This is among the best Panorama tools I tried so far. I like the good default stitching, batch mode, great blending and fine tuning capabilities.
It is not yet the perfect tool for me however: I would like to stitch panoramas in scene-referred, i.e. have the ability to export DNG files instead of standard TIFF. I would also like to adjust the preview exposure while reviewing the panorama, so I can better see issues in highlights shadows. This is my only reason to not give 5 stars.
In addition, the fine tuning is pretty cumbersome right now. I have a couple of ideas of how this could be improved. Are you hiring? I might be able to help with both improvement opportunities.
