Answer: Organisational innovation
Explanation: Organisational innovation refers to the application of some new method or any innovation that will enhance the organisation, business, environment, interpersonal or external relations. In this example, it is a store that sells images, and it is normal for innovations to be made to increase light flux both during the day and at night to make the images more visible, more prominent and easier to sell. The reason for these and many other types of innovation is the progression to keep up with the competition if not to go one step ahead.
