Just had a bit of a thought and guessed you guys would be the best to run it past!

If I had a series of images in the correct format for HDRI's (24 bit Tif's I think would do??) could I use the Spherise tool in photoshop to create a basic light probe image, and then use the HDR shop software to compose the differently exposed images in to one hdr image??

I might be barking up the wrong tree but I just had a bit of a think about trying to create HDRI's in the most simple way so any comments would be great.

Cheers
