The FoCal Settings page is organised as a set of collapsible panels. Click the arrow (^) on the right side of the title bar to collapse or expand a panel.
These options specify whether a message is shown under the following situations:
If the options are not ticked, you will not be told about these situations.
By default, this option is enabled and distance information will be shown in metres.
If you untick this option, distances will be shown in feet and inches.
With this option enabled, FoCal to warn you of any situations that may affect the quality of your results – for example having a battery grip connected to your camera, or not having the eye-piece covered on DSLR cameras.
For experienced users, these messages may be repetitive so you can disable them with this option but it is generally not recommended to disable them.
Some messages can be “dismissed” so they don’t show again – this is actioned by ticking the Don’t show again button on the bottom of the message boxes.
If you hit the Restore Messages button you will be shown all messages again (but still have the option to dismiss any individual messages in future).
When you run a test, your results can be uploaded to Reikan. This allows us to create the FoCal Comparison Database so we can share the typical behaviour of camera and lenses back through FoCal, so you can compare your results with all other FoCal users with the same equipment.
Note that FoCal never uploads images taken by your camera – the uploaded results are simply the numerical results values from various parts of the tests and some metadata associated with the camera/lens settings.
For more information please see: Upload Results to Reikan
When running tests, FoCal will store the image crops on your computer so when you review images from the history you can see the actual images that were taken. The default size allocated for these images is 1000MB – when this limit is exceeded, the oldest images are removed.
The current amount of storage space taken by the crop images is shown by the Current Cache Size information entry.
Hitting this button will restore FoCal settings back to how they would be with a new, clean install of the software. If you are having issues with FoCal, it can be useful to restore the settings using this option.
It is sometimes useful to increase or decrease the size of the text, buttons etc in the FoCal user interface – when running on small-screen computers for instance.
The default setting is 100%, but you can make the elements of the user interface smaller or larger by adjusting this setting.
