Edit in RAW not as good as the Jpeg

Photography Asked by Raphael Chioratto Gonçalves on May 9, 2021

I take most of my pictures on mobile, and I use mostly jpeg for the convenience, but I sometimes use RAW because of annoying whites blowout, bizarre clouds or unreal colors. For instance, my sunset pictures are terrible in jpeg.

But something is really annoying me and I can’t find the reason. I’m fairly decent in post-processing, but for some pictures I just can get in the RAW the same colors and whites balance as the jpeg, no matter how I edit. Any ideas on how to improve this?

In the example I attach, even though the jpeg is over-saturated, the colors on the sea are much more balanced, and the whites and mid-tones on the bottom-right are much better.

(Sorry the jpeg and raw labels should be the other way around!) raw Vs jpeg

This is likely due to the AI processing aspect of most phone cameras.

When a phone camera takes a photo its often (Especially on newer models) not as simple as taking a single sensor readout and processing it. They often are buffering frame the entire time the sensor and camera app are open, once you press the image button multiple exposures are taken (Unless you are in a pro mode where you have selected the shutter settings). The powerful processors in mobiles these days are also used to do a form of object & edge detection to do some 'Smart' sharpening around objects the phone thinks are the subject and they often have an option to add artificial bokeh (Defocus of background). Basically, a combination of complex algorithms are used to generate a standard out of Phone jpeg.

Whereas when you take a RAW photo on a mobile you are genuinely taking a single exposure from the sensor. You are limited with the data of that single frame to work with. A comment on why your RAW photo after processing looks different would be what software are you using, I’d imagine you could make these images basically look identical with enough editing especially of the HSL and cures in Lightroom.

It looks like a midtone/gamma issue to me... too much shadow recovery? I honestly believe a lot of people spend a lot of time just to gen a raw image up to the level of a SOOC jpeg...

I adjusted the gamma for the upper image and the exposures/colors are closer now. I would have to start with the original raw file to do much better.
