Where the former is a one-click approach with very few settings, the latter offers fine control over every step in the photogrammetry process. But if you start every step in the workflow above manually, you will lose a lot of time when process has finished and you need to start the next one yourself. By creating a Batch, you can pre-define all steps you want PhotoScan to take and the settings it need to use for each step.
These are just a few actions you can add to the Batch. Guess that takes some experience to do educated guesses. Expert Tip: Chunks Photogrammetry, and 3D reconstruction in general, is a very computer intensive task. For instance, the amount of photos you can process depends largely on the amount of RAM in your machine.
Basically, you make logical groups of photos that cover a certain continuous area of the object or environment. Then you process that part like I did in this review. And when all Chunks are meshed, you can align them and fuse everything into one single object that you can export.
They will probably not be the favorite thing to display on light systems and are certainly not optimized for tablets and smartphones. There were no issues with processing the photos from this setup. I did an Ultra High version in the next section.
Interestingly, PhotoScan was unable to distill the details on the very top of the head of the bust, even with all modes set to their highest accuracy. But the amount of photos is 9 instead of 16 with the turntable. Also, ReMake had no problem with the top of the head with this amount of photos. I made no additional down-facing photos. That can than be used to make a shader for a low-poly version.
The vintage camera below actually has an interesting bottom plate. I did this tuning the lights and camera exposure until the background was totally white. This way I could keep the camera in the same location and rotate the object between cycles. And it worked! The only editing I did was adjust the exposure levels of the texture in Photoshop to compensate for the over-exposed photos. The viewfinder on top is even glossy black and apart from some geometric noise that did come out very well.
Also nice it that the levers on the lens, which are really tiny, rendered beautifully. I used a monopod and controlled my Sony RXM2 And while ReMake had no problems with that , PhotoScan again had issues with the very low amount of photos from the top highlighted which resulted in a hole in the model.
The Hole Filling algorithm did close the hole but with very few polys. And unlike ReMake, PhotoScan has no option of subdividing selected polygons to create a polygon density that better matches the rest of the model.

Even with the highest setting I was surprised by how fast the meshing is performed. Texturing The resulting mesh has color information but at this stage this is stored as per-vertex color information within the 3D surface.
Depending on the polycount the level of detail can already be quite good but if you want to get the best color quality you can generate a separate UV texture map. You can click the images below for the full-res textures. But I really like that PhotoScan generates big UV islands instead of a gazillion of small ones that some other programs come up with. If you put your mind to it, you can simply edit these in Photoshop. Advanced Mesh and Texture Editing After mesh generation, PhotoScan has a build-in tool for decimation as wel as a Gradual Selection Tool to quickly select and delete small meshed parts that are not connected to the main object.
Unlike ReMake, PhotoScan cannot decimate a mesh and generate normal or displacement maps from the high-poly version. Photoscan also has no sculpt tool like ReMake. However, the upside is that unlike ReMake, PhotoScan allows you to export the mesh, edit it externally, and re-import it.
This way you can control the retopology in a program of choice like zBrush but still use PhotoScan to generate a high-resolution texture. When doing this, PhotoScan can preserve the UV layout generated by the external program. PhotoScan cannot decimate a mesh and generate normal or displacement maps from the high-poly version. Thanks to everyone that reminded me of this! In fact, it was a perfect test of the permanent Photogrammetry setup I made in my office. PhotoScan performs best with a more professional studio setup and more ideal shooting circumstances.
