Sometimes a wide-angle lens isn’t quite wide enough. I took this shot at the wide end of my 17-40mm lens and it just couldn’t capture it all. The entrance to this hotel is amazing and is visible from across Boston Harbor (see here).
I used 5 exposures to make this HDR but I honestly could have gotten by with only two or three. As always I wasn’t trying to eliminate the shadows by using HDR but rather attempting to bring out some depth and tone down some highlights. Notice that the building on the left out by the harbor just disappears into shadow — that’s how it should be as it really looks that way. I used Nik HDR Efex Pro to create the starting image, then used a dark exposure to tone down a few of the bright lights. There was a bit of masking for the couple standing near the left, a couple of tonemapping artifacts fixed up, and basic contrast adjustments. One thing that bothers me a little is how the lights near the left doorway have quite a green tone while the lights on the right are rather white (I’m a poet and didn’t even know it). I decided not to balance them out — for whatever reason that’s just the way they were (see original exposure below).
Today I’m posting an HDR panorama of the Hanalei Valley in Kauai, Hawaii. The main crop in the valley is taro. I mentioned in another post that I rarely lugged the tripod around while out with the family but I did usually have it in the car. When we stopped at this lookout I went ahead and used to capture images for a pano of this valley. As you can clearly see the dynamic range was quite large, especially with the bright clouds. I quickly picked an exposure (using manual mode) and fired off 3 exposures per position. I didn’t want to hold the family up so I didn’t take the time to capture the whole dynamic range. As such, the clouds still are blown out in spots but it’s still a picture worth having from the trip.
I tonemapped each set of brackets using the same settings then used Photoshop to stitch them together. After that I simply tweaked the contrast. One obvious improvement would be to clone or crop out the branch sticking into the top left part of the frame but I haven’t yet taken the time…
I recently downloaded a trial version of Nik Software’s HDR Efex Pro. I’d been semi-disappointed in many HDRs I’d created in Photomatix and had heard many people say they’d made the switch to Nik. If you’re hoping for a complete review of Nik HDR Efex Pro I apologize in advance — I’m only going to give some impressions here.
First, a bit on Photomatix. It’s great software in many ways and I’ve used it to make many cool (IMO) images. However, in many of my HDRs of late I’ve ended up doing so much masking in Photoshop after tone mapping in Photomatix that I’m practically producing a composite of the original exposures. Photomatix often doesn’t handle motion to my liking — leaving way too much work to do afterwards. I’ll readily admit that it could be the user — I’m no wizard with Photomatix. It could also be that I’m getting pickier as time goes on. On the plus side, I find Photomatix to be much faster than Nik but I don’t process all that many HDRs so that’s not a huge factor.
I used Nik HDR Efex Pro to process all but one of the images in this post. For my own comparison purposes I processed another Hawaii coast photo — similar to the one at the top of this post — with Photomatix. It’s not completely apples-to-apples since I didn’t process the *same* photo but I ended up having to spend a ton of time in Photoshop fixing up the Photomatix image (basically ending up with a composite as I mentioned above).
As for the mechanics of using Nik HDR Efex Pro, it’s quite simple. In each of the images (5-ish?) that I’ve processed with it I’ve started out with a preset and tweaked from there. Of course I’m still learning all the sliders, etc. but I’m happy with it so far. I find the “control point” concept useful (it defines circles in which you can separately tweak portions of the image) but I would prefer that it worked more like the adjustment brush in Lightroom where you can choose exactly where the effects are applied. The final images here aren’t completely to my liking (some spots would get fixed if I were to spend more time on the images) but are illustrative enough for this post.
Most people who like to do HDRs are suckers for reflections. I’m no exception and when my children and I walked into San Antonio’s Alamodome for the NCAA volleyball championship I saw these shiny floors and decided to fire off some brackets. I set up the camera to fire 3 brackets (the max on Canon) with the auto timer and set the camera on the floor. It would’ve been nearly impossible to change the settings without moving the camera so I didn’t even try. I took another set of brackets with more crowds in the picture but the motion was too great to process reasonably.
I ran this through Photomatix and then brought the tonemapped image into Photoshop along with the brightest exposure. I used a few adjustment layers on the bright exposure to semi-match it to what I wanted to fix — the people in the hallway and a few other areas where ghosting had caused some weirdness in the tonemapped image. After blending those areas in, I went to work on the result with a half-dozen other adjustment layers (mostly curves). There are some missing people-parts but I don’t really mind as it gives a sense of motion and the work to clone in new pieces wouldn’t be worth it.
To do this image justice it really needs to be viewed large. Click here for the full-res version.
On a photowalk last weekend (see previous post) I shot some frames in hopes of stitching a panorama of the Austin Skyline as viewed from the SRV statue on Auditorium Shores. I bracketed my shots with a mind toward using HDR and/or compositing to capture most of the dynamic range. I had no intention of filling in the deep shadows of course — It was getting dark after all.
In processing I set off to try the HDR route (I believe this is my first ever pano in HDR) and based on advice from Dave Wilson I first tonemapped the separate frames (3 exposures used for each) using the same settings in Photomatix. I used something on the order of 60% “strength” and tried to keep the HDR look toned down (FYI, the original exposures really do have this much blue in them). I tweaked the perspective of the individual frames a bit in Lightroom then merged to a panorama in CS5 using the ‘cylinder’ setting for the stitch. I could write an entire post about my perspective and stitching issues but suffice it to say that using the ‘auto’ setting was giving me very skewed perspectives from my wide-ish angle frames (30mm on a full-frame body). The automatic blending of the exposures after the stitch usually does a bang-up job of matching colors and creating a seamless stitch but I did have to manually tweak one area to make it match. Hopefully it’s not too noticeable…I won’t point it out of course. The HDR was a bit too saturated for my taste (it still kind of is…can’t make up my mind how I want this to look) so I used the vibrance adjustment to tone it down. Curves adjustments were used in various places for some final tweaks. No original exposures were masked into the final image.
My wife and I just enjoyed a four-day weekend in Montana’s Stillwater County with four other couples (I’ll post a picture of this fantastically good-looking group soon). While out wandering among the ranches early one morning I spotted this rusty old tractor just off the highway. Dramatic skies + rusty tractor + twisted barbed wire + broken fence posts = great HDR scene.
I shot seven exposures to capture the entire dynamic range. Since I generally like to leave some deep shadows in my HDRs I probably could have done without the brightest exposure. Likewise with the darkest exposure…not *sure* that I needed it but I shot it anyway.
After tonemapping in Photomatix I fired up Photoshop with the intent of doing the usual blending with the original exposures and adjusting with curves. The image had a bit too much color saturation for my taste and as I tried different methods to tone that down I got the idea to turn this into an antique-ish photo. So, I used a channel mixer adjustment layer and tweaked to take almost all the color out, my new goal being to make it look like a photo that had been sitting under the glass on someone’s desk for fifty years. Five curves layers/masks were used and noise was reduced in the sky. All it needs IMO is a leather-skinned farmer leaning on the wheel with a blade of grass stuck in his mouth.
Photographers wish they could take all their pictures during the golden light of sunrise and sunset but for those of us far south of the polar circle (in the northern hemisphere of course) those are very brief moments in time. During my recent trip I wanted to make the most of my available time so I photographed what interested me regardless of the quality of light. Even the “poor” pictures make for good memories. Adding to the problem of harsh sunlight was a very thick haze. I don’t know if was related to the heat or possibly due to smoke from wildfires, but it was a problem for pictures.
One afternoon we stopped at the Sotol Vista Overlook to take some pictures. This desert overlook is roughly halfway between the Chisos Mountains and the Rio Grande along Ross Maxwell Scenic Drive. The small gap in the horizon is Santa Elena Canyon — 14 miles as the crow flies according to a sign posted here. Looks tiny but the canyon walls rise up to 1500′ above the river per the park service’s website. I bracketed a bunch of scenes and hoped for the best. I came up with this 6-exposure HDR (the first HDR I’ve done in quite a while) and I rather like it, especially considering the harsh light and haze. I made attempts at processing single frames but the dynamic range was way too large (I don’t own an ND graduated filter — yet – else I would have made use of it here).
Processing consisted of tonemapping in Photomatix, an s-curve, sharpening, noise reduction, and a slight color tweak with the channel mixer in Photoshop. I didn’t do any blending with the original exposures.
You know HDR is a verb, right? I didn’t realize until WordPress renamed my link that I’d used that title before (see that post here). Which do you like most? The non-HDR version (above) or the HDR version (below)? There’s no right answer of course but my favorite is the non-HDR image. I’d post them side-by-side but WordPress is giving me formatting fits…will update the post if I ever figure it out.
While in the Seattle area for a wedding last month my son and I went on a short photowalk in the little town of Snohomish. Snohomish is one of those cutesy towns with shops for tourists and all that. That morning it was just wet, dreary, and cold — somewhere in the high 30s with a stiff breeze to go along with it. The wet and dreary thing makes for decent HDR conditions typically but the cold I could have done without, especially having had temps in the low 80s when we left Austin the afternoon before.
On our walk I grabbed some brackets of these stairs for a semi-abstract image. It’s sort of urbex but maybe I’d call it “garden urbex” with all the moss growing (the stairs were surrounded by plants and flowers too). The dynamic range frankly wasn’t very high but as I’ve posted before one can get cool images just going through the tonemapping process. Last night I decided to process this scene but as I inspected the brackets I determined that using a single exposure would give me the image I wanted. Part of that decision was driven by the fact that I’ve gone through a few of David Nightingale’s (chromasia) tutorials and was itching to try my hand at some things. On a whim I took 5 exposures and did an HDR for comparison. It’s not an entirely fair comparison though as I only spent a quick 5 minutes tweaking the Photomatix output. However, I wasn’t really interested in trying to match the single exposure I processed. Rather, I purposely processed it without even looking at the single image so that I would rethink everything as I went through the process again (albeit very quickly).
Some details on the processing of the single-exposure image (shown at the top of the post): I began with the intent of going black and white but as I played with the channel mixer I ran across some color settings I liked. I ended up using -26 red, +129 green, and -7 blue. I used various curves layers to tweak parts of the image to taste (see the screenshot showing the masks below). All curves were simply adjusted on the RGB channel. This image was ripe for some individual color adjustments but I only have so much time for all this photo stuff.
A quick rundown on the curves layers: the darken and s-curve layers were blended in normal mode and the s-curve went a little stronger on the highlights side. The lighten and “curves 1″ (forgot to rename it) were in luminosity mode and as you see from the masks, targeted very specific parts of the image. Curves 1 was a very strong s-curve to bring out the contrast in the beam along the steps. “Lighten” brought out a bit of detail in the wet shadows in the nooks and crannies. I topped things off with a vibrance adjustment of +14 (the HDR image had a +25 adjustment b/c the curves layers I used didn’t bring nearly as much color as in the other image).
Notice that the original (below) has a piece of peeled paint on the bottom step. I cloned that out since it interrupted the edge of the frame. It fit with the image but was just in the wrong place. That’s the only cloning I did.
Cropping was difficult. Not quite happy with it but I was less happy with the 17 other ways I tried.
Posting a couple HDRs from the recent HDR Mafia photo shoot at Seaholm Power Plant. This door was at the top of a stairwell where I had hoped to gain access to the crane in the main turbine room. The crane door was locked as was this door which would have provided roof access. Fortunately we had access to the roof via other means but we never did get access to the crane.
Both images were tonemapped in Photomatix (6-7 exposures…don’t remember) then processed mostly via curves in Photoshop. I probably could have used only two exposures and gotten all the image information but I didn’t bother playing with that. The black and white version was simply a matter of adding a B+W adjustment layer to the image and tweaking the red and yellow adjustment. The color image used a series of masked curves, some of which were only applied to the red and/or blue channels. The lighting was actually relatively flat in the original exposures and I used curves to bring out the shadows more. The starburst in the keyhole was obtained by using an aperture of f/22.
I’m not sure whether I like the color or B+W version better.
Thought I’d post another image from the photog excursion to the Holly Street Power Plant. We had a great time and processing the images helps to re-live the experience somewhat. I also want to get through some of these images and pass them on to the folks at Austin Energy in a timely manner. Today we — a group of Austin photogs who somehow ended up being called the HDR Mafia — had a group lunch at Chuy’s. Every month or two we get together and talk photo stuff. It’s great to hear about what others are experimenting with, what they’re doing business-wise, etc. Not everyone uses HDR extensively but we all dabble in it at least.
The image at the top is a 6-exposure HDR which was taken in the generator room. Processing consisted of tonemapping in Photomatix, masking in pieces of various original exposures, masking parts of two layers processed with different settings in Topaz Adjust, then playing with a couple of curves layers and masking them in appropriately. I didn’t notice the blue glow until I got the exposures home…not sure where that came from. It adds a bit of mystery.
The image below is a 4-exposure HDR of a random beam with huge cables attached. This was also in the generator room. Countless items like this were available to shoot. I processed this image in a more straightforward-ish manner. I tonemapped in Photomatix, added curves adjustment layers to portions of the frame, and blended in a layer processed in Topaz Adjust (but I used a much more subtle preset than I did with the top image). I’m really not stuck on one way to process or one final outcome with these HDR images. It’s not like a wedding shoot where one needs to pay great attention to color matching sets of images and such. I consider each of these HDRs to be its own thing and play each by ear as I process. The outcome is greatly influenced by what I’m in the mood for at the moment.
Had a great Father’s Day this year! We spent Saturday night at our friend’s house in Fredericksburg and I woke up to a fresh cup of coffee and the sunrise in the image below (9-exposure HDR). It was such a cool morning (by Texas summer standards) so I just wandered around a bit and watched the cows graze.
We have so much fun with our friends and Sunday morning was no different as we enjoyed breakfast together and got ready for church. After church we headed home to meet our oldest (married) daughter and have a meal — of my choosing of course — together. The family got me something around 700 shirts which my son said was their way of telling me that they didn’t like my current wardrobe.
Speaking of being a father, we celebrated the birthday of one of our younger sons this past week. Whenever we celebrate our children’s birthdays I’m reminded of how old *I’m* getting.
Our son has become fascinated with cowboys of late (he wanted to invite Roy Rogers to his birthday) so we got him a cowboy hat and used matches for candles on the cake (seemed more like what cowboys would do). He loved it — “Mom, this is the BEST cowboy cake EVER!”. Here’s a shot of him getting ready to blow out his “candles”.
I don’t normally process single exposures (especially of people) as HDRs but I was inspired by Jayme Rutherford’s single-exposure turtle shot which you can view here. I decided that the cowboy theme lent itself well to the gritty texture that tonemapping an image brings about.
Since our trip to Paris it seems that I’ve never been able to catch up with “things”. Photography has certainly been a temporary casualty but I’ve managed to process most of the photos from the trip. Most pics got the quick exposure/contrast treatment but I managed a few HDRs as well.
We spent our six nights in Paris but included a day trip to London during the week. I booked us in “leisure select” (effectively what we’d call business class) on the earliest Eurostar between Gare du Nord (Paris) and London St. Pancras and then the latest train back to Paris. Frankly the train rides were quite enjoyable and relaxing. The image above was taken in the St. Pancras train station and shows a statue called The Meeting Place by Paul Day. The architecture (interior and exterior) of the train station alone would have made for a decent day’s photowalk. I read somewhere (probably wikipedia) that the station underwent a $1 billion+ renovation in the last decade. There are still some construction fences around portions of the exterior — I only noticed because they ruined some photo opportunities.
The pic below was taken on the bridge at the entrance to the Tower of London. A catapult sits in the long-ago drained moat surrounding the walls. While this image doesn’t really capture the essence of the Tower itself, it certainly helps me re-live that single day we spent in London. Sunny and warm, blue sky with awesome clouds — such a rarity in London. It seemed that everyone we met made some comment to the effect of “You sure got some of our best weather for your visit”.
The Tower was amazing. The history of the place is SO interesting. The Beefeaters tour was quite entertaining as well. We spent about three hours inside and that was skimming a lot of the text on plaques and such. We’d certainly go back and spend more time if we visit London again.
The HDR above was created using three handheld exposures. Tonemapped in Photomatix with some typical contrast, sharpening, etc…no blending with original exposures.
