Exposure Index EXPLAINED in Cinematography!

Описание: 🎥 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.

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.
