Optimum/Max/Min Relative Humidity?
Hi there. Something weird seems to be happening to my digicabi dry cabinet.
When turning the knob to the minimum setting all the way left, the RH shows as ard 48%, and when turning it all the way right, it becomes ard 42%. is such a small variance common? i am using a digital hygrometer so the chances of it being spoilt should presumably be lesser.
Second, just want to ask whether it makes a difference whether the RH is too low. we all know the optimum is 45-55%, and i assume that anything higher results in risk of fungus appearing. however if i set the RH below 45% is there any adverse effects to:
1. Camera Equipment
2. Camera Lenses
3. Negatives stored in the dry cabinet.
