What is ISO + How to get clean, Noise-Free photos every time
Confused by ISO? Most beginners think it makes the sensor "more sensitive." It doesn't. In this video, I use Oreo Cookies, Milk, and Jumper Cables to explain exactly how ISO works and why Digital Noise appears in your images.
I explain the difference between Film Grain and Digital Noise, and why shooting at a lower ISO might actually make your photos worse (The Signal-to-Noise Ratio).
