I streamline the work done in that tutorial.

In Adobe Bridge select the images required, (having turned off any auto adjustment ACR is making to your images if you have this option checked to start with.)

go to Tools/Photoshop/ Merge to HDR

Sit back and watch as PS works out your cameras response curve and jumps straight through to the preview HDR stage.  You then have the option to check or uncheck chosen images to alter the result. Like the tutorial I found the best results were from around 6 frames with a +/- 2EV difference between each one.

By all means do some adjustment to your HDR conversion but I think it is better to use adjustment layers after the conversion to 16bit Tiff than to try and get it spot on at the conversion stage. You can also embed the RAW as a smart object at the Tiff stage if you want to make any final tweaks using the RAW file/files.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
