Fire on the Flats • Salt Creek Flats, Death Valley National Park, CA

Hi everyone and welcome to today’s post. Today I am bringing you a little color and a little intensity. The image was shot on the Salt Creek Flats, a large expansive playa of heat tortured earth. Here in the summer the temperatures can reach well over 115 degrees. The heat leaches the salt and minerals from the soil which leaves the earth with a myriad of patterns, salt circles, ruptured soil, and the occasional pool of water. In the winter, when this shot was made, the temperature is more moderate and in fact very pleasant. Alec John, Travis Bechtel, and I spent several days exploring and shooting in the flats. It is a habit we have to shoot and scout locations multiple times in order to get to know the conditions and find interesting compositions. This was made on the evening of our second visit to this area. We had experienced amazing clouds through out the day and geared up for a potential “special event” for sunset. We were not disappointed. The clouds thinned along the western horizon and cleared the way for the sun to really light up the clouds moving in from the east. A large amorphous dragon-like cloud began to spread out over the playa and I began to look for a location to pick up a nice foreground and some water to capture the intense reflections of t he cloud. I found this beautiful round pool rimmed by puckered soil and a rime of salt. I began to shoot as the color started to happen. The intensity built till it looked as if the entire cloud was on fire. About fifteen minutes later it was all over as the flats entered the twilight zone of darkness.

How I Made the Shot: As a matter of photographic practice I often use a series of graduated split neutral density filters in my work. The filters allow me to balance the exposure in high contrast scenes such as this shot. Here the sky was well over 4 stops brighter than the foreground. So a split would allow me to expose for the foreground and hold back the sky creating a balance exposure. But on this trip I was experimenting without using filters. To capture the full range of light I made bracketed exposures-usually 5 stops but sometime 7, in the following increments: -2/-1/0/+1/+2 or -3/-2/-1/0/+1/+2/+3. In this way I was assured of having the data I needed to make blended exposures in Photoshop. I have found on recent shoots that I prefer this method as I not so intent on fumbling with the filters and instead looking at the light and watching it unfold. I can set the bracket sets on the camera and freely shoot. Back in the digital darkroom I can process the RAW files and bring them into Photoshop for blending. In this case I only needed two RAW files, one for the sky and one for the foreground, to make the final master.

Thanks for stopping by today.

A Thin Line of Light, Death Valley National Park, Ca

Hi everyone and welcome to today’s post. The other day I glanced at the image count in the Lightroom Database for all the shots I took on my recent Death Valley trip. Alec, Travis and I had 8 total shooting sessions. The amount of time we shot during each session varied based on the quality of the light. In general though we shoot early morning sunrise and late afternoon to evening sunset. During the day we scouted, ate, downloaded and backed up images, and other housekeeping details. So the final image count which included brackets of the same shot to ensure I had all the data needed to process the RAW files was 1795 shots. That works out to an average of 224.375 shots per shooting session. I am still scratching my head on this one. The numbers from the camera do not lie. But I for the life of me just do not remember shooting that much. But in a recent discussion with Alec we did conclude that the overall quality of light and shooting conditions we encountered was extraordinary. In addition Death Valley offers so many compositional possibilities. The end result we surmise was a perfect storm of shooting conditions.

Of course this does not mean that every shot I took was a winner. This is far from possible. But there were a lot. And Alec and Travis and I do agree that pound for pound we all got more keepers than we normally would get on an average shooting trip. The trip was also a bit of a departure for me in terms of how I shot. I began to look beyond just the shot and consider the processing possibilities. In the past, and this is based largely on my days with a 4 x 5 camera, I would seek to capture intact the shot I saw. I used whatever filters and other conventional means at the time to effect that capture. In Death Valley, save for occasional use of my trusty Warming Polarizer, I left all my filters in the bag. I did not employ a single Split Neutral Density. Instead of fumbling with the filters I was free to really shoot and explore potential compositions. And apparently shoot I did. The door opened and a thin line of light led me down a different path. I set my camera to record bracket sets in one-stop, and on occasion 2/3-stop, increments, composed and shot. The freedom allowed me time to watch the light and react to changing conditions. Quite honestly it was liberating.

Today’s image came from one of my bracket sets. I passed this over several times before returning to process the RAW files. Here I was drawn to the convergence of lines of water into a single flow that disappeared into the horizon. The water was beautifully illuminated by the rising sun, and for me, came to represent my new path. I do not know how long I will be here. Such is the nature of photography. But for now I will just follow the light.

Thanks for stopping by today.

Sunset at Lands End • Ellingson Island, North Shore of Lake Superior, MN

Hi everyone and welcome to today’s post. Today’s image is just an interlude. A brief and still moment in time where day and night begin to overlap. At the moment it is a metaphor that represents my current situation. Right now, at the mid-point of the holidays I seem to exist in the transitional spaces of time. I have taken down my website, for good or bad, and am in the throws of rebuilding the site under a new architecture with WordPress. I have been thinking about this for some time and finally pulled the plug. Had I been on my game I would have built the new site early and made a smooth transition to the new one. But alas I simply procrastinated, unsure of where I wanted to take the whole thing. But it is coming together and I think I will be ready to relaunch in about a month. And there is more photography to come as well. I have two early trips planned in January to Death Valley with my buds Alec Johnson and Travis Bechtel and another trip at the end of the month to the Grand Canyon that will include a trip to Canyon X and a day of shooting with Tony Kuyper. So good things are going on.

In the meantime please enjoy today’s peaceful moment from Lake Superior. The image was made at sunset on Ellingson Island at Split Rock Lighthouse State Park. I shot this during the North Shore of Lake Superior Workshop I assisted on with Alec Johnson. This was one of the last shoots of the workshop and was a beautiful and fitting end to a great time with a fabulous group of people.

This will be a the last post for about a week or so. I will return from Death Valley next week and I hope to bring you a lot of new images and adventures from the trip.

As always thanks for stopping by and supporting this blog.

Sunset on the Flats, Death Valley National Park, California.

Hi everyone and welcome to today’s post. My apologies for my apparent lack of attention to the blog but the last month has been quite busy. I have also been spending a good bit of time on my site over on Google Plus which has been very exciting. I have made quite a few new connections with the photography community resulting in new friendships and shooting opportunities. And speaking of shooting opportunities today’s post is a teaser. This image was shot nearly 10 years ago on my first trip to Death Valley. It also marked the first time that I shot with my 4 x 5 camera and Fuji Velvia film. Photography has really advanced since those early days with the large format camera. Today digital photography affords the opportunity to shoot more often, the freedom to experiment, and the ability to capture a broader dynamic range in my images. But my 4 x 5 work set the ground work for how I shoot today. Even with my digital cameras I use many of the compositional concepts that I learned with large format cameras.

Next week I will return to Death Valley with my tow buds, Alec Johnson and Travis Bechtel. Next week I will return to the scene where the landscape photography “light” was turned on. The weather forecast looks great and I will be with two good friends. How much better can it get. In my mind this is what photography is really all about. Oh to be sure, I do like to be in these beautiful places. There will be no argument there. But to be out and sharing the experience with good friends is the driving force. Photography has brought me many joys. But it is this connection to the community at large that has been the biggest draw. It took years for me to understand this concept. And over on G+ it just gets better and better. But don’t worry I will still bring new images here, to this forum.

As the holidays approach I wish each and everyone of you good cheer. I appreciate in so many ways each and every visitor to this site. I started this blog two years ago to help promote my website. Along the way however I found out that I actually have a voice. The blog has helped my with that discovery and was the first step in connecting to the larger community as a whole. I thank all of you for visiting and supporting this site.

Technical Details: This image was shot with a Canham 4 x 5 Field Camera fitted with a Schneider 90mm XL Lens. The image was shot with Fuji Velvia 50 film at f22 for 8 seconds. I used a Singh-Ray 3-Stop, Soft Edge Split Neutral Density Filter in the sky to balance out the exposure.

I’ll see you back here in the new year.

Mountain Ash at Bear Rocks, Dolly Sods Wilderness, West Virginia.

Hi everyone and welcome to today’s post. I am slipping out tomorrow for a little day shooting trip up in the West Virginia Highlands. The last few days have been spent setting up my new Epson 3880 printer and the usual other sundry tasks that confront today’s digital photographers. To be quite honest I am suffering from a little cabin fever and there is no better cure, at least for me, than shooting.

Today’s image was shot a few weeks ago in the Dolly Sods Wilderness of West Virginia. As twilight descended upon the scene I cam across this beautiful Mountain Ash clinging for all its life to the rocky soil. At this time of the year the bright red seed heads provide a stunning spark of color to the gray, drab landscape. This is a harsh world along the Allegheny Front. Plants are constantly beaten by winds that dictate their shapes and in what direction they will grow. Torqued and twisted the plants nonetheless remain defiant in the face of such harsh conditions. Humans I do believe would not fare as well living here. The wind alone, relentless and unforgiving, would drive most off the mountain. But there is also a loneliness here that would suck out the life of all but the hardiest of people. I have camped on the mountain when the wind blew. There was no comfort in the sirens song that night. Only a cold and howling tune that would not stop.

But there are times when the wind subsides. Even the wind needs a rest. And on this beautiful fall twilight evening a calm lay across the front allowing one time to enjoy the subtle treasures of the landscape; lichen covered sandstone, mountain ash, huckleberries, cranberries bogs, spruce, and expansive vistas. Twilight light, blue and cool, illuminates the white rocks revealing patterns and textures painted by lichens. The leaves of summer are long gone now replaced by gnarled stems and branches twisted and huddled together. But I know the wind will return and with it a heartless cold. The plants will dig in and brace against the impact. Winter will soon descend upon the mountain covering the land in a deep snow. Another insult, like the wind, that makes life difficult. Spring will come though and with it the thaw that beings new life and growth. This is the way it is at 4000 feet. Spring will come but we will just have to wait.

Technical Details: The image was shot with a Nikon D3x and a Nikkor 17-35mm lens at 20mm. Image exposed at ISO 100 at f11 for 1/2 of a second. I used a 3-stop Singh-Ray, soft-edge split neutral density filter over the sky to balance out the exposure.

Thnaks for stopping by today.

Dawn Sky No. 1 and West Virginia Farmland. Shot near Shepherdstown, WV.

Hi everyone and welcome to today’s post. Over the last few weeks we have had some incredible “cloud events” here in the eastern panhandle of West Virginia. I am fortunate to have a beautiful drive to my office. It winds through rural land plowed and planted with corn, winter wheat, soybeans, and other crops. On many mornings a misty fog settles into the low spots obscuring the landscape like a veil. From the high points in the road I can see the mountains of Loudoun Heights, and farther still, the water gap at Harpers Ferry, where the Shenandoah and Potomac join together.

On these crisp, fall mornings, the air is razor clear. The cool mornings coupled with the fog bring a hard rime that coats the land with a white ice. Everything seems crisp and clean; sharp with the expectations of a new day. With my morning coffee I breath in the day, gazing upward to see what treasures the sky holds. Most days are clear with maybe a passing wisp of cirrus clouds. Nothing spectacular really. Just another beautiful day in the panhandle. On this day if was different. Off to the east the first rays from the sun were just peeking over the horizon. The clouds hung low moving slowly on high winds. I just thought it was going to be special. On these days I always have the camera pack ready; batteries charged, cards loaded, camera settings dialed in. And don’t forget the tripod. I hit the road to my favorite cornfield. I arrived as the eastern light came alive. The clouds were slung low along the horizon, rising upwards, soft like flowing silk on the wind. The light hit bringing color and form to the sky. Everywhere I looked the clouds expanded over me like a shifting aurora of pulsing mist.

The corn, freshly cut, stood at attention; the long, even rows of cut stalks marching into the horizon. Overhead the clouds continued to morph into continuously changing organic shapes. It was like an unseen artist created pastel paintings and hung them in the sky. I barely changed camera positions opting instead to simply rotate the camera or switch from horizontal to vertical orientations as I composed on the fly. On this day it was all about the sky. I kept the fields low in the composition to expand the idea of the sky and how it dwarfs the landscape. The show proceeded from Act to Act with a final bow as dawn color faded bringing the high contrast light of the new day.

Dawn Sky No. 2 and West Virginia Farmland near Shepherdstown, WV.

Technical Information: The image was shot with a Nikon D3x and a Nikkor 17-35mm at 17mm. Dawn Sky No. 1 was shot in one exposure at ISO 100 at f11 for 1/2 of a second. I used a Singh-Ray, 3-stop, hard edge split neutral density filter to balance out the exposure. Dawn Sky No. 2 was shot in three exposures and blended in Photoshop.

Tidal Pool and Sea Stacks, Bandon Beach, Oregon. Image shot with a Nikon D3x and a Nikkor 17-35mm lens at 24mm. Image exposed at ISO 100 at f11 for 1.5 seconds.

Hi everyone and welcome to today’s post. Today’s image was shot at Bandon Beach along the beautiful Oregon coastline. I only had time for two shooting sessions at Bandon-afternoon/evening and sunrise. I arrived at Bandon in the early afternoon to a howling gale, high tide, and blowing sand from dunes along the back of the beach. I was hoping to get some dramatic clouds to work into my compositions but I was greeted with clear skies. Scouting for possible shots was a challenge in the contrasty light and I was constantly pelted by sand and debris. I was already tired from the drive and found the beach’s welcome less than hospitable. When you feel this way it is best to back off and just breath a bit. I went back to the hotel to check the weather conditions and the hotel owner told me that the wind would abate for the evening. He promised.

And indeed the wind died. The tide rolled out and left an expansive beach full of tidal pools and amazing rocks covered in mussels and starfish. Though I was hoping for some dramatic clouds I was treated to some amazing pink and magenta twilight light. I found this rock encircled in a tidal pool and set against a back drop of illuminated sea stacks. In the far distance you can see “Face Rock” lying in repose in the Pacific Ocean.

Tidal Pool and Sea Stacks. The Processed RAW file brought into Photoshop.

Technical Details: I used a Singh-Ray 3-Stop, Soft Edge, Split Neutral Density filter to balance the light. The WB was set to 5500K. RAW processing was done in Lightroom with final finishing in Photoshop. Take a look at the RAW file below and you can see the dramatic changes achieved through layer manipulations in Photoshop. The images below illustrate the starting point and some of the details from my processing to achieve the final image.

I almost always start with a Cleaning Layer. I perform some digital gardening in Lightroom but deal with the more difficult spots with the Cloning Tools on a separate layer. I dealt with some color cast issues in the next Layer. Keep in mind that with my first layers I am almost always dealing with Global Image Adjustments. My Detail Image Adjustments are made after Global. So for the color cast I felt the file was a bit too magenta and this was killing off some of the blues in the shot. I used a Curve Layer and adjusted the Red Curve and made a further correction in a Selective Color Layer.

Tidal Pool and Sea Stacks. Images zones worked to achieve the final image.

At this point I began looking at my more specific Detail Image Adjustments based on final vision for the file. In Area 1. I wanted to make some very specific adjustments to bring out the Contrast, Luminosity, and Color in the sea stacks. In Area 2. I wanted to bring out the Contrast, Luminosity, and Color in the rock. And in Area 3. I wanted to make a global Color change to the pool and pick out some minute details.

For Area 1. I used tow Curve Layers, one for increasing the Contrast and one for increasing the Luminosity. By Contrast I am referring to the relative difference between Darks, Midtones, and Lights. Here I am simply making subtle adjustments to the  3/4  Points (darks) Mid Tone Point, and the 1/4 Point (lights). Essentially I am making a slight “S” Curve. For Luminosity I am referring to the overall brightness. This is achieved with another Curve Layer where I am sliding the White Point over towards the Mid Point (see the screen captures below for the dramatic effect this achieves. Since I only want to apply the effect locally I use a Black Layer Mask and paint through to reveal the change.

Screen Shot of the Luminosity Adjustment Layer.

The screen shot below shows the Luminosity Layer turned on to reveal the dramatic difference to the overall brightness of the sea stacks. You will also notice the difference in the sea stack reflection in the water. Painting in the change on the foreground rock also dramatically raised the level of brightness and detail. I had what I needed in overall Contrast and Luminosity so I added a Mid Tone Contrast Layer. This is essentially a targeted High Pass Filter Layer applied to the Mid Tone components of the

Scree Shot of the Luminosity Adjustment Layer turned on to show results.

file. You can search my site for posts on how to make this layer. This was followed by Creative Sharpening applied to a “Merge Visible” Layer. Both this layer and the Mid Tone Contrast are essentially tweaking out contrast against the edges to increase the apparent sharpness of the image. The last piece of the work flow are my Dodge and Burn and Color Burn Layers. I dodge and burn my files extensively. It is essentially painting with light and dark on an Overlay Layer with a 50% Fill. Using a soft brush at low opacity I paint in details where light and shadow meet. It is a painting layer that sculpts the file.

The Color Burn Layer is where I can add and intensify the colors of the files. I have written a post on this as well. Please search the site for the details on how to perform this technique. Hopefully this post has given you some insight as to how I processed this image and some of the various techniques I use to achieve the results.

Glen Avon Falls No. 5, Beaver River, North Shore of Lake Superior. Shot with a Nikon D3x and a Nikkor 28-70mm lens at 35mm. See article for exposure details.

Hi everyone and welcome to today’s post. I am continuing to pour through images from the Lake Superior Workshop and keep finding hidden gems in some of my second tier selects. And though I know some of you may be getting tired of waterfalls I had to post this new image I processed over the weekend (But here is warning. I have some neat shots of two waterfalls from Crater Lake but I promise to hold off on those for at least a few posts). In any event today’s image was not included in my first edits for processing. One reason for this was it was a single capture scouting shot. At the time I must not have liked something in the composition and did not make a complete bracketed set. But on a second pass the shot really jumped at out at me. Which brings up the idea of karmic capture. During scout shots I will often make many captures in a row, often in an unconscious way, looking for compositional interest. At the time I obviously saw something in this collection of rocks and water to interest me but maybe not enough to stop and fully explore the options. But karma and serendipity often work together especially in this image.

I talk a great deal in my posts about the concept of leading lines and I don’t think it will take much description for you to see these in the photograph. But there is also shape repetition, shape intersections, and strong diagonal movement coupled with a way for the viewer to enter the image and move around. There is also some interesting “rule of third” stuff going on here but this gets so beaten to death that I won’t go into it. The point I am trying to make here is that for me, while I am in this self-critique moment, this image works on so many levels. It has a beautiful line of movement and simple forms but also strong, complex compositional elements as well. I also shot it straight into the sun which makes for very dramatic light. But that dramatic light comes at a price, namely a contrast range that is difficult for the camera sensor to deal with.

Technical Details: Even though I was in a scout shot mode I was still on tripod with the camera. Most of the time I will shoot scout images off tripod but I had just finished a bracket off to my left and simply turned the camera right and aimed into the sun. I still had on my 4-Stop Sign-Ray Neutral Density filter (to increase exposure time for water motion). I made one exposure at f22 for 1/4 of a second. I stopped down to f22 to create the starburst effect with the sun. I was in Evaluative Metering Mode with a WB of 5500K. Before the shot I added +1 Exposure Compensation using the button on the Nikon.  This gave me the needed exposure to capture shadow details. I made the shot and moved on. Why I did not shoot a bracket is anyone’s guess. But the histogram was nicely placed with only clipping within the sky and sun which was to be expected. To process the shot I made two RAW conversions; one for the 3/4 to mid-tone values and a second to recover details in the trees above the river. So basically a “light” and a “dark” file that I blended in Photoshop. After merging the two files I used a series of Multiply Blend and Lighten Blend modes along with curves to finish the image.

Thanks for stopping by today. I promise to have a “non” waterfall shot next time. In fact the next one will be other-wordly.

Superior Sunset, Silver Bay, North Shore of Lake Superior. Shot with a Sony a900 and a Zeiss 24-70mm lens at 24mm. Image exposed at ISO 100 at f11 for 2 seconds.

Hi everyone and welcome to today’s post. Well folks just file this image under the heading of “insane”. I can’t remember when I have seen a sunset this incredible. I made this image two days before our Lake Superior Workshop while Alec and I were out scouting the locations. We had driven up from Minneapolis in a driving rainstorm that did not give any appearance of breaking up for the evening. I was just a little bit jet lagged and tired from my early travel and so resigned myself to an evening of rest. Oh me of little faith. By the time we had finish lunch in Duluth and began the final leg along the north shore the rain broke and we could see the beginning of possibilities.

By the time we got to Silver Bay in the late afternoon the clouds began to break up to reveal small patches of blue. As the light began to change the clouds looked like giant puffs of cotton candy as the wind carried them out over the Lake. No matter where you looked, up or down the shoreline, it was amazing. When the color came the clouds exploded, airbrushed in hues of yellow, red, orange, and magenta. The shoreline absorbed the colors and the atmosphere glowed with light. On my first visit to Lake Superior I had been given an ethereal gift. What a way to start the week.

Technical Details: The image was shot with my Sony α900 and a Zeiss 24-70mm lens at 24mm. The relative brightness in terms of stops of light was nearly the same for the lake and the upper part of the clouds but brighter along the horizon. In order to hold this correctly I used a 4-Stop Singh-Ray, Daryl Benson, Reverse Split Neutral Density Filter. This is a secret weapon that I use quite often and it is tailor-made for these light conditions. The filter is made with a darker strip on the bottom portion of the resin which fades up towards the top. It is specifically designed to hold back lighter horizon lines which can be a few stops brighter than the sky above or even the foreground. In my mind it is a must have for the filter kit. I would not leave home without it. The RAW file was processed in Light room and finished in Photoshop.

Glen Avon Falls and Trees, Beaver River, North Shore of Lake Superior. Shot with a Sony a900 and Zeiss 24-70mm lens at 50mm. Image exposed at ISO 100 at f8 for 4 seconds.

Hi everyone and welcome to today’s post. Today I am returning to an image I made on the Beaver River on the North Shore of Lake Superior. During editing I passed over this image and jumped on the more dramatic waterfall shots I took. But on a second take I think this may be the more successful image I took. On my first scout trip I picked out this grouping of trees almost immediately. The wonderful way the trunks twisted and rolled at their roots seemed to emulate the fast moving water rushing by.

Photographed in the early evening the shot required a long exposure to capture detail in the deeper part of the woods and at the same time to capture the water motion. There were not a lot of specular highlights to contend with so I did not use a polarizer. Instead I employed two of my favorite Singh-Ray Filters; a 2-stop, Soft Edge Split Neutral Density to cover the water, and a Singh-Ray 4-stop Neutral Density to add exposure time. The RAW file was processed in Lightroom and then finished in Photoshop.

Thanks for stopping by today.
