<title>TIFF/EP</title>
<iso>TIFF/EP image data format ISO 12234:2001(E)</iso>
<description>The term TIFF/EP refers to Tag Image File Format/Electronic Photography, defined in this part of ISO 12234.
The term "TIFF 6.0" refers to the TIFF Revision 6.0 specification.
TIFF/EP is defined to be as compatible as possible with existing desktop software packages, to enable them to operate with images from electronic still-picture cameras.
TIFF Revision 6.0 is used as the basis for achieving this interoperability with the large installed base of imaging software.
Wherever possible, TIFF/EP uses tags already defined in TIFF 6.0 and provides guidelines for the use of these tags as well as the allowed field values.
New tags are defined to encode image data features that are not included in TIFF 6.0. These new tags conform to the practices specified in TIFF 6.0.
This document also describes how related images, such as both "parent" high resolution and "thumbnail" low resolution images of the same subject, or temporal sequence "bursts" of the same scene, can be stored in a single TIFF/EP file.</description>

Another application of this interlace mechanism is to store images for progressive transmission.

For 2-dimensional interlace, the 7 least significant bits of the value indicate the vertical field number, and the next 7 bits indicate the horizontal field number. To store multiple interlace fields in one TIFF/EP file, the different fields shall use the IFD chaining mechanism.
