manually instead of letting Samantha estimate them, you can. After the cameras have been aligned, you can proceed and extract a dense reconstruction. The process requires the input cameras to be correct. If you believe a camera is not correctly aligned, you can remove it from the workspace. Before proceeding you can also restrict or expand the volume of reconstruction. The reconstruction process is powered by Stasia, our Multi-View Stereo technology. You can create different dense reconstructions (with varying parameters) and save them into the workspace. Starting from a dense reconstruction, you can create a triangular mesh. Basing on what you are going to reconstruct you can choose among the generation of a smoothed surface (when dealing with human body or terrains for instance) or the generation of a sharp surface that more fits scene such as buildings or mechanical parts. The latter kind of surfaces are handled by Sasha, the latest algorithm developed by 3Dflow. Every mesh polygon get textured with pictures zone where it is detected. Within texture generation phase there is a color balance algorithm as well, that allows to select and set-up the best color for each pixel automatically by checking the different lighting changes on the photos. In the next section we will give some hints and tips on how to take the right photos. Photography Guide In this section we will list some tips to obtain good reconstructions. 3DF Zephyr is completely automatic but does require some forethought to produce the best results. Camera sensors. What you'd better keep in mind when picking your gear:  camera performance is not given by its megapixels resolution;  high-end cameras do not always lead to better result; A good camera must allow a full light management in order to control each exposition value. That's why DSLR cameras (reflex) are usually recommended even if both mirrorless cameras and bridge cameras can fulfill that need. Camera sensor is the real highlight of the matter and the following hints could be quite helpful:
