Thanks for the info so far, any facility for colour correction for underwater photos? The white balance can be corrected (and there are niche products to automate this) but it would be good to have an all-in-one editor.

Way too low - those levels appear to have been set low due to a statistical error. I take 4000 IUs daily, partly due to night shift work but also because there are nearly 200 studies now linking Vit D deficiency to worse Covid outcomes.
