If you have never tried it, how can you honestly say it won’t work for you?
Okay, this is not to start a debate over which is better, using natural or artificial light, but to express what buying a single speedlight taught me.
It pushed me completely out of my comfort zone. If you have never used a flash you start at the scary and maybe frustrating point like everyone else. You don’t have a clue how it all works but with some perseverance, studying, and practice you quickly get the hang of it. Nothing new is gained without grinding it out until you figure it out.
It taught me about light. Until I learned about inverse-square law and started experimenting with moving the artificial light around my subject to understand light’s behavior, I just picked up the camera and took a shot of someone without thinking about light sources and how it plays on my subject. Now, even in a natural light setting, I am very conscious of posing my subject based on how they are being illuminated.
It gave me options. Learning to use speedlights and studio strobes has allowed me to expand my creativity as a photographer and have the ability to add light when needed to enhance the shot. It really does open doors of opportunity.
Yongnuo YN600EX-RT Flash Speedlite was my first.
