   <title>Workflows with &kphotoalbum;</title>
   <para>Workflow is rather important aspect in digital imaging. In this
   chapter we describe different workflows that fit on different needs.
   There are many different factors that must be considered when
   developing a workflow. Hopefully these examples will provide you with
   sufficient ideas of how to tune-up your own method of working with
   digital imaging.</para>
 
   <sect1 id="raw-workflow">
   <title>RAW workflow using &kphotoalbum; and Bibble5/AfterShot Pro</title>
   <para>When shooting RAW images the files from camera must be developed
   to commonly recognized format like JPEG or TIFF. There are a few
   options to choose from when working on Linux. For example RawTherapee
   and Ufraw are open-source alternatives when Bibble5/AfterShot Pro are
   commercial application for this purpose.</para>
 
   <para>A few settings are recommended for a RAW workflow.
   First is to enable the using of the embedded thumbnail. This will give
   a tremendous speed boost over decoding each raw file each time they are
   viewed (check also the minimum dimension configuration to ensure decent
   quality). Second one is for the New Image Finder to automatically stack the
   developed versions over the RAW file (developed image must be on same
   directory as the original). This requires regular expressions as
   described in <xref linkend="opt-search-new" />. Two helper scripts are
   provided in &kphotoalbum; sources to help in RAW workflow. These are
   open-raw.desktop and open-raw.pl. The first one enables GUI applications to
   open the RAW files in the open-raw.pl script that tries to find the original
   RAW file and open that instead of the developed image.
   </para>

     <title>Sending Images to RAW Editor</title>
     <mediaobject>
       <imageobject>
         <imagedata fileref="raw-external.png" format="PNG"/>
         </imageobject>
       </mediaobject>
   </figure>
 
   <para>First step in actual workflow is to copy the images from camera to the
   computer. A simple copy on a terminal window is all that is needed:
   </para>
   <screen><userinput><command>cp</command> <option>-a</option> <filename>/media/.../101CANON/</filename> <filename>~/Pictures/2012/sample</filename>
   </userinput></screen>
   <para>
   Then either start &kphotoalbum; or run
   <menuchoice><guimenu>Maintenance</guimenu><guimenuitem>Rescan for
   Images and Videos</guimenuitem></menuchoice>. New images should be
   found and now is time for initially tagging the images. As I usually photograph while
   traveling I first insert the place. Select <guilabel>Folder</guilabel>
   and browse to the new directory. Then go to the
   <guilabel>Show Thumbnails</guilabel>, select all
   and <guimenu>Annotate Multiple Items at a Time</guimenu> or <keycombo
   action="simul">&Ctrl;<keycap>2</keycap></keycombo>. Insert the
   proper place like Finland-Helsinki (see <xref
   linkend="sec-member-groups-in-property-editor"/>).
   </para>
 
   <para>Now that the new images are easy to find I do the
   initial ranking and deletion. For this I go to the thumbnail
   view and start the Viewer by hitting &Enter;. I use
   rating for good images, just press the appropriate number from
   <keycap>1</keycap> to <keycap>5</keycap>. I only give 3 to 5 ratings
   and hit <keycombo
   action="simul">&Ctrl;<keycap>Del</keycap></keycombo>
   for the bad photos to delete them. At this point I might add also
   People names if there happens to be a diver in the photo. Once the
   first round is done I exit the Viewer by hitting &Esc;
   and select <guimenuitem>Delete file from disk</guimenuitem> to get rid off the
   bad images for good.
   </para>
 
   <para>Next I select only the images that have high enough rating using
   the search function. Naturally the Place has to be set if search is
   started with <keycombo
   action="simul">&Ctrl;<keycap>F</keycap></keycombo>.
   However, if search is invoked from the Main Window the current
   selection is drilled down to the more precise match. Anyway, at this
   point I go through the better rated images again doing refining on the
   rating. E.g. if I have 5 similar photos of one Nudibranch species I
   generally decrease the rating of the poorer images and might increase
   the best one. Comparing images can be done by selecting the ones you
   want to compare and starting the Viewer. Removing images from the
   Viewer selection can be done with <keycap>Delete</keycap>. This only
   disables the viewing of the current image while within the Viewer,
   nothing is removed or deleted. This allows comparing 2 or 3 better
   images next to each other moving between them with
   <keycap>PgUp</keycap> and <keycap>PgDn</keycap>. I quite commonly use
   a <literal>tmp</literal> category to mark &eg; crabs and shrimps to be
   easily able to display only selected type of images during the later
   phases of selection and identification.</para>
 
   <para>After a reduced amount of images is left I start tagging them. I
   add the Latin Name of the species and Common Name. Whenever I have
   these two categories completed I consider the image Done and get rid
   of the Untagged marking. Note that if you still need to do tagging
   after developing the RAW image (and auto-stacking them) you need to
   select the top of collapsed stack (or all images on expanded stack)
   and select <emphasis>Annotate Multiple Items at a Time</emphasis> to
   get the whole stack annotated instead of only the topmost
   image.</para>
 
   <para>The best images are sent to external application for developing.
   With wanted images selected, right click on selected thumbnail and
   select <menuchoice><guimenuitem>Invoke External
   Program</guimenuitem><guimenuitem>All Selected
   Images</guimenuitem><guimenuitem>Send
   Bibble5</guimenuitem></menuchoice>. The application
   selected is actually my script that detects if there is a RAW file for
   the possibly already developed images available and uses that if possible.
   Within the external application I do some tuning up and cropping if
   required and then output the developed JPEGs next to the original RAW file.
   File naming is rather simple, change the extension or add underscore
   and running number if needed.
   </para>
 
   <para>Now that there is plenty of new JPEGs in the image directories I
   let &kphotoalbum; search for new images and automatically stack the
   new ones on top of the original RAW (<xref linkend="fig-options-file-versions" />).
   Then a final round of selection with the developed images and adding some
   descriptions if needed.</para>
 
   <para>Final step is to generate static &HTML; pages and upload to my web
   server for the enjoyment of friends and colleagues. This I do with the
   stacks collapsed to only get the developed images to the web page.
   &HTML; generation is described in <xref
   linkend="chp-generating-html"/>.</para>

   <sect1 id="pano-workflow">
   <title>Panorama workflow</title>
   <para>
   Panoramas require a bit different workflow than normal photo editing.
   This is due to the requirement for multiple source files. The tool of
   choice for panoramas is Autopano Pro but latest version of &digikam;
   should do well and fits zero budget. Following list describes the
   steps required:
   <orderedlist>
   <listitem><para>Tag the photos belonging to a panorama in
   &kphotoalbum; appropriately. This is done mainly to avoid discarding
   images by accident, when sorting out the garbage among the photos
   taken. You probably want also to stack the set of source images at
   this point.</para></listitem>
   <listitem><para>You have at least two simple options for next
   step:
   <orderedlist>
   <listitem><para>You can let Autopano Pro find the panoramas
   automatically from the photo directory.
   </para></listitem>
   <listitem><para>Or send the proper images to Autopano Pro on command
   line to speed things up. This is handy if the image directory contains a
   lot of images, especially RAW ones.  This requires one to fix the script
   that starts Autopano Pro to accept input and to create a desktop file or
   invoking external program with own command line.</para></listitem>
   </orderedlist>
   </para></listitem>
   <listitem><para>If it happens that the resulting panorama is missing a
   small part, you can try to craft it e.g. with the Gimp. Gimp works
   usually quite well if there is enough "structure" to be cloned but there
   is absolutely no guarantee you will get usable
   results.</para></listitem>
   <listitem><para>Save the new image somewhere under &kphotoalbum;'s image
   directory and run
   <menuchoice><guimenu>Maintenance</guimenu><guimenuitem>Rescan for Images
   and Videos</guimenuitem></menuchoice>. This should notice the new
   panorama and include it in the picture gallery.
   </para></listitem>
   <listitem><para>If you have set the AutoStacking of new images properly
   and name of the new panorama matches the rules for this, the panorama
   should be on top of the stack. Otherwise sort the images by date, so the
   new panorama ends up at by the source images and stack them manually.
   (Autopano Pro seems to write the EXIF info of the first image into the
    panorama.)</para></listitem>
   <listitem><para>You can still add tagging at this point to the panorama
   or you might include all the source images also with
   <keycombo>&Ctrl;<keycap>2</keycap></keycombo>.</para></listitem>
   </orderedlist>
   </para>
