libptp is a Picture Transfer Protocol support library. It is used for downloading images from PTP cameras. It currently works with most modern cameras from the following vendor: Kodak, HP, Nikon, Canon, Panasonic, Olympus, Konica, Minolta, Fuji, Ricoh, and Sony. This package also contains "ptpcam", the tool used to tweak camera properties and perform some basic operations.
digiKam is an advanced digital photo management application that makes importing and organizing digital photos a trivial task. Photos can be organized in albums, which can be sorted chronologically, by directory layout, or by custom collections, and they can be tagged, commented, and rated. digiKam makes use of a fast and robust database to store meta-information, which makes adding and editing comments and tags very reliable. Metadata can also be stored inside pictures using Exif and IPTC. An embedded image editor and a standalone application named showfoto have simple but powerful features for editing your pictures with filters and correction tools.
exiftags parses a JPEG file looking for Exif (Exchangeable Image File) data, formatting, and printing image properties. Digital cameras typically add Exif data to the image files they produce containing information about the camera and digitized image. exiftags includes support for some camera manufacturer-specific properties.
JCap is a Java application for adding captions and descriptions to your digital photograph collection and includes a search dialog for finding photos later. It is completely self-contained; it doesn't require a separate database application or Web server to run. Captions, descriptions, and keywords are stored in plain text files in the same folder as the images they describe and can be read by any application that can read text files. The primary goals are: to help you find photos later, to help share photos with others, and to be able to read photo captions and descriptions thirty years from now on whatever computer you happen to have at the time.
Morena is a Java framework that allows a Java program to acquire an image from a scanner or camera. To communicate with the hardware, it uses standard interfaces: Twain for MS Windows and Mac OS X and Sane for a number of Unix platforms (AIX, BeOS, Darwin, FreeBSD, HP-UX, Linux, NetBSD, OpenBSD, OS2, Solaris, Unixware).
Exiv2 is a C++ library and a command line utility for managing image metadata. It provides fast and easy read and write access to the Exif, IPTC, and XMP metadata of images in many formats. The Exiv2 command line utility prints Exif, IPTC, and XMP metadata including Makernote tags in various formats, adjusts Exif timestamps, renames images according to the Exif timestamp, extracts and inserts Exif, IPTC, and XMP metadata and JPEG comments, or deletes the thumbnail or a specific type of metadata from an image.
pHoToMoLo is a toolset for managing JPEG images in JFIF or Exif format. Photomolo generates a static HTML 4.01- and CSS 1-based multi-resolution image gallery for a directory tree containing images. Exifiron losslessly compresses and corrects the orientation of Exif JPEG images. Jpegnail removes or embeds thumbnails. Jpegcom lets you edit embedded image comments using any text editor and image viewer. A shell script frontend for Exifiron is included for copying images from removable storage, such as USB or Compact Flash.
