I am trying to figure out if I should stick to the Program auto exposure mode, or should I use full manual mode. Reading about technique is one thing. I just purchased a Nikon Z6 mirrorless camera and always use the viewfinder for focus and exposure. Let’s start with the same base exposure, where we set 1/250th of a second as the shutter speed: Dialing in -1 EV via exposure compensation will adjust the camera’s aperture from f/2.8 to f/4.0, while keeping the shutter speed constant: Whereas dialing in +1 EV will open up the aperture to f/2.0 and thus brighten the image: When shooting in Manual Mode, the only variable that can change is Camera ISO, but it first has to be set to Auto ISO, as pointed out earlier. To be able to do this, one has to use the Exposure Compensation feature, which is typically provided either as a dedicated button on a camera, or as a dial that one can move from positive exposure compensation to negative.

So you dial in a bit of exposure compensation, telling your camera to make some changes to its aperture or shutter speed choice. You can do exposure correction in post-processing. Or it might choose a shutter speed that’s too long, resulting in an overwhelmingly bright photo. Identifying the exposure compensation button on a camera is pretty easy – look for a button that has plus and minus signs, similar to the following illustration: And if you cannot find such a button, there might be a dial on the top or the back of the camera that goes from a negative value to a positive value, such as -3 to +3, with small increments in between.

If you cannot see those values after making changes, you might need to turn on informational overlays from the camera menu. When using exposure compensation, just remember that the + symbol indicates increased brightness. You can also use exposure compensation for an artistic effect (if you want a photo that’s dark and moody, or bright and airy). If you then dial in, for instance, +1 EV it will actually show you that according to this new overwritten value, you are 1 stop overexposed and so if you tried to bring the lightmeter indicator back to 0 by changing either your f-stop, shutter speed or ISO, you would end up with an overexposed image. So what is exposure compensation? Essentially, exposure compensation is a way of telling your camera to take its calculated exposure and then adjust the actual exposure in one direction or the other based on your preference.

In order to use exposure compensation, you must be in one of the camera modes that utilizes the camera meter, such as aperture priority, shutter priority, program mode, or any other “scene” mode that performs automatic exposure adjustments. When shooting in Aperture Priority mode, the photographer sets the camera’s Aperture, while the camera automatically sets the Shutter Speed depending on the reading from the camera meter. This allows for manual corrections if you observe a metering mode to be consistently under or over-exposing. So you have to rely on your camera’s LCD to decide that the exposure is off, and you have to make changes on the fly. No, that is not at all correct. If an image appears to be dark, you dial a positive number (+EV), whereas if the image appears to be bright, you dial a negative number (-EV).

In Manual, you set the ISO, aperture, and shutter speed yourself. Although I have stated above that metering systems on cameras standardize on middle gray, many of the modern cameras now come with sophisticated metering systems that are capable of recognizing scenes based on pre-loaded data and make necessary adjustments to the exposure, essentially minimizing the use of the exposure compensation feature. This bias can be set to achieve either more or less exposure than usual, and the result is an image that is either slightly brighter or darker than would otherwise be the case. Finally, you take a second photo–which should turn out beautifully.
