Some photographers take pride in shooting purely in full manual mode. Anything less than M is not good enough for them. They feel superior to those who shoot in any other mode. I would like to clarify why I am against shooting in full manual especially if you are new to photography.
But first, let’s enumerate those few instances when you probably should shoot in M mode. Flash photography is one, for the reason that your camera would not be able to shoot faster than your sync speed which is typically 1/250s. Which means shooting in A mode would likely result in overexposure. Another instance is when stitching panoramas where you need to make sure that each frame would have the same exposure. Concert photography is also a good candidate because usually only the performers are properly lit while the rest of the stage is dark and the lighting effects are constantly changing. Your camera’s meter will go insane if you point it at the stage. Of course there are other instances when you might want to shoot in manual mode but those are rare occasions.
Now for those who shoot in M mode ONLY, let me guess how they are doing it. Point the camera, check the meter reading then line up the exposure slider. That’s really funny. If you are just lining up the sliders everytime you change your view, why the heck would you shoot in M mode?! Shoot in Auto, you know, that thing with the green square 🙂
Sorry, but again, if you can’t even set the proper exposure without checking the exposure slider then you have no reason to shoot in full manual. You will wear out your thumb wheel or your thumb, whichever comes first, really quick 🙂 Real macho photographers know the correct exposure just by looking at the scene. Real macho photographers know not to trust the camera meter. Matching the sliders is a joke.
What’s worse than shooting in M mode? Shooting in shutter priority mode or S mode. It usually means that the “photographer” does not understand depth of field, or worse, proper exposure.
So what’s the best mode? Yes, aperture priority mode or A mode. You have depth of field control and the camera can safely choose a wide range of shutter speeds between 1/8000s up to 30s. Compare with S mode where the camera can only choose between f1.8 to f22 and so much worse if you have a kit lens. Assuming that the ISO is constant, A mode is so much more flexible for the camera (18 stops for A vs 7 stops for S). And that is why S mode is a joke.
Now we know that the camera’s meter is not always correct. Do we have to use manual mode then? Nope, not yet. We have two arsenals at our disposal: 1) exposure locking, and 2) exposure compensation.
Let’s look at exposure locking first. Some cameras have dedicated buttons labeled AEL, for auto exposure lock. If yours doesn’t have it, the half click method should work. You basically point your camera directly on a neutral-colored object that is in the same focal distance to your intended subject, half click or press AEL, recompose then shoot. If you can’t find a neutral object, you could always meter off the back of your hand or a green leaf then press AEL while those that use the half click method will have to manually focus on their subject when they recompose.
Now let’s cover exposure compensation. Most cameras have a dedicated button labeled +/-. If yours doesn’t, throw it away because that means the camera is so dumb and the engineers are dumber. If your camera has two knobs, you could assign one of them to do exposure compensation. Exposure compensation usually has a visual slider that goes from -2 to +2. What this means is that if the camera meter reading is 1/250 at your chosen aperture and you compensate by +1 then the shutter drops to 1/125, -1 would be 1/500, +2 is 1/60 and so on. Cameras differ in the compensation steps. Some do it in steps of 1/3 stops and some in 1/2 stops.
Note to Nikon users: Nikon engineers failed in elementary math. They STILL think that the number line goes positive to the left and negative to the right. Smarter people change this behaviour in a setting hidden deep somewhere in the complicated menu. Be careful.
Here’s an example: Suppose you are taking photos at the beach. The camera will think that the scene is too bright and will underexpose and render the white sand as grey. Press +/- and set your exposure compensation to +1 or even +1.3 or +1.5, then shoot. You only have to do this once and can leave it at that setting for the entire shoot at the beach.
Another example: Candle light dinner date with your girlfriend in an expensive restaurant. You want to take a photo of her pretty face. Unfortunately the camera thinks it’s too dark and will overexpose and destroy the mood. Dial exposure comp to -1 then shoot.
What’s the moral of the story? Not shooting in manual mode does not make you a lesser photographer. Don’t let the macho togs fool you into thinking that they are better. Watch how they do it and if they are just lining up the sliders then they are no better than those who shoot in Auto mode. Understanding exposure makes you a better photographer. Master aperture priority mode and use exposure compensation. It’s so much faster and it does make you think about proper exposure.
Go out and shoot in A mode and don’t forget to use that +/- button. You’ll thank me for saving your right thumb.
