Flying Home

Lynn and I flew up to Wisconsin for a wonderful visit with Mike, Sara, and Calvin last weekend.  Just before landing back in Orlando, the sky lit up.  Lynn had the window seat and was making many photos, and she made a few for me too.

Almost home 2Almost home – a lovely sunset on our way in to Orlando from Wisconsin

Before I gave her my iPhone, I opened the Lightroom Mobile App and set the file format to RAW DNG.  When I got home I processed it in Lightroom and Photoshop.  I think it’s very nice for a grab shot through a thick window!

If you have a recent generation phone, you should look into using RAW format, especially for scenes like this.  It records much more information and gives you adjustment room in your post processing, especially when changing white balance and recovering highlights and shadows.  It’s well worth it!

We’re both a little under the weather after our trip, so that’s all I have for you this week.

Thanks for stopping by and reading my blog. Now – go make some RAW photos!

Howell Creek

Howell Branch creek starts at Lake Maitland and flows into Lake Waumpi.  From there it’s called Howell Creek as it goes through Lake Howell and then wanders east and north  to empty into Lake Jessup. It passes within a half mile of our home in Winter Springs.

I’ve driven by this spot below in Maitland many times, but didn’t realize it’s on the same waterway:

Howell Creek No. 2Howell Creek – Where it crosses Lake Howell Road.  A small dam there creates a lovely little waterfall / rapid.  I’ve driven by it for years and finally made a photo.

I never stopped before because there’s no obvious parking nearby.  But Lynn volunteered to drive me over, drop me off (and come back and pick me up too!).  So off we went…

My plan was to make a few images from down near the water with a wide angle lens, maybe up close to the dam.  But several  “No Trespassing” signs scuttled that. I stayed up on the bridge by the road and made my images from there.  I’m glad I brought my 24 – 200 mm (eq.) lens too – the reach came in handy!

Several people walked by while I was there and mentioned how pretty the view is.  They talked about wading birds and the otter family they see there.  I didn’t see any otters, but a Great Egret eventually wandered into my frame.  I was lucky it stayed still while I made a long  exposure to blur the water.  When Lynn saw the photo, she thought it needed a dark colored bird – I should’ve waited for an anhinga!

Wind caused some blurring in the leaves and Spanish moss.  I was also worried the vibration caused by trucks on the road behind me would shake my tripod and blur things.  I made several frames just in case and this one came out pretty well.

Research indicates there was a water powered mill located just up stream from this dam in the mid 1800s.  And I found an old article in the Orlando Sentinel, saying that the first dam in this spot was built around 1900. One story says residents blew up the dam during a hurricane and replaced it later.  Apparently, a more durable one was built in  the 1950s and was replaced by the current dam in 1979 when Orange County widened Howell Branch Road.

It doesn’t seem like I’ve used other photos of Howell Creek in the blog before, so I’ll end this post with two older images from closer to our home in Winter Springs.

Reprocessing a Mt. Evans Elk Herd panorama

Back in July of 2007, I wrote a post about Mt. Evans, Colorado and included this image of an Elk herd we saw there:

Elk herd near mile marker 8 on Mount Evans  (2007 version)

At that time, I was using a Nikon D80 camera and made this photo with an entry level 70-300 telephoto lens.  I remember wanting to capture as much detail as possible, so instead of making one exposure of the whole herd, I zoomed in as far as I could and made four different frames at 300mm (450mm eq.), f/5.6, 1/100 sec, and iso 100. I ran across these images in my photo archive recently and wanted to see if I could reprocess the RAW files for a better result.  I thought you might be interested in my work flow – not so you can reproduce my results, but to give you some ideas on how to process your own images.

Here is one of the original RAW files SOOC (straight out of camera).  The white balance and exposure aren’t optimum and sharpness isn’t very good either – maybe due to poor lens stabilization and optical performance (and maybe due to my poor technique).

Here are the steps I went through to reprocess this:

  • Used DxO Photo Lab software to convert from RAW to .tiff and take advantage of the built in Prime Noise reduction algorithm.  I like that this software applies camera and lens specific corrections to all images.  It also returns the results to Lightroom still in RAW / DNG format.
  • Made basic adjustments (exposure, white balance) in Lightroom, and copied to all four frames.
  • Opened as layers in PhotoShop.
  • Stitched the frames into a panorama: Edit -> Auto-align Layers; Edit -> Auto-blend Layers.  At this point, it looked like this:

When I made the original frames, I didn’t cover enough ground for a rectangular composition.  To fix this, I used PhotoShop’s excellent Content Aware Fill on the missing corners.

  • Select the blank areas with the Magic Wand tool.  Expand the selection (~3 pixels).  Edit -> Content Aware Fill
  • use the clone tool to eliminate any obvious fill anomalies.

And then I worked on sharpness.  Here is a 300% look at the area near the Bull Elk:

Not very sharp.  So I:

  • Duplicated the layer and applied the Topaz Sharpen AI filter.  I used the Stabilize method with a Remove Blur value of 0.70.  Here’s the much improved result:

Topaz Sharpen AI can work wonders on this kind of problem, but it does take a lot of CPU power.  Depending on your hardware, you might have to be (very) patient.

  • The final step in Photoshop was to use Topaz Clarity for some added midrange contrast.  I applied the Nature -> Fur and Feathers II preset.
  • Back in LightRoom: I cropped to a 2:3 format; tweaked White Balance and exposure again; boosted texture and shadows on the Elk with a circular adjustment and range mask; Reduced green and yellow saturation; Used a -12 highlight priority vignette and added grain at 15.

And this is the new version I just posted to Flickr.

Mt. Evans Elk herdMt. Evans Elk herd (2019 version) – Near mile marker 8. Quite a harem! There are about 60 elk in this image: A single bull, ~10 young ones, and the rest female.

It took me about 30 minutes to do this.  Was it worth the effort? I can’t answer for you.  I think it looks much better and I’m glad I saved those RAW files! As long as i can re-start from the original sensor data, I can leverage newer software and get better results.  I know a lot of folks don’t enjoy computer work, but I do – so to me it’s worth it.

Click on any of these to see larger versions.  I have other Mt. Evans (and Colorado) photos in this album on Flickr.  And if you have any questions on this, I’ll be happy to try and answer them.  Just ask in a comment below.

Orlando’s Lake Dixie and Lake Cherokee

MaryKate had the day off last Thursday for Independence Day and invited me to walk around Lake Dixie and Lake Cherokee with her.  I was glad to go – I’d been by before, but only inside a car and unable to take a close look.  We also wanted to check on how the cygnets she wrote about on Fathers Day are doing.

Lake CherokeeLake Cherokee

Lake Cherokee is the smaller of the two and both are lovely.  For a location in downtown Orlando they have a lot of wildlife.  Maybe I shouldn’t be surprised by this since they’re very close to Greenwood Park and Cemetery, where there’s also a lot of wildlife.

One of the first things we encountered was this Heron.  I thought at first it was a Green Heron, but got some help with the ID on Flickr.  It was small and still – and I glanced right past it without any recognition.  I’m glad MaryKate commented on it so I could make a photo!  Least Bitterns are supposed to be common in this type of environment, but I don’t  see them much.  I think because they’re so good at hiding!

Next we came up to this Mallard posing for me in the grass in front of some yellow flowers.

And there were several Wood Ducks.  I’ve seen them before at Greenwood and Mead Gardens, but hadn’t paid attention to their non breeding colors.  This young one is interesting and I’m looking forward to spring time when their plumage starts changing.

Here’s a bird that I’d never seen before or even heard of.

Swan-Goose (?)Swan Goose

Swan Geese are native to the Far East and have also been domesticated.  There were two, this one and another that was all white.  It’s likely they escaped or were released from captivity since they don’t occur naturally in the US.

This Mottled Duck was resting in a notch about seven feet above ground. It watched us as I made the photo, but didn’t seem nervous. The tree was right next to the sidewalk and it must be used to people nearby.

Unfortunately, there’s some bad news about the Lake Cherokee Mute Swan family.  There were initially three babies, but only one’s been seen lately.

From across the lake, MaryKate and I spotted two adults  but no babies.  We worried they’d lost the last cygnet too.  But when we got closer, we saw what was going on – Mom was riding the baby on her back!

We also saw Limpkins, Common Gallinules, Great Egrets, a second Mute Swan family (with four large juveniles!), Anhingas, and several turtles.  What a wonderful walk and what an unexpected abundance of things to experience and photograph!  Thanks for inviting me, MaryKate!

Morning Dew

I try to maintain a regular schedule here and normally blog once a week – almost always on Sunday morning.  I get up early and write (or finish writing) so I can hit the “publish” button before breakfast.  My system’s worked pretty well for me and I hope for readers too.  It’s gotten me up  to almost 600 articles so far.

I enjoy it, but it’s a challenge at times.  I want to include photography info worth reading or at least an image worth viewing.  And I want each post to be something that I’ll enjoy re-visiting myself.

This morning I sat here with a blank page and a photographically blank mind.  Making and processing images is a passion for me and has been for a long time.  I’m pretty sure I’ll continue to enjoy it as long as I can.  But it is just a hobby and there can be (and this week are) more important things to think about and deal with.

I won’t burden you with any personal issues – the blog is about image making.  Instead I’ll simply leave you with another recent Calladium composition that I hope you’ll enjoy. Processing it to preserve as much detail as possible took my mind off of other things for just a little while.

Now – go make some photos!  I will too.

Blue Cypress Lake Postcard

Hello loyal readers! This is the next entry in the occasional blog category called “Postcards” where I upload photos of Central Florida scenes – similar to ones you’d find on a postcard.

It’s easy to find all of these. Just use the “Places / Categories” pulldown menu over on the right side of the blog and select “Postcards”. If you’re viewing the site on a phone, you may not see that menu – in that case, just type “postcards” into the search box.

Blue Cypress ShorelineBlue Cypress Shoreline

I made this image in April of 2017 from a pontoon boat in Blue Cypress Lake, near Vero Beach, Florida.  This wonderful lake is part of the St. Johns River headwaters.  Here’s a link to all the posts I’ve written about it: https://edrosack.com/category/photo-ops-in-florida/blue-cypress-lake/.  And you can view other photos from there at this link: https://www.flickr.com/photos/edrosack/albums/72157630027829768.

It’s a 2 frame vertical panorama shot with an infrared modified camera, handheld with a 24 mm equivalent lens at f/3.5,  ISO 200 at 1/800 sec. I processed the photo and converted it to Black and White using Lightroom and Photoshop. You should be able to click on it to go to Flickr and then select the download symbol below and to the right of the photo. I hope you like it!

Merritt Island 6-9-19

It’s getting to be that time of year down here in Central Florida:  Hot, muggy, and buggy, with many of the birds hiding or gone.

None the less, Kevin K. and I went over to Merritt Island last week to see what’s going on. Our first stop was along the Indian River at the Titusville Marina.  Clouds on the horizon helped the sun add some color to the morning.

Dawn, down on the riverDawn, down on the river

On Black Point Wildlife Drive, our most interesting find was this Stilt wading through calm water and good light.  I like this close up, but I wish I’d also made a frame including the whole reflection.

As we left, this healthy looking animal was calmly marching across the black top.  There were no cars coming from either direction, so we could stop and give him the right of way.  And make a photo too!

Why did the gator cross the road?Why did the gator cross the road? It didn’t say, but the grass is green on the other side!

There are still some interesting birds at MINWR.  For instance, Pat H. found a Clapper Rail on BPWD a couple weeks ago.  But it seems like most of our winter visitors have moved on.  Maybe we need to move on too and look for photo ops in other spots until it starts cooling off again.

Red, Green, and Blue

We’ve been busy with projects lately and I haven’t been able to go out on any  photo expeditions for a few weeks.  So I thought I’d show you three recent images I’ve made close to home.

Back in the film days, one way to increase saturation was to slightly under expose.  That still works with digital and it’s what I did when I saw how the late afternoon light was hitting one of Lynn’s red Caladiums in our garden.

We were getting out of the car on the way in to a restaurant one day for lunch when I saw this lizard.  It was very calm and let me get close with my phone camera.  It didn’t need any under exposure to saturate its green color.

Very greenVery green – Anole Lizard

I shot from below the flowers and up toward the sky for this last image.  I stopped down to get as much in focus as I could and bracketed the exposure since the light was tricky.  But the camera’s dynamic range was large enough that I ended up using just the nominal exposure.

Our schedule frees up some next week, so I might try to sneak out with a camera one day.  We’ll see!

Long Exposure with Variable Neutral Density Filters

A friend wants to make long exposure photos on an upcoming trip. I recommended using a Variable Neutral Density Filter (VND) and offered to let them try mine.  So  we headed over to the Cocoa Beach Pier last Friday to test them out on some ocean waves.

Cruising homeCruising home. VND, ƒ/11, 35 mm, 0.3sec, ISO 100

VNDs are made from two polarizing filters – one’s fixed and the other rotates. You use the rotating one to vary the amount of light that’s blocked (typically between 1 or 2 and 6 or 8 stops).  I like them because they give you precise and easy control over how much light hits your sensor.  If you reduce light on the sensor, you can use a slower shutter speed or a wider aperture for a given scene.  They’re good to have when you photograph waterfalls (slow shutter to blur / smooth water) or in bright light (to shoot with a wider aperture and blur backgrounds).

Here’s my approach for smoothing water:

  1. Mount the camera on a tripod and trigger it with a remote or the self timer.
  2. Set ISO (usually for best quality). Don’t use auto ISO.  We want the  camera to vary shutter speed instead of changing ISO when the VND rotates.
  3. I use Aperture Priority mode and select the F-stop (for depth of field, image quality etc.).
  4. Compose with the VND filter at its minimum value (brightest setting).
  5. In bright light, you can use auto focus.  In dim light, you may need to  manual focus so the camera’s auto focus doesn’t hunt when you  darken the VND.
  6. Now, slowly turn / darken the VND until your shutter speed reaches the value you want.  You’ll need to experiment to find what looks best to you, but for water try between .25 and 1 second.
  7. If you can’t get a slow enough shutter, you can close down your aperture, or lower your ISO.

Some things to watch out for:

  • Like much in photography (and life!), you can find very expensive VNDs and very cheap ones. I’ve had good luck with name brand ones in the middle price range.  Don’t buy the cheap ones!  They may not be optically flat or coated, and might introduce color shift problems.  You’ll probably pay more for thinner ones too, which will reduce chances of vignetting.
  • Definitely look for VNDs with coatings to help prevent reflections / flare.  You’re adding four more air/glass interfaces to the front of your lens and you can’t use a lens hood, so coatings will improve performance.
  • Since these filters can be expensive, I recommend buying only one, sized to fit the biggest diameter lens you’ll use it with.  I have a 77mm VND and step down rings to mount it on my smaller lenses.
  • Some VNDs can be rotated too far and will show an ugly cross-shaped anomaly.  If yours does this, watch for it and back off until it disappears.  Some are made with a stop so you can’t rotate them too far.
  • Check your results as you go.  It’s easy to over expose highlights in moving water, so you may need to dial in some negative exposure composition.  Also, if the light getting through is too dim, your camera’s meter may not work well.  In that case you’ll have to change to manual exposure and adjust accordingly.
  • Make several exposures at different shutter speeds so you’ll have distinct looks to choose from when you get home.

That’s it – simple, right?  Do you use VNDs?  If so, let me know where I can view your long exposure photos.  And if you have any hints of your own, please share in a comment for everyone.
