About The Unsharp Mask Filter…
Photoshop’s Unsharp Mask Filter is the most common sharpening tool used by photographers during post production. Although its name sounds like an oxymoron when the goal is to actually sharpen an image, it definitely does exactly that — sharpen. Well, sort of. Applying the Unsharp Mask Filter actually results in the illusion of sharpening, where the human eye is tricked.
Too Much Of A Good Thing
Most photographers new to Photoshop have a tendency to do a bit of overkill when first learning the program and experimenting with its filters. I know I was certainly guilty of that in my early days with the program and my entry into the world of digital post production.
Use of the Unsharp Mask Filter is certainly one area where lack of experience — or limited understanding of the filter’s slider controls (Amount, Radius, and Threshold) — visibly shows its hand.
The sharpening error that most often appears in the details of certain images is called “halos.” However, halos are not always due to inexperience and overkill. There are times when halos are just a byproduct of a perfectly legitimate use of the Unsharp Mask Filter.
Regardless of whether due to inexperience or a legitimate byproduct, halos are ugly and distracting.
What Exactly Are Halos?
Halos are those white (sometimes dark) lines that appear between highly contrasted areas. View your images on-screen at 100% and really check the edges of your subject matter. While halos might not be that visible in a small size print, they will be exponentially more visible in larger print sizes. Definitely not a good thing!
Let’s Take A Look
Here’s an example where I deliberately oversharpened my image. At first glance the overkill might not look too obvious. Don’t be fooled. Halos are indeed there.
Now Let’s Take A CLOSER Look
When we zoom in to take a closer look, you can clearly see that oversharpening produced very noticeable halos along the edges of the lighthouse (as well as along the railing, rocks, and horizon in the full image above). Can you imagine just how obvious and distracting that would be in a nicely framed large size print? Ugh! That’s why it’s important to always check the details in your images on-screen at 100%.
Now if I noticed the halos during my initial post production of this image, I could immediately correct the flaw by making some adjustments to the Unsharp Mask Filter control sliders. But what if I only discovered the halos after the fact?
Don’t panic. It’s never too late to correct the problem.
To start, find your current “final” image file and open it in Photoshop.
How to Fix Halos In Your Images
As with most things in Photoshop, there are several different methods on how to do something. This includes fixing halos. Most techniques for fixing halos have one thing in common — selecting the Darken (or sometimes Lighten) layer blend mode.
Here are a few different video tutorials to show you how to remove halos in greater detail. Try the different techniques and decide which method works best for you and your image.
Unsharp Mask Tutorial
Let’s go back to basics for a moment. For those of you new to Photoshop or those of you simply in need of a quick refresher on the Unsharp Mask control sliders, Adobe’s Principal Digital Imaging Evangelist, Julieanne Kost, has a great video tutorial on the very subject.
In A Nutshell
Before you have prints made from your files, do yourself a favor — check for halos first. You’ll be glad you did.

Winter In New England
It’s been an interesting winter here in New England thus far. We’ve certainly seen an extreme range of temperatures, not to mention some “wicked” ice storms and a recent Nor’easter blizzard.
During this time of year, many of my fellow photographer friends love to grab their camera equipment and venture out to face the elements head on. I wish I could say that I was one of those adventurous photographers, but alas my thin blood and extremely low tolerance to the cold has me instead living vicariously through them.
While I’ve added many new “To Buy” items to my “Winter Photography Clothing Gear List,” in reality I spend most cold winter days indoors staying warm and exploring my creative side through a variety of post-production filters and techniques. I will touch on a few of my favorite post-production filters here today.
I Know I’m Not Alone…
I suspect I’m not the only photographer who tends to avoid the possibility of frozen fingers — and exposing my equipment to ice, snow, and sub-zero temps. So for those of you with simpatico minds — and I know there are more than just a few of us — this article might give you a few new ideas on how to reinvent an existing image, or perhaps take your post-production process in a new direction altogether.
So let’s get to some of those favorite post-production filters of mine…
Photoshop comes equipped with several built-in filters. Poster Edges is one of them. You can easily access it from the Filter pull-down menu at the top of your screen. (Filter > Artistic > Poster Edges). The filter’s image adjustment sliders then let you alter such things as Edge Thickness, Edge Intensity, and Posterization to your preference for that image.
For this image, I took a macro shot of a coneflower. I then added a texture layer for a fine art effect. For a final step, I applied the Poster Edges filter to give the image a contemporary look.
Oil Paint Filter
Another favorite Photoshop filter of mine is the Oil Paint Filter. This filter comes packaged with Photoshop CS6 and Photoshop CC. The Oil Paint effect also shipped as a free Pixel Bender Gallery plugin for Photoshop CS5.
Note: Variations of an oil paint effect are also available as third-party PS plugins from software makers such as Topaz Labs.
“Less Is More”
To what degree one applies the Oil Paint Filter to an image very much depends on personal taste. I’m a big proponent of “less is more” when it comes to using this filter. Being conservative with the adjustment sliders gives the image a far more realistic oil painting look in my opinion. However, there are no “rules” to creativity. Surrealism certainly has its place, so by all means feel free to experiment and turn reality into something as abstract as your imagination envisions.
Flaming Pear Flood Filter
I love the Flood Filter by Flaming Pear. You can use it to turn the ordinary into the extraordinary, or to give added dimension to a visual story.
In this shot, I used it to add a dramatic — and somewhat surreal — effect to one of my HDR Battleship Cove images taken in Fall River, Massachusetts. The adjustment sliders for this filter give you great latitude for “flood placement” and water detail manipulation.
Topaz Star Effects
Who doesn’t like adding a little pizzazz to images that already feature an illuminated light? I certainly thought this sunrise shot of Maine’s Portland Head Light deserved such a treatment — and Topaz Star Effects made it possible. Again, I believe in the “less is more” approach. The “blue hour” of morning was beautiful in and of itself. Adding a subtle star effect to the beacon seemed like a nature fit to accentuate the beauty of the moment.
So there you have it. Several examples of the different type of post-production filters you can play with on a cold winter’s day.
As you know, it’s only mid January. We still have a couple of months of this New England winter to go. Since we can’t change it, I say let’s embrace the opportunities it offers.
For some that means bundling up and dazzling the rest of us with spectacular winter images. For the rest of us, it means having fun — and staying warm — at our computers while we enjoy some post-production experimentation.
However you choose to survive this winter’s cold weather, enjoy!

Fun to Explore in Every Season!
Cape Ann’s Halibut Point State Park on Gott Avenue in Rockport, Massachusetts, attracts a wide variety of people year round. Regardless of the season, there’s always fun to be had. Everyone from hikers to birders to coastline explorers and photographers love this idyllic location that borders the Atlantic Ocean.
Historic Granite Quarry
Once home to a large granite-quarrying operation around the turn of the 20th century, the park is now cooperatively managed by The Trustees of Reservations and the Massachusetts Department of Environmental Management.
Views of the former Babson Farm quarry are diverse and include scenic vistas, granite reflections, changing foliage, and some magical sunsets.
Hiking Trails, Dramatic Surf and More!
Featuring 2.5 miles of trails and a rocky coastline overlooking some dramatic surf, the park is a wonderful place to explore. Hikers enjoy climbing the rocky ledges and traversing the trails that make their way through the woods, around the quarry, and along the edge of the ocean.
A Birder’s Paradise
Bird watchers get a diverse eyeful year round — including loons, grebes and a variety of ducks. Tidal pools delight visitors with harbor snails, hermit crabs, and sea stars. I love to visit every season, as migration patterns bring different feathered friends to the park throughout the year.
View from the Visitor Center
The park’s Visitor Center is housed in a renovated World War II fire-control tower near the edge of the Babson Farm Quarry. This 60-foot tall structure offers a panoramic view that includes Crane Beach in Ipswich, Massachusetts, Mount Agamenticus in Maine, and the Isles of Shoals off the coast of New Hampshire.
Halibut Point State Park is open year round from sunrise to sunset. A small parking fee is charged year round. Admission is FREE for Trustees members (proof of membership required), and also for pedestrians and bicyclists.
On weekends from Memorial Day through Columbus day, tours of the quarry are offered by staff and volunteers.
A self-guided walking tour brochure is also available for download by clicking here.

Note: Dogs must be kept on a leash at all times.
Worth The Trip!
So if you’re heading to Cape Ann — or looking for a great new place to explore — make sure to check out Halibut Point State Park. It’s worth the trip any time of the year!

Beautiful & Bountiful Cape Ann
Cape Ann — the “other” Cape — is located approximately 30 miles northeast of Boston, Massachusetts. Surrounded by the Atlantic Ocean on three sides and separated from the mainland by the Annisquam River, Cape Ann’s picturesque coastline is home to six very different lighthouses. With each lighthouse being within a relatively short driving distance to the next, Cape Ann makes for a perfect day trip with lots of visual bang for your gas tank buck!
Even though Cape Ann consists primarily of four towns — Gloucester, Rockport, Essex, and Manchester By-The-Sea — the locations of the six lighthouses are evenly split between Gloucester and Rockport. A 19-mile route along Rt. 127 to the north, Rt. 127A to the south, and then over to Gloucester Harbor’s Stacy Boulevard covers the entire lighthouse viewing territory.
But as they say, a picture’s worth… well, you know. So, let’s get to it!
Annisquam Lighthouse stands on the east side of the Annisquam River at its northern end known as Wigwam Point. The present day 41-foot cylindrical brick structure was built in 1897 on the same foundation that supported two previous towers — both wooden — back in 1801 and 1851 respectively. The original keeper’s house, enlarged and altered over the years, still stands today.
While the actual grounds of Annisquam Lighthouse are now closed to the public, the lighthouse can be seen from Wingaersheek Beach and also nearby from Lighthouse Beach which is part of the Squam Rock Land Trust. Some boat tours also pass Annisquam Lighthouse for a close-up view from the sea. Sunset is a beautiful time to be there…
Straitsmouth Island Lighthouse
Straitsmouth Island Lighthouse can clearly be seen from the tip of Bearskin Neck in the tourist friendly town of Rockport. Originally constructed as a 19-foot lighthouse in 1835 to help direct vessels to the harbor at Pigeon Cove, it was later replaced in 1896 by a 37-foot brick tower and moved 500 feet to its present location.
This relatively small lighthouse is maintained by the U.S. Coast Guard. The island itself, however, is now owned by the Massachusetts Audubon Society as a bird and wildlife sanctuary.
Thacher Island’s Twin Lighthouses
Thacher Island’s Twin Lighthouses are the only surviving multiple lighthouses on the coasts of the United States. The two 124-foot granite towers that stand today — the North Tower and South Tower — were built in 1861. The original lighthouses, constructed and lit in 1771, were unique historically, as they were the last built under British rule and the first in the U.S. to mark a dangerous area, rather than a harbor entrance.
During the summer Thacher Island is open to visitors. A shuttle boat operates out of Rockport Harbor. I’ve been fortunate to have visited the island several times, including at sunrise to capture some magnificent blue hour color, and also to climb the North Tower for a great view of the island.
When on Cape Ann, I love to view and photograph Thacher Island and its twin lights from Loblolly Cove. Every time I go there, I hike around to a different vantage point. On this day, sunrise was masked by storm clouds. All was not lost, however, as I loved the moodiness it created, as well as the flashing lights of the towers, the fog on the water, and the bright spotlight in the distance of a solitary lobster boat.
Sometimes each tower features its own magic. Such was the case this day as the full moon majestically rose beside the island’s South Tower. I knew it was going to rise there as I had checked The Photographer’s Ephemeris that morning. Once again, my location was Loblolly Cove, but this time I had hiked over to the far side of the cove so that I could shoot directly across to the island.
Eastern Point Lighthouse
Eastern Point Lighthouse was originally built in 1832 to mark the entrance to Gloucester Harbor. The stone 30-foot structure was later replaced in 1848 with a new 34-foot lighthouse. A two-story duplex house, oil house, garage and fog signal building were all later added between 1879 – 1951.
Today the lighthouse station serves as active housing for the U.S. Coast Guard. While the grounds to the lighthouse are closed to the public, you can walk the 2,250-foot granite Dogbar breakwater for an excellent view.
Note: Eastern Point Lighthouse is easily accessible from downtown Gloucester by following Eastern Point Avenue to the very end where there is a small parking lot for lighthouse visitors.
Ten Pound Island Lighthouse
Ten Pound Island Lighthouse is located within Gloucester Harbor. The island itself — named for the number of sheep pens (pounds) that it could hold — boasts housing America’s first Coast Guard Station. Originally constructed in 1821, the lighthouse marks the island and assists in navigating Gloucester’s inner harbor.
Famous artist Winslow Homer boarded with the lighthouse keeper in the summer of 1880. During that time, Homer painted approximately 50 scenes of Gloucester Harbor, several of which included Ten Pound Island Lighthouse.
The lighthouse can easily be viewed from many locations along Gloucester’s waterfront, especially from Stacy Boulevard. Views can also be had from tour boats that pass through the harbor.
Great Day Trip!
Well, there you have it. Six great lighthouses all in a small square mile radius. Pretty sweet driving route too. It doesn’t get much better than that. As you can see, Cape Ann makes for a great day trip for anyone who is a lighthouse lover — or for anyone who wants to become one quickly.
So, the next time you’re looking for a fun day trip, come visit Cape Ann’s six lighthouses!
