When I began to get more interested in making photos and capturing the world around me, I would so very often run into a trap: while walking through the forest, some light on the trees is extra beautiful, and I raised the camera and made a photo of it.
And at home, there was simply nothing to see, the magic was gone, I was unable to capture it. I wondered how much talent it really takes to create successful photos of all these beautiful things. And well, there are two problems with my approach: 1. I'm moving and 2. I'm using both of my eyes to evaluate the scene.
I bet this sounds completely stupid, but for me, one of the biggest helpers to decide "should I try to make a photo of this?" is to hold still for a moment and then check: does the scene still have this appeal when I stand still?
And then I close one eye and look at the scene again. Because thats what the camera is: a poor one-eyed piece of gear. If the scene I saw still looks good with one eye closed, it will look good through the viewfinder.
And this method has saved me countless futile attempts of trying to capture what simply can't be captured with a camera.
