Enhanced details?

Have you heard about Adobe’s recent update to Lightroom?  It has a new feature called “Enhance Details”.  Adobe says it:

“approaches demosaicing in a new way to better resolve fine details and fix issues like false colors and zippering. Enhance Details uses machine learning—an extensively trained convolutional neural network (CNN)—to provide state-of-the-art quality for the images that really matter.”

You can read an explanation of what they’ve done on their blog at this link:  https://theblog.adobe.com/enhance-details/.  It sounds like a another fascinating advance in computational photography.  It’s also a great example of why you should shoot in Raw mode and save your original files – so you can take advantage of future software updates.  Of course I had to try this out!

Flower & bugWildflower and bug – processed in Lightroom with Enhanced Details (click for a larger view)

I chose this flower growing in Central Winds Park, near Lake Jesup as my subject.  By the way, this is the same spot and subject as this 2015 blog post.  There’s a lot of detail in the flower and insect and I was curious about how it would look using the new processing.

I ran Enhance Details on the Raw file.  At first, I couldn’t really see any improvement.  So I opened the original and enhanced images in layers in Photoshop.  I set the layer mode to Difference and then used a levels adjustment to highlight changes.

Using this method at 300% magnification to guide me to where the changes were, I could then see them clearly.  The enhanced image was indeed more detailed than the original.  But (for this example anyway) they’re extremely subtle!  Too subtle to show up in a blog resolution image without a difference map.

I did a little more research on-line and found this blog post:  https://elialocardi.com/adobe-lightroom-camera-raw-enhance-details-review/.  It’s got several samples where the differences are more obvious.  Well worth a read.

Here are my thoughts:

  • Adobe claims a 30% increase in image quality.  I’m not sure how they derived this number, but from the examples I’ve seen the results are much more subtle than that.
  • It works better on some subject than others, e.g. night photos of cities with lights, or images with artifacts.  Improvements are much harder to see on other subjects such as my flower.
  • I didn’t see (and haven’t heard of) anyplace where it made an image worse.
  • You pay a penalty in workflow, time, and disk storage when using this.  It shouldn’t be your default processing.
  • Consider it for portfolio images, or photos that you’re printing in a large format. Don’t bother with it for images shared to the web or ones that you’re printing small.  Keep your Raw files and you can always go back later and run them through.
  • If you use Fuji cameras, try it on their X-Trans Raw files.
  • We’ll hear more soon as the photo community explores this and we see results.
  • In the future this or something like it will probably become the default demosaicing approach.  Adobe should be commended and I hope they keep developing it

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

Viera Wetlands 2-6-19

Here are some photos from a trip to Viera Wetlands last week.  There’s a lot to see there!

Ash-throated Flycatcher (?) Eastern Phoebe. Ash-throated Flycatcher(?) I didn’t recognize this bird when I made the photo.  and I’m still not totally sure what it is.  A Great crested Flycatcher was seen at Viera Wetlands in January, but this one seems too small for that. An Ash-throated Flycatcher was seen there in previous years. Many thanks to Wally Jones for the ID help!

So I had a very nice visit to a wonderful place – if you’ve never been, now is a good time to go!

First, check the web page!

I missed out last week on a trip with Kevin K. and Kevin M. to the Circle B Bar Reserve due to some dental work (ouch!).  So I was eager to photograph something this week.  My schedule was finally clear on Friday, and when I woke up early, I decided to go walk around Orlando Wetlands Park – one of my favorite spots in this area.

Whoops.  I suspected something was wrong when I got out of the car and heard engines running.   I walked out toward Lake Searcy in the dark and when I saw construction gear and  no water in the corner cell, I turned around.   Fortunately I’d gotten up way too early, so I still had time to change my “plans” and almost make sunrise over on the coast.

After that, I headed to Merritt Island National Wildlife Refuge.  There are a lot of winter migrants here now.  The birds must’ve known beforehand about this week’s Polar Vortex.  In addition to our year round species, I saw American Avocets, Lesser Scaups, Northern Shovelers, Hooded Mergansers, and fast warblers I couldn’t ID.  I also stopped and talked to some folks on Black Point Wildlife Drive who were trying to find a Cinnamon Teal that’s been seen there.  I heard later they found it again on Saturday.

So my photo adventure started out badly, but turned out well.  Those engines I heard were pumps.  I checked the OWP web page when I got home – they’re “demucking” Cell 14.  And there’s also construction going on in Cell 16.  I’ll go back in a while when the ruckus dies down.  Don’t be like me – check the web page before you go.  Even if you’ve been there many times!

iPhone Event Photography

MK won two extremely good tickets in a drawing at work for a recent Orlando Magic game and invited me to go with her (Thanks MK!).  I was excited and looked up the camera policy for the Amway Center.  The relevant sentence was:

“Cameras with detachable lenses longer than six (6) inches when extended are prohibited from all Amway Center sporting events.”

I put my Olympus 12 – 100 lens on my E-M1 2 camera, stuck an extra battery in my pocket, and was ready to make some super photos.  When we arrived I was stopped by the first security guard I saw at the start of the entrance line and told that no interchangeable lens cameras were allowed.  I didn’t think it was worth arguing, so I begrudgingly took my camera back to the car.  After going through the line to get in, we asked about the policy and were told that yes, interchangeable lens cameras are allowed!

Amway – you need to make sure your security people understand your policies!  Anyhow, I was tired of walking back and forth to the car and decided to just make photos with my phone.

Nikola Vucevic grabs a reboundNikola Vucevic grabs a rebound. Orlando Magic vs. Brooklyn Nets. The Magic led for most of the game, but lost by two in the final seconds.

Which ended up working well, since the seats were in the first row!  I used the 2x lens and shot in RAW mode using burst to capture the peak action.

I think a main disadvantage of phones vs. dedicated cameras is the lens selection, especially at the telephoto end.  Phones right now usually have two or three lenses at most.  Standalone cameras have a virtually unlimited lens selection available.  At events, you need to be close to the action or you need to use a long lens.

Last week, Lynn and I went to a concert at the Plaza.  Their camera policies are more restrictive (and  vague).  They can also change, depending on the performer, so I left my camera gear at home.   Our seats this time were about eight rows back, which was close enough to get a few iPhone photos of one of my favorite guitar players.

I would’ve liked to get closer.  And the resolution isn’t as good as I’d want for prints on the wall.  But phones can work surprisingly well – if your seats are good enough.

I have more Orlando Magic photos in this album on Flickr.  And a few more Jorma Kaukonen photos in this one.

Sometimes my photo plans don’t work out.  But I make photos anyway.  It’s what I do.  Thanks for stopping by and reading my blog.  Now – go make some photos!

Flagler Beach Whale Quest

MK and I decided to drive over to Flagler Beach last Sunday.   Several whales have been seen recently – one the week before from the pier. We knew the chance we’d spot one was very small, but it’s a pretty place for sunrise and the restaurant on the pier serves a decent breakfast!

We set off at “o-dark-thirty” and arrived before dawn.  I spent some time making photos on the beach and when it was light enough, we went up on the pier to scout.

Under the pierUnder the pier

North Atlantic Right Whales are among the most endangered whales in the world.  There are only about 450 left.  In addition to deaths from ship strikes and fishing gear entanglement, their birth rate seems to be declining.  They migrate south from New England to the warm waters off Florida to mate and give birth.  Unfortunately, there were no new calves spotted last year during the whole 2017 – 2018 season.

So it was pretty exciting when the first calf was spotted this year:  https://www.news-journalonline.com/news/20181228/right-whale-watchers-rejoice-as-calf-spotted-off-jacksonville-coast!

Humpback Whales are also seen off our coast.  They’re usually further out than the Right Whales, which seem to stick closer to shore.

We ate breakfast and then drove to a couple more spots on the beach.  We knew before we left that day that our chances of seeing whales were slim.  But we all know our chances are zero if we never look.  And although we came up empty, it sure was a nice morning and worth the drive.

Here’s more info on Florida whales:

In a Garden

Lynn added some Birds of Paradise plants to our front and back gardens a few years ago.  They’ve done well – we often have multiple flowers open at the same time.

I featured a portion of one blossom in this post from the summer of 2017.  It turns out that they bloom in the winter too!  Here are some more photos, this time  of the whole flower.

Bird of ParadiseBird of Paradise – side view, on black

The Bird of Paradise (Strelitzia reginae) is also known at the Crane Flower because it resembles the head and beak of a colorful exotic bird.

They’re indigenous to South Africa and enjoy full sun and warm temperatures like we have here in Central Florida.

In their natural habitat, they’re pollinated by Sunbirds, not insects.  The weight of the bird standing on the flower releases pollen onto the bird’s chest or feet, which is deposited on the next flower it visits.

They make lovely additions to our Florida garden, and lovely photography subjects too.  I made these images in the early morning before the light got harsh.  Lynn held black or white material behind them for me.  I like the one on black the best.  How about you?

Is Merritt Island National Wildlife Refuge Shutdown?

Kevin M. asked if I wanted to go photographing on Saturday and we decided to go over to Merritt Island National Wildlife Refuge.  I hadn’t been in a while and I wanted to see how it’s doing during the Government shutdown.  We also invited Kevin K. to go along.

Sunrise by the causewaySunrise by the causeway

We stopped at the Titusville Marina for a few sunrise snaps.  A cold front was passing through and it was still overcast and a little dreary.  But there was a small break in the clouds right at daybreak.

As far as the shutdown goes, this is what the MINWR website says:

“Where public access to refuge lands does not require the presence of a federal employee or contractor, activities on refuge lands will be allowed to continue on the same terms as before the appropriations lapse.”

So facilities at MINWR are closed and locked, but the trails we tried were open (Gator Creek road and Black Point).  We didn’t see any rangers, but the wildlife is still showing up.

Note:  Jim Boland reports that Cape Canaveral National Seashore (Playalinda) and Biolab Road are closed.

Some of what we saw:  a Bald Eagle, Ospreys, a Northern Harrier, Belted Kingfishers, a Reddish Egret, Coots, Common Gallinules, Northern Shovelers, Blue-Wing Teals, Hooded Mergansers, Pie Billed Grebes, White Pelicans, Roseate Spoonbills, Great and Snowy Egrets, Great and Little Blue Herons, Tri-colored Herons, White Ibis, and Alligators.

The birds were fairly abundant, but I struggled to get good images.  The light was  dim under the clouds and the birds were a little too far away.  We even came up on a feeding frenzy.  But it was in a small pond behind some thick mangroves that were just about impossible to photograph through.  Here’s my best shot of that – this Ibis was diving back in to get another snack:

The sun broke through one other time before we left:

All in all, a pretty nice photo expedition.  So don’t use the government shutdown as an excuse. – you can still go out and enjoy our natural resources.

Long(er) cruise exposures

I thought you might be interested in a photo technique that I used on our recent cruise. Here’s an example image:

Journey's End

Journey’s End. (eq. FOV: 26mm, f/4.5, .8 sec @ ISO 1250)

In low light situations, I wanted the ship sharp in the foreground, and nearby water showing motion blur. I also wanted features on the horizon to be sharp (with no motion blur).

You can see the settings I used in the captions. The secret is to use a wide-angle lens, and keep your shutter speed fast enough so that the ship’s motion doesn’t result in blurred features on the horizon, but long enough so that the close by water shows some motion blur. For this image, a little less than a second worked out. Here’s another example (that was in last week’s blog too):

Approaching the Cayman Islands

Approaching the Cayman Islands. (eq. FOV: 26mm, f/4, 2 sec @ ISO 200)

Here are the steps to try this yourself:

  • Go on a cruise!
  • Choose an aperture that gives you the depth of field you want (e.g. sharp focus from foreground to horizon).  My Olympus 12-100 f/4 lens is sharp and has sufficient depth of field used wide open.
  • Choose an ISO value that results in the shutter speed you want (between 1/2 and 2 seconds).  With my micro 4/3 cameras, I’m conservative with ISO, but I’ll use up to 3200 if pressed – even for landscape shots.
  • Use your camera’s built-in image stabilization (or mount your camera on a tripod) to stabilize it on the ship.  Since my setup has the Olympus dual-IS capability, I didn’t use a tripod.  Instead, I braced myself against the ship and  hand-held these.
  • Make several exposures and check for sharpness. Since the ship is moving relative to the horizon, this setup is different from a normal dry-land photo.  To keep the horizon sharp, you’ll have to either time the ship’s motion and expose when it’s minimized (difficult), or make multiple frames and pick ones where the horizon features are sharp (easier).  I was able to get sharp images with exposures as long as 2 seconds, but I made multiple frames for insurance.

Here’s one more photo.  The light was brighter in this one, so I couldn’t get much blur in the water:

Dusk at seaDusk at sea. (eq. FOV: 24mm, f/4, 1/40sec @ ISO 200)

So that’s it.  A fun technique that will give you some nice “cruisey” images.  If you try this, let me know how it works for you.

Caribbean Voyage

Lynn and I returned a week ago from a Caribbean cruise on the Holland America MS Oosterdam where we met up with her brother Art and his wife Michele.  Since we’ve been back we’ve had Mike, Sara, Calvin, and Avon in town for the holidays (and MaryKate – yay family!!!).  Anyway, I don’t have a lot of spare time for writing this week, so  I think you’ll just have to make do with some photos and captions from our cruise.  I hope you enjoy them!

Inviting!Inviting!  – This scene is from the beach on Half Moon Cay (Holland America’s private island).  Lynn and I both enjoyed the sun, some swimming and conversations with Art and Michelle.

Make it a double...Make it a double.  – There were other things to do on the island too!

Clouds over CubaClouds over Cuba – We haven’t ever been to Cuba and this is as close as we got on this cruise.  This photo is from six miles east of the Punta Maisi Lighthouse.  I wish it had been clearer and closer!

Clouds in the valleyClouds in the valley – I spotted this low cloud bank as we arrived in Montego Bay Jamaica and rushed to make several images.

Approachig the Cayman IslandsApproaching the Cayman Islands – We were scheduled to stop in Grand Cayman, but the seas were too rough for the tenders to operate.  The captain ended up skipping that port call and moving on early to the next one.

Cozumel at nightCozumel at night. – I had hoped to get many more images in Cozumel, but the photography tour we’d signed up for was canceled (due to lack of interest!).   I like this photo of the city after dark.

It was an enjoyable, relaxing trip.  You can see a few more photos in this album on Flikr.  And you can read other cruising blog posts at this link.

We’re having a wonderful time with family visits for the holidays – I hope you are too!.

Thanks for stopping by my blog.  Remember to make some family portraits while you have a chance!  Merry Christmas and Happy Holidays to all!
