Originally posted by BruceBanner Excellent. I'd love a BTS shot! I'm confused at the 'Pure white background done in-camera', what do you mean by this? I take it no flash use otherwise there would be shadows, so was this just taken in one of those soft light boxes for product photography? How are you focus stacking? What equipment and methodology are you using?

Thanks. The trick is to get the subject in the air and not place it down.
It's a two LED light setup with softboxes. One is the background and one is angled from the upper left (see the reflection on the top of the screw). The table is just a white surface which reflects on the bottom of the screw. Scrims between the softbox and the subject control the hardness of the light by adjusting the distance and angle.
In Live View I turn up the background light just until the blinkies start indicating over-exposure. That's where it turns to pure white without giving flare. Adjust the top light to taste until it looks good in brightness. That's basically all.
For focus stacking I tethered to IT2 and DCU because I'm lazy. Start at the closest focussing point and then, in IT2, hit the focussing button 30 times between each shot to move the focus forward.
I merged them in Affinity Photo. I let the app align the shots automatically (focus breathing makes the subject shrink when moving focus). Masking the focus areas wasn't hard since it is a simple shape. In complex shots the app can do it automatically but that didn't work here. Maybe not enough texture.
