Exposure compensation is an exciting feature of your camera. It’s here to help you efficiently manage the exposure and brightness of your photo. Do you want to learn how it works and what it can bring you on your next reports? that’s good, and we talk about it in detail.
Before talking to you about exposure compensation, I wanted to come back to the notion of exposure. In photography, we speak of exposure to express the brightness of a photo. A so-called underexposed photo will be too dark and an overexposed photo too bright. But too dark or too light for what? Compared to average exposure, ideal for shooting in progress. And what defines this “good” exhibition?
It is a somewhat subjective notion. But there is a scientific way to define it. Without going into too much detail (we will surely come back to this in another article), your device can set a good exposure, based on the distribution of the luminosities of all the pixels in your image.
To shorten again, it will take an average of the different values of each pixel in your photo on 1 alternatives, and then define an ideal exposure so that this distribution is optimum. We are simplifying obviously because the goal is not to explain all these concepts to you in detail in this article. But that’s pretty much how the algorithm works. And so, thanks to that, when you trigger a photo, your camera can offer you settings that will produce an image with this calculated ideal exposure, Of course, since it’s a calculation, there are times when this estimated exposure is not right.
This is why camera designers created this feature, which allows you to correct the exposure offered by your camera. On your device, look for the +/- button to access the exposure compensation function.
