I want to take pictures of hundreds of Lego pieces with a white background. As a beginner in photography, I am using the first DSLR camera that I could get my hands on and I bought a light tent for proper lighting and a clean background.
Left: Exposure time: 1/6 – BG is white but torso appears too bright, Right: Exposure time: 1/13
Initially, I used a long exposure time to get a white background. The torso appears too bright, shown in the image on the left. Therefore I adjusted the shutter speed to get the image on the right.
Left: How I used the "curves" tool in my editing app ("Photos" on macOS), Right: Edited image (the right one from above using 1/13)
Then I edited the image such that the background appears white again. I used the "curves" tool and I think the result does not look too bad. Also, the colors on the torso appear more accurate.
But it feels a bit weird and complicated to do it that way. How should I go about it and should I make some changes regarding lighting, camera settings or post-processing?
Bonus Question: How can I make a white object stand out?

Some of the parts are white. When I take an image, the object blends into the background. I want to get a result similar to the image on the right (not mine). What can I adjust to get it right?
Camera / Lighting Settings
Left: Settings used for my images, Right: Foldio Smart Dome used for lighting/background.
With the Foldio Smart Dome I think I cannot light the subject and the background separately and the light is diffuse. I keep reading that it makes sense to light the subject and the background separately and I wonder whether my equipment is not ideal.
Side Notes: I bought this particular Smart Dome because later on I want to take 360 degree images. And I am shooting in RAW.
