📸 Smart Exposure Value Calculator (EV)

Analyze the relationship between Aperture, Shutter Speed, and ISO to find the perfect Exposure Value (EV).

ISO (Sensitivity)

Higher values favor low light but increase image noise.

Aperture (F-Stop)

Lower F-numbers create stronger background blur (shallow Depth of Field).

Shutter Speed

Faster speeds freeze motion; slower speeds allow dynamic blurring.

Please select all three settings.

Aperture (F-Stop): Controls the size of the lens opening. A lower F-value means a wider opening, increasing light and decreasing the Depth of Field.
Shutter Speed: The duration the shutter remains open. Faster speeds freeze motion, while slower speeds capture movement blur.
ISO (Sensitivity): The sensor's sensitivity to light. Higher ISO brightens the image but introduces digital noise (grain).
