Working with Color Infrared

This is a technical post, which I never do, so apologies in advance.  I’m actually fairly enthusiastic about some recent developments that I wanted to share.  I have never enjoyed my only rather mundane efforts with color infrared images.  They never looked right to me, only somewhat “cooked” in digital photo parlance.  As such, I typically convert them to black and white and sometimes am pleased with the results.  I”ve been working with a new process for the past several months, and actually published a few results on my previous Earth Day blog.  I have continued to experiment and been relatively happy with the results so I thought it might be useful to share a few details.

The story begins with an e-mail from Kolarivision (my new Infrared camera conversion company with which I am quite pleased) regarding a course they were recommending.  Perhaps bored at the time, I thought I’d give it a try.   The name of the course is Creative Light and Infrared.  You can find out the details about the course here.    I’ll stress up front that I am not a paid endorser for this group, F64 Academy, have never met them, nor talked with them, ever.

The course offers an in-depth exploration of the digital infrared post production process, along with several  accompanying and quite useful tools.  If you’ve done any infrared photography, you know that there are a few significant challenges you face in post production, particularly with color.  The biggest one is that the white balance setting you use in the camera likely won’t hold once you bring an image into your average photo editing program.  It goes all red or at least mostly so.  Worse yet, most photo editing programs don’t have enough range in their white balance settings to be able to fix the problem.  Second, if you’re interested in color infrared images it can be most helpful to effect a “channel swap”, coverting the red channel to blue and the blue channel to red.  I’ve known that for years, but like many photographers was never, ever satisfied with the results.  Adding insult to injury, if you get an image to actually work for you, it is hard to replicate it.

The course walks you through the process of creating a Lightroom/Camera Raw profile that you can apply to your images and effect a nice looking white balance.  In addition, the course provides a set of LUTS that layer on top of the correctly balanced image that will offer you various different channel swapped looks, including looks that are fairly photorealistic. Finally, the course ships with an extensive panel of actions for use inside photoshop, as well as detailed instructions for their use.

So enough with the jargon.  These are from my work with mills in the Blackstone River Valley of Central Massachusetts.  The first two are of the Bernat Mill in Uxbridge, Massachusetts.  The mill burned in 2007.  The last is from the Wilkinsonville Mill in Sutton, Massachusetts.  Wilkinson was an associate of Samual Slater, the first builder of mills in the Blackstone Valley.Hunt_190509__DSC0572-Edit-2Hunt_190509__DSC0576-Edit_DSC0802-Edit-2

This is still a work in process as you can see, but my interest hasn’t flagged so far.  One of the most interesting aspects of photographic work is the almost never ending opportunities for learning that you can stumble across.  Courses like this aren’t cheap, and some are duds.  This one was helpful.  Of course, YMMV.

 

Earth Day Greetings

My work in the Blackstone Valley of central Massachusetts and Rhode Island constantly reminds me of the tension between human activity and the environment.  Tension of course can lead to both positive and negative results, on occasion simultaneously.  We visited the Blackstone Gorge yesterday, and tried to picnic at the Roaring (or Rolling, depends on who you ask) Dam.  It’s a beautiful spot.  There’s been a dam here since the early 1800’s.  The purpose of the dam was to create a power supply for the explosion of textile mills built along the banks of the Blackstone River.  The mills are long gone.  The water is getting cleaner thanks to the work of many citizens, communities and various government agencies.  But the sediment, the dirt under the River, is still toxic in many places.  Removing the sediment will be enormously expensive.  Perhaps too expensive.  But we’re left with the water’s beauty.  A good deal?  Perhaps a good lesson.

What Next?

I live in the Blackstone Valley of central Massachusetts which continues into Rhode Island.  I’ve written here about the Valley in previous posts.  I love it here for many reasons, but one of which is that history is so visible, nearly everywhere.  That’s a feeling I appreciate.  I grew up near Williamsburg, Virginia.  You could drive to the historic region there and if you could find a place to park, you could walk right out onto Duke of Gloucester St., and back into time, at no charge (then, not sure now).  By that time, the 1960’s, Williamsburg had been fixed up, restored as it were to its former architecture.  In the early 1900’s you would have seen the same buildings, but not in nearly so pristine condition.

The historical artifacts of the Blackstone Valley lie somewhere along that continuum.  Those artifacts, specifically mills, or we what might be more generally termed factories, stand out from the otherwise rural or suburban landscape.  The mills were built along the Blackstone River or one of its tributaries.  They were located to take maximum advantage of the flow of the rivers and their ability to turn water wheels.   Those water wheels connected to the machines that for the most part spun and weaved cotton and wool fabrics.  The connections involved elaborate sets of gears and belts.  The mills were usually built up, not out, in order to create a more compact operation and take advantage of the strengths of such power systems.  The industrial revolution in the United States began here, in the late 1700’s.  The textile industry boomed, creating considerable wealth.  In the twentieth century though, the industry largely succumbed to competition first from the southern U.S. and then from off shore.  The businesses located in the mills ultimately failed or moved, for the most part.  The mills and the ancestors of those that worked in them (and didn’t relocate) remained.

It can be pleasantly jarring to drive along a relatively rural street, or walk through an old New England style center of town, and suddenly come upon a mill or what is left of one.  They were frequently quite large.  Not as large as those built along the Merrimack River in northeastern Massachusetts, but impressive nevertheless.  Some have burned (one hundred years of toxins can set the stage for quite a fire).  Some sit idle and some have been repurposed to mix use or most successfully it appears, as housing.

The mills tell a story that highlights the power of economic development.  These are just buildings though.  Obviously there’s more to the story.

Holding Back the Water: Updated Video Link

I’m so sorry, but for those of you, nearly all of you, who follow this site on a mobile device, the video link in the blog posted earlier today was broken.  WordPress just doesn’t play nice with mobile devices and video.  The proper link for the November 2018 Woonsocket Falls Dam (which was pretty interesting) is posted here.

Thank you.  No more emails, promise.

 

Holding Back the Waters

With every tick of the clock it seems our ignoring of climate change becomes more menacing.  Climate change isn’t coming of course, it’s here.  At this rate, it appears that we may well not act in time to prevent the rising sea levels and other impacts of climate change from significantly altering our shores and our lives.   At the risk of sounding quite pessimistic, what’s known as “mitigation,” lessening the impact of climate change rather than preventing it, will almost certainly have to play a role.   Who will likely play a critical role in that event, at least in the U.S.?  You may or may not like the answer:  the U.S. Army Corps of Engineers is a leading contender.  We heard a lot about them during the lead up to and recovery from Hurricane Katrina in New Orleans.

Their presence in the South and along the Mississippi is well known, but what about New England.? Much like climate change, the Corps of Engineers isn’t coming, they are already here, big time.  Their role is largely focused on helping to prevent serious flooding.  Their surprisingly heavy, in my view, involvement in just the Blackstone Valley may offer some insight into what their activities will look like.  Keep in mind that that these examples are just a few out of many many activities in which the Corps is engaged.

The Blackstone River travels from Worcester, Massachusetts to Providence, Rhode Island.  Along the way, it falls about 500 feet.  That fall involves the release of a considerable kinetic energy.  It can easily turn a mill’s water wheels and provide sufficient power for major industrial activity.  The Blackstone was the site of America’s first textile mill, in Pawtucket, Rhode Island.  The River also floods, routinely.  Some of those floods have been extremely damaging, resulting in the loss of life and tremendous loss of property.  That’s been the focus of much of the Corps work.

The impact, present and future, of their work was brought home to me when we visited Woonsocket Falls dam, in November of 2018.  To begin the story, here’s what we saw on a previous visit, in July 2017.  hunt_170716__1000279-edit

Suitable for fishing though I’m not sure I’d recommend it.  Actually the image below is from August 2016, same location.  Our friendly heron was taking her time, the water was very low, just the right height for a relaxed afternoon fishing expedition.

Fast forward to November, it looked like this (the video is 45 seconds):

If you’re looking in on a mobile device and don’t see the video click here.

A bit more impressive, you’d have to agree.  The River is capable of significant variations in its height and flow.  This was after a wet fall, but it can, and may become, a whole lot wetter.  This dam was built after a serious, life threatening flood in 1955.  The volatility of the River has drawn the interest of the Corps of Engineers all along it’s route.  The gates you see can be raised or lowered to control the flow of the River.  The dam cleverly also supplies hydroelectric power.

Just a bit north of the dam, you can see how the River was “channeled” by the Corps.  The channeling also helps maintain human control of the River.  However, channeling also inhibits the natural exchange processes between the River and the shore, processes which can help restore a river, among other things.

hunt_170924__1000357

The channeling runs through the City of Woonsocket, as well as in quite a few other populated  and industrial areas.

hunt_170924__1000459

At the other end of the River, in Millbury, Massachusetts, you’ll see the large Diversion Channel.  The Channel connects with the River and which normally looks like this (below).  It was dug in the late 1940’s again in response to flooding in the City of Worcester and surrounding towns.  Normally its nearly empty.

hunt_151017__dsc9594-edit

After our wet fall in 2018, it looked like this (below).  The Channel acts like a temporary reservoir, a place for excess water to go rather than flowing into city streets.

_dsc4101-edit

Diversion strategies like this take a lot of land.  There’s a larger diversion area along one of the tributaries of the River, the West River, in Uxbridge, Massachusetts.

_dsc3000-edit

If the River moves toward flood stage, flood gates in the dam below are closed storing water, allowing the water level to fall gently over time.

_dsc2996-edit

The dam itself is 2500 feet long.  Behind the dam is a large stretch of protected land, over 500 acres that is largely managed as a park (by the National Park Service).

It is striking how many resources are already going into holding back the water.  Again, this is only a small fraction of what is taking place, largely unnoticed.  That is not to criticize the work done by the Corps.  Much of it, at least in New England, is done to protect life and limb. If you’d like a more comprehensive run down, click here.

But, this is a big deal, one that is very expensive.   The projected budget for 2019 is on the order of 4.75 billion dollars.  Intervening in nature can also be very problematic, as the citizens of New Orleans and environs know.  The management of the Mississippi River is perhaps even more problematic.  We may be headed for the need to greatly expand their work, by a very large margin.  Prevention or mitigation?

I’ll close with a couple of images from a “wall,” also constructed by the Corps, that actually does some good.  These are the massive hurricane wall and gates that protect the City of Providence from flooding.
