Yep, being constructive isn't my strongest point, you got me there
I'll try to explain myself later on today, I need to check the parameters of the lightbox I'm using (it's stationed in my family company's building, I never really bothered with the parametres as long as it gave effects
). I didn't see this discussion before, I was being busy with putting a photo-review on my site, not to mention two more on collectiondx and putting together one Microman for my YT
But to explain myself without the tiny little details, Flash is baad because it's a single blast of intense white light which has the most power in the center of your picture (where there's more light than needed so you get white reflections on the toy) and it slowly fades away as it goes further, so sides of your photo might be underlighted. And, it often disturbs color balance. That's why well distributed and constantly present lights gives better effects.
It's a rather failed experiment, but I tried to use some black shiny paper from Ikea to attempt making dark backgrounds myself. Never use that thin kind of rolled paper they offer, it won't just get flat and smooth as you wish, no matter how much you iron it
