Diving to 130 was not a problem but operating a camera and DSLR photography needed decisions that were taking a lot of mental effort.
That was because the diving was going as planned, had it gone south, you would find that dealing with an emergency could have been as challenging as operating the camera.
Narcosis will make a diver slow, stupid, and less situationally aware without knowing it until something goes wrong. Whenever I dive deep air and have not been doing it regularly, I make progressively deeper work-up dives and find out if I'm ready and that I can manage the narcosis on the dives. This doesn't insure the success of the deep dive, but if you have problems sticking to your dive plan and don't abort immediately, you wont fare better deeper. As focus is narrowed by narcosis, the limits of depth, air, and time are necessary, if any limit is met or forgotten, one has go up to a depth where it can be sorted out, because one way too narked.
Whenever I dive deep, I have a mild paranoia and if it is not there I abort. If I have a dark nark or a happy/peaceful nark or hear the Sirens song, I abort. If anything does not go the way I planned, I abort. A bit of advise I got from and old diver back in the day, One can manage narcosis to a point, the only way to stop the nark is to head up, if you don't, good luck, you'll need it.
I've been deeper than some and not as deep as others.
