“I noticed that you take a lot of your pictures in low light, but still have good quality. Could you tell me how you achieve this?”
One thing I try to always have is one light source in a dark space, and adjust my exposure to the light.
I usually begin with having my aperture at the lowest F stop (F/1.4, F/2). That means the more light is allowed in, the higher your shutter can be, the less blurry your subject is.
What all of my lenses have in common is that they go as low as F/2. The lower the number in your aperture, the bigger the hole in the lens, the more light allowed in, the faster you can shoot.
So, in conclusion:
Have lenses with a low F stop capability
Adjust your ISO. The higher the number, the more grain, the more light being fed into your camera. [ISO is the light sensitivity of the imaging sensor. When you change the ISO on a digital camera, you’re rendering the sensor more or less sensitive to light. For film, you are essentially stuck with whatever film speed you loaded into your camera, until you finish that particular roll. Read more about ISO here.]
Have a light source
It can be confusing to see how aperture, shutter and ISO work together so my best piece of advice is to go shoot. Experience is the best teacher.
