While the iPhone 15 Pro comes with many awesome features, the ability to shoot video using a log profile is seriously cool.
Shorthand for logarithmic profile, log profiles are types of gamma correction profiles or gamma curves. Without getting bogged down in the science behind linear light recording and logarithmic light recording, and how sensors and eyes/brains view light differently, a log profile is essentially used to increase the dynamic range that a camera sensor can record. A log profile squeezes more luminance data into a file through compression.
Log footage isn't designed to be viewed as is. When you view something shot using a log profile, you'll see that it looks flat and needs to be color and exposure corrected to look more pleasing. That's because as we mentioned, the purpose is to record more exposure data, allowing a wider dynamic range to be captured. More details will exist in shadows where non-log footage may have just recorded black. Likewise, more detail can be recovered from blown out highlights where non-log footage would have recorded simply white. This allows filmmakers to shoot in more challenging lighting conditions, while giving them more flexibility and control over exposure levels in post-production.
As such, it really is a welcome upgrade for anyone who wants to shoot video seriously on their iPhone 15 Pro or iPhone 15 Pro Max. It's also another demonstration of Apple really trying to follow through on the "Pro" moniker, and move towards the whole 'Shot on iPhone' thing becoming more than just an Apple marketing slogan, and actually a reality for serious filmmakers.
