About the Image(s)

I was inspired by some of the landscapes posted by other people in the group, and decided to take a shot (sorry, bad pun) at working with HDR. I've been vacationing in NH, a state known for its historical covered bridges. They are all numbered to make them easier to find, and a popular subject for photographers.

A covered bridge was a good subject to learn HDR, it seemed to me, because you have the bright sky, the bridge itself, the shadow under the bridge with all the lovely trestle detail that one wants to see, and the "light at the end of the tunnel" that gets blown out in regular fotos. So I took pictures of a few of them.

This bridge is the very first one I photographed, Bridge #65-Squam, late in the afternoon, using a tripod. (More on this bridge here: https://www.nh.gov/nhdhr/bridges/p109.html)
I include the HDR combination the camera did, and then the combination I did in Photoshop (I made some slider adjustments in ACR). I knew absolutely nothing about this, just followed steps described in this article: https://helpx.adobe.com/photoshop/using/high-dynamic-range-images.html

Gear: Canon 5D Mark III, EF 16-35mm,f4L IS USM
Shot Info: Focal length 29mm; Exposure 1/12 sec; f4.0; ISO 400; Aperture priority; spot metering

These are (nearly) always interesting subjects. The "original" appears to have more detail than the "final" version but to my eye shows an unnatural lack of shadow. The "final" is still too dark under the roof IMHO. I have tweaked the "final" in LR increasing shadow detail by +50 which to me looks better.
To be honest I tend to use the Photomerge HDR facility in LR and it works reasonably painlessly.   Posted: 08/12/2019 03:26:21

Dear Andrew, thanks for the tips. I photographed several bridges during my vacation so I will try that technique as I refine other images.   Posted: 08/12/2019 06:07:47

Looking at the picture a second time, it strikes me that there isn't really an upright vertical or un-tilted horizontal line. The bridge roadway and the roof board line at the entrance slope in different directions. The right hand upright is about OK but the left hand side is definitely wonky. This may reflect the fact its a man-made structure although it's only 1990. You have also cropped the apex off the roof. I am not sure you can do very much about this in post but it somewhat detracts as an architectural record shot. Do you have any other shots taken at a wider angle?   Posted: 08/17/2019 05:27:22
