hello. i am old in professional photography. but i am very new in vr tour. i have organized only 3, 4 tours. there are one or two issues. the camera i use is ricoh theta z1. this camera is very good at doing the job fast. but it gives excessive noise in insufficient light situations. i enlarge the size of the photo with luminar. and i recover the noises a little. but it still does not offer the quality of an average camera. i bought a panaroma ninja head. i have a nikon crop and full frame camera. i also have a crop and full frame camera for sony. what do you recommend for quality photography. can we use external light when shooting with z1. so this is the subject that is a little bit challenging me. i would be very happy if you help me. thanks a lot.
