In each dish , you put the pot on the stove or in oven, set temperatue and heat it for some time. In the end, you can get food that is cooked properly and ready to eat. Or ... if you're not so good in your assessment or not experienced, you will end up with half-cooked food and raw or cooked and burnt.
The most important concept of photography is to get proper exposure ( perfect exposure ) on your images. Exposure is basically the amount of light that allows you to reach your camera sensor. Getting the proper exposure is like cooking. You allow too much light and most of the picture will be overexposed like the food will be burned with too much heat. On the other hand, if you do not allow enough light, your picture will be underexposed as not applying enough heat to your dish will be left half done.
