So I crop 1/5 of the image and boost the exposure 2stops. If I do that with a camera just a few years old, the result is terrible.
Now obviously, if the image is bad or completely uninteresting to begin with then no technological thing is going to help. But it's nice crutches for beginners. After I cropped my image to 1/5, I learned what I should have done. In the past, that was a really expensive lesson (the photo was ruined). Now I get the lesson AND the photo.
"That's so kind. You have a great mouth!"
(Saw this in a comic somewhere - sadly, I can't find it any more).
When I showed it to family members, most of them liked it. Then one of them asked "What camera did you use to take this picture?"
I said "Just an old 6x6 Japanese box, loaded with Portra 400" Maybe someday I'll visit that place again, shoot a 4x5 and make really huge print of it :D
I've mainly found exposure to be much easier to manage with a good camera.
† Tip: (thank you non-discoverable UI) The default iPhone app can lock AE/AF by loooooong-touching until it locks, and you can adjust exposure compensation by sliding up and down, but the former is a AF lock (not a manual set) and the second one is both highly imprecise and takes ages to go through large ranges when AE screws up. ProCamera's UI is both much more intuitive, responsive, and full-featured.
My 300 EUR camera can focus on the eye, and my 1.8f lens will make the background blurry. All I add is rule of the third. The camera will also measure the exposure according to the face.
And suddenly I made a photo that other people find aesthetically pleasing.
It's going to be interesting ones artificial blur / bokeh and AI compositions are mainstream.
This article hits on a key thing - the main things controlling the quality/interest of a photo are composition, subject, and exposure. The main dimension "really good camera!" helps in these days is resolution, which has approximately zero to do with photo quality.
edit: I have a print of a favorite photo of mine above my fireplace mantle. It was shot with an old Motorola RAZR, at 320x240px. It's pixellated like crazy in print. It's also full of high-contrast problems - a large blown-out splotch off center from directly facing a light, and the mere shadow outlines of numerous hands in he air in the foreground (it was shot at a Flaming Lips concert). It's epic and beautiful. Why? Good composition, and interesting subject matter (hands in the air, facing a shadowy barely-recognizable human outline).
Great camera, indeed.
