My journey into Blender 3D started about a year ago. For me this was a tool looking for a problem. Admittedly the skill build up took a while, but every step counts, like when you are trying to assemble a jigsaw. Yesterday was the day that I had a go at modeling a beverage can. This seems simple enough but it took a bit of a run up before I could produce a useful model. One reason why I bother is that 3D has a potential value in the somewhat related field of product photography, which I also happen to practice.
Here are some initial, two rendered cans, and an earlier example of typical product photography without rendering.
In theory the huge win from 3D is that you can get creative with composition as if you were at the shooting table, but much faster, less messy, and with far greater consistency.
