About an issue - Something went wrong

[Nightingale]

Hi everyone,

I made other tests.
Everything black in the photo booth.
I added lights under the bust to avoid shadows.
With f/11, ISO100, exposure time 4 sec, here is what I get.

What do you think about ?

Thanks

I made another one with 8% of light from the ceiling (instead 2%), and exposure time back to 2 sec. I think it's better: we have less noise.

Hi nono_sax,

it's hard to tell from one image alone, however:

- if you're moving the subject, make sure to mask the background
- try having better lighting in your scene, as moving shadows will make the scene harder, especially when dealing with uniform surfaces
- uniform surfaces such plastic are hard to capture due to light shining and lack of features: if this is your first experience with photogrammetry, i suggest starting with something easier. This subject can be done but requires a good understanding on how you need to set your camera and lights to get good images. You may need a lot of overlap as well, due to the lack of feature.

you can share the dataset with us at support@3dflow.net if you'd like more specific details.
