Do not buy more gear. Do not get technical. Do not worry about Photoshop.
DO WORK ON YOUR PEOPLE SKILLS.
If you are disappointed with your photographs, start asking yourself if you could improve upon your people skills. How can you do this? Take an interest in your subjects. Start conversation, create some ice breakers…. LISTEN to them. Be engaged. This will help you be more intentional and I guarantee your photographs will start taking on a new life.
Especially where portraits are concerned, People Skills Trump Camera Skills every time.
