This question already has an answer here:
I am a beginner photographer who owns a Canon 700D (upgraded over my 1200D), planning to learn flash photography. Honestly, I am not a fan of using flash till now, but it seems for indoor shooting, flash is kind of necessary in low light. Can someone explain to me what I should be looking at when buying a flash? As a beginner I did some research and found that Yongnuo has some pretty budget-friendly flashes on the market. But I'm not sure what features to look for.
My primary requirements are portraits and indoor functions photography.
