HDR (high dynamic range) is well known in digital stills and HD DSLR. Some proprietary programs such as GingerHDR even give you 'natural' looking footage after render. Well I have been reading up on ETTR or Expose To The Right for shooting in RAW files. Seems that this technique helps in bring out the details in tricky low light situations by slightly over exposing the raw not to the point of clipping the highlights.
Here is a much more detailed and knowledgeable explanation from an expert in this area:- http://schewephoto.com/ETTR/
Here are just a sample of the discussion in ML forum : http://www.magiclant...g31285#msg31285
Just to highlight the pluses:
I believe there is merit in finding out more on this technique for UW footage since we encounter some very tricky lighting situations near surface or shallow depth and also lost of warm colours as one dives deeper. Recovery using ETTR by using the histogram to expose just before highlight clipping seems to work well with stills. I also read in ML crowd that this technique could be applied to raw video footage and has this feature in ML firmware. Wonder if anyone has experienced with this?
