In the April edition of Photoshop User magazine, which was focused on
an editorial theme I am not particularly intrested in, wedding
photography, I found in the "Product Review" section, a review on
Unified Color's "HDR Express 3".
HDR Express 3 is a trimmed version of their top of the line "HDR Expose
3" and the review was enough to bait me into visiting their web site.

To cut to the chase, I have dowloaded the 30 day trial. It installs as
a stand-alone, and PS, & LR plug-ins. I have run a few tests of some
old 5 exposure bracket sets, and I am impressed.
I deliberately picked sets which had major ghosting issues due to
movement of people in the background. This was an issue neither NIK HDR
Efex Pro 2, nor PS HDR Pro have not been able to solve completely. HDR
Express dealt with the ghost movement & image alignment easily.

Then for those not favoring the surreal look of much HDR rendering this
seems to aim at producing realistically rendered images, and does so
quite succesfully.

They have a fair number of video tutorials available and I think this
is going to be my future go-to HDR tool

Just as another image processing tool to play with, give the trial a test.

Here is the result for my set with the ghosting problem, shared with
Adobe CC & DB sharing;

...and here is another 5 exposure HDR with a ghosting issue, namely the
folks walking on the pier, and birds.

Those are all darned good shots and I wouldn't have known they were
HDR unless you told me.


Thanks for that. I was primarily checking to see how HDR Express 3
dealt with ghosts, and reasonably "natural" appearing images. Both of
those sets were good for checking that.

Can you tell us the magnitude of the dynamic range (stops) covered by
the images that were used to make the final HDR?


The Bugatti was shot at ISO 400, the aperture was a constant f/5.0 and
the exposure bracket was controlled by shutter speed:
1/1250; 1/2000; 1/800; 1/500; & 1/320.
This effectively gave me a -2: -1: 0: +1: +2 EV exposure bracket,
basically a 4 stop range. I could have adjusted that upward by going to
a 7, or 9 shot bracket.

The "Shillelagh" was shot at ISO 200 @ f/10.0.
1/640; 1/320; 1/160; 1/80; & 1/40.

I suppose if I upgraded my D300S to a D7200, or a D750 I wouldn't have
to bother fooling with HDR.
