Your image’s tonal distribution
Dark ← brightness → light. Clipping is counted before noise is added. Noise is an illustrative model, not a prediction for a particular camera.
AI-generated photographic artwork. Preview exposure and depth of field are simulated.
Keep the brightness. Change the feeling.
At fixed scene lighting, the light collected scales with shutter time divided by the square of the f-number. Doubling the ISO approximately doubles rendered brightness, but does not bring more light through the lens. Try “Freeze the ride”: a shorter shutter collects less light, while higher ISO brings the brightness back with more visible noise.
Scene assumptions & simulation limits
The focus model uses an ideal 85 mm lens, a full-frame image width, a subject at 4 m and a background at 12 m. Depth of field uses a 0.03 mm acceptable blur circle. The cyclist and background are flat layers; the entire background receives one blur amount. This teaches the direction of the effect rather than reconstructing the photograph’s depth.
Brightness is applied in approximate linear light, with simulated shot noise and read noise. Noise, color, dynamic range and clipping do not represent any named camera. The cyclist translates as one layer; its wheels and legs are not animated independently. White balance, flash, diffraction, lens transmission and stabilization are not modeled.
For more control over focus geometry, explore the bokeh simulator. For an exposure that is too long in bright light, try the ND filter calculator.
