2 Lies About Image Sharpness That You Thought Were True

For example, most beginners think that the pixels determine how sharp an image your camera can produce.

It may seem that way but there’s more to it. The more pixels, the more details you can capture and it can make a difference in large print sizes. However, it doesn’t directly improve the sharpness of your photo. Here are some other myths about image sharpness that are not necessarily true.

Mirror Lock-Up Prevents All Vibrations From The Camera

Unfortunately, this is not true. Mirror lock-up moves the mirror inside the camera well before the shutter is released so that any vibrations from the mirror slapping the camera is gone when the photo is captured. However, this does not prevent vibrations from the shutter movement. These vibrations are typically very small, and you probably won’t ever notice them unless you’re trying for a very long exposure and pixel peeping at the maximum. This is not to say that you shouldn’t use mirror lock-up. Mirror slap can be a problem in long exposures and this mode can keep your images from being blurry.

Faster Shutter Speeds Will Give You Sharper Images

This is not necessarily true. Faster shutter speeds will generally give you sharper results if you or your subject is moving. If your subject is running or if you are shakily hand-holding the camera, a fast shutter speed will freeze the action and make your shakiness negligible. However, fast shutter speeds do not equal sharp images. If you were to take a photo of a stationary object while your camera was also set on something stationary, it wouldn’t matter if your shutter speed was 1/500th of a second or 30 seconds. If neither your subject nor your camera moves, the sharpness would be the same. This is assuming that all other settings are the same. If you change your aperture or ISO settings, then there will be a difference in sharpness.
