Fluorescent intensity ratio of two channels across area of a cell-depth encoding

Hi everyone; still rather new to fiji, therefore hope you can share w me your knowledge.
my goal is to measure if the subcellular localisation of protein 1 is affected by protein 2 within the area of a cell
therefore i was wondering if there’s a plugin/ tool which measures fluorescent intensity of protein 1 within my cell as compared to protein 2 (another channel)
I know there’s tool such as line graphs etc. but what we preferably would like to use
is some sort of fluorescent intensity depth encoding across the cell area(as our images are z-stacks).
would hope to seek some advice/ good suggestions from you guys!
many thanks!
