Mr Bubbles, on a somewhat similar note, I am terrible at taking photos of people.
I have worked with photogs that excel in this. They have a way with people, a care and lack of self consciousness that I can not master. I shoot wildlife mostly, and then, I am alone with the beasties, in my zone.
I have lots of great high end gear that help me be able to capture the moment for wildlife and action photography, and in my comfort zone, I can use these tools to bettwr capture my vision, to improve the chances of the camera reacting to the timing I;m looking for, and I can be creative.
But since I suck at working with people, and I have poor people "SKILLS" and also lack the "skill" to be creative and form a good vision when shooting people, despite all that high end gear, my shots suck.
No amount of gear will help me make better people photos.
