To apply effects and/or color corrections to your photo, first, select an image on your page, then click on the Image FX tab. The Image FX editor will open.
Brightness, Contrast & Saturation
Brightness, contrast and saturation controls are generally used for image correction. Be very careful when using these on your photos - your monitor is most not likely professionally color balanced, so the end effects on your printed book may be more dramatic than intended.
Brightness affects the overall amount of light in your image.
Contrast affects the amount of difference between light and dark areas in your image.
Saturation affects the intensity of color in your image.
Grayscale & Sepia
Grayscale and sepia are color effects. Grayscale removes the color from your image.
Sepia replaces the color with brown/golden tones, for an antique look.
Hue-rotation, Invert & Blur
Hue-rotation transforms the colors in your image. It does not tint your photo, but shift the color on the color gamut.
This slider option is best used to reversion backgrounds & clipart to match your page's color scheme. Turn one background into multiple color variants, or retint cliparts to a theme color.

Invert reverses the color in your images.
This option is best for applied to backgrounds more than your photos.
Blur defocuses your image.
Apply this to soften images and textures for a diffuse background effect.
Opacity
Reducing opacity makes your image more transparent. Content underneath an image with reduced opacity will be seen through the photo.
It can be used effectively to create a layered effect. In this example, clipart is transformed into transparent stickers.
Horizontal Flip
Turn on horizontal flip to mirror-image photos on a left-right axis. Turn on vertical flip to mirror-image photos top-down.
This effect is useful for creating "bookend" clipart.
