6 HDRI (.HDR) files that were created in "low" def and converted to high def with Photoshop CS.
While these should load into any app that supports HDRI/IBL I haven't tested these in any other app but Bryce.
To load these files in Bryce 6.1 (only!):
Open the Sky Lab and select the IBL tab
Click the Use HDRI Image button
Select the .HDR file from the Open selector
As a starting point, set the values shown.
Mac users: These files won't load if you have Imported an object (i.e. .OBJ, .3DS, ect.) from the File>Import Object... menu item. This can be worked around by loading the HDRI in an empty scene and merging it with the object scene.
Free for use in any image but the files themselves can not be re-distributed in any form without permission.
