Photography Tips
Use hyperfocal distance for landscape photography
Smaller sensors have closer hyperfocal distances
Wide-angle lenses have shorter hyperfocal distances
Smaller apertures (higher f-numbers) increase depth of field
Perfect for astrophotography and cityscapes
Understanding Hyperfocal Distance
What is Hyperfocal Distance?
Hyperfocal distance is the closest distance at which you can focus your camera while keeping objects at infinity acceptably sharp. When you focus at the hyperfocal distance, everything from half that distance to infinity will be in acceptable focus.
Why Use Hyperfocal Distance?
- •Maximize depth of field in your photographs
- •Perfect for landscape and architectural photography
- •Keep both foreground and background in focus
- •Essential for astrophotography
Hyperfocal Distance Formula
H = f + f²/(N × C)
- H: Hyperfocal distance (mm)
- f: Focal length (mm)
- N: f-number (aperture)
- C: Circle of confusion (mm)
Circle of Confusion
The circle of confusion is calculated as the sensor diagonal divided by 1500. This determines the acceptable blur for sharp focus and varies with sensor size.
Practical Applications
Landscape
Keep mountains and foreground rocks in focus
Cityscape
Sharp from nearby buildings to distant skyline
Astrophotography
Focus from ground elements to stars
