Photo Exposure Calculator: How to solve the specific challenges in the shoot?

The exposure calculator is not just a simple digital conversion tool, but a "brain" for photographers in the face of complex photo-cannon challenges. The understanding and flexible application of the efficiencies of the exposure triangles (radio-circle, fast-door, ISO) - whether for beginners or professionals - are the basis for the creation of high-quality images.

1. Addressing the challenge of inadequate light (weak light environment)

The most common problem is that the picture is too dark when it is taken indoors or at night. Using the exposure calculator, you can explore a variety of options:

Option A: Increase the arctic circle (to lower f). For example, from f/4 to f/28.8, the amount of light going in doubled, so you can keep ISO low To reduce the noise.
Option B: Extend the fast door. If you shoot a static object, you can get the fast door down from 1/60s to 1/15s Double the amount of light, but you need a tripod to prevent the shaking.
Option C: Raise ISO. It's the last thing, it's bright, but it increases the image's particle sense. Calculator will help you find a balance.

2. Balance between motion blurry and instantaneous

When you shoot a kid in a sports game or running, you need a fast door. 1/1000s）。 But the door is fast, and the light is low. At this point, the exposure calculator will recommend that you:

Lock the speed of the fast door by increasing the arctic circle or increasing ISO To fill the lost exposure. This equivalent ensures that you can both take a picture of your actions and not make it dark.

3. Creative depth control: large or small?

If you want to take a false image of the background, you need to use a big radiant circle. f/1.8）。 But in the light, it leads to exposure. Calculator tells you how fast you need to fit the door. The filters are used to offset the excess light from the big radium. On the contrary, the great wind photography requires a small radiant circle. The calculator will remind you to extend the fast-door hours.

What is the value of the EV? What does it mean to be a photographer?

EV (Exposure Value) is a set of numbers that measure exposure levels. EV 0 corresponds to a combination of f/1.0 and 1 second. EV For every increase in value, the light is halved.

EV 15： Outside the sun.
EV 12-13： The sun or the morning/the evening.
EV 5-7： Typical indoor light environment.
EV-3 to 1: Starry or extremely weak light environment.
