Everyone must talk as much as they want to, that's the whole idea.
If you lean too far you'll fall over
But good idea. Let's see if we have a consensus - portraits, still life or maybe something else? But please bear in mind that nearly all of my own experience is with studio flash, I know relatively little about using flashguns indoors, so if we can have someone else there with a lot of experience with flashguns, such as @philV then it would help.
And I'm pretty disorganised, whenever I've done shoots for tutorials I've always meant to take stepback shots showing how I've lit the subject but have nearly always forgotten to actually do it, so have little to actually show
And I'm still thinking that it should basically be a Q & A session (not a lecture or training session) to keep it relevant and useful to as many people as possible, but tell me if you think that's the wrong approach.
And finally, I'm going to be stuck indoors for a long time, I don't care what the government says, I'm an insulin dependant diabetic, I'm old and at high risk of Coronavirus and I'm going to do the world a favour and keep away from other people, so anyone who has specific questions about lighting and who doesn't want a public discussion about it on this forum is free to contact me via PM, I have the time. I also believe that people who have enjoyed photography and done well from it should give something back.
Picking up on a specific lighting challenge that was raised last time, someone asked about controlling reflections in a specific situation. The challenge was to photography a perspex safety shield for minicabs, installed behind the driver. I gave what I hope were useful pointers, here's a more comprehensive answer.
1. Assuming that the main shot is taken from outside the car looking in, first wind down the windows on that side of the car, to ensure that there are no reflections from the windows.
2. Walk around the car, look through the viewfinder and adjust position so that the reflections from the perspex screen are minimalised.
3. Put the camera on a tripod, wind the windows back up and take a shot, which will be used later.
4. Put the windows down again.
5. Fit a polariser to the camera lens, adjust until reflections from the perspex screen are minimalised.
6. Place a flashgun on the other side of the perspex screen to light the inside of the car to a higher level than the ambient light, making sure that no light directly hits the screen. This works in the same way and for the same reason that people can see through lace curtains to spy on their neighbours without being seen when it's brighter outside than inside, but they can be seen clearly at night when the inside is brighter than the outside.
7. Blend in the first shot (step 3) and adjust to suit, so that the windows in the final shot are closed and showing just enough to make it look genuine.
That's it.
