Most people might think that photography is math free, that they just have to press a button. While, that's not wrong, you do essentially just press a button, there's a lot of math that goes into taking a picture.
It's pretty much in every part or step of taking a photo. From the shutter speed, to just getting the framing right. Now, I know that you might not understand what these terms mean, but we'll get to that, don't worry.
As you can see, math is very much a part of digital photography. It's crazy how so many people don't even consider the amount of math involved when taking a picture. You press a button, but before you even lay your finger down, so much math has gone into making sure the lighting and the framing is just right.
