Very interesting. I have yet to use DPP even though I have shot tons of Canon so did not know this. The result you get adding +40M as a preset is different from using a uniform color addition with the slider tool per your comment above? This little project was my first time doing this but looks like something to keep in mind for future UW color correction. My biggest issue, however, is stained water which I find very challenging to fix in a satisfactory way.

BTW I noticed that even within the normal slider range there can be some nasty artifacts, particularly with clarity.



Yes. The solution is to make a profile with a higher Tint starting point. This one was called 40T - as it adds an extra 40 units of Tint before you start using the Lightroom controls. 


String’s problem is that Canon cameras in particular can add more tint in camera (more than +150) than you can in Lightroom (limited to +150). DPP supports this in the Canon RAW file. Lightroom does not. It is why I always tell Canon shooters to use RAW + JPG when shooting filters. Or use this work around. 


You can also achieve a similar affect with the sliders in the Camera Calibration module - but I find them fiddly to use. The Custom profile solution is one click simple and it s stored in Lightroom for future use. The profiles are Camera specific.

I just remembered there is a way to increase the adjustment range. Insert and pull down the gradient tool all the way and select the change you want from the menu. I picked the color thing on the bottom and added a bunch of magenta. Not the exactly the same result as what Alex did but you should get the idea.

Here is a version of the turtle unprocessed and processed in Lightroom and only in Lightroom with a few clicks - (this is just a virtual copy of the original file):



So what exactly did you do? I gather something beyond the tint slider since it was already at the maximum setting.

I think you have reached the limited of what Adobe can do in color correction. I looked at some of my Hawaii pix. 150 is the max correction for tint - hit a wall as well when shooting though a lot of water and no flash. Most shots require less than 150. For example one was at +64 for a school of fish at a distance but with flash.

How many of your buddy's shots were back lit vs. front lit? Back lighting makes the backscatter worse. One option is to do macro photography. I remember back in the film days when the vis was only 5' (often in Alaska) - this was when the 1:1 framers came out to use with a Nikonos!
