The code exiftool -tagsfromfile %d%f.NEF -ext jpg -overwrite_original.But when I specify -quality 100 in ImageMagick the image sizes gain about 45 MB! Why? The images I converted using mogrify are slightly smaller (~ 1-2 MB) than those output by my colleague using picasa to convert NEF to JPG.Thanks in advance for any advice you have about how to do this. I've searched around quite a bit to try and find a solution to this and it seems like I may have to install ufraw, but if possible I'd like a solution that uses software I already have - ImageMagick and Exiftool. NEF files are successfully converted to JPGs, but all EXIF data are lost. I'm using the mogrify command because it handles batches nicely.Īll of my. I've just gotten started using ImageMagick from the command line.

Image files that employ JPG compression are commonly called 'JPG files' and are stored in variants of the JIF image format. The compression technique used is not processor-intensive, which was an advantage at the time of development due to hardware's relatively limited processing power in the 1980s.

PCX utilizes a lossless compression technique. A PCX file comprises three elements: the header, image data, and the 256 color palette. The PCX format was one of the first common bitmap image formats. JPG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography. However, certain scanning devices still output to the.

As a result, the file type is rarely used at present. It has since been superseded by other image formats such as png, gif, and jpeg. pcx file extension was developed in the 1980s by the ZSoft Corporation.
