If you're using Adobe® Photoshop® Elements, our installer will automatically detect the editor on your system, and after installation (and a restart of Photoshop Elements) AstroFlat Pro is found under Filter in the main menu.
Open your image, then click on Filter in the Adobe® Photoshop® Elements main menu and hover over ProDigital Software in the drop down menu. You can then see and click on AstroFlat Pro...
Photoshop Elements also gives you direct access to our About Dialog. There you can see the version of the plug-in, as well as change configuration options and find some other useful information about AstroFlat Pro. You don't even have to load an image.
To see the AstroFlat Pro About Dialog in Adobe® Photoshop® Elements, click on Help in the Adobe® Photoshop® Elements main menu then select About Plug-in. This will present another menu with a list of your plug-ins that have About Dialogs. You will find AstroFlat Pro... toward the beginning of the list.
