Photoshop: Can't create an HDR of 11 images

I spent a long time with support over the phone an after they were unable to solve the problem, suggested I contact you using this method. I was trying to merge 11 photos into a HDR using lightroom first, exported to Photoshop. I'm using the latest version of both software (creative cloud subscriber). Every time I exported the files the furthest I will go in the process was to the window were I see all the images thumbnails and I'm giving the option of toning the image in ACR. After I click to proceed the toning in ACR the window disappears and nothing happens after that. Photoshop remains open and funtioning but no process done after that. Support asked me to do just 2 images instead of 11 and the proces went smooth and I was able to create an HDR. Then we tried the 11 files and they witness the unresponsiveness of the software. Very soon he started to ask about the specs of my computer wich until now has been able to handle these files perfectly using other HDR software. To proof my point (support was assisting me via remote assistance) I created an HDR using the same files with Nik HDR Efex Pro 2 and the image was created sucesfully. He advised to contact this level of support to request further help.

I'm a professsional architectural photographer who creates HDR images all the time using either Photomatix or HDR Efex Pro 2 and never encounter problems. I decided to give Photoshop a try on this task with complete disapoinment. The computer used is a iMac 27" 3.2 GHz Intel Core i3, 12 GB RAM, SSD Hard Drive, 512GB video card and running OSX 10.9.5. The files I'm working on are RAW from a Nikon D800. I know I'm asking a lot to the hardware but if the other HDR solutions can do it, why is Photoshop limited to just a few photos?

Are the pixel dimensions of the HDR result the same as 1 LDR image, or is this an HDR panorama with dimensions larger than one image?

I'd suspect something is running out of memory. Try adjusting the amount of memory allocated to Photoshop - in PS / Prefs / Performance up to the highest amount you can, and see if the HDR works, and if not, then allocate quite a but LESS memory to PS and see if the HDR works. What I'm not sure about is whether ACR uses the memory allocated to PS or if it uses memory outside of PS's allocation, where allocating PS less would allow ACR to use more.

I believe one thing that is different between using an third-party HDR application and PS, itself, is that PS will render the raw files in memory as it is building the HDR while the third-party tools will be reading the results of the LR conversion off of disk which likely uses less memory.

You could try rendering all your HDR frames to disk as 16-bit TIFs and have PS build the HDR from those, rather directly from LR, and see if that makes a difference.

Have you used TaskMonitor to check the memory usage of PS during the building and attempted toning of the HDR image, to see if it is using excessive memory?

Could you post the 11 images you're are trying to merge (Creative Cloud or Dropbox) so we can troubleshoot using your files?
