  1. Hi everyone, I've been looking at ways to store all of my photogrammetric models and the image data sets that go along with them. I'm trying to figure out the best way to package it all together and am curious how others are storing these often large file sets. Anyone willing to share their methods? Thank you

    tiny objects

    Hello there! I've been working with a very small mammal skull (a tenrec) and can't seem to get it right in that the top and bottom are not recognized in one single chunk in Agisoft. I can only get the photos to align in separate chunks, which is a huge headache. I've been using a turntable, diffuse lighting, tripod, remote shutter, changed the background after flipping the skull over and masked everything. I suspect it's my photos that are causing the problem...and I might need a bit more light, (the lab I was in was a bit dark). The size of the skull is about 1.25 inches in length, 1/2 inches in height, and 1/4 - 3/8 inches in width. Should I shoot one circuit at 50mm and another at 24mm? This first attempt was with a Canon T3i with a standard lens set at 24mm. Camera settings were ISO at 200, F7.1, shutter speed 1/80. Does anyone have any advice on shooting something this small? Thank you in advance for your help!

    flat run question

    Thank you for the advice! I'll try it.
  4. Hello, I have a few small objects I've been working on and have run into an issue with alignment. Sometimes only one of the two camera groups will align and other times they both align, but top and bottom are not recognized and I end up getting a mess. The objects in question are flat bone tools and I thought they would work better shot as flat runs rather than as circuits on a turntable as they are too fragile to stand on end. They're about 7 inches long and 1/2 inch wide at the widest and tapers down to a point. I suspect my issues lie with the set up. My question is, do I need to change the background (what the object is lying on) when shooting each side (top and bottom)? And since I'm moving around the object, I would not need to mask it right? Thank you
