your aperture, a “stop” up or down lets in twice as much or half as much light into your sensor compared to the “stop” beside it. Mastering Aperture is a key to well-developed images. the overall parameters of your image but it also has a multiplier effect, which makes the lens you are using 50% longer. So you using a 50mm lens and it’ll multiple to look like an 85mm. Shutter: ISO:   The Shutter on your camera is a curtain that opens and closes letting in light for a specified duration of time. The quicker the shutter opens or closes the less light is let in. So on a sunny day at the beach perhaps a shutter speed of 1/8000th of a second is necessary. As the light dims you need to adjust the shutter speed to 1/500th or even 1/250th of a second.  Some cameras can allow the shutter to be open for hours. This is useful for those middle of the night images of star trails. ISO is essentially the sensitivity to light that your sensor is set at. So for example, if you are photographing in brightly lit conditions then an ISO of 100 is sufficient because your camera does not have to be sensitive to light. The light is already present. But as the light deteriorates you will need to bump up the ISO to become more sensitive to the fading light.  Crop Sensor: Usually when buying your first dslr, you’ll buy a camera with a crop sensor. Meaning that the sensor in your camera is smaller than 35mm. But that does not only effect
