Metapho identifiziert „Deep Fusion”-Fotos
Metapho 3.4.2 indicates Deep Fusion and Night Mode under the Image Information section. How?
For Deep Fusion, it’s flash EXIF metadata field. Ever since iPhone 4 introduced that tiny camera flash, normal photo taken with back camera without flash firing has integer value 16 in the field. A deeply fused photo has 32 — means no flash function, so Metahpo can read this field and compare iPhone model number to determine it’s Deep Fusion or not. I hope that Deep Fusion writes 32 to the flash field, is well intended thing and remains consistent.
Night Mode is more straightforward. It has couple of dedicated EXIF tags indicating the number of composite image used, and min/max/sum of multiple exposure times. Since a single Shutter Speed time loses its meaning for Night Mode’s compositing of multiple images, I’ve replaced Shutter Speed field under the Camera Information section for these fields.
