Home for the Holidays

It’s getting chilly outside, presents are starting to show up,  and we’re hearing carols on the radio.  Family and friends are arriving soon and before we know it, It’s a Wonderful Life will be on TV around the clock.  Whether you celebrate Christmas or another winter holiday, family gatherings are the greatest photo-op of the year!

Mom, me, Dad – Christmas, 1955

Gather folks up and make photos and maybe even some video.  Include everyone and  make sure you get yourself into a few.   Don’t put it off and don’t take no for an answer. Technical perfection isn’t even required.  You and people you love will cherish the photos anyway.

Thanks for stopping by and reading my blog.  Now – go make some family photos! And share them – someone will be very glad you did!

A day in Nassau

Lynn and I took a short cruise on Holland America’s Nieuw Amsterdam starting last weekend. One highlight was a full day spent in Nassau.

This is an image heavy post, so I apologize if you’re on a slow connection. I’ll let the photos and captions tell the story.

Nassau sunriseSunrise arrival:  Docking at 8am made for a nice view as we pulled in.

Lynn booked us on the Bites of Nassau Food Tasting & Cultural Walking Tour. (please click on their link for details).

Although I don’t have any more images to show you (thank goodness, right?),  we also  visited the Athena Cafe & Bar and the Tortuga Gift Shop & Rum Cake Bakery.

You might not consider Nassau a “Central Florida Photo Op”, but I do.  It’s one of many places that are very accessible via cruise ports in our area.  We left from Fort Lauderdale, but Tampa, Port Canaveral, Miami and other places offer cruises to many destinations.  If you haven’t tried one, check it out.

We’ve been to Nassau several times and wouldn’t normally think of it as our favorite port.  But this time we had a wonderful visit and got to see (and taste) a lot of new things.  Highly recommended!  I’ve embedded links to most of the places above.  Please click on them  for more info.  And you can see more Bahamas images in this folder on Flickr.

More Computational Photography

As an Electrical Engineer and a long time photographer, I’ve been interested in computational photography for a while.  You can read some of my  earlier posts on the subject at this link. Here’s Wikipedia’s definition:

…”digital image capture and processing techniques that use digital computation instead of optical processes.”

I’d change this slightly from”instead of” to “instead of or in addition to”, but that’s a small quibble.

Moore’s law keeps driving the computing capabilities in phones and cameras ever higher and it’s fascinating to see what companies do with the extra potential.

Towalga River below High FallsTowalga River below High Falls, Georgia. Composite – iPhone default live view and Long Exposure, merged in Photoshop

I made the image above on our recent trip using an iPhone 8+ and Apple’s “Live Photo” mode. After I made the photo, I edited it on the phone and enabled the “Long Exposure” effect. The Long Exposure effect of blurring the moving water is computed from ~3 seconds worth of frames that Live Photo captures.  This is Apple’s web page explaining the feature.  Here’s what it looked like before I changed the mode – it’s not nearly as photogenic:

Towalga River below High FallsDefault iPhone live view

Until iOS 11 added this feature, I wasn’t too interested in Live Photos.  Now, I’m watching for places to use it. You can get a better image with your high-end camera and traditional optical techniques, but this is easier and a lot of fun to play with.

Here are some hints:

  • Pick a suitable subject:  moving water, traffic on a road, blurring people in a crowd, etc.
  • Motion blur with a traditional optical approach requires a slow shutter speed – either low light or using filters.  Since computational methods works by processing multiple frames, you can use it in bright light without filters.
  • Apple says it works on their newer phones (6+ and later).  You’ll need to have iOS 11 (or later) installed.
  • The Long Exposure effect has to align Individual frames and then crop where there’s no overlap so you’ll lose pixels around the edges.  Ideally, use a tripod – but that sort of defeats the idea of pulling your phone out of your pocket, doesn’t it?  Just hold the phone as steady as you can to minimize cropping.
  • Make several exposures and pick the best one later.
  • Long Exposure resolution seems to be lower than default iPhone photos.  This isn’t a huge problem for the moving parts of the frame – they’re supposed to be blurry.  For the static portions, you can load both versions into layers in Photoshop and use masking to paint in higher resolution where you want it.  I did this for the first photo above.
  • You can set a Long Exposure photo as your wallpaper.  You’ll see the static Long Exposure version until you press on it from the lock screen.  Then it changes to show the three-second animation – cool!

I hope Apple enhances this in future updates.  It’d be good to have some control over the blur effect.  3 seconds is nice, but some subjects will look better with less (or more?).

iOS 11 includes other updated computation photo capabilities (e.g. portrait lighting) – but that’s a subject for another day.

Photography’s changing fast – it’s a wonderful time to be a photographer, isn’t it?  In today’s digital world, many advances are likely to be computational and not optical.  Keep up – don’t be left behind!

Veterans Day 2017

The Armistice ending World War 1 was signed on the 11th hour of the 11th day of the 11th month of 1918.  In the United States, President Woodrow Wilson proclaimed Armistice Day for November 11, 1919 to commemorate.  President Dwight Eisenhower signed legislation in 1953 renaming it Veterans Day and extending the holiday to honor all veterans.  It’s a day to thank veterans for their dedication – a day to honor all those that place their country above themselves.

“It’s about how we treat our veterans every single day of the year. It’s about making sure they have the care they need and the benefits that they’ve earned when they come home. It’s about serving all of you as well as you’ve served the United States of America. Freedom is never free.”  President Barack Obama

Vietnam War DisplayVietnam War Display, Smithsonian American History Museum

As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them.” President John F. Kennedy

“I don’t have to tell you how fragile this precious gift of freedom is. Every time we hear, watch or read the news, we are reminded that liberty is a rare commodity in this world.” … “We owe this freedom of choice and action to those men and women in uniform who have served this nation and its interests in time of need. In particular, we are forever indebted to those who have given their lives that we might be free.” President Ronald Regan

Thanks to all active duty service members and veterans.  And thanks for stopping by and reading my blog.  Now – you go out and thank a veteran too!

Indian Springs State Park, Georgia

Indian Springs is about six hours by car from Central Florida.  It’s east of I-75 between Macon and Atlanta and well worth the drive.  Lynn discovered they have cabins and suggested that we go up for a few days to see if any leaves are changing.  They definitely are!

ColorColor

I think peak color will be in a week or so. We get very little fall color in Florida – so it was a treat to see.

The cabins are nice – some of the best we’ve stayed in.  They must have been refurbished not long ago.  They have two bedrooms, one bathroom, a kitchen, a living room, a screened porch, and are fully furnished.  And the location  on a gorgeous lake was wonderful. This was the view just a few steps from the back porch:

There were other things to see in the park too.  This creek runs along the road by the entrance.

And we spotted this cemetery from the 1800s along the road to the cabins.

We saw a few deer and although I didn’t put much effort in, several kinds of birds.  We had some fun watching (and listening) to Canada Geese on the lake.  I managed to make this video one morning around sunrise.  The flock took off just as the sun started to hit the lake.

There are several other places to see in the area.  High Falls State Park is just to the east and Piedmont National Wildlife Refuge is to the west.  We’ve explored several state parks in Florida, but after this experience, we’re going to expand our target zone!  And Indian Springs is definitely on our “go back” list.

Photography’s not important. Yes it is!

Sorry about the glitch last Thursday – I didn’t mean for this post to go out then.  Hitting the wrong button in WordPress is embarrassing, but at least my email subscribers got to see an example of how my posts usually begin – as just a few words jotted down to expand on later.  Here’s the rest of it.

BloomingBlooming

In the grand scheme of life, photography  isn’t required.  We managed for most of our history without photos.  And even today, with cameras in every cell phone, many people never make a photo.  So is photography important?

Barred Owl PairBarred Owl Pair

The world is awash in geo-political problems.  World leaders with nuclear weapons call each other names and threaten annihilation.  Scientists say global warming is going to drown our coast lines.  Storms and earthquakes cause massive destruction and loss of life.  Watching the evening news is overwhelming and sometimes even depressing.  In this world, how important is an activity like photography?

Bald EagleBald Eagle

Images and video play an increasing role in documenting problems and news in our society.  Ubiquitous cell phone cameras give us a look into life as it happens, views that were less likely to be seen in the past.  Is that a good thing?  In general I think so, even though what we now see all the time is often uncomfortable.

Barn OwlBarn Owl

Photography is also a tool. It lets us explore and comprehend things we can’t view with our own eyes.  Just look at the incredible images that the Cassini probe has sent back from Saturn.  This is extremely important data leading to a better understanding of our universe.  Vital?  Maybe not, but it is important.

What about photos like the ones in this post?  Are they important?  Maybe not to you, but to me they are.  When I’m out photographing I can forget all about many worrisome things and concentrate on an activity I enjoy.  If I’m lucky I become completely absorbed in the process – “in the zone”.  Worries drop away – at least for a time.  And sharing the results may not be crucial, but I do think it’s worthwhile.  Allowing others to see what I can and they can’t is an activity worth doing.  The photos don’t have to worthy of the Louvre. But’s it’s nice to get one every once in a while that goes up on my wall.

These photos were all made at the Audubon Birds of Prey Center in Maitland Florida.  They take in injured raptors, treat them, and (if they’re well enough) return them back to the wild.  They’re able to release just over 40% of their raptor patients.  Some birds (like the ones pictured here are too severely injured, so they become permanent residents that we can photograph when we visit.

The images don’t have a lot to do with the ideas in the post.  But they’re good examples.  The act of making them got me out of the house to meet a friend.  We enjoyed seeing the birds, and our donations will help the Audubon society to continue to help injured raptors.

Thanks for stopping by and reading my blog.  Now – go make some photos – it’s important!

Counting our Blessings

Hurricane news has dominated this week, and it’s been hard to think much about photo ops.  Irma’s path through the Caribbean and Florida left huge swaths of devastation –  destroying lives, homes, livelihoods, and infrastructure.  The Keys are especially hard hit.  I’m sure you’ve seen reports so I won’t repeat them here.

I will let you know that our family is counting our blessings.  We have some roof damage, and we’re dealing with a few other repairs (and damage from the Equifax leaks too!) but all of our utilities are working.  There are many places close-by that are still without power.  It seems like most businesses in Central Florida are gradually re-stocking and re-opening – so unlike some, we’re able to get groceries and gas.

Bright Double Rainbow after Hurricane IrmaBright Double Rainbow after Hurricane Irma – Our daughter MK (and her cat Milo) stayed with us during the storm and when the Orange County Florida curfew ended on Monday night, we drove her back to her place. On the way home, we saw this incredibly bright double rainbow and stopped in the empty McDonald’s parking lot to make a photo with my iPhone. The skies were clearing and hopefully it’s a sign that everyone affected by Hurricanes Harvey and Irma are on the way back to recovery.

There’s still a lot of flooding in Florida and more is forecast.  In our area, Lake Jesup is over its banks and may go higher.  I’m guessing that  the flood waters will drown the late September / early October sunflower fields along the north side of the lake this year, similar to what happened in 2008 after Tropical Storm Fay.  Even if they do bloom, getting out to them will be a soggy mess at best.  We’ll probably have to wait for next year.  Hopefully then we’ll be wondering about photo ops again instead of storms.

To everyone suffering from the effects of the recent hurricanes, our hearts go out to you.  For the rest of us that haven’t suffered as much – take time to remember how lucky we are and what’s really important.

Thanks for stopping by and reading my blog.  I’ll try to get back to the normal blog articles  soon.

Hurricane Irma may pass directly over Bahia Honda State Park

This morning, we’re waiting to see what Hurricane Irma is going to do and it looks like it might pass directly over Bahia Honda State Park as a Cat 4 or Cat 5 storm.  It’s hard to imagine the damage that could result.

Lynn and I returned from the Florida Keys a week ago.   We spent a couple of days in Key West and then were lucky enough to stay in one of the 6 cabins at Bahia Honda State Park for 3 more days.  They’re built on stilts but even so are only about 10 -15 feet above the ocean.  And we felt them swaying at times while we were there – even in good weather.

The cabins are on the right side of the overseas highway as you head down to the keys.  They’re furnished with everything you need for a great Florida vacation.  And the location on a beautiful lagoon is wonderful.  These next three photos were all made on the patio, just a few steps from the cabin door:

Loggerhead TurtleLoggerhead Sea Turtle – The ranger told us that turtles, dolphin, and tarpon like the lagoon because it’s so quiet and protected.  We’d see one or more of Loggerheads from the cabin porch almost every time we stepped out to look.  We also saw Tarpon rolling on the surface a few times and maybe a dolphin or two.

Sunset FishingSunset Fishing – You can fish in the lagoon by the cabins, but other water activity isn’t allowed.  We often saw campers fishing there.

The view from the cabinAnother view from the cabin porch. The skies at Bahia Honda are some of the darkest in Florida. Lynn and I got up at about 1:30am on our first night. The moon had set and we had a stunning view of this part of the Milky Way, right from the patio. And the bugs weren’t biting too much!

The Looe Key National Marine Sanctuary is about 8 miles southwest of Bahia Honda and snorkeling trips leave for the reef twice a day.  It was a relaxing swim – the water temperature was in the high 80’s, which can cause storms to strengthen.

Sergeant majors and othersLooe Key Sergeant majors and others –  The visibility wasn’t very good the day were were there, but the number of fish we saw was still impressive.

There are also 72 campsites in the Park.  Many of them are in awesome locations too.

Between the bridgesBetween the bridges – This is at sunset, between the old abandoned bridge on the left and the new one on the right.  You can see some of the lovely Bahia Honda campsites on the left side of the frame.

Lynn and I thought of this visit to Bahia Honda as a “scouting trip”.   Based on what we saw, we definitely want to go back.

To everyone in Irma’s path and to everyone impacted by Harvey:  We’re thinking of you.

Thanks for stopping by and reading my blog.  Now – stay safe in the storm!

Moon Shadows – August 21, 2017

Did any of you notice the solar eclipse in the US last week?  Here at Central Florida Photo Ops HQ we certainly did!  And even though the full moon covered “only” ~85% of the sun, it was still an awe-inspiring show.

Our experience in Winter Springs started with heavy rain and thick cloud cover, but the sky quickly cleared and from then on we had an amazing view.  I put together this time-lapse movie with ten photos I made at about ten minutes intervals :

To set up my camera, I first focused manually on a very distant tree and taped down the focus ring.  Then I spent some time figuring out exposure so detail on the sun’s surface would show.  The sun is really bright!  I put two stacked neutral density filters in front of my lens to cut the light by about 11 stops.  I ended up shooting in manual exposure mode at ISO 64, f/16, and 1/1000 sec at 800mm equivalent focal length.   For insurance, I also bracketed around that base exposure.  Luckily there were a few sunspots to see:

Sunspots on the surface

We had two other roving photographers on assignment to help document the eclipse.  Kevin McKinney was in Orlando south of us.  He noticed the sun shining through a tree and made the photo below.  Small openings between the leaves were acting as pinhole lenses and focusing multiple images of the crescent sun on the ground.  I’m glad he noticed this, I didn’t think to look:

Howard Thomas (our other roving photographer) braved scarce hotels and huge traffic jams to report from Santee, South Carolina along the path of totality.  He made these next three photos:

Eclipses are fun to think about.  They’re such a huge coincidence!  The Moon is 400 times smaller than the Sun, and the Sun is 400 times farther way.  So they’re the same apparent size in the sky – that can’t be very common in the universe.  We don’t see one very often because the Moon’s orbit tilts with respect to Earth’s orbit around the sun.  And since the moon is slowly moving away from the earth, the geometry will be ruined after another billion years.

You can click on any of these photos to look at larger versions.  I hope you were able to see this stunning event and get some photos of your own.  If not, the next one in the US is in 2024.

Thanks for stopping by and reading my blog.  Now – go be amazed by rare natural phenomenon.  And make some photos!

Any Micro 4/3 Camera Regrets?

The short answer is “Nope, not really”.  For the longer answer, read on…

Sometimes I’ll take a camera by Bear Creek Nature Trail in our neighborhood (the middle of Tuscawilla, along the north side of Winter Springs Boulevard).  On this particular day back in January of 2017, sunlight was filtering down through the trees and hitting the water at a bend in the creek.  The light refracting  through ripples in the surface created interesting patterns and colors I thought were worth a shutter click.

Bear Creek ripples 1aBear Creek Ripples 1a  (28mm eq. focal length, f/8, 0.5 seconds, ISO 64)

This was a month or so after I started using the Olympus E-M1 Mark II camera.  I’d sold my Nikon D-800 and lenses so I could afford to upgrade my Olympus kit and I was still getting used to the new gear.  I’d had the D-800 for over four years and it’d worked extremely well for me.  It was the very best camera I’d ever used so getting rid of it was a big step and I was still second guessing my decision.

Why did I sell the Nikon gear and move exclusively to Olympus?  And how is it working out?  Glad you asked!

It seems that discovering micro four thirds cameras is a big thing on the web, lately.  Here are a few links with a lot of information you can investigate:

I won’t repeat these discussions.  Everyone will have their own opinion and reasoning for the camera equipment they use. I’ll just summarize by saying that for me, no regrets.  The smaller and more modern design has many advantages with few real issues.  For what I shoot, I haven’t seen much downside.

I can carry much more camera capability with far less weight.  And the new gear does things the older Nikon equipment doesn’t.  Really, the only thing that concerns me even a bit is star / astro photography with the smaller sensor.  I haven’t had much of a chance to test this yet and hopefully ease my concerns, but even if the Olympus isn’t as good at this type of photography, I’m not very worried.  I don’t do it all that often and if I need to, I can always rent / borrow a different camera with a larger sensor or use something like the iOptron SkyTrackerTM  to make really long exposures. Your mileage may vary of course, and you should investigate thoroughly before you make such a significant change.

If you have questions, feel free to ask in the comments.  I’ll be more than glad to try to answer.  And you can click on the image below to go to Flickr and browse through an album of the images I’ve  made with the new camera:
