BTW, the chair is a perfect object for RC.
I am sure with enough images (crouch down!!) you could get an almost perfect model without any pp.
Make sure you are close enough and capture all the angles.
Use a flash if necessary for the dark corners - it is not as harmful as sometimes described, especially for projects where absolute measurements are not that important.
Do at least 3 circles of at least 16 images (more is better), try to get as much of the top as possible (without your feet) and get right in there under the seat.
It is a matter of trial and error and so learning.
I’m doing it off and on since 1.5 years now and far from knowing everything…
If it comforts you, my first project was a choir ruin 900 km (why make it simple) away and I had to go back there to re-take all the images.
First it was 2500 and then 6000 !
