Since when can Photoshop not handle 32 bit tiffs??????!!!!!! I use them all the time in Photoshop (and yes, you can completely avoid the HDR conversion by handling in Lightroom first, which PS then does NOT want to HDR convert).
DSS also exports as 32 bit rational or integer tiffs, so saying it does not is again wrong.
Pixinsight is good, but EXTREMELLY non-intuitive, with VERY little help regarding what each function does. Not as poor as MaxIM though.
I am not seeing the benefits of Pixinsight yet. Everything with few exceptions can be run through Photoshop, especially if you use the multitude of Photoshop plugins (like gradient removal, White Balancer, Green removal, star masking, DPP, etc). It's ALL there for Photoshop, you just have to look.
Personally, I find the Australian made Startools stand-alone software superior to Pixinsight (expecially intuitively and with help/documentation/instant drop down guidance), though Startools could do with a little updating. And it is also a quarter the cost of Pixinsight.
