High dynamic range on smartphones
Recording in log gives you a higher range to play with in post, so if your phone supports it, you should do it. If the phone is locked down for specific shots, you can try to film one pass of the shot with low brightness, crushing some dark areas, a normal pass, and a bright pass, overexposing the highlights a bit. If you now stitch those passes together, you should be able to see an improvement in Dynamic Range.
