These HDRi can be used in any 3D program (3ds Max, Maya, C4, etc).
These are the panoramic HDRi spherical type and 180ºx360º.
Time that they made the photos 6:55
By bringing together images to create a dynamic range HDRi 8,83EV get real.
Background images in JPG format (color: sRGB, 8 bits).
Background images were made on the same date and time the hdri.

WHY IS AN HDR HIGH RESOLUTION AND OTHER LOW RESOLUTION OF THE SAME HDRI?
The low resolution HDRi is to optimize load HDRi on the scene if only used as lighting. The HDRi used to illuminate a 3D scene; for reflections and the background scene. If it’s just to light, it is not necessary to load a high resolution HDRi because it consumes memory only just one of 1024×512 pixel and the same quality of light you get with one of great resolution. However, for reflections and background if a high resolution HDRi necessary.
By reducing the resolution (dimensions) of a HDRi with Photoshop or any image editing program, sometimes HDRi loses some of its dynamic range so that it retains the dynamic range has to be generated from the image sequence capture original, which is why I included a low resolution HDRi generated from the original, thus maintaining its real dynamic range.
Place the HDR in the materials section as Spherical map type. Depending on the rendering engine horizontal or vertical rotation of HDR can be as Offset U / V (0 to 100) or rotation H / V (0° to 360°).

DYNAMIC RANGE CHECKING IN PHOTOSHOP
Open HDR with Photoshop, in the bottom left you will find a scroll bar, move the center indicator to the left to see underexposure and overexposure to the right of the HDR. The visual appearance of HDR in Photoshop does not affect the lighting within the scene.
