[Nhcoll-l] Raw file format

[Dawn Roberts]

Hi Paul,

 

Your master preservation files for images created with digital cameras
should be saved as DNGs. Proprietary file types, such as the RAW files
created by Canon or Nikon cameras, etc are not universally accessible,
so have a high potential of creating problems for access down the road.
Convert the RAW file format to DNG within a program such as Photoshop;
DNG files are large as they retain the maximum pixel data for your
image. Make sure you're adding metadata to your DNG files. Then you can
create derivatives for use, e.g. high resolution TIFF files, low-res
JPEGs, etc.

Folks,

 

A question for those of you running imaging projects: in what format do
you store the original, high-resolution files? We have been using Nikon
raw (.nef) but as Adobe no longer makes plug-ins for the latest versions
we are contemplating converting to DNG before storing the images. 

 

Regards,
