Practical HDRI: High Dynamic Range Imaging for Photographers by Jack Howard is the latest book I have read on the subject. I haven’t touched my Photomatix software (indeed, even my camera) for some time. Reading through this book helped inspire me to get back out shooting photos, and also to see if Olympus was doing anything to help with the capture of HDR images. As it turns out, the recently released Olympus E-620 has far better support for proper image bracketing to get the exposures you need.

The book itself is fairly short - just 168 pages. But these pages are full of good information and practical examples using more than just one software package. What I like most about it is the frankness of the author when it comes to producing realistic HDR images, as opposed to some of the cartoonish extremes that have come to symbolize the genre. I much prefer a realistic image that has great depth in all ranges between the darkest and lightest sections of the image. In addition to the software examples (Photoshop CS3, Photomatix and FDRTools), the author tells you what to watch for when capturing the images, well before they see the computer.

All in all this was a very worthwhile book, with more than enough interesting bits for the novice and experienced alike. I would definitely recommend this book to anyone who is looking for more information on HDRI.

As previously mentioned, I took some time while in Durango recently and worked on my HDR images, specifically where real estate is concerned. I even followed the directions from the Photomatix people. While I actually took several HDR images on my trip, I was particularly pleased with the real estate ones.

The best one, the exterior shot above, is a combination of 4 exposures. I imported all of my images form the weekend into Lightroom, then selected them and corrected the white balance. I had shot them without resetting my settings from earlier experiments - thank god for RAW and Lightroom. I then took the 4 images and exported them using the HDRSoft Photomatix Lightroom export plugin. I then combined the images in Photomatix, adjusted the tone map until I had an image I liked, then saved it and went back to Lightroom.

I had some really bad converging verticals though, so from Lightroom I chose to edit the image in Photoshop CS3. Once in PSCS3 (say that 5 times fast), I used the Distort feature to straighten the verticals and make everything look proper. All in all, I am quite pleased with the outcome. I know there are free tools out there to generate HDR images, but none of the ones I tried came anywhere close to Photomatix in terms of resultant quality or ease of use. If you are seriously considering HDR photography, you really should invest in Photomatix.

Last week in Beaver Creek I was able to take advantage of the great surroundings to do some practice photos for real estate purposes. At the same conference, I met with the manager of a new property in the mountains that is wanting some photography done. They don’t have a budget per se, but do love to trade. So I am planning on trading my photography for a couple of nights in the property during ski season. Should work out well for both of us.

The picture above, while not quite what I wanted, was generated on my laptop from 5 exposures (-2, -1, 0, +1, +2) combined in Photomatix. It is my intent to do a full on review of Photomatix in the next couple of weeks. But all in all, I am happy with the result here. I’d like to lighten it a bit of course, but it does give the feeling of the view you get from my room at the Park Hyatt. I think that the next time I do this, I might be inclined to take 9 exposures, shooting at -2, -1.5, -1, -0.5, 0, +0.5, +1, +1.5, +2 and seeing if that results in a better image. I need to go back to my notes from the HDRI book I read so long ago.

I could probably hang my shingle out for this now, but I want to get it right before I start expecting people to pay for my time.

When you are shooting a room with a great view, it is a good idea to show that view, if you can. But that is more complicated when you think about the exposure levels outside versus inside the room. Since I was in an awesome location recently (the Park Hyatt in Beaver Creek, Colorado), I decided to use the property to do some practice on. I have posted a few images from this test in the Photography For Real Estate Flickr group (yes, it is a Flickr complement to Larry Lohrman’s excellent site/ blog) and have received some useful feedback from it.

HDR (high dynamic range) images are starting to take the photography world by storm (at the time of this writing, the HDR Flickr group has over 18,000 members). If you ask a room full of people what HDR is, you get a wide range of answers, and typically they are all partly correct. Simply put however, HDR imaging is the process of creating an image that encompasses a wide range of exposure values. This allows the resultant image to be nearly all encompassing in every detail. HDR Imaging has, until very recently, been the purvey of Hollywood graphic and special effects artists. “The HDRI Handbook” by Christian Bloch helps bring this exciting arena to everyone else.
