I am not sure about the “blacks for trump” photo, but the second photo, in front of the Trump-Pence airplane - the lighting seems virtually impossible - quite bright and coming from the camera angle and quite bright for persons on both left and right - but almost non-existent on his person and his sign.
I wish I had my other computer now, with the proper software to look at these pictures pixel by pixel, and study the jpeg rendering in different regions.
I believe several of those DailyMail photos have him inserted into them.
