Quote - Sort of off topic but not really.  Finished my first ibl with vue last night.  This was a full (yet small and basic) scene.  Saved it out with 4000x2000 jpg, exr and hdr.  The quality of the picture itself wasn't what I was hoping.  It was a tad washed out when I put the jpg on the reality ibl sphere.  The upside was that it rendered really nice.  I was getting double the speed from this light than I have out of other ibl's I've used.  All three files together come to about 90mb in a rar file; so, I'm not really sure where to put it to enable others to download it.  Anyway.. here's the render I created using it....

 

What background???     The lighting is great, makes her skin pop...  But then again, she's popping anyway you want to look at it.  hehe!

You might try taking that BG image into PS/Gimp and increase the contrast but that will also change the light value as well. Or you could just post in the BG.
