I have been using the office at the hangar as a testing studio. The reason is that it is air conditioned and there is a nice steady fluorescent ceiling light. I needed to have target, and a bottle of Glenmorangie Lasanta was available (we do have good taste in liquor.) My intention in the whole thing was to compare two iPhones and three cameras to check out sharpness and noise at different focal lengths and ISO settings. For the iPhones (7 Plus and 12 Pro Max) I was using the camera feature in Lightroom Mobile because you can control the camera where you can't with the native iPhone camera app. What I could observe was pretty much as you might expect. Unfortunately, I couldn't get control of the 12 Pro Max completely with Lightroom mobile. I am going to repeat these experiments when my new Powershot G5 X Mark II arrives.
