How does light work and how does it affect its surroundings? That was the challenge I focused on this time. 

I set up the background behind the physalis plant, thus I could keep the merit of the sunlight on my object. (See the following image.)

I've decided that the upper fruit shall turn into a light bulb! And this kept me thinking about how surrounding colors shall change or even how textures are affected by light. (Yes, taking the entire front mesh by removing the strong orange behind it was part of this process.) 

The bulb light is on a lower level to keep the eye-catching husk.

I hope you enjoy the result as much as I did while creating it. This study really enlightened me. ;)
