I bought the setting tips and have worked through a few inside a convention center. My pictures do not turn out well. In the entrance to the convention center, still some natural lighting, or outside they are fine.
What lens/settings should be used for this (example, taking photos of Cosplay in Exhibit hall)? Link to Group for Denver Comic Con 2014. https://www.flickr.com/groups/denver_comic_con_2014/pool/
I have the Tamron 18-270mm VC f/3.5-6.3 and 28-75mm XR Di IF f/2.8 lenses.
