Actually what you should do, if you have access to a raw image processing software, is to set your camera to capture in RAW but set the camera to display BW on your LCD monitor.
One of the tough choices when peering into the viewfinder is deciding how much of the scene we see is important.
It’s often overwhelming.
If you stood in front of the Grand Canyon, Niagara Falls (insert your choice of natural wonder or manmade structure), you’re likely seeing something massive.
Our eyes function like a camera but we have a brain attached to them.
The camera requires “us” to decide, to choose.
If we can’t decide, we end up sticking a wide angle lens and taking everything in.
