Have you tried ND polarized filters? DJI has their own as well as Pgytech and Freewell. Might have to start out with the lower number filters like 8 and when it's sunny out move up to 32 or 64. Plenty of YT video on how dramatic a difference it makes.
A ND filter won't help, it will uniformly reduce the amount of light hitting the sensor. He will need to increase the ISO value or use a slower shutter speed to maintain the same brightness as without the ND filter, but the problem of the extreme contrast between shadows and highlights will remain.
When no RAW recording format is available, once the luminance levels clip, information is lost and can't be recovered. In situations like this, I would use manual image controls in combination with zebras or a histogram to monitor clipping. Make the image as bright as possible without blowing out the highlights, and then lift the mid-tones in your video editor as needed. I would probably leave the shadows alone since these would most likely just be the black wetsuits, and there is no point in making them look gray. |
