One very powerful feature is the Focus Points visualization while comparing images side by side. 0024 0025 Camera can use some points (name auto focus points) on image to make the region around sharper. Besides, it blurs the further region, in order to make an artistic product. These points are named AF points. They can be pre-defined by camera or by user, depend on model of camera. There are only two cases supported by digiKam for AF points: infocused and selected. Infocuses points are the points sharpened by camera, when selected points are the points expected to be clear by user. A point can be both in 2 cases (infocus-selected) or neither both (inactive). 0026 0027 .. figure:: images/light_table_comparing_focus_points.webp 0028 :alt: 0029 :align: center 0030 0031 The digiKam Light Table Comparing Focus Points From a Series Of Shots 0032 0033 Each point is not only a point on the image but a rectangle. Focus Point is used to recognize focus region of image. This is a region where image expected to be clear. Using the focus points visualization while previewing image side by side allows to be sure that the best image was taken with right in-focus shot conditions. 0034 0035 To Show the focus points over the preview canvas, select **Show Focus Points** from context menu. 0036 0037 .. figure:: images/light_table_preview_context_menu.webp 0038 :alt: 0039 :align: center 0040 0041 The digiKam Light Table Preview Canvas Context Menu 0042 0043 Comparing The Sidebars Contents 0044 ------------------------------- 0045 0046 One particularity on digiKam Light Table is the sidebar views available on the right and on the left sides. Both visualize provide the same contents as with **Main Window** right sidebar: 0047 0048 - :ref:`Properties <properties_view>`: File and image properties, key shooting parameters. 0049 0050 - :ref:`Metadata <metadata_view>`: Exif, Makernotes, IPTC, XMP, and ExifTool data. 0051 0052 - :ref:`Colors <colors_view>`: Histograms and embedded ICC profiles. 0053 0054 - :ref:`Maps <maps_view>`: View to show GPS location. 0055 0056 - :ref:`Captions <captions_view>`: Comments, Date & Time setting, Labels, Rating, Tags, selected metadata. 0057 0058 - :ref:`Versions <versions_view>`: Image history. 0059 0060 If both left and right sidebar are visible in Light Table, they can be used to compare images information loaded in left and right canvas preview. When you change the item on the right side, right sidebar contents will be updated. In opposite, left side contents will still the same. If both sidebar show the same tab view (as metadata for example), they can be used to compare visually the differences and select the best shot to mark in your workflow. 0061 0062 .. figure:: images/light_table_comparing_sidebars.webp 0063 :alt: 0064 :align: center 0065 0066 The digiKam Light Table Used To Compare Left And Right Metadata Contents 0067 0068 Asset Management In Light Table 0069 ------------------------------- 0070 0071 As with the **Main Window** **Preview** Mode, the left and right Light Table preview canvas propose the standard options from the context menu to apply the :ref:`digital asset management <organize_find>` with your images. 0072 0073 Faces Tagging 0074 ~~~~~~~~~~~~~ 0075 0076 To manage faces information, the options below are available: 0077 0078 - **Show Face Tags** to highlight face areas over the image. 0079 - **Scan For Faces** to start an automatic faces detection on image. 0080 - **Add a Face Tag** to add manually a face area over the image. 0081 0082 .. figure:: images/light_table_face_management.webp 0083 :alt: 0084 :align: center 0085 0086 The digiKam Light Table Editing A Face Tag From The Preview Canvas 0087 0088 The toolbar on top left corner of preview canvas provide also the same options to manage faces.

Of course this menu is available to the left and right pane. You can also use the **Caption** tab available on the left sidebar and on the right sidebar. More details about this tab is given in the :ref:`Caption View section <captions_view>` of this manual. 0094 0095 After assigning this kind of properties, you can found the marked items to the **Labels** and **Tags** tabs from the Main Window left sidebar.

Unlike Main Window, Light Table does not have the concept of albums or an icon-view where you can select items to process. Light Table has a thumbbar which is a flat list of items to review with the left and right panes. 0107 0108 For the tools working with pre-selected list of items from Main Window icon-view, the **View**, **Tools**, and **Export** menu options will use the current contents from the thumbbar. For tools working with albums, nothing change, as albums still selectable at tool sessions independently than thumbbar content. 0109 0110 The **Import** tools will simply append to the thumbbar the new contents. 0111 0112 .. figure:: images/light_table_post_processing.webp 0113 :alt: 0114 :align: center 0115 0116 The digiKam Light Table Running Print Creator Tool
