High ISO photography is often something experienced photographers tend to avoid. The higher the ISO sensitivity, the more noise is introduced, and noise is often equated with reduced image quality. Many creators set their own limits on ISO levels to maintain practical image quality with their equipment.
However, depending on the creative approach, camera capabilities, and post-processing techniques, high ISO photography can also be embraced as a unique method.
Expressing the Grainy Texture of Film
Film photography has a distinctive grainy texture. This texture, created by the silver halide crystals on the film's surface, is one of the key elements that define the "film look."
In other words, adding this grainy texture to digital photos can recreate the warmth and nostalgia of film photography.

The noise introduced by increasing ISO sensitivity can naturally incorporate this grainy texture, making it possible to achieve a film-like expression even in digital photography when used effectively.
Cameras with Excellent High ISO Performance
When lens or shutter speed limitations prevent sufficient light from being captured, increasing ISO sensitivity becomes necessary. To address this, many manufacturers offer cameras with excellent high ISO performance, ideal for low-light photography.

For example, Sony's α7S series is a standout model among the company's full-frame mirrorless cameras, specializing in high sensitivity performance. Additionally, models like the Canon EOS R6 Mark II and Nikon Z6III are also excellent choices for high ISO photography.
These cameras can suppress the impact of noise even at high sensitivity, allowing for smooth shooting in low-light conditions.
AI-Powered Noise Reduction
With digital photo RAW data, it has become relatively easy to reduce high ISO noise. Many creators use general RAW development software to reduce noise with just a click of a button.
However, traditional noise reduction methods often resulted in a loss of sharpness. Recent advancements in AI-powered noise reduction technology have addressed this issue, sometimes even enhancing sharpness compared to the original image. A notable example of such software is "DxO PureRAW."
As AI-driven noise reduction technology continues to evolve, the reasons to avoid high ISO photography may soon disappear entirely.
