5.5.5. Moving photographs among directories, hard disks or computers

+

After a photograph has been loaded into Subsurface and associated with a specific dive, the directory + where the photo lies is stored, allowing Subsurface to find the photograph when the dive is + opened again. If the photo or the whole photo collection is moved to another drive or to a different + machine, it is unlikely that the directory structure will remain identical to that of the original uploaded + photo. When this happens, Subsurface looks for the photos at their original location before they were moved, + cannot find them and therefore cannot display them. Because, after moving photos, large numbers of photos + may need to be deleted and re-imported from the new location, Subsurface has a mechanism that eases the + process of updating the directory information for each photo: automatic updates using fingerprints.

+

When a photo is loaded into Subsurface, a fingerprint for the image is calculated and stored with the + other reference information for that photo. After moving a photo collection (that has already been loaded + into Subsurface) to a different directory, disk or computer, Subsurface can perform the + following steps:

+
    +
  • +

    +look through a particular directory (and all its subdirectories recursively) + where photos have been moved + to, +

    +
    • +
  • +

    +calculate fingerprints for all photos in this directory, and +

    +
    • +
  • +

    +if there is a match between a calculated fingerprint and the one originally + calculated when a photo was + loaded into Subsurface (even if the original file name has changed), to + automatically update the directory information so that Subsurface can find + the photo in the new moved directory. +

    +
    • +
+

This is achieved by selecting from the Main Menu: File → Find moved images. This brings up a window within + which the NEW directory of the photos needs to be specified. Select the appropriate directory and click + the Scan button towards the bottom right of the panel. The process may require several minutes to + complete, after which subsurface will show the appropriate photographs when a particular dive is opened.

For instance, add +a space character at the end of the Notes text box and immediately delete +that space character. Select the optio Apply changes in the blue edit bar +to save the dive information.

    13.2.1. Recreational dives

    +

    The Subsurface dive planner allows a sophisticated way of planning +recreational dives, i.e. dives that remain within no-decompression limits. +The dive planner automatically takes into account the nitrogen load incurred +in previous dives. But conventional dive tables are also used in a way that +can take into account previous dives. Why use a dive planner for +recreational dives? Using recreational dive tables, the maximum depth of a +dive is taken into acount. However, few dives are undertaken at a constant +depth corresponding to the maximum depth (i.e. a "square" dive +profile). This means that dive tables overestimate the nitrogen load +incurred during previous dives. The Subsurface dive planner calculates +nitrogen load according to the real dive profiles of all uploaded previous +dives, in a similar way as dive computers calculate nitrogen load during a +dive. This mean that the diver gets credit in terms of nitrogen loading +for not remaining at maximum depth during previous dives, enabling planning +a longer subsequent dive. For the planner to work it is therefore crucial to +upload all previous dives onto Subsurface before performing dive planning.

    +

    To plan a dive, the appropriate settings need to be defined.

    +

    Ensure that the date and time is set to that of the intended dive. This +allows calculation of the nitrogen load incurred during previous dives.

    +
      +
    • +

      +Immediately under the heading Planning are two checkboxes Recreational + and Safety Stop. Check these two boxes. +

      +
      • +
    • +

      +Then define the cylinder size, the gas mixture (air or % oxygen) and the + starting cylinder pressure in the top left-hand section of the planner under + Available gases. +

      +
      • +
    • +

      +The planner calculates whether the specified cylinder contains enough + air/gas to complete the planned dive. In order for this to be realistic, + under Gas options, specify an appropriate surface air consumption (SAC) + rate for Bottom SAC. Suitable values are between 15 l/min and 30 l/min, + with novice divers or difficult dives requiring SAC rates closer to 30l/min. +

      +
      • +
    • +

      +Define the amount of gas that the cylinder must have at the end of the + bottom section of the dive just before ascent. A value of 50 bar is often + used. +

    The dive profile in the planner indicates the maximum dive time within +no-deco limits using the Bühlmann ZH-L16 algorithm and the gas and depth +settings specified as described above. The Subsurface planner allows rapid +assessment of dive duration as a function of dive depth, given the nitrogen +load incurred during previous dives. The dive plan includes estimates of the +amount of air/gas used, depending on the cylinder settings specified under +Available gases. If the initial cylinder pressure is set to 0, the dive +duration shown is the true no-deco limit (NDL) without taking into account +gas used during the dive. If the surface above the dive profile is RED it +means that recreational dive limits are exceeded and either the dive +duration or the dive depth needs to be reduced.

    Below is an image of a dive plan for a recreational dive at 30 +metres. Although the no-deco limit (NDL) is 23 minutes, the duration of the +dive is limited by the amount of air in the cylinder, reflected by the +information in the text box at the bottom right of the panel.

Initially, the GFHigh and GFLow values in the Preferences panel of Subsurface is used. If these are changed within the planner (see Gas Options within the planner), the new values are used without changing the original values in the Preferences. Gradient Factor settings strongly affect the calculated ceilings and their depths. @@ -4368,14 +4573,36 @@ information.
