I plan to shoot an object (a banana peel to be precise) and then replace the background with another image¹. 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 lighting²
- 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.
