Shelby Tombstone by Abby Crawford on Sketchfab

Here it is run through Agisoft Standard (without any masking).

Alignment Settings: Medium accuracy, pair preselection generic

Dense Cloud Settings: High quality

Mesh Settings: Arbitrary surface type, dense cloud sourced, face count high

Texture Settings: Generic mapping, Mosaic blending, 4096x1 texture size/count

In Sketchfab I tweaked the display settings a bit - Field of view 30 degrees, Shadeless shading, 13% sharpness, Vignette (47.5, 72.5), and Bilinear texture filtering

There was some noise near the top of the tombstone that I manually removed with varying levels of accuracy. I think the noise was the fault of my photographing. It ended up a little patchy. Otherwise I think it turned out pretty sharp.
