You’re probably thinking to yourself: “Great! Now I understand how to use the EV compensation button. I shot in Aperture Priority so my aperture stays the same so I’ll only note (for curiosity’s sake) the shutter speed changes that the camera selected. The 1st shot is without EV compensation, in other words how the camera sees proper exposure.
NB: You cannot use the EV button to under or overexpose your photo in M (manual) mode since you control both the shutter speed and aperture manually. In A mode, the camera will change the shutter speed since you manually control the apperture. In S/Tv mode, since you set the shutter speed manually, it will adjust the aperture to compensate. In P mode, the camera will adjust the EV by changing the shutter speed and/or the apperture.

You can use the EV button in P (programed auto), S or Tv (shutter priority) or A (aperture priority) modes. 😉 When you play with the EV button, what you’re doing is telling the camera to either brighten or darken the photo from the optimal exposure it perceives. Some cameras do this better than others but that’s another story. When you’re taking a photo, the camera’s job is to adjust itself by changing the shutter speed and/or apperture to properly expose your shot so that it’s not too bright or too dark. To put it simply, the EV button allows your to quickly underexpose (darken) or overexpose (brighten) your image. But before I get into that, let me briefly explain to you WHAT the EV button is and what it does. Remember that I shoot with a Nikon so shutter speed and aperture are controlled with the front and back wheels not buttons ). I’ve been using the EV (Exposure Value) button on my camera more than any of the other buttons so I thought I would share with you why and when I use it. Today Yanik Chauvin from Image-Y shares how he uses EV Compensation.
