Hiking Tumalo Falls near Bend, Oregon is our first new hike of this trip. Yesterday we visited Paulina Falls, which was beautiful, but we'd been there once before, six years ago. In my blog earlier today I slow-walked the start of our Tumalo Falls hike, writing extensively about some of the tech of photography behind photographing waterfalls. Well, there's more. 😂

One of the differences I noted between modern iPhone cameras and traditionally designed (but still modern) dedicated cameras is that iPhones do exposure stacking. They automatically capture multiple frames of an image in rapid succession and then blend those frames together seamlessly to produce a single image that's presented to the user. It seems like you clicked the shutter button once and got one simple picture, but there's a lot of fancy computation and image processing happening inside the device. And partly it's doing that because there's so much computational power on board. The A18 processor in my iPhone, which is already a year-old model, is approximately 100,000 times more powerful than the computers that sent the Apollo 11 mission to the moon. And here I'm just asking it to take a better waterfall picture. 😅
So, what's better about it? Take a look at the rock wall to the right of the falls. In the photos I shared earlier (previous blog) it's hard to make out the details. Here, in this photo, my iPhone recognized that the shadowy area was a big part of the picture and worked to illuminate it better.
Compare that to a traditional dedicated camera, which really does capture just one picture and deliver it to you when you press the trigger:

...Okay, well, that rock wall to the right isn't too bad, is it. It's totally not all dark shadows. But that's because I worked hard in Photoshop to fix it. Even with my deft use of layers and masking and the "Shadows and Highlights" tool, there are still artifacts I could not avoid. Artifacts are those tell-tale fingerprints that indicate the image has been 'shopped, like the Photoshopped portrait of Princess Kate and her kids that sent people into a tizzy last year. And despite those artifacts that a trained eye easily spots, the shadow recovery I did in Photoshop with Tumalo Falls still doesn't look as good as the straight-out-of-the-camera (SOOC) photo from my iPhone 16 Pro.
Are other parts of my dedicated camera + Photoshop pic better? Absolutely. The richer colors in the second photo are SOOC, which is a huge reason I continue to lug around my dedicated camera and lens set even while my comparatively svelte iPhone is always in my pocket. Plus, as I explain in my previous blog, the motion blur on the water is an effect I can create SOOC with my dedicated camera that there isn't yet a practical way to do with an iPhone. Maybe soon, though; maybe soon....
