Instagram has also had a significant influence on professional photography, with a growing number of photojournalists adopting the image-sharing mobile platform to establish enormous groups of followers, according to Olivier Laurent of the British Journal of Photography. They use the platform not only to share their work but also to discuss issues in relation to war, violence, and human rights. Photojournalists use various techniques and tools on Instagram to attract readers and viewers to their work. Some post single photographs while others use videos or photosets. Some photojournalists may even use special effects or background music to create an immersive experience for their audience. In addition to using social media to reach an international audience, many photojournalists also use it as a way to communicate with their peers and show the world their work in a new light. For example, photographer Paul Conroy uses his account to share images that he cannot fit into his regular work. "The Instagram account is really important for me because it's my creative outlet," he said. "I take pictures I don't usually take at conventions or meetings." Photojournalist Emad Abazid uses Instagram to document the lives of children in Syria. The 23-year-old student at Boston University began posting photos of Syrian refugee children on Facebook in 2012.
