Issues with shadows and focus in antman dataset

[brotherofken]

First, thank you for creating and sharing this valuable dataset and code samples! I've been exploring it and noticed some issues with shadows and focus in some of the images.

Shadows: In a number of images, the photographer's shadow is cast on the object. This can create problems, for example, when estimating the environment map and material properties.

Focus: Some images have the object partially out of focus due to a shallow depth of field. This can affect texture estimation performance too.

Here is a table with some examples (click to expand).

While these issues may be challenging to fix, I hope this report helps others in debugging.
