I plan to shoot an object (a banana peel to be precise) and then replace the background with another image (1). What would be the most effective approach given the following conditions:
- Canon 550D
- Sigma 18-55mm f/2.8-4.5
- Maximum camera to subject distance: 1.5m
- Distance from object to wall: around 0.5m
- No flash, but continuous household lighting (2)
- I have a black cardboard backdrop of 1x0.6m. It's not a requirement to use it.
- The background should be able to be replaced automatically. There will be a lot of photos (it will be a stop-motion), so I can't manually mask every single one.
(1): The full story for those interested, (I think) this is not relevant to the question: I want to make a stop-motion featuring a banana peel as a person. I can place the peel in different positions and hold it with transparent thin fishing lines. However, I would also like to animate the background. Doing this simultaneously with the banana animation is tedious. My plan is to do a stop-motion of the background separately and then replace the banana background through some keying process.
(2): I do have an off-camera flash, but no way of syncing it. If I hook it up to my DSLR it would probably fry it as it is an old 300V flash. Household lights range from 10 to 150W.
