Jay Maisel always says to bring your camera, ‘cause it’s tough to take a picture without it. Pursuant to the above aforementioned piece of the rule book, subset three, clause A, paragraph four would be…use the camera.
Put it to your eye. You never know. There are lots of reasons, some of them even good, to just leave it on your shoulder or in your bag. Wrong lens. Wrong light. Aaahhh, it’s not that great, what am I gonna do with it anyway? I’ll have to put my coffee down. I’ll just delete it later, why bother? Lots of reasons not to take the dive into the eyepiece and once again try to sort out the world into an effective rectangle.
It’s almost always worth it to take a look.
