF stands for Nikon Electronic Format, and it is the proprietary raw image format used by Nikon cameras. CR2 stands for Canon Raw Version 2, and it is the proprietary raw image format used by Canon cameras.

In general, raw image formats like NEF and CR2 contain the unprocessed data from the camera's image sensor, allowing for more flexibility and control in post-processing. They are generally considered to be of higher quality than JPEGs, which are a processed image format.

As for which one is "better", it depends on the camera and the specific use case. Both NEF and CR2 files are high-quality, but they are specific to their respective camera brands. If you are using a Nikon camera, you will want to use NEF files, and if you are using a Canon camera, you will want to use CR2 files. It's also worth noting that different software support different files, so make sure to check the software you are using to edit your images
