📷ISO invariance allows you to boost or drop exposure in post-production with minimal noise
🔍ISO invariant cameras, like the Sony Alpha series, produce cleaner images at high ISOs
📸ISO variant cameras, like Canon DSLRs, produce noisier images at higher ISOs
🌃To test if your camera is ISO invariant, shoot a low light scene with different ISOs and match the exposures in post-production
📊ISO invariance can benefit low light photography and post-processing flexibility
