Here I thought I was future proofed with my tidy collection of 100mm ND Grads and colored plates from Lee and Formatt HiTech... Alas no, for my new-to-me Caltar 360mm is a dastardly 112mm thread.
Would it be absurd to hold a 100mm colored filter in front of the lens during exposure? Or do people attach rear mounted Lee adapters? It would be something of a tight fit... But with threaded filters well into the triple digits here I just thought I'd ask for some solutions.
