Example methods are disclosed for encoding variable sized data using a low-density parity-check code, and transporting the encoded variable sized data in modulated symbols. Other herbal substituents which further enhance this novel composition are disclosed including motherwort, bilberry, fresh dandelion root, and ginger root. The required-formation-amount-related value in the multi-layer data is image data that exceeds a maximum-formation-amount-related value representing a value relating to a maximum formation amount of a color value of the single-layer data with which an image can be printed in a single printing process. In this manner, embodiments of the present invention can correct possible optical imperfections of resultant images produced by the combination of the built-in camera lens and auxiliary lens selected for focusing andor image capture by the user. The interlocking and bracing mechanisms have an open state and a closed state.
