You’ll be surprised at how good the iPhone 12 Pro Max image files look on a computer screen. Better than just for social media. You have to know what you are doing as a photographer, you have to train yourself to think like the camera sees. Then you’ll be a great photographer. I started at the age of 18, I’m 51 now..
When Apple ProRAW was introduced, it became a game changer in iPhone photography along with the LIDAR sensor. Sure iPhones without this feature produce decent to really nice jpeg images if you pay attention to your highlights and not blow them out. The red channel in the histogram usually gets over exposed first. Once you blow the highlights on a jpeg image, the detail in those highlights can’t be recovered.
This past winter I took a photo of a frost covered oak tree leaf, a large one and had it printed to a 16x20, it looks fantastic. this was with the 1x or wide camera with the new 47% larger sensor compared to the 11 pro max. So don’t be fooled or have the mindset that iPhone photos are only good for small prints & social media. I took several raw files from my iPhone 12 Pro Max and loaded them into Lightroom on my desktop. The images were fully edited to where it looked it’s best, sharpening, noise reduction (if needed), clarity, highlights, etc, etc. after the image was complexly edited, I loaded those settings on my iPhone in Lightroom mobile for the same images and created a preset. Now all of my shots from the iPhone look great on a computer screen using those settings. I use a 5k iMac. Once you apply the correct exposure to the scene you are about to shoot, the RAW image can then be properly edited.
As for a decent camera, I have that covered. Two Sony A7RIII 43mp camera bodies with Sony G Master lenses and Sigma Art lenses, plus studio strobes, reflectors, the whole nine yards. I can produce images just as good as any 12mp camera using my iPhone. I know there isn’t any aperture settings on the iPhone cameras nor does the iPhone produce the same bokeh as a $1700 lens due to the small sensor, but for landscape, cityscape, some portraits, & even natural light still-life, the iPhone holds its own. I know it’s limitations and shoot accordingly. I don’t add or put limits on the iPhone, it’s a powerful camera. For those that just casually shoot photos with any iPhone and don’t compose, or make sure the exposure is properly set might end up with a noisy image not worth using anywhere but social media. For those of us who are professional or well trained photographers like myself, can produce excellent results using an iPhone.
Here is the leaf image taken in ProRAW on the iPhone 12 Pro Max that was printed 16x20
