Using a preset, you produce uniform images with the person’s head in a defined position within the image and consistent margins around it. It may happen that the original image is too small or the person’s face is too large for the used preset, causing the cropping box to extend outside the image bounds.
By default, the program shrinks the cropping box to fit within image borders while keeping the center point of the face in the position defined by the preset.
If you want to keep faces the same size and don’t care about visual background quality, for example, if you’re making green screen photos for background removal, you may want to keep the face size by expanding the image bounds.
Outside areas will be filled with the color of the top-right point of the cropped rectangle. If you shoot your models against a plain color background (like a green screen for future background removal), you’ll get good results suitable for further work.
You can define this behavior in program preferences for all images or in a preset for particular presets. This option can be set when you edit presets as a text file. It is named OversizeMode.
There are three modes:
OversizeMode:0 - uses default mode defined in preferences
OversizeMode:1 - override defaults and allow oversize
OversizeMode:2 - override defaults and shrink to fit
Below are examples of images with an oversized crop. Please keep in mind that oversize may occur when you straighten or tilt the picture. Note that oversized faces have red borders in the file list.
You can review images with that problem by selecting the drop-down popup “Contains Oversized Crop.” This will leave only oversized images in the file list.
