100% this. I've taken enough photos at this point to know that mine are junk. It's definitely the hardest part of the whole undertaking. Taking the measurements like I did is pretty trivial once you have a great photo with something in it for scale.Good photos are crucial and very hard to take. I have failed many many times to achieve the accuracy this sort of project requires. I'm glad you gentlemen are on it and figuring it out.
I'm going to buy a USB Pluggable 2.0, but I'm pretty sure it's going to be a while before my pics are up to @Rosseforp's level.
