The Prefs tab contains some options for defining the behavior of B/W Styler.
On Start Up
The default On Start Up control is "Previous Settings". This option will load the settings that were previously applied to an image with B/W Styler. The "Default Settings" option will set all controls back to default values, which deactivates all effects but still applies a basic B/W conversion. The "Logged Settings" option will automatically open the settings that were applied the last time to the same image. It only works if you previously had the Log Settings check box activated and if you use Photoshop or Paint Shop Pro (see below for more information).
The behavior of the Reset button can be defined by the On Reset combo box. If it is set to "Default Settings" and you click the Reset button, most controls will be deactivated.
If On Reset is set to "Previous
Settings", clicking Reset will load the settings that were used for correcting
the previous image. If you select "Own Defaults", you will be prompted
to select an existing preset file. So, if you want the Reset button to revert
all controls back to your preferred settings, you must first save these settings
to a preset file. See below the following page
for more information about saving preset files.
If you press the Reset button after setting On Reset to "Logged Settings", B/W Styler will look in the logfiles sub folder inside the B/W Styler folder to see if a preset with the name of the current image has been saved there. This preset may have been automatically saved by B/W Styler, because the Log settings check box was activated and you already applied a correction to this image (or an image with the same file name). If B/W Styler can find a preset file, it will immediately open it. If B/W Styler doesn't find one, nothing will happen.
Here you can choose the interface language. The help texts will also be displayed in the chosen language.
Multi-CPU Off (x CPUs)
If you encounter any problems, you can deactivate the support for multiple processors and hyperthreading processors with this check box. The multiprocessor feature currently only extends to the following effects: (Film) Grain, Paper Grade / Multigrade, Diffusion / Soften, Vignette Blur and Dark Mist. If one of these effects is chosen in B/W Styler, the rendering will be 7% faster (hyperthreading), 20% faster (dual core) or 30% faster (quadcore).
The number in brackets displays how many processors were detected by B/W Styler. For example, for a hyperthreading or dualcore processor you will see "2 CPUs" displayed. If you only have a non-hyperthreading, single core processor, this check box will disabled by default.
If the Instant Preview check box is activated, the preview is updated while you drag a slider. Additionally the dragging of the split view separation line is done interactively. Instant Preview may work too slowly on computers with an older processor. You can also get the same effect if you hold down the Shift key while dragging a slider.
Vertical Sliders (Windows only)
The Vertical Sliders check box will rotate the seven sliders of the B/W Films mode (as well as the same sliders on the Selective tab sheet in B/W Quick Mode and Expert Mode) by 90 degrees and orientate them vertically.
Activating the Histo Zoom check box in the Prefs tab cuts off peaks for some images when displaying a histogram in the Histo tab sheet. This avoids a flat histogram display where only a few high spikes are visible. That's also how Photoshop displays histograms. This option is activated by default.
With the Log Settings check box activated B/W Styler automatically saves a preset file in the logfiles sub folder of the B/W Styler folder when you press the OK button. In Photoshop and Paint Shop Pro the presets are named with the file name of the image. In other applications a random number is used, because these applications don't supply the file name of the image to plugins like B/W Styler. If you apply B/W Styler a second time to the same image and have Log Settings activated, the previous preset file will be overwritten.
At least with Photoshop and Paint Shop Pro this feature allows you to easily find the settings that you applied to certain images by looking into the logfiles sub folder. For other applications you can only look at the file date and guess which preset file was used for which image.
In connection with the Logged Settings option of the On Start Up combo box (see above), you can use the Log Settings check box to automatically make B/W Styler start up with the settings that were applied the last time to the same image. So if you need to correct the same image again, you will automatically be presented with the same settings that you used the last time.
In case you don't want to start up B/W Styler with the logged settings or forgot to activate that option, you can also open the logged settings by right clicking on the Reset button and choosing "Logged Settings" from the context menu.
