This image is the free standing film SmA phase of the Schiff base at 91 degree C. Schiff base was synthesized by condensation of 4-nonyloxy salicylaldehyde and 4-tetradecyl aniline. The film was prepared by heating sample on the metal plate having a pin hole in the center. When the temperature rises close to isotropic temperature the sample was drag over the hole by a cover slide and the film was form after several attempts. The pattern observed in the film is because of thickness of the film; with a very thin film no such pattern was formed. The photograph was taken with 20X objective by Polarize Optical Microscope (LV100POL) with cross polarizer.

Jury comment: The long range ordered beautiful yellow texture obtained from the free standing film of SmA phase reminds morning glow.
