|PanGazer – enhance|
PanGazer’s image enhancements let you change the presentation of an image (brightness, etc.) to help you identify features of interest. Like the controls on a TV or computer monitor they let you alter your view of the image without changing the image itself.
PanGazer enhancements are intentionally potent; they exaggerate small differences. Other programs are better for fine-tuning an image for publication or printing; however, you can always save an enhanced view (without the status overlays, etc.) using Save current view as... from the Image or pop-up menus.
To change enhancements, open the Enhancements dialog box by pressing ‘e’, or by selecting Enhance view from the main Image menu or from the pop-up (right-click) menu.
You can then move any (or all) of the sliders; they all adjust values from −1 through +1, with 0 being the default (no change):
The four sliders are independent and have only a small effect on display performance. At any time you can click the Reset button to revert all the enhancements to default (that is, showing the original image, un-enhanced).
Click the Done button, press Enter, or close the dialog box when you no longer wish to see the dialog.
You can use Settings → Status Display → Show enhancement values to have the enhancement values displayed at the top left of the view even when the Enhancements dialog box is not open (this status is only shown when at least one enhancement value is non-zero).
