Chain Bridge – ppw – 01.tif
- Artificial +4EV exposure, created in Adobe Camera RAW
- Exposure value: +4EV
- Shutter speed equivalent: 100s
Chain Bridge – ppw – 02.tif
- Original source exposure
- Exposure value: +2EV
- Shutter speed: 25s
Chain Bridge – ppw – 03.tif
- Original source exposure
- Exposure value: 0EV
- Shutter speed: 6s
Chain Bridge – ppw – 04.tif
- Original source exposure
- Exposure value: -2EV
- Shutter speed: 1.6s
Chain Bridge – ppw – 05.tif
- Artificial -4EV exposure, created in Adobe Camera RAW
- Exposure value: -4EV
- Shutter speed equivalent: 0.4s
Processing Information
The images have been pre-processed in the following way: The original three RAW files where converted to TIFFs in Adobe Camera RAW with the default settings.
The CA (Chromatic Aberration) was removed (see Correcting Chromatic Aberration for details). Therefore, you should turn off CA reduction in your HDR software. Alignment is also not necessary as the images are already aligned.
Two additional exposures with -4EV and +4EV were created in Abode Camera RAW to cover the widest possible dynamic range (see Creating 32-bit HDRs the Right Way for details).
The images where saves as TIFFs and watermarked in Photoshop.
No noise reduction or any additional processing was applied.
Processing Tips
Use the source images as you feel appropriate. It is not strictly necessary to use all of them. Visit the photo page at to get information of my personal workflow for this image. It may serve as a starting point.

HDR Cookbook – The Secrets of Hand-held HDR Shooting
Most HDR tutorials and books implicitly assume that you are using a tripod for your work. A tripod gives you stability, ensures that images are perfectly aligned straight out of the camera, and allows for long shutter speeds without blur. However, there are also a number of disadvantages, and in many situations you are forced to shoot hand-held. […]

HDR Cookbook – Why you need an artistic workflow
Have you ever uploaded an image to your favorite photo sharing site just to come back the next day and discover that there are certain features in it that you don't like? Maybe the sky is too dark, the colors have too much saturation, or the contrast is too low. The reason for this is not necessarily your technical workflow - it may be your artistic workflow that needs improvement. […]
My Images
Hey there, what I don’t understand is, if you shot this on tripod why would you not just shoot the REAL +4 and -4 images? I get that your camera doesn’t do 5 exposures in AEB but you have manual, why not just do those exposures manually? You’d get a better result from real exposures than faked ones. I do the faked thing for hand held, but tripod, there’s no reason not to shoot 5 for real. Can you explain the logic here?
You’re right, Darlene! In principle there is no reason.
In this very case, however, I was in a bit of a hurry. Imagine me running up and down the river, trying to get as many good shots during the blue hour as possible? I just did not have the time to do everything manually. On this shot, I used autobracketing instead. Sometimes, you have to make a choice.
I hope that explains it.
Yeah that explains it and I totally get chasing the blue hour. I might choose my spots with more scrutiny though so as not to be running around so much and just shoot less angles. But that’s just me.
Usually, I choose my spots ahead of time too. But, on this occasion I rushed from the airport to the hotel and then to the river just to catch the blue hour. The first spot I chose seemed promissing but turned out not to produce very good shots. Then I made a decision to run to this bridge and got there almost too late. So this was actually plan B.
A plan is a great thing… as long as it works.
I hope you’re having a great start to the week, Darlene!
How’s my week? Well let’s see, I spent 5 hours on Saturday in two Mac stores having my laptop issue diagnosed as hard drive failure, and getting a new one put in. Other than the stress of all that, I’m back up and running so I guess all is well.
correct the shutter speed equivalents
Corrected! Thanks!
