With the Photocrati Theme you have the option to select from 16+ built-in presets. You may also customize these presets further to be unique to your brand and image, using the Customize Theme panel under Theme Options >> Customize Theme. When you are finished with your customizations come here to Theme Options >> Choose Theme > Save Custom Theme to save your changes:
When you are finished saving, make sure to click 'Use _custom preset name_'. REMEMBER any time that you make a change to your Theme Preset, come back here to 'update' the custom preset.
An additional option that you have is that you can import and export your custom preset. This would be a good idea as an extra precaution in backing up your site. It also provides the extra bonus of sharing your custom presets with other Photocrati Theme users. 🙂
