NEF is an abbreviation of Nikon Electronic Format and is primarily used for retaining everything captured by a camera before it undergoes any form of processing. The information maintained by the NEF file format also includes metadata such as the camera name, lens type, and lens model. A file with the NEF extension is known as a Nikon RAW Image File, most commonly referred to as camera raw image files and used by Nikon digital SLR cameras, NEF files are digital negatives and contain information captured by the camera's image sensors. NEF files capture video in their original format without any form of in-camera processing of the hue, tone, sharpness and white balance.
The .ppm file extension is used for Portable PixMap format files and is intended to be an intermediate format that can be used in the development and conversion of other file formats. This format was specifically designed so that it could easily be exchanged between various platforms. It is very simple but not very storage efficient. Before the PPM format was introduced, Jef Poskanzer invented the PBM format in the year 1980 for transmission of monochrome bitmaps as ASCII text in email messages. He also developed a tool library for easy conversion of the PBM files to other graphical formats and vice versa. This library was called Pbmplus and was released in 1988. Later Poskanzer developed the PPM format along with the PGM format and the requisite tools that were added to Pbmplus.
FreeFileConvert uses tuned encoding for NEF to PPM conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload NEF files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized PPM results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent PPM audio with dependable progress tracking.
NEF files are used in Nikon digital cameras for capturing video without post-processing them or adding special effects. NEF files are stored as RAW image files and can be transferred to the computer for image editing and post-production purposes. NEF files can be converted to various other file formats such as TIFF, JPEG, PNG and can be used with image editing applications like Photoshop. NEF files are uncompressed, contain meta information of image data and are used for saving images taken with a Nikon digital camera. Any changes in the hue, tone and color made to the NEF files can be reversed, what this means is that users can fall back on any changes to the image they previously made through an image editing software and restore the image to its original quality.
A .ppm extension file comprises of two parts which include the header and the image related data. The header, in turn, is distributed into three parts that are demarcated by line feeds. The first line comprises of the magical PPM identifier which can either be P3 for the ASCII version or P6 for the binary version, and the next line has the image's height and width displayed in ASCII characters and the last line indicates the maximum color value of the pixels. The image data formatting is dependent on the magical identifier, given in the first line of the header. Each pixel consists of 3 decimal values ranging from 0 to the specified maximum value written in ASCII characters. The 0 in the decimal values denotes that the color is not present or is turned off and the maximum value denotes that the color is at its maximum level. Conventionally the image data is stored in a left to right and top to bottom order with each pixel being stored as a byte. The usual RGB (Red ñ Green ñ Blue) order is followed to store the components.
