Thank you for the reply,
I did not know about grey ball but I kinda guessed why it was used.
I am aware that the chrome ball is for the HDR image capture, I was just mentioning the steps, but I was wondering why they needed 3 cameras? Did they use the 3 cameras to take simultaneous pictures or their was 3 people, so 3 camera for each?
Yes my 450d gave good result but I am aiming for great. The project that I am working on is more of a graphics demonstration, that is why I need to get the best 3d scans possible. What camera would you expect to give the best results without going overboard with the price? And what lens would be the best? Also note that I might attach this camera to a drone to scan large structures, or extract DEM Data.
Anyway, what really I would like to know is how were they able to manipulate the scans? Because 3ds max was not able to handle them. How can cap a rock for example? join scans?
And how can I get my hands on the TIFF16 editor (the one that replicates the work of the brighter image on the darker one)? because I doubt they will release it.
