Using Different Lenses

The focal lenght of lenses determinises how magnified the objects in the image will be. The focal lenght increases along with physical distance from the subject, while maintaining the framing.

This is my attempt to create this effect.

The fact what different lenses can do is really interesting, even though i did not quite manage to create the smoothest transision i understand more how and what focal lenght to use when taking portraits. I enjoyed doing this exercise, i think it helps to develop spatial thinking.
