Exposure Index EXPLAINED in Cinematography!

🎥 Exposure Index vs ISO: Why EI Is Changing How I Shoot Log Footage A while back, I made a video on ISO and Exposure Index (EI), and it sparked a lot of discussion—and confusion. Especially around the idea that EI is becoming the new ISO. Watch the video on Dynamic Range and Negative ISO:    • Maximize Your Camera's Dynamic Range: Secr...   In this video, I break down exactly what Exposure Index is, how it differs from ISO, and why it’s such a powerful tool for modern cinematography. I’ll show you how EI affects exposure, dynamic range, and signal quality, especially when shooting in S-Log3 on Sony cameras like the FX6 and FX3. We’ll also look at how DaVinci Resolve now treats EI as the default exposure setting—even if you’re not shooting in RAW. 👉 Topics I cover: • Exposure Index vs ISO explained • How EI affects dynamic range and image quality • Real-world waveform and middle gray tests • Why DaVinci Resolve uses EI metadata • How I use EI to control exposure in post-production If you’re a filmmaker or cinematographer shooting in log, understanding how to use Exposure Index will give you more flexibility and better results—especially in low-light situations. For me, EI has completely changed the way I expose and grade my footage. And if you’re using DaVinci Resolve, you’re probably already relying on EI—whether you realize it or not. 💬 Drop your questions in the comments—I’d love to hear how you’re using EI in your own workflow. 🔔 Don’t forget to like, subscribe, and hit the bell for more filmmaking tips and breakdowns. 🟢 Download my free Camera Settings Cheat Sheet: https://www.cnomadic.com/cheat-sheet 🟢 Master the camera settings behind cinematic images: https://www.cnomadic.com/essential 🟢 Gear I Use On My Shoots: https://a.co/d/0dzJurXX As an Amazon Associate, I earn from qualifying purchases.
