Apple’s iPhones have always struggled with HDR. The 7 Plus is not as smart as the Samsung Galaxy S7 at recognizing when to shoot in HDR, and I had to manually turn it on when facing high contrast lighting. For example, in this shot below, I was surprised when the 7 Plus didn’t automatically turn on HDR mode, as the highlights are obviously being blown out.
With HDR manually turned on. The highlight still looks hot to me, but my histogram assures me that there are no blown highlights.
The 7 Plus still struggles with difficult scenes. Here, the iPhone 7 Plus expertly kept the white highlights on the flowers, while boosting some of the shadows, and tried to retain the background but failed.
The S7 doesn’t fare much better. While it does okay with boosting shadow detail, it tends to let more highlights go. Neither of the three smartphones are particularly impressive when it comes to HDR, but the iPhone 7 Plus does slightly better.
