This word originally came from a professional pregnant women photography organization in Beijing. The main principle of their proposed "Pregnancy Photo Craze" was that: if we want to develop the cause of pregnant women photography in China, we must improve the shooting desire of expectant mothers. But how to improve the desire of expectant mothers? They launched an event called "Pregnancy Photo Craze", and won the crazy favor of expectant mothers with diversified and innovative photography styles. Expectant mothers posting their pregnancy photos on various websites and forums have slowly become a trend. All kinds of media also reported it one after another. Since then, the word "Pregnancy Photo Craze" has quickly become popular. In June 2009, the pregnant women photography industry, which had been quiet for a long time, welcomed a historical spring. Beijing - as the pioneer of Chinese pregnant women photography - was even more bustling, and all the pregnancy photo studios were fully booked. And customers must make reservations more than a month in advance. Various institutions had no choice but to operate overtime. All kinds of media and online platforms frequently featured various pregnant women photography styles, which greatly stimulated the shooting desire of expectant mothers. The number of Beijing pregnant women photography studios and photo studios increased dramatically. Everyone wants to get a share in this emerging fashion trend. According to surveys, a studio used to be very good if it could receive two pairs of customers for maternity photos every day. Since the outbreak of the "Pregnancy Photo Craze", the most in one day can reach about 10 pairs. And on average, there are at least 5 pairs per day. Calculating by the average shooting time of about 3 hours per pair of customers, I really admire the working attitude of pregnant women photography workers. Now, most of the medium and large cities in China have successively掀起ed a large-scale "Pregnancy Photo Craze"! It has even spread to Japan, South Korea and even all over Asia. Pregnant women photos have been recognized by ordinary people!
