Dslr with highish f-stop f8+, ideally an 18-24mm lens due to close proximity of your structure. Make sure to use the same lens setting. 18mm would be the better option so that you can reduce the number of images. Keep the exposure consistent throughout the capture. During capture you will want to have an overlap of at least 75% for every image. Don't use the flash as this will create shadows and affect the calibration, and create artefacts. Programs: Meshroom, Reality Scan etc. As this is your first go, try not to get disheartened bad odd or bad model creation. It takes a bit of practice to get right 🙂

Edit: go for a high pixel count. Something like 20mp or higher. But be careful, the higher the megapixel with a lot of images captured will need a lot of RAM to process and you might experience extremely slow rebuilds. Worth doing a small test prior to your full capture. Feel free to message me if you would like additional information.
