Return to Seaworld

We went to Seaworld again at the invitation of the United Way group here in Orlando.  They very graciously organize the visit each year to thank people that contribute to the charity.  We almost didn’t go due to the weather.

There was a cold front coming through with a strong line of showers ahead of it. When we got out of bed, it was north of us but moving south fast. We decided we’d go anyway and timed our arrival for just after the rain came through. The park wasn’t very crowded. I think the weather discouraged many people from going.  As you can see above, it cleared up nicely.

We’re not into roller coasters any more so we didn’t do many of the rides and spent most of our time just walking. I practiced with the D7000 and a wide angle lens. The photo above was made at an 8mm focal length – it’s a challenge to frame a scene with an 8mm lens and not have everything tilt in from the edges.

Here’s a couple more from yesterday.

Circle B Bar Reserve – Lakeland, Florida

Intro / Description

This nature wonderland in Lakeland, Florida is named after a cattle ranch that used to exist on the property. It was purchased by Polk County and the SW Florida Water Management District in late 2000. The area is 1,267 acres total and starting in 2005, 400 acres have undergone a marsh reclamation to recreate a natural habitat and food source for many kinds of resident and migrating birds and wildlife. The Circle B is also home to the Polk County Nature Discovery Center.

Lake Hancock - western shore

Circle B has a tremendous variety and number of birds. Alligators also inhabit Lake Hancock and can be seen from the trails in several places. There are a variety of different areas on the property including Oak hammock, freshwater marsh, hardwood swamp and the lake shore.

The Circle B has over 7 miles of marked trails for walking or biking. If you go, make sure you see at least the Alligator Alley and Marsh Rabbit Run trails. We hiked these as well as the Shady Oak, Windmill Whisper and portions of Wading Bird Way and Eagle Roost trails when we were there for a total hike of more than 5 miles.

In our one visit we saw Great Blue Herons, Great Egrets, Ibises, Cattle Egrets, Ospreys, Red Shoulder Hawks, Cormorants, Anhingas, Limpkins, Whistling Ducks, Alligators, Turtles, a very brave rabbit and some other things as well. One local photographer we spoke with told us about a Barred Owl in the area as well as some otters, but we never saw them. Next time!

Cormorant

Cormorant – These birds have been posing for me lately.

In addition to the wildlife, the scenery is quite beautiful and different from our normal areas near the coast. There were many types of trees and flowers, including this sunflower variety that was very abundant all over the property.

Marsh flower close up - sunflower?

These sunflowers (?) were all over the Circle B Bar Reserve – very pretty. I wonder if they bloom all the time or if we just happened to be there when they’re in season?

Info for Photographers

Photo hints:

I’ve only been to the Circle B once, and need to go several more times to get an idea of how consistent the photo ops there are. If you have the kind of experience we did, you’ll have lots of opportunity for photos of still as well as in-flight birds. If you’re quiet as you walk, you can avoid scaring off the nearby birds and get some better shots. They are somewhat used to people here, but not overly tolerant. Make sure you look all around as you hike (especially up) and take an occasional glance behind to see if you’ve missed anything.

In addition to my photo set from the Circle B, visit the Circle B bar group on Flickr to see what others are photographing there and to read up on discussions about the reserve.

Tripod/Monopod:

Allowed, of course. Tripods would be very handy for landscape photos or (with a gimbal head) for birds. You’ll have to decide how much gear you’re willing to carry on your hike. Since this was a scouting trip, we traveled light and I wished several times that I’d brought my tripod.

Lenses:

Telephoto for birds / wildlife and and wide-angle for landscapes. You’ll need a good range of lenses to cover everything here, but you’ll be able to get some good photos no matter which lens you have with you.

Best time to visit:

As for any place when looking for birds and wildlife, early in the day (or late) is best. I’m not yet sure what times of year are the best here, but mid to late November is definitely worth a visit.

Other:

You’ll be walking a good bit. Make sure you wear comfortable shoes and bring some water with you.

Local Park Landscapes

Just a short post today with an idea for local photo-ops:  How about the parks in your own neighborhood?

I wanted to try out the D7000 on some landscape photos, but didn’t really have time to go anywhere special.  Instead, I went out to three local parks and made the photos below.

You’ve seen this tree before – it’s along the shore of Lake Jesup in Central Winds Park.    I like this more complete composition, since it includes the cyprus knees.

Cyprus tree and knees

This next one was made at Lake Marie in Trotwood Park.  There are almost always at least a few birds in this small lake and last night was no exception.

And finally, here’s one from this morning at Sam Smith Park.  It was very quiet – almost no wind, which helps wonderfully with reflections in water. The cyprus trees here in Florida do change colors for the winter – the one on the left is starting to turn.

Gatorland cancels early entry program

Update (1/8/2012):  Gatorland has re-instated their photo pass.  See their blog post here.

Gatorland in Orlando announced on their Blog that they’re canceling the 2011 Photographers Pass Program.  This is very unfortunate for bird photographers, since the early entry / stay late times are during the best light of the day and when there are no “civilian” crowds.

The Alligator Farm in St. Augustine has issued an announcement in response on their mailing list saying that they will continue their Photo Pass / early entry program.

I’ve updated my post comparing Gatorland to the St. Augustine Alligator Farm as I think having a photo pass gives the  Alligator Farm a strong advantage for photography.

There’s some discussion of this on Flickr in the Gatorland Group (this discussion has since been deleted).

Sunrise, Otter, Eagle, Cormorants, Raccoon – a nice morning at Viera Wetlands

I’m coming down with another cold and wasn’t very enthusiastic about going to Viera Wetlands yesterday. Actually, “not very enthusiastic” is a big understatement. I almost didn’t get out of bed – but now I’m glad I did.

We had to leave at “O dark thirty” to get to the west side of the wetlands just before sunrise. I wanted to try the D7000 out on landscapes and it performed very well. The image below is a single exposure of the sunrise. I don’t care too much for silhouettes – I like to have some detail and color in the shadows. For this one, I exposed at -2 EV to prevent blowing out the sky and then brought up the shadows in post processing. The D7000 recorded a very broad dynamic range and has remarkably little noise in the shadows at base ISO, even when under exposed. This real world example, along with the the results from the recent DxOMark test of the D7000 indicate it’s going to be a very fine landscape camera. The only problem is that I don’t have a very wide lens for it.

Sunrise at Viera WetlandsSunrise at Viera Wetlands, D7000, ISO 100, 1/100 sec. @ f/11, 16 mm

As we were photographing the sunrise, an otter swam by right in front of us just past those reeds (about 8 – 10 feet away). That’s the closest one’s ever come to me in the wild. Of course, I didn’t have the right camera set up so I didn’t get a photo. I think the otter knew that, and swam by just to tease us. We saw it a couple more times but could never get a shot off. Those things are quick. And black. And hard to photograph.

After the sun was up, we drove around the wetlands and came up on this:

This eagle was just surveying the area. I did get a few images when it flew off, but none blog worthy. I need more Birds in Flight practice, especially at 500mm!

The sun was up, but still low in the sky as we saw some cormorants sitting on a viewing platform. The light was hitting this one just right to show off the detail in his dark feathers.

Here’s one more photo I want to show you. This little fellow was digging around in the reeds along with several birds. I’m not sure what they were after, but it might have been snails – we saw a lot of them yesterday. This image is a good example of the D7000 at ISO 1600. Very usable with minimal noise.

Today I feel a bit worse, so I’m glad I went out yesterday. Hopefully I’ll start feeling better tomorrow.

Macro photography – D7000 or D700?

There are many kinds of photography. I tend towards landscapes, birds & wildlife, and sometimes macro. When I was using a Nikon D90 and a D700, it was pretty easy to decide which camera to use for what. They had roughly the same number of pixels and well known ISO performance. I would use the D90 as my primary bird and wildlife photography body (especially in good light), and the D700 for almost everything else.

Now that I’ve swapped the D90 for a D7000, these questions have become a little harder to answer. The D7000 has better ISO performance than the D90, and more pixels than the D90 or the D700. Clearly, the D7000 is still a very good first choice for bird & wildlife (unless they’re especially cooperative and close), even more so than the D90 because of its improved autofocus and resolution. And in dim light, the D7000’s ISO performance should make it even more useful than the D90, although not as good as the D700. Using the camera now for a couple of weeks has confirmed all this.

But what about landscape photography and macros? This isn’t as easy a question. They’re most often done with a tripod and therefore ISO performance isn’t a factor, so you can use the camera’s base / optimum ISO (D7000 @ ISO 100, D700 @ ISO 200). Which body to use probably comes down to magnification and depth of field vs. diffraction. I hadn’t had a chance to explore using the D7000 for macros, so I decided to do a little experiment today.

My subject is a rosebud from our front garden (by the way, if you know what kind of bugs those are on our rose bush, let me know). The setup was fairly simple: Tripod mounted camera, using the Nikon 105mm f/2.8 VR macro, and a Neewer LED ring light with the rose against a black background. I used matrix metering, with an exposure bias of -3EV to avoid blowing out the red channel (every digital camera I’ve owned – including the D7000, has overexposed red roses). I tried to keep the positions / setup as close as possible but unfortunately, I had to go back and re-take the D700 photo and it isn’t exactly positioned the same. I used an aperture of f/11 with the D7000 and f/16 with the D700, since those values should give the most depth of field without any degradation due to diffraction. I also used the cameras’ base ISO settings. I then ran the two photos through Capture NX2 with the exact same adjustments ( daylight White Balance, vivid Color Control, Noise Reduction off, and Unsharp Mask set to 30/5/2) and created a .jpg of each.

Rosebud:  D7000, ISO 100, Nikon 105mm macro, 1/20 sec @ f/11Rosebud: D7000, ISO 100, Nikon 105mm macro, 1/20 sec @ f/11

Rosebud:  D700, ISO 200, Nikon 105mm macro, 1/13 sec @ f/16Rosebud: D700, ISO 200, Nikon 105mm macro, 1/13 sec @ f/16

So what conclusions did I draw from this? With a sharp lens, using base ISO, the D7000 makes full use of all of it’s pixels and therefore has very good resolution when compared to the D700. For macro photography, the extra magnification, pixels, and increased apparent depth of field will almost always be an advantage. So my first choice for macro photography now will be the D7000.

What about landscapes? That adds a couple more things to consider (e.g. dynamic range, field of view), so it needs some additional thought and experimentation. I’ll let you know what I find out.

Overcoming shallow depth of field

A pair of Great Egrets in the lilly padsA pair of Great Egrets in the Lilly Pads

I was at Viera Wetlands yesterday and came up on this scene.  The pair of birds was about 30 feet away and  I was using a long telephoto lens (Sigma 150 – 500 OS, @ 500mm) and shooting hand held.  To keep my shutter speed high (1/1000 sec), I had my aperture set to f/8.

Under these conditions, the depth of field (DOF) was so shallow (about 6 inches) that I couldn’t get both birds in focus at the same time.  I could have stopped down to f/16, which would increase the DOF to about 12 inches, but that still might not have been enough – and the risk of motion blur would increase when the shutter speed slowed down.

So how can you overcome such shallow depth of field? Here’s how I did it:

  1. Make two exposures, one focused on the front bird and one focused on the rear one.
  2. In Lightroom, do your preliminary adjustments  so the images’ appearance matches as closely as possible.  You want to keep the background around the birds as similar as possible in the two images.
  3. Open both in Photoshop, and move them into a single file as layers.  Put the base image (the one with the front bird in focus) in the background layer.  The top layer then has the rear bird in focus.
  4. Select both layers and use the Edit/Auto-Align Layers to line things up.
  5. Insert a Layer Mask (hide all) on the top layer.
  6. Now you’re all set to paint the in focus rear bird into the image with the front one in focus.  Select the layer mask and use a white brush color to paint the rear bird in.  If you make a mistake or need to back something out you can change your brush color to black to erase the top layer.  You can also play with the brush hardness and opacity to feather things in.
  7. Once you’re happy with the result, flatten the image and make your final adjustments.

“But Ed,” you say “isn’t this cheating?”  It depends.  If you’re a photojournalist reporting on Great Egrets in Viera Wetlands and how close they often come to each other, then yes it might be.  Journalists must meet ethical standards.  On the artistic side, you’re trying to represent what your eyes (which have a greater DOF) or mind sees.  So in this situation it isn’t cheating.  You’re using the tools available to make the image you want.

“But Ed,” you say “this is too much work!”  It depends.  Some images are worth the effort and many are not.  There’s software you can buy to automate this sort of thing for you.  Photoshop can do it too. But the automated software requires very careful set up and in most cases a tripod, and many exposures with small changes in focus for each one.  In this situation, I only needed two photos, one for each bird.  Alignment between the images isn’t critical since I’m only using a small portion of the second one.  So it’s fairly easy to show the pair of Egrets and not be distracted by having one out of focus.

You can see more of my Viera Wetlands photos in this set on Flickr.

For comparison, here’s the original photo straight out of the camera:

Quite a dramatic change, and for me worth the effort.  What do you think?

High ISO performance of the Nikon D7000 vs. the D90 and the D700

You’ll have to pardon me, but I’m going to take a short photo op break and geek out a little bit on camera gear.

Today, Adobe came out with a release candidate of Adobe Camera Raw that will process  D7000 RAW files.  I ran a quick test to see how this new camera  compares with the D90 and the D700.

I’ve put together a composite image below, which shows roughly the same scene photographed with each camera.  I kept everything as constant as possible (e.g camera position, light, lens).  The D90 is on the top at ISO 3200.  The D7000 is in the middle at ISO 6400.  And the D700 is on the bottom, also at ISO 6400.

I processed all three images with a zero preset in ACR and then adjusted only the exposure / fill light and tone to make them look roughly similar.  I left all sharpening and noise controls set to zero (off).

Judging by this pseudo-rigorous test, the ISO performance of the D7000 appears to be in between the D90 and the D700.  It looks about the same at ISO 6400 as the D90 does at ISO 3200 (e.g. ~1 stop better).  Noise is not as low as the D700, but resolution looks better.

I’ve put this and other D7000 images in this set on Flickr.  All of them are in high resolution so that you can better judge the image / camera quality.  You can also click on the image below to go directly to it on Flickr.  For any of these, select “Actions / View All Sizes” to see much larger versions of the photos and judge for yourself.

Additional Nikon D7000 Samples at Viera Wetlands

Lynn and I went out to Viera Wetlands this morning to survey the wildlife that’s around and so I could get a little more field testing in on the Nikon D7000.  Once again, this great birding spot didn’t disappoint us and although the activity and number of birds were down a bit from their peak during the nesting season, we found plenty to see and photograph.

I’m shooting the D7000 in RAW & fine jpg mode, but using only using the jpg files until later when RAW is supported by ACR and Nikon CaptureNX2.  So far, it’s definitely living up to my expectations.  The combination of more pixels and improved sensitivity is a great for bird photography.  Here’s one shot I did early in the morning, before the almost full moon set:

Great Egret, Ibis, and MoonGreat Egret, Ibis, and Moon, Nikon D7000, ISO 100

On this photo, I cheated a bit. The depth of field on the Sigma 150 – 500 @ 500mm and f/7.1 is too shallow to hold the moon in focus along with the tree and birds.  So I made a second exposure focused on the moon and masked it in using Photoshop.

I set up the camera in auto-ISO mode and let it respond to the varying lighting conditions so that I could see how it performed over a range of ISO sensitivities.  At ISOs up to 1000, there is very little noise.  I need to do some comparisons with RAW files, but so far, it looks to me like the ISO performance of the D7000 is at least a 1/2 stop better than the D90.  Here is one example from today at ISO 900:

Here is another, un-cropped photo of a Great Blue Heron:

One of the comments on these photos today on Flickr was “You’re lucky to be in an area with amazing wildlife.”  I couldn’t agree more.  And that’s just one of the many ways that I am so very lucky.

You can click on the photos above to view them on Flickr.  I’ve also uploaded several more in this D7000 set on Flickr (sorry, no longer available). Many of them are in high-resolution so that you can better judge the image / camera quality.  You can also view more photos I’ve made at Viera Wetlands here in this set.

Nikon D7000 Sample Images

So far, I’m very pleased with the Nikon D7000. I’ve posted a few sample photos on Flickr in this set (sorry, no longer available).  They were all uploaded at full resolution and all but this one of a very cooperative Red-Shouldered Hawk are un-cropped.

Red-shouldered Hawk, D7000 at ISO 220, full resolution, cropped

Red-shouldered Hawk, D7000 at ISO 220

I haven’t had a chance to do any direct comparisons, but the D7000 results seem very good all the way up to ISOs above 1000.  With the D90 I’ve been reluctant to use anything above ISO 800.

The photos I’ve posted so far were all made in JPG.  I took them in RAW+JPG mode, but so far Adobe Camera Raw and Nikon  CaptureNX2 can not process the RAW files.  To do a real comparison of the performance at different ISOs, I’d like to use the RAW files without any adjustments.  A project for another day.
