Abstract:
E-commerce is one of the most popular selling channels and is perpetually growing. Most consumers make a decision to purchase merchandise based on photographs. To make photographs attractive, lighting setup techniques are required. One of the most popular lighting techniques is the 4-points lighting setup. In this technique, the fill light creates a contrast between the light and shadows from the key light. This research, hence, aimed to study the influence of the ratios between the key light and the fill lights on consumers feelings. Three types of pizzas were photographed with six different intensities of the fill lights. The subjects were 50 students from the Faculty of Mass Communication Technology, Rajamangala University of Technology Thanyaburi. They were asked to express their feelings towards the eighteen photographs using ten pairs of sematic differential scales including hard soft, dirty clean, static dynamic, fake natural, stale fresh, not delicious delicious, not luxurious luxurious, disliked liked, unattractive attractive, and low qualitative - high qualitative. The results showed that the photographs taken with the ratio of the key light to fill light at 1:1 (11000: 11000 lx.) had a higher mean score of the consumers feelings when compared with the ratios in any other pairs of feelings scales. In addition, when the light intensity was increased, the mean of the feelings tended to increase at a statistical significance (p<0.001). Also, it was found that there were correlations between the attractive and high qualitative feelings and the delicious and
luxurious feelings of the subjects based on the photographs.
