Image sources

Select the source of the image you want to manipulate here. You can browse the image folders on the device and on the memory card to choose a file. You can shoot a photo with the front or back camera (if available), too.

Loading modes

Switch between high color depth and high resolution image loading modes.

In high color depth mode, the images get loaded with their original 16 million colors (24 bits per pixel) used, but big images may be loaded with reduced resolution.

In high resolution mode, all supported images are loaded in their original size and the maximum scaling factor is higher than in high color depth mode, but the images get loaded with 65 thousand colors (16 bits per pixel), only.

The reason for implementing these modes is to provide the most possibilities to the user, although the memory on the devices is limited.

Please note that some devices can display 65 thousand colors, only (525, 533, 575, 723). If high color mode is used, the images will still be (internally) loaded, processed and saved with 16 million colors! So no color information gets lost in this case.

Preview modes

You can toggle between big and system preview mode.

The big preview mode shows the full current path and big high quality preview images with their files' names. If there are too many images in the current folder to get previewed as big images (due memory consumption) or there is already an image loaded in the editor, maybe not all files will be displayed (because there is not enough memory). PhotoRhino shows you a hint (can be disabled) and displays a dark red background, if this happens.

If you do not like that behavior or do not need big previews, the system preview mode is an option. It uses the system's media application to be able to browse images and select your source image.
