HDR Timelapse – Las Vegas

Today I edited the HDR Timelapse sequence of the Las Vegas sunset.  I had shown one frame from the sequence over the weekend and posted a larger version previously as well.  This is one single tonemapped edit from the HDR Timelapse sequence. (Video link to Vimeo below).

Today I had a real estate shoot cancel, so I got a bunch of past real estate shots edited and then took some time to piece together the Las Vegas Sunset HDR Timelapse.  Because I chose to merge to hdr and tonemap that one single image over the weekend (above) using Photomatix Pro, I thought I’d use Photomatix Pro again for the entire sequence.  What the hell.  Its not for a client so a little over saturation won’t matter here.  I made a few mental mistakes in the pipeline because I generally use other apps, but the results are O.K. for government work  :)

This was the capture/post flow:

Nikon D3  + Nikon 85mm f/1.4D shot through my hotel window on a tripod utilizing the in camera HDR Timelapse (You can combine a timelapse with bracketing in the D3).  I chose to go with a 7AEB with 1EV steps and the camera was firing off that bracket every 15 seconds.  Of the 7AEB I killed off the final over exposed image of each bracket.  I felt adding that latitude would brighten the image too much.  So each merge to HDR was 6 shots spaced 1EV apart.  The total number of tonemapped shots was 90.  Basically covering a span of  22 mins 30 seconds worth of time during the sunset. Both the Merge to HDR and Tonemapping was done in the batch feature of Photomatix Pro.  I then took the tonemapped images into Final Cut Pro for time and color treatment before exporting for YouTube & Vimeo.

Because I shot this sequence in portrait mode, I opted to make slight color correction differences to two versions and post one video with both playing together.  I should have pushed on image a lot harder to show variation.  Now that I’ve watched it online it seems very subtle.

I also simultaneously shot a HDR Timelapse a foot away from the D3 with a Canon T2i in horizontal mode as wide as the kit lens will go (18mm for that EF-S, but on a crop body).  I shot for a full hour with the T2i.  About 15 minutes prior to setting up the D3 and the same after the D3 exhausted the compact flash I had in it.  It will be interesting to see those results versus the D3.

I’m no expert when it comes to compression/encoding.  I can only say that the video looks a hell of a lot better in FCP than online!

Vegas HDR Timelapse

I have a lot to share regarding NAB and HDR, from cameras to software. For now just a quick peak of one frame of a sunset HDR Timelapse sequence. I haven’t processed the sequence yet, I just grabbed one frame to quickly process (Nikon D3 + Nikon 85mm f/1.4D set to AEB).  I decided to do what I never do…  use Photomatix Pro to get a saturated and more surrealistic looking tonemapped image for feel.  Because that’s how I feel about Vegas.  Warm and glowing.

I got a ton of shots, but didn’t shoot as often as I had thought because of a few time consuming reasons. I had food poisoning one night/day as well as both speaking briefly in the Post Pit at NAB and also spending two days trying to see all there was to see at the NAB Show itself (which is so big, that words fail to describe).

More to come next week, but I have back to back to back shoots lined up with builders this week for properties that have to be shot right away.  Its torture not being able to process the Vegas stuff right away, but all in good time.

Another quick HDR capture I chose to tonemap via Photomatix Pro
(Those two images will likely be the last I run through Photomatix Pro for some time. I’m just not thrilled with the way it handles color and has more than subtle hue shifts that cause saturation/hue issues)

Dynamic Range of Sensors

Dynamic range of sensors varies from camera to camera. You might be surprised by the (updated) chart below because the dynamic range of sensors is not as directly related to camera costs as you might think. You’ll notice that some mid level DSLRs are way ahead of the curve over other camera’s pro level cameras when it comes to dynamic range of the sensor.  This test was conducted by DXOmark.com and you can go there to read about how the tests were conducted.

|||—— UPDATED FOR NEW CAMERAS TESTED BY DXOmark.com —–|||

What is important and relevant to HDRI is the dynamic range of your sensor. It really matters.  Unless you taking large and tight brackets of each scene then it really, really, REALLY matters even moreso than you think.  If you are following a technique taught by someone using say a D3x and they tell you all you need is X shots, but you are using a camera at the bottom of the chart below and taking the same number… there is no way you can match that person’s results. Its mathematically impossible.

I get asked all the time how many shots do I take when I shoot, but nobody asks me with what camera.  Everyone assumes they are all about the same for HDR.  They aren’t.

Gear used for capturing brackets for HDR is even more critical if you are only taking 3 shots.  It will directly impact the quality of your HDR file. IF YOU ARE SHOOTING FOR VFX WORK THIS IS SLIGHTLY LESS CRITICAL THAN IF YOU WILL BE TONEMAPPING FOR REALISM (only slightly less though).

I’ve captured and tonemapped over 13,000 images for architecture, real estate and commercial shoots.  I’ve forfeited all my vacation time the last 4 years just to do intensive testing about what works better.  Gear, post production, you name it.

I’m pretty obsessive compulsive about trying to get a realistic looking image for real estate interiors and I’ve bought and/or rented about 40% of the cameras on this list below. DXOmark.com seems on the mark as far as my personal results are concerned.

Dynamic Range of Camera Sensors (I chose to focus on modern day digital models only)

No test is perfect. DXOmark has attempted to do this objectively, but because ISO/Noise and how cameras can handle scenes, colors and other differing factors, this should not be the only way to base your purchasing decision.  For example…

Someone could use the Canon 1000D (also known as the Canon XS) plus a piece of gear to get pro HDR captures.

If you bought that entry level Canon 1000D/XS for $400+ and a PROMOTE CONTROL for $299, (which will soon be adding HDR Timelapse to its functions in addition to HDR capture and standard Timelapse), then you could take very large and tight brackets with the Promote Control attached to your 1000D/XS that will capture well beyond what the in camera AEB capabilities of every single camera on that chart above.  Yes, including a D3x or 1Ds Mark III.  Sometimes the piece of “kit” you add to the mix can make a lower end device perform very well (dynamic range speaking here).  Of course the pixel quality of a D3x/1DsMarkIII is easily better than a Canon XS, but at the cost of $8000 it should be.

D700s Release Date

D700s release data? I get that question every week.  Guys/gals, I have no inside information, but what I know is the following:

The Nikon D3 was announced August of 2007

The Nikon D700 was announced July of 2008

The Nikon D3s was announced October 2009

The Nikon D700s …

Nobody knows.   But when I saw people on forums and on blogs saying the D700s should release soon back in summer of 2009, I knew they were wrong simply because there was no way Nikon was going to miss out on D3s sales.  So I said in a blog post last summer that the D3s would release first simply based on corporate philosophy. Nikon looks at everything in dollars and cents regardless if timing for us makes sense (and in a way timing for them doesn’t always make good business sense, but they ignore common sense just as Canon, etc. does at times).

Fast forward to pre-PMA.  It was quickly approaching and the same level of anticipation began online hoping for the Nikon D700s.  Based on past camera releases it was very unlikely they would have announced the D700s at PMA given the D3s had only been well stocked for a few weeks across the country.  Still no D700s release dates and I’m not at all surprised.

Given “Photokina 2010″ is later this year, they ‘may’ wait for that event to announce the D700s.  ”May”.  Personally I think that would be a mistake given the pent up demand for the D700s.  The amount of google searches that happen daily for D700s – Nikon D700s – D700s Release Date etc is astounding.  People want that full frame with insane low light capabilities, video and an autofocus system that is so far above and beyond the Canon 5D mark II that you can’t really compare the two cameras equally.  From a stills only comparison, the D700s wins over the 5D mark II in dynamic range, autofocus and low light abilities (the sensor will be the same as the D3s when the D700s releases, hence the ability to compare).  However, for video… to be fair, the 5D mark II’s video quality and resolution are currently beyond that of the D3s and likely the D700s when released.

If you are wondering why I’m even focusing on the D700s, well… I want one   :)    My D3 is awesome, but I’d love to have video in it.  I was going to get the D3s and sell the D3, but opted to just wait and add a D700s as a backup body instead.

Of course Nikon might just skip a generation and release some other camera with a new moniker ( D800 etc. ).   I have no inside info.  I’m only referencing the D700s because it makes logical sense to just follow the D3s as they did the D3 with the D700. Hopefully they don’t take the nearly 11 months they did with the D3 then D700 schedule.  If they do then Photokina 2010 is a logical place to do so.  Seems far to predictable for anyone to be surprised if they wait… so why wait? Capture pre-summer sales and get the thing announced in the next 60 days and shipping before summer begins.

HDR Shootout

I’ll be in Vegas for a week in April. I only needed to be there for NAB, but extended the time I’ll be there a little before and after to have time to play (errrr…. work).  My idea of playing is about as geeky as it gets.  I’ll be torturing my gear on some HDR Timelapse and some other shoots I’m considering setting up to test speedlites.

I’m doing this because I never have time to do this when I am grinding through shoots on a weekly basis.  I’ll have the time to do so when I’m away.  I’ve always been curious about comparing cameras shot in the same light with the same lens to see what differences you get. I’m not bringing all my gear, but enough to be considered certifiably insane.

I’ll be messing around with the following cameras during the shootout:

Canon T2i / 550D
Pentax K-x
Sigma SD9
Sigma SD14
Nikon D3

I already use the D3 and SD14 extensively on a weekly basis for HDR work (real estate), but will be torturing them in different ways on the trip.  I’ll shoot the D3 and SD14 for HDR Timelapse simultaneously side by side, both with wide angle lenses. I expect the results will be like shooting with two different film stocks, but I’ll find out for sure in post.

Also I will be swapping out (removing) the Sigma SD14 SA mount and installing a custom Nikon F-mount on the SD14 using a 3rd party solution. I have three SD14 bodies so I’m willing to risk bricking one for the team.  This will allow me to test the Canon T2i and Sigma SD14 using Nikkor Primes (in the case of the canon, via a F-mount to EF mount adaptor).

So I’ll be testing the Canon T2i vs the Sigma SD14 with the following Nikkor Primes (which have aperture rings):

20mm f/2.8D
24mm f/2.8 AI-S
28mm f/2.8 AI-S
50mm f/1.4 AI-S
85mm f/1.4D
105mm f/2.5  AI-S

I’ll be curious to see which camera resolves detail better… the latest 2010 release from Canon ( T2i / 550D ) or the 3 1/2 year old Sigma SD14 that tied the Canon 5D in multiple head to head image tests worldwide.  Also (and more important to me in many ways) I want to see which camera captures more dynamic range per shot (single shots).  And finally, I’ll fire off brackets with the same settings on each camera to then merge to HDR to see if there are differences there as well.  I’ll do this while testing various white balance settings, including custom white balance settings on each camera.

Just so that I don’t completely geek out the entire trip I’m also planning to setup some kind of high fashion shoot with Las Vegas models – MUAs and Hair Stylists.  I’ll test out some multiple speedlite setups on some models as guinea pigs as I have on models in the past (all my model shoots are actually new gear test shoots and I tell them this up front).

Past guinea pigs:

I might add something else to the mix, but so far these are tests I plan to do for sure.

Sigma 8-16mm f/4.5-5.6 DC HSM

Sigma 8-16mm f/4.5-5.6 DC HSM for APS-C sized sensors has just been announced by Sigma. Sure to be a favorite for landscape and architectural photographers.

Probably the most encouraging thing about the release is how several of the lens elements have been upgraded over coatings used for their other wide angle offerings.  Performance from this lens should be solid, but I’ll be reviewing it once I’ve gotten my hands on one and shot with it.

Also, generally the widest end of a zoom will be a tad soft in the corners so this lens “should” improve in quality as you zoom in a tad.  It might be possible that at 10mm it will be sharper than Sigma’s current APS-C wide angle zoom offering (which I own and use on a Sigma SD14).  I’ll be able to compare the Sigma 8-16mm f/4.5-5.6 DC HSM to the Sigma 10-20mm f/4-5.6 DC HSM head to head.

The Sigma 8-16mm f/4.5-5.6 DC HSM is equal to the following 35mm equivalent on the following cameras:

Nikon APS-C cameras = 12-24mm (35mm equivalent)
Pentax APS-C cameras = 12-24mm (35mm equivalent)
Sony APS-C cameras = 12-24mm (35mm equivalent)
Canon APS-C cameras = 12.8-25.6mm (35mm equivalent)
Sigma DSLRs = 13.6-27.2mm (35mm equivalent)

Sigma has also announced the following lenses:

Sigma 85mm f/1.4 EX DG HSM

Sigma 70-200mm f/2.8 EX DG OS HSM

Sigma 50-500mm f/4.5-6.3 DG OS HSM

Sigma 17-50mm f/2.8 EX DC OS HSM


NEW CAMERAS

Sigma SD15 ==> which now has 5 AEB at +/-3.0EV (that’s huge!!!)

Sigma DP1x

Sigma DP2s


And finally, last but not least, they have updated their RAW processing software program SIGMA Photo Pro to 4.0 which now is multi-core aware and is claiming it will improve IQ for all cameras.

Dynamic Range

Dynamic range of a camera’s sensor varies per model. Some manufacturers are better than others. The chart below shows scientific, but real world results of testing a camera sensor’s dynamic range. The tests were done by DXOmark.

Bigger is better when it comes to Dynamic Range of a sensor. It means you can capture more shadow detail and more highlights in a single shot. If you shoot architecture or landscapes you already appreciate the challenge of capturing a high contrast scene that has a massive dynamic range.

For HDR captures, this is incredibly relevant because an HDR file is only as good/clean as the RAW data you feed into the merge.

You can see below that Fuji was WAY ahead of it’s time with the S3 & S5 (fuji’s S3/S5 results apply when using the extended dynamic range feature which is controlled by a camera setting). It is no wonder that so many wedding shooters swore by that camera for shooting beach weddings and other high contrast scenes. As of now only the D3x can better the dynamic range of a S3 or S5 in one single shot.

The relevance to High Dynamic Range Imaging is the following. Lets say you capture a bracketed sequence with only 3 shots. Which of those cameras above do you think will give you the best data to work with when merged to HDR? Remember, an HDR file is only as good/clean as the RAW data you feed into the merge. If each RAW shot you feed into a merge to HDR has by itself a large dynamic range, then you increase the quality of the HDR file.

This is why I groan when I see someone shooting with a Nikon D3x or Fuji S5 Pro say you only need to take X shots to get X results.  Each camera is completely different in terms of its ability to capture dynamic range so when you limit your bracket to only 3 shots, the dynamic range of your sensor becomes incredibly relevant. As you fill in the gaps and take more shots with tighter EV steps it fills in data gaps and provides cleaner RAW data for the entire range.

I first touched on the subject of dynamic range of camera sensors about six months ago and there is a little more insight in that post which is linked HERE.  Other articles surrounding dynamic range, auto bracketing and FPS capture are linked as follows:

Autobracketing for HDR – Camera Specs

Fastest DSLRs for HDR Capture (wide AEB range only)

When I see someone say their HDR files and tonemapped images have noise issues, my first question is? How many shots did you take and what EV step between?  Because I can tell you I have ZERO, NONE, NADDA, ZILCH, GOOSE EGG issues with noise in my files.

Why?  Because I bracket big and tight.  Sometimes I’ll bracket a scene with 13 images at .7EV between steps or even more shots with only .3EV steps between.  And yes, it takes a lot longer to merge to HDR, but it also means the averaging that occurs in software from darks to lights between the RAW data you feed it will result in BOTH cleaner data (less noise) and milder hue/saturation shifts (better color reproduction).

I get asked weekly how my images look so free of noise, natural and how I control saturation levels.  That last paragraph is HALF the battle folks.  It took me about 2000 HDRs to finally figure that out and even though I recently crossed 13,000 commercially delivered images tonemapped from HDRs, I’m still learning and tweaking.  I’m far from satisfied with my own results.  It is a constant challenge for myself even to fight “overcooking” images to the point that a client comments “it looks fake”.

It is critical that you understand my goal is to get to the point that someone can’t tell I’ve employed a High Dynamic Range Imaging workflow / pipeline. I’m not there yet.  If your goal is to create colorful and possibly more saturated images than I am gearing for then you might not want to bracket tighter like I do because when luminance ranges get stretched in software using only 3 shots from an AEB sequence it by default will create hue shifts and saturation issues that you might actually want for your images (particularly if you are going for artistic and/or grunge looks).

Even if you don’t shoot for HDR I hope the chart at least enlightens you to the abilities of those camera models.  I’ve purposely eliminated the medium format cameras that DXOmark has on their site.  If you go to their site and want to check these stats out yourself then look for the following tab on their site (image below). When you do, that data will populate the field on the right so you can see the various cameras and how they stack up.  The X axis shows time so you can see when each was released in comparison to others.

Handheld HDR Wide Angle Shooting

Handheld HDR Wide Angle Shooting just got easier for Nikon shooters using full frame bodies.  Pre-PMA Nikon just announced the NIKKOR 16-35MM F/4G ED VR lens.


What this amounts to is for the ability to shoot with lower ISO levels when shooting hand held HDR Captures (AEB sequences/bursts). Finally a stabilized ultra wide angle lens useful for full frame shooters using the D3 D3s D700 (and D700s or D800 when/if released).

Nikon’s product page for the Nikkor 16-35mm f/4G ED VR is HERE

HDR Video

HDR Video is something I started toying around with in 2007.  The post production side of it was a challenge and a whole series of blog posts to touch on what I’ve found to be “best practices” for me.  The image below shows one single frame of the video. Each frame actually consists of 7 shots taken on continuous shutter release at 9fps on a D3.  Each frame was merged to HDR and tonemapped and then laid down in Final Cut Pro’s timeline.  The D3 was on a tripod with a fluid head and it was a manual (not perfect) tilt move.

I started doing the HDR Video segments for architectural shoots for builders, architects, realtors, rental companies, vrbo … the kitchen sink.  I had exported them out for video CD-Roms and marketing DVDs. The problem then was that the whole HD-DVD versus Blu-Ray DVD was a battle that had not been fully settled yet.  So I didn’t bother exporting out the segments to high definition.  I’m going back to old hard drives and bringing that footage back online into Final Cut Pro and doing that now so that I can export out to 720p for Vimeo and 1080p for YouTube.

The first one I converted to HD was not an architectural interior, but rather a segment I shot near the back yard of a client’s home for sale that happens to bump up against a state park here in North West Florida called “Eden Gardens”.  I’m still exporting and uploading the YouTube 1080p version and that won’t be done until later tonight after the Super Bowl, but the Vimeo 720p version is live now.  I’d let it cache and watch it full screen.  There is also a link to the right and below that allows you to download the video to your computer if you want to see it in much greater detail.  It is 720p, H.264 quicktime at 30fps.

I’m not even going to embed it. You really need to view this at full rez.  Here’s the link:
HDR VIDEO on VIMEO – 720p HD

I’ll be uploading more videos in the coming weeks.  All were shot from 2007 to 2009.
