Thanks!
I have a 6500k LED spot that produces a light that is both strong and pleasant to the eye, and combined with some diffused sunlight, it's enough to make decent pictures. By the way, these are iPhone images - inside a terrarium, it's more convient to use and I can shoot from otherwise awkward angles.
Regarding N. mollis, you may like this photo I made with my DSLR, using focus stacking to get more depth of field: https://carnivorousplantstories.com/wp-content/uploads/2020/02/1-23-02-2020-Nepenthes-mollis-hurrelliana.jpg
