columbus skyline

Skyline of Columbus Ohio

I was off teaching outside of Columbus, Ohio in Dublin this past weekend. These days when I travel for business, I try to schedule some time for doing some photography on either side of the event. Weather doesn’t always work out for the best as plans are made in advance! But you take what you can get.

I was planning on photographing the Columbus skyline from the bridge at night with the river reflection. There were recent floods which left the banks mud-stained, the wind was blowing about twenty mph and, the skies were less than desirable. Other than that it was excellent! ; )>

The nasty weather didn’t stop me from making a few images from the area. I got to the Main Street Bridge and did the best I could. I’m still testing the Lumix G9 and its 80MP capabilities, and it impresses me.

I thought it might be fun to try and get the bridge in the foreground with the city in the background through the supports.

This image shows that capturing a moving subject during the exposure is not such a great idea. Or is it? I’m thinking about some creative possibilities in making a scene be devoid of people. Or just giving the hint of people in a scene. What about water photographed with a slow shutter speed?

I’ll be playing (er I mean working with) this large MP capture feature and let you know how it works out. If you’ve got any thoughts, ideas or examples of your testing, this feature, let me know.

Blackwater National Wildlife Refuge

Last week I was speaking at the Maryland Professional Photographers Association. It was a great group, and we made a solid connection in what became an all-day program due to weather conditions that were a wee bit unusual for this time of year.

For this trip, I scheduled some extra time to get out and photograph wildlife. I had an excellent guide and companion for the shooting days in Chris Paulis! (check out Chris’ work here) Chris and I had a blast looking for photo opportunities in the area. On Friday we drove two hours each way to spend time at the Blackwater National Wildlife Refuge. Chris had mentioned he hadn’t had a lot of luck there in the past, but I think we did pretty well. We made the loop through the refuge eight or nine times discovering different wildlife situations on each cycle.

The majority of my images were captured with the Lumix GH5 (currently $200 off for a limited time) and the Lumix G Leica 100-400mm lens. Chris had the same lens and was shooting with the new stills flagship camera the Lumix G9. (mine came in right after I returned from the trip. More to come about that new camera)

I enjoy wildlife photography, and my goal is to have images that show either beautiful lighting or behavior images. I’ll share some below and in another post or two over the next week.

gret blue herons bob coates photographyStill environmental, this image has a bit more behavior. I laughingly title this Heron Airport.

gret blue heron bob coates photographyIt’s all about the light and shadow. Add in some lovely water reflections, and now we’re cooking. Getting photographs like this take time and patience. There are only a few minutes in the morning and afternoon when the light starts to work like this. And then there’s having the performer in place at the same time as the light.

Next time some intimate portraits of my heron budies. Til then go get ya some great photo ops!

photography exposure rules

Photography “Exposure Rules”

This post was inspired by questions about getting a solid exposure of the moon with detail. Many photographers have issues with this. We’ll start with the ‘Sunny 16 Rule’. Note that I put the exposure rules in quotes in the title of this post. That’s because technically there are no rules because any exposure is the correct exposure if it helps to tell the story you are trying to share.

No matter who tells you something it is always important to test for yourself. ALWAYS! (example below)

The exposure rules I’m going to share here can get you to a place where you can start your journey and attain an exposure that will render highlights and shadows visible within an acceptable range without losing detail in either one. Once you know this happy place, it can be a handy starting place and to check your metering equipment in your camera and light meter.

sedona sunny 16 photo ruleThe Sunny 16 Rule in action with Sedona’s red rocks. Lumix GH5 with 12-60mm Leica
Exposure settings f16 1/400th second at ISO 400

The first rule is the Sunny 16 Rule. On a sunny, cloudless day scene, this rule states that if you set your camera to f16 and your shutter speed to 1 over your ISO setting you will get a proper exposure. If your ISO is set to 400, your settings would be f16 at 1/400th of a second. It will be correct. For additional creative control within the rule just keep the ratios between shutter speed and f-stop. If you want a shallower depth of field, for each change in aperture change the shutter speed. f8 is two stops different from f16, so the shutter speed would need to be 1/1600th second with our 400 ISO setting. Be aware that small tweaks in 1/3rd of a stop can make quite a difference in how the scene renders. A slight underexposure

Let’s move to the moon. I shared a piece of info I was told without testing. (sorry about that! working to rectify it ASAP) I was told we could use the ‘Moony 11’ the same way we use the Sunny 16 rule. I apologize for passing that info on without testing first. After testing, I found that the reality for getting a nice exposure of the moon was the ‘Moony 8 Rule’. Set your aperture for f8 and use the reciprocal of your ISO for your settings. Even though the moon is a reflection of the sun, it is traveling through a couple of layers of atmosphere and absorbing some of the light itself. It turns out Moony 8 seems to be the way to go.

moon with clouds imageLight clouds crossed the moon and changed the exposure to 1/60th of a second still at ISO 400

While the Sunny 16 rule is for the exposure of the scene lit by the sun. The Moony 8 is to achieve texture on the moon itself.

6K Photo Mode post Focus – Lumix GH5

Ran into a very interesting phenomenon pointed out by my wife. She was working in the yard and saw these long strands of moving stuff. (tech talk here) Never saw anything like it. Turns out it was tens of thousands of Gnat larva on a migration.

I wanted to get a shot of the larva to help identify it. Grabbed the GH5, my Leica 45mm Macro-Elmarit f2.8 lens, and a small tripod and was having no success. Even at 6400 ISO I couldn’t get a sharp photo of the moving, writhing masses due to the macro lens and speed with which the larva was moving.

I decided to try the Post Focus Photo Mode just to see if it could help. The photo mode uses all 225 focus points in the camera and captures them in a 6K video. Each of those 225 frames can be pulled and processed into an eighteen meg-pixel photo. The intended use in the beginning was to allow the user to decide which focus point to use later. An addition to the mode is the ability to fuse all the frames together giving you just the sharpest bits. The beauty is this can be processed in camera. Focus stacking in camera! Able to give you a 50MB plus file.

Even though this was a moving mass because each focus point is being photographed separately it is stopped and in focus. When all the images are processed together I get a Depth of Field i couldn’t with a single capture it also processed the sharp areas into a still image even though there was lots of movement.

The new technology can be leveraged in many ways to make it possible to create images in a different way.

I’m diggin’ it!!

International Photographic Competition 2017 – Artist Category

You can check out the post from yesterday about my Photographic Open entries in the Professional Photographers of America IPC competition. In that post you will also see the elements that the judges use to make their determinations on scoring. In the Artist category those twelve elements are also an important part of the judging but there is additional criteria that has to do with how much work and the difficulty of it that goes into the creation of the image.

You will notice there are small reference images on the canvas. These are there to help the judges understand the starting point of the art. This helps them see the amount of work that went into the creation of the final piece.

Without further ado, here are my Artist entries.

wall of fame photo ipcWall of Fame – Artist entry. This image scored a 93 at District and unfortunately did not make it to the PPA Loan Collection. This particular image needs a champion and sees the amount of work that is required for each individual image, let alone the collection.

homage to salvador daliFull Moon Over Dali Swamp – This was a personal favorite as I created an homage to Salvadore Dali. The image started to evolve in my head while photographing at the Bosque Del Apache Wildlife Preserve. Seeing that tree in the water at the bottom of the reference images was the catalyst.

Iris artist submissionIris – Started with a ‘focus-stacked’ image of an iris and I then used Adobe Photoshop to paint the resulting image.

grand openingGrand Opening – This image was photographed and processed as above.

I have been participating in imaging competition for eighteen years and feel that it has been on of the most important parts of my education. The process gives you feedback on your work from professional image makers. This feedback and attention to detail force you to stretch and improve.
