Conversion from .CR2 or .NEF to .JPG completely removes EXIF

[Bonzo]

I do not think ImageMagick even finds the EXIF data in a CR2 image. If you use identify -verbose IMG_0792.CR2 there is no data displayed.

I thought you could save the data to a file and use jhead to write it back but I do not know if that would work.

Search for CR2 and you will find other posts about CR2 images and EXIF.

Does anybody knows how to convert Nikon raw (.NEF) to JPEG with PHP IMAGICK.
Each time i open .NEF with php imagick program read it as tiff with low resolution (width 160px).
Please help.

The NEF file contains a low-resolution JPG, and that is what Imagick (which isn't ImageMagick) is converting.

ImageMagick can convert the main image by using dcraw as a delegate. I just use dcraw directly.

Imagick is not a product of ImageMagick and not supported by Imagemagick. It has not been updated in quite a while and is missing many features of Imagemagick. If you really want to keep up and have more reliable results, then use PHP exec() command in place of Imagick. In general, you will not lose speed. See viewtopic.php?f=4&t=16779
