Managing digital photographs in Linux is very straightforward. KDE's
digiKam downloads your images directly from your camera. It helps you
organize and manipulate your images to get the best possible results. The
application includes several useful plug-ins that can convert your images
to various different formats. Image improvement plug-ins also include red
eye reduction, speck removal and hot pixel removal. Various filter and
effect plug-ins help create little works of art from your digital images.

Start digiKam from the main menu or by pressing <span class="keycap">Alt</span>+<span class="keycap">F2</span> and entering
<span class="command"><strong>digikam</strong></span>. digiKam will ask you to choose a location to
store your images and albums. On start-up, digiKam shows a window with
two main areas: a list of your albums to the left and the images in the
current album to the right. See
<a class="xref" href="cha.digicam.html#fig.digikam.mainwin" title="Figure 17.1. The Main Window of digiKam">Figure 17.1, “The Main Window of digiKam”</a>. The far right edge of the
window has a number of tabs attached which can be used to display
important information about your images, or to manipulate certain
image-related data:
</p><div class="variablelist"><dl><dt><span class="term"><span class="guimenu">Properties</span>
</span></dt><dd><p>
Use this tab to access properties assigned to your images, such as
file properties (permissions, ownership, modification date, etc.),
image properties (dimensions, file format, etc.), and photograph
properties (basic model, exposure and aperture information).
</p></dd><dt><span class="term"><span class="guimenu">Metadata</span>
</span></dt><dd><p>
Use this tab to access the various kinds of metadata associated with
your images, such as EXIF and GPS.
</p></dd><dt><span class="term"><span class="guimenu">Colors</span>
</span></dt><dd><p>
Use this tab to access color management-related data and to analyze
the histograms associated with your images.

To download images from your digital camera, simply connect the camera to
the USB port of your computer using the USB cable provided by the camera
manufacturer. Depending on your camera model, you may need to switch your
camera to a special data transfer mode. Consult the camera's manual about
this.
</p><p>
There are four possibilities for accessing the pictures on the camera:
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li><p title="USB Mass Devices"><b>USB Mass Devices. </b>
If your camera can be switched to a USB mass storage device, select
this option. After you connect the camera to the USB port of your
computer and turn the camera on, the new USB device is automatically
detected and mounted. KDE lets you select the action to take in the
event of any such device being mounted. You can choose to start
digiKam or any other image viewing or processing application whenever
a device of this type is mounted.
</p></li><li><p title="PTP (Picture Transfer Protocol, also Known as PictBridge)"><b>PTP (Picture Transfer Protocol, also Known as PictBridge). </b>
If your camera can be switched to PTP, select this option. Normally
your camera is not automatically mounted in PTP mode, but can be
accessed through digiKam.
</p></li><li><p title="Special Drivers and Gphoto2"><b>Special Drivers and Gphoto2. </b>
If your camera supports neither USB mass storage nor PTP, try the
special drivers provided by gphoto2, see
<a class="xref" href="cha.digicam.html#sec.digicam.trouble" title="17.12. Troubleshooting">Section 17.12, “Troubleshooting”</a>
</p></li><li><p title="Card Readers"><b>Card Readers. </b>
Nowadays cameras can use different non-volatile memory cards. For
example, SD memory cards, compact flash (CF), memory sticks, to name a
few. Some new computers have a card reader on board with different
slots, to support all these formats. If you do not want to deal with
cables, protocols, or drivers, select this option, as it simplifies a
lot. Normally, card readers are detected as removable devices and are
automatically mounted in KDE.
</p></li></ol></div><p>
To set up a camera in digiKam, select <span class="guimenu">Import</span>+<span class="guimenu">Camera</span>+<span class="guimenu">Add
Camera</span>. First, try to detect the camera
automatically with <span class="guimenu">Auto-Detect</span>. If this fails, browse
the list of supported cameras for your model with <span class="guimenu">Add</span>.
If your camera model is not included in the list, try an older model or
use USB/IEEE mass storage camera and confirm with <span class="guimenu">OK</span>.

To download images from a camera that has been properly configured,
attach the camera to your computer and select the camera from the
<span class="guimenu">Camera</span> menu. digiKam opens a window and begins to
download thumbnails and display them as in
<a class="xref" href="cha.digicam.html#fig.digikam.picdownload" title="Figure 17.2. Downloading Pictures from a Camera">Figure 17.2, “Downloading Pictures from a Camera”</a>. Right-click an image to
open a pop-up menu with the options to <span class="guimenu">View</span> the image,
to <span class="guimenu">Download</span>, or <span class="guimenu">Delete</span> the image.
Select the <span class="guimenu">Settings</span> tab to the right of the download
window to rename the image files using <span class="guimenu">Renaming

Select all images to download from the camera by pressing the left mouse
button or by clicking individual images with
<span class="keycap">Ctrl</span> pressed, or by using one of the
select modes provided by the <span class="guimenu">Images</span> menu at the bottom
of the download window. Click <span class="guimenu">Download</span> and select the
destination from the list, or create a new album with <span class="guimenu">New

To save your camera's battery power, you can also attach a USB hub to
your computer (providing an appropriate slot for your storage medium)
and download the files from there. Once the USB hub is connected to your
computer, the KDE media handler dialog opens and offers to download the
images from the medium you attached.

By default, digiKam creates a folder called <span class="guimenu">My Albums</span>
to hold all root albums, called collections. Collections can store
albums, while albums store sub albums and images. The first collection
was created on first start with the First-run Wizard dialogue.
</p><p>
The albums can be sorted by directory layout, by collection name set in
the album properties, or by the date that the albums were first created
(this date can also be changed in the properties of each album).
</p><p>
To create a new album, use one of these methods:
</p><div class="itemizedlist"><ul class="itemizedlist" type="bullet"><li class="listitem" style="list-style-type: disc"><p>
Upload new images from the camera and create the target album during
the download.
</p></li><li class="listitem" style="list-style-type: disc"><p>
Create a new album by selecting a collection folder first and then
<span class="guimenu">Album</span>+<span class="guimenu">New Album</span> from the main menu or via right-click.
</p></li><li class="listitem" style="list-style-type: disc"><p>
Import an existing folder of images from your hard disk (select
<span class="guimenu">Import</span>+<span class="guimenu">Add
Folders...</span>).
</p></li><li class="listitem" style="list-style-type: disc"><p>
Right-click a collection folder and select <span class="guimenu">New
Album</span>.
</p></li></ul></div><p>
To create a new collection, go to <span class="guimenu">Settings</span>+<span class="guimenu">Configure
digiKam</span>, <span class="guimenu">Collections </span> menu and
choose <span class="guimenu">Add Collection</span>.
</p><p>
Once you have chosen to create a new album, provide some basic
administrative information about the new album, such as an album title.
Optionally, choose a category, insert some comments, and select an album
date. Categories are a way of organizing your albums by a common label.
This label is used when you select <span class="guimenu">View</span>+<span class="guimenu">Sort Albums</span>+<span class="guimenu">By Category</span>. The comment is shown in the banner at the top of the main
window. The album date is used when you select <span class="guimenu">View</span>+<span class="guimenu">Sort Albums</span>+<span class="guimenu">By
Date</span>.
</p><p>
digiKam uses the first photograph in the album as the preview icon in the
<span class="guimenu">My Albums</span> list. To select a different one, right-click
the respective photograph and select <span class="guimenu">Set as Album
Thumbnail</span> from the context menu.
</p></div><div class="sect1" title="17.5. Managing Tags"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="sec.digikam.tags"></a>17.5. Managing Tags<span class="permalink"><a alt="Permalink" title="Copy Permalink" href="#sec.digikam.tags">¶</a></span></h2></div></div></div><p>
Managing a high number of different images across various albums can be
very difficult. To manage your images by custom categories and across
albums, digiKam provides the <span class="guimenu">My Tags</span> system. Tags
categorize images, and more than one tag can be assigned to an image.
</p><p>
For example, assume that you took several pictures of animals and
distributed them across various albums. Now you are looking for an easy
way to generate an overview of all pictures ever taken of animals. Using
digiKam's tags, proceed as follows for this scenario:
</p><div class="procedure"><ol class="procedure" type="1"><li><p>
Select <span class="guimenu">Tag</span>+<span class="guimenu">New Tag</span> in the upper menu bar and enter a name for the new tag,
in this case <code class="literal">animals</code>.
</p><p>
The dialog box allows you to create hierarchical tags, too. For
example, to have a <code class="literal">bear</code> tag which is underneath a
<code class="literal">animals</code> tag, insert <code class="literal">animals/bear</code>
into the text field. Provide an optional icon and leave this dialog
with <span class="guimenu">OK</span>.
</p></li><li><p>
Go to each album and tag all images showing some animals by
right-clicking the image and selecting <span class="guimenu">Assign
Tag</span>+<span class="guimenu">animals</span>+<span class="guimenu">Assign this
Tag</span>. To tag more then one picture at once, use
the <span class="keycap">Ctrl</span> key.
</p></li></ol></div><p>
If you need to process a huge number of images, an easier way to do the
tagging would be using the <span class="guimenu">Captions/Tags</span> tab from the
tab bar at the right edge of the main window. This interface allows you
to assign tags to this image, enter an optional descriptive comment, and
rate this image. When you are done with the first image, stay in this
dialog, click the right arrow button, and click <span class="guimenu">Apply</span>
when finished to apply your settings. Do it with all your images of this
album. Proceed similarly with all other albums and images.
</p><p>
To retrieve all images in your entire collection that carry a certain tag
(in this case <code class="literal">animals</code>), proceed as follows:
</p><div class="procedure"><ol class="procedure" type="1"><li><p>
Open the <span class="guimenu">Tags</span> tab in the left tab bar.
</p></li><li><p>
Unfold the <span class="guimenu">My Tag</span> item.
</p></li><li><p>
Select the <span class="guimenu">animals</span> tag.
</p><p>
As a result, all images in your entire collection carrying this tag are
displayed.
</p></li></ol></div><div class="figure"><a name="fig.digikam.tabs"></a><p class="title"><b>Figure 17.3.

Any image collection soon becomes unmanageable if you do not find a means
to easily search for the images you need and find them. To help you
organize your collection, digiKam offers you two search options:
</p><div class="variablelist"><dl><dt><span class="term">Simple Search</span></dt><dd><p>
A basic search. Select <span class="guimenu">Tools</span>+<span class="guimenu">Search</span> and enter a text string that

hit <span class="guimenu">OK</span>. You can save this search for future use,
and edit other existing searches listed under
<span class="guimenu">Searches</span> on the left edge of your digiKam window.
</p></dd><dt><span class="term">Advanced Search</span></dt><dd><p>
Complex search filter. Select <span class="guimenu">Tools</span>+<span class="guimenu">Advanced Search</span>, provides a wide

The editing mode contains more useful features. Use the
<span class="guimenu">Decorate</span> menu to superimpose various kinds of
graphics and text effects onto your images without having to bother
about filters and their fine-tuning:
</p><div class="variablelist"><dl><dt><span class="term"><span class="guimenu">Apply Texture</span>
</span></dt><dd><p>
Select the type of texture you want to apply to your image and
determine how prominent this texture should be
(<span class="guimenu">Relief</span>). digiKam applies the texture and saves
the changes to the original copy of your image.
</p></dd><dt><span class="term"><span class="guimenu">Add Border</span>
</span></dt><dd><p>
Select the type of border. Depending on the type of border you have
selected, choose one or two colors to be used for the border and set
the width of the border around your image. digiKam creates the border
and saves the changes to the original copy of your image.
</p></dd><dt><span class="term"><span class="guimenu">Insert Text</span>
</span></dt><dd><p>
Enter the text you want to superimpose on the image. Choose font,
font style and size. Select the text justification and decide whether
the text should be rotated (and to what degree). Add an optional
border and semi-transparency. digiKam adds your text layer to the
original image.
</p></dd><dt><span class="term"><span class="guimenu">Template Superimpose</span>
</span></dt><dd><p>
Just as you can superimpose any text on your image, you can also
apply ready-made templates to create funny greeting cards, posters
and the like.

Manipulating Color Settings<span class="permalink"><a alt="Permalink" title="Copy Permalink" href="#sec.digikam.color">¶</a></span></h3></div></div></div><p>
The <span class="guimenu">Color</span> menu allows you to manage all kinds of
different color-related settings. Its capabilities range from simple
auto correction mechanisms to full-blown color management via color
profiles:
</p><div class="variablelist"><dl><dt><span class="term">Auto Color Correction</span></dt><dd><p>
If aiming for a straightforward color and exposure correction of your
image, try this option. Choose from various preset modes and apply
the one that matches best. Use the histograms to determine whether
the result matches your needs.
</p></dd><dt><span class="term">Brightness/Contrast/Gamma</span></dt><dd><p>
This tool offers a simple way of fixing over or underexposed images.
</p></dd><dt><span class="term">Hue/Saturation/Lightness</span></dt><dd><p>
This tool helps you to optimize images that have been taken under
very bright lighting conditions and appear somewhat washed out. Bring
color saturation back to these images by manipulating the hue and
saturation sliders. Depending on the level of color, you might also
want to adjust the lightness to prevent the image from registering
too dark. Of course, you can also use this tool to achieve the
opposite effect if you need to brighten up an image that has been
taken at low light conditions and contains far too much color
saturation.
</p></dd><dt><span class="term">Color Balance</span></dt><dd><p>
Depending on the lighting conditions under which an image was taken
or the quality of an image scan, the colors may appear somehow out of
balance. Using the color balance tool, you can try to shift the
balance towards another end of the color spectrum.
</p></dd><dt><span class="term">Invert</span></dt><dd><p>
Invert the color values.
</p></dd><dt><span class="term">Black & White</span></dt><dd><p>
Transform your color image into black and white. Use the
<span class="guimenu">Film</span>, <span class="guimenu">Lens Filters</span>,
<span class="guimenu">Tone</span>, and <span class="guimenu">Lightness</span> to tweak
the end product. The <span class="guimenu">Film</span> tab offers you to
emulate the effects various black and white films. To emulate color
filters used with the camera lens, use the <span class="guimenu">Lens
Filters</span> tab. Note that you can only apply one filter at a
time. Using the <span class="guimenu">Tone</span> tab you can have your black
and white image tinted in a particular way (sepia, for example).
</p></dd><dt><span class="term">Depth</span></dt><dd><p>
Determine the color depth (in bits). Transform 8-bit into 16-bit
images and vice versa.
</p></dd><dt><span class="term">Color Management</span></dt><dd><p>
Color management via ICC color profiles helps you maintain color
fidelity across multiple output devices (camera, display, printer).
</p></dd><dt><span class="term">Levels Adjust</span></dt><dd><p>
Use this option to control multiple levels and to check the resulting
image in just one tool. It lets you save the chosen level settings
and thus enables you to apply the same corrections to multiple
images, if needed. This comes in handy if you know that your camera
tends to use the same faulty color settings all the time, and you
would like to be able to correct them with just a single click.
</p></dd><dt><span class="term">Color Effects</span></dt><dd><p>
This tool offers a selection of color effects like edge finding,
solarizing, etc.
</p></dd><dt><span class="term">White Balance</span></dt><dd><p>
Every source of light registers differently on your digital camera's
chip. Depending on the light source, the color temperature tends to
register either warmer (towards the red end of the spectrum) or
cooler (towards the blue end of the spectrum) than standard daylight.
Most cameras ship with preset white balance schemes that try to
compensate these effects. If the resulting images registers faulty,
use the white balance adjustment provided by digiKam. Either
manipulate the color temperature directly by using the Kelvin slider,
or choose one of the preset white balance schemes.
</p></dd><dt><span class="term">Curves Adjust</span></dt><dd><p>
This tool allows you to basically perform any operation available
through the <span class="guimenu">Brightness/Contrast/Gamma</span> and the
<span class="guimenu">Levels Adjust</span> tools, but in one tool and using
free-function mapping. Therefore this tool is more powerful and
flexible than the other two, but it may take some time to get used
to.
</p></dd><dt><span class="term">Channel Mixer</span></dt><dd><p>
The channel mixer tool provides an alternative way of converting
colored images to black and white. Using the
<span class="guimenu">Monochrome</span> option and the channel sliders, you can
selectively determine how much each of the color channels contributes
to the overall image. The channel mixer option is much more flexible
than the standard conversion to black and white, because you can
manage each color channel separately.

</p><div class="variablelist"><dl><dt><span class="term"><span class="guimenu">Find Duplicate Images</span>
</span></dt><dd><p>
If you suspect that your collection contains a number of duplicates,
use this option to find and delete them. First, determine which album
or tag to include in the scope of your search. Click
<span class="guimenu">OK</span> to initiate the search. If your collection
contains any duplicates, you get a split screen showing both images
and can select one of them for deletion.
</p></dd><dt><span class="term"><span class="guimenu">Create Calendar</span>
</span></dt><dd><p>
Create a simple calendar using a standard layout by selecting the
images to use and by selecting paper size and fonts.

If you need to perform certain actions on a large number of files at
once, use batch processing. Add borders, edit colors, apply various
effects and filters, rename and resize images, recompress them, or
perform a RAW conversion.
</p><p>
To find out whether your camera's RAW format is supported by the digiKam
converter plug-in, check <span class="guimenu">Help</span>+<span class="guimenu">Supported RAW Cameras</span>. Use
<span class="guimenu">Batch</span>+<span class="guimenu">Convert
Images</span> to convert images from one format to
another, for example from jpg to png.
</p><p>
An example of batch processing of images could involve applying a
solarizing effect to a number of images. To queue images for batch
processing and perform the actual processing, proceed as follows:
</p><div class="procedure"><ol class="procedure" type="1"><li><p>
Select <span class="guimenu">Batch</span>+<span class="guimenu">Image
Effects</span> or right-click the album's name and
select <span class="guimenu">Batch Processes</span>+<span class="guimenu">Image
Effects</span>.
</p></li><li><p>
Set the effect to <span class="guimenu">Solarize</span> and click
<span class="guimenu">Options</span> to determine the degree of the effect to be
applied and display an optional preview.
</p></li><li><p>
Decide whether to rename or overwrite the original images, or even have
them removed after the transformation has taken place.
</p></li><li><p>
Set the target folder to hold the resulting images. If you do not want
the new images to be written to the original folder, select
<span class="guimenu">New</span> and add a new folder or subfolder. Select the
new folder with your mouse pointer.
</p></li><li><p>
Accept or modify the list of images queued for the transformation.
</p></li><li><p>
Click <span class="guimenu">Start</span> to initiate the transformation.
</p><p>
digiKam informs you about the progress and the success of the
transformation.

Although openSUSE and digiKam support a broad range of cameras, you
might occasionally hit one of the following problems when using your
digital camera with openSUSE:
</p><div class="variablelist"><dl><dt><span class="term">Downloading Images from Your Camera Fails</span></dt><dd><p>
<a class="indexterm" name="id547122"></a>
If downloading your images fails no matter which protocol you have
chosen (PTP or USB), try using the command line instead of digiKam.
The <span class="command"><strong>gphoto2 <code class="option">--P</code></strong></span> command
initializes the camera and downloads the images if gphoto2 supports
this camera.
</p></dd><dt><span class="term">Your Camera is not Officially Supported by digiKam</span></dt><dd><p>
Try <span class="command"><strong>gphoto2 <code class="option">--list-cameras</code></strong></span> and the
information at <a class="ulink" href="http://www.gphoto.org/" target="_top">http://www.gphoto.org/</a> to obtain more
information about the status of your camera's support by Linux.
</p><p>
If the camera is not listed there, remove the storage medium from the
camera and use a card reader device (either an external or internal
one). As soon as the medium is detected, it is mounted automatically
and you can import the images to your digiKam collection with
<span class="guimenu">Import</span>+<span class="guimenu">Add Images</span> or <span class="guimenu">Import</span>+<span class="guimenu">Add
Folders</span>.
