If I walked into a paid job for a wedding, some photoshoot with just my iPhone...I deserve to be kicked out immediately, and blasted online, 0 out of 5 star reviews, etc...LOL
I just nod my head to myself every year when the event shows the iPhone example shots. I swear the same ...or almost the same quality was shown on an iPhone 7 or 8! Can that be achieved? Perhaps...with perfect lighting, and.. I dont care what anyone says...there is post processing involved in those shots.
In the end, I just simply enjoy hauling my camera bag...DSLR, the lenses, tripod. Manually adjusting the different shots, exposures...etc.
