Post processing adjustments help

[PDR]

I am trying to take some ok pictures of some coral I would like to sell. I only have an iPhone X but I do have the old aperture program. I have been messing around with the settings trying to get the colors closer to what they actually look like and I was wondering if there were certain settings I should avoid messing with.

So far I have had the best results only adjusting: white balance, exposure, saturation, and sometimes black point and brightness depending on the pic.

Are there any settings I should be adjusting in addition to those, or any I shouldn't be messing with?

I'm really new to this side of things, so assume I know nothing lol

Thanks!

Here's a bump for some photography experts out there:D

I try to adjust as little.as possible. Usually white balance, exposure, blacks, shadows, whites and highlights is all I do. I'm far from an expert though.

A little bit of sharpening sometimes helps. Don't overdo it as itll make picture look noisy
