During the lockdown I did a lot of macro photography. Many people were asking about setups and other tech details, so I thought I write something up in my Services > How-To section on my website (here a direct link to the relating article, though there are a couple more if you're interested).
Here a final image and the actual setup behind it:
Canon 5d Mark 3, Canon EF 50 mm F1.8 lens, 13 mm extension tube and 31 mm extension tube (those are needed to get closer to the subject).
Background is a black umbrella on tripod, object and camera mounted on tripods, construction light on another tripod as a light source, RC remote for the camera, camera connected to PC to get a better view on what it actually sees (you see the screens in the background of the first BTS image).
I shot the scene with an aperture of F2.8, which results in a shallow depth of field (the soft effect around all not-in-focus parts of the image).
The blue-isch tint id not editing. It's one of the standard white balance settings in the camera, called <tungsten>. This is like using a tungsten based film in the older days.
