Hollywood Cinema – DJI Is Coming After You

October 20, 2021October 20, 2021Kevin

To stabilize a camera for video filming, we have seen several types of stabilization:
(1) Large Steadycam body-mounted on a vest. (This was invented around 1975.)
(2) Hand-held stabilizers that rely upon counter-balance weight
(3) Computerized gimbal operated with two hands and support cinema cameras such as RED, Sony, Canon, etc
(4) Computerized gimbal that can be held with just one hand and support smaller cameras
(5) Very small devices including camera and gimbal with a total weight of 16 oz or less.
(6) In-camera mechanical techniques for stabilzation, either lens-shift or sensor shift
(7) Digital image stabilization

Computerized gimbals have been a game changer, invented around 2012. The larger 2-handed category has been dominated by Freefly MoVI series and DJI Ronin series of products. These systems do not include camera, video monitoring, or follow-focus.

Today, DJI introduced another game-changer – the new DJI Ronin 4D. This is no longer just a stabilization device, rather it is a complete system, including the camera. Surely many film-makers will not readily abandon their trusted cameras and lenses, but at first glance, Ronin 4D does seem to be a game-changer.

Cost: The complete system is less than $10K. Compare this to assembling a comparable system from separate components. Either a RED Komodo or Canon C300 Mark III will set you back more than $8K and that does not even include any lens.
The built-in ND filters is a pretty big deal; can potentially eliminate need for a bulky matte box.
The LIDAR system looks truly amazing.

The Ronin 4D Cinematic Imaging System includes:

Cinema camera: 6K @ 120 FPS, or 8K @ 75 fps, or
10-bit Pro-Res
Six built-in ND filters
Computerized 6-Axis stabilization gimbal
7″ touchscreen video monitor, detachable and wireless
LIDAR focusing system
long-range wireless 1080 video transmit (with encryption and frequency hopping)
2.5-hour battery

Schooner at Gloucester Harbor

September 6, 2021September 6, 2021Kevin

In addition to visiting Gloucester this weekend, I also ported all my photography and tools to a new computer. As I imported new images from a camera drone, I took the new computer on a test drive to verify that my tools were all in good order.

This scene had both very bright highlights and very dark shadows; I doubted that a single exposure could contain both the highlights and shadows. As you likely know, such situations are known as high dynamic range (HDR). I captured a bracket of three exposures. In retrospect, it was a wise choice. The middle exposure was spot on, however the foreground was nearly black and some background highlights were blown out – white boats and white buildings. The darker exposure provided correction for the blown-out highlights. The lightest exposure was used to replace the black foreground water with dark-blue water.

Initially, I processed each of the three in Lightroom and then combined them together using Photoshop. From Lightroom, open the three images using “Edit In” -> “Open As Layers In Photoshop”. Once opened in Photoshop, select all three layers and choose “Edit” -> “Auto-Align layers”. Here, there are six Projection options; I chose “Reposition” because the three images were identical composition that varied only by exposure.

A selection of the highlights was applied as a layer mask on the darkest layer, such that only the highlights are used from that layer. A selection of the foreground dark water was applied as a layer mask to the brightest layer such that the foreground is lightened. The resulting image is shown here on the right.

From there, I applied three image filters by Alien Skin. First was Bokeh, to blur the image – except for the schooner. Then I used two different variations of Snap-Art. All this was done through Photoshop. Upon saving all of this (TIFF file), I was back in Lightroom. Judicious use of brightness, clarity, and color saturation enhanced the simulated brush strokes. The end result is shown here on the left.

Wild Katahdin Landscape

March 15, 2021March 15, 2021Kevin

Mount Katahdin, northern terminus of the Applachian Trail

I’ve been thinking of turning this image into a wall poster and have finally done that. The scene is remarkable in particular because a solitary person appears quite small and provides the viewer a sense of scale. This mountain is unlike any other east of the Mississippi River.

I created this photograph during a solo visit to Katahdin. After spending the night at Chimney Pond, I arose early and ascended a very steep trail up to the top of the ridge. As a matter of lucky coincidence, this unidentified lone hiker happened to be about twenty minutes ahead of me.

Here’s what the medium-size poster looks like on my Redbubble store (https://www.redbubble.com/people/kevinheaven/shop).

2020 Cherry Blossom Watch – Boston Update

April 21, 2020November 5, 2022Kevin

April 19 – Boston
At the Public Garden, the flowering plum trees are solidly at peak bloom. Although some cherry trees are beginning to drop their flower petals, color will soon be reborn once the crabapples begin to bloom.

The jackpot of cherry trees is located nearby at the Charles River Esplanade. Here, multiple varieties of cherry trees are near peak bloom and should be giving a great display all this week. Of course, the Kwanzan Cherry trees (near the Hatch Memorial Shell) have not yet begun to bloom.

Charles River Esplanade, Boston Massachusetts

April 21 – Portsmouth, New Hampshire

Cherry trees near City Hall have not yet begun to bloom. Just across the street at Langdon Park, the prettiest tree in Portsmouth is just beginning to display the first few flowers. Downtown on State Street, flowing plum trees are displaying good color.

Re-processing Photos for T-shirts & Coffee Mugs

April 16, 2020April 16, 2020Kevin

Recently I have been working through my photography catalog for the purposes of overhauling my website. At the same time, I’ve been recognizing that some images can be repurposed for graphic t-shirts and coffee mugs. My latest design is shown here; the left version is intended to be printed on light backgrounds and the right version is intended to be printed on dark backgrounds.

My products at Redbubble: https://www.redbubble.com/people/kevinheaven

For this particular work, I used Adobe Photoshop and multiple plugins by Topaz Labs. To adjust the color palette and to enhance the details, I commonly use Topaz Adjust and Topaz Detail.

Here’s the original digital photo from ten years ago. This was probably the first time I had ever taken a digital SLR on a backpacking trip. Because I had not yet learned the features of this camera, I neglected one of the most remarkable features of the Canon 5D mark II … the first DSLR camera capable of 1080p high-def video. To this day, I regret that I did not capture any video in this remote unique landscape.

If you look closely (click on the image to see a larger view) toward the top right of the image, you will see blue blazes painted on the rocks; these blazes mark the hiking trail … a very narrow trail with a potentially nasty drop-off.

2020 Cherry Blossom Watch : Boston MA

April 5, 2020Kevin

All photos in this post were created this morning in Boston.

Considering that the peak bloom in Washington D.C. is at least a week early this year, I am a bit surprised that the timing of cherry blossoms in Boston is looking to be far more normal.

Washington D.C.

“Peak bloom” of the cherry blossoms in Washington D.C. generally pertains to the Yoshino cherry trees.

(According to the National Park Service) This year, peak bloom occurred about March 20, compared to last year when peak bloom occurred April 1. The March air temperatures this year were about seven degrees (f) warmer than last year.

Several years ago, I was in D.C. for the cherry blossoms when spring temperatures arrived earlier than normal. Fortunately for me, I caught the peak bloom just a day or two before a wind storm knocked most of the blossoms off of the Yoshino trees on March 25.

Branch Brook Park, Newark NJ

A 360-acre park, Branch Brook hosts 5000 cherry trees, the highest density of cherry trees anywhere in North America. With numerous varieties of cherry trees, they do not all bloom at the same time and peak season can last two to three weeks.

As I visited Branch Brook in 2019, the trees were spectacular around April 11.

In 2020, in the interest of social distancing for COVID-19, the park was formally closed to visitors. I can find no information regarding the timing of the cherry blossoms.

Boston MA

A bit akin to Branch Brook Park, Boston has a variety of different trees such that “peak bloom” in Boston is not a singular period of three to five days. Furthermore, Boston’s flowering trees include species other than cherry trees. The Back Bay area is known for Magnolias that bloom at the beginning of April, a dozen varieties of cherries, followed by Kwanzan Cherry that bloom near the end of the month, and then joined by Flowering Dogwood.

In 2019, cherry blossoms along the Charles River Esplanade were stunning around April 22.

Today in 2020, along with the blooming of Magnolias, both Haigan and Weeping Haigan cherry are just now blooming. While I did see two other cherry trees blooming, most cherry species have not yet begun to bloom in Boston.

One Year After The Fire

October 23, 2019October 23, 2019Kevin

Mid-October 2018, I photographed Wakefield Massachusetts using an aerial drone. As the autumn colors were not well developed yet, I returned a week later to make the same photo again. That’s the first photo here, October 23, 2018.

Some renovation work was in progress that day. You can see scaffolding against the steeple and one of the tall windows is laying on the grass.

In the evening later that day, a lightning storm passed through the area and this presumably sparked the fire that destroyed the First Baptist Church. The next day, I again put the drone in the air to photograph the aftermath of the fire.

Today is the one-year anniversary of that fire, so I returned to again make the same photograph, but without the church.

Outdoor Photography – chasing mother nature

June 28, 2019July 28, 2022Kevin

Rumney Marsh photographed with an aerial drone (sUAS)

I first visited Rumney Marsh in the month of May. Although I discovered some great photo compositions, the marsh was mostly brown. Presuming that the grasses would fully transform the landscape into a greener palate, I vaguely planned to return some weeks later. Shown here below is my first image from the May visit:

This year, spring in New England has featured more rain than normal. Dry days are a bit like currency – have to spend them judiciously. Five or six weeks later I returned to the marsh on a dry day and found the green grasses covered the land, as expected. Unexpectedly, coastal clouds were lingering and the water reflected white sky (not blue sky).

While that is a nice image, … I had imagined the water reflecting a blue sky. So, I returned later that same day after the clouds cleared away. That final image is shown at the top of this article.

In all three instances, the image required post-processing for HDR, particularly because the buildings on the horizon were too bright. So each of these three instances is a combination of multiple exposures, simply to control the dynamic range of light.

Photo Opportunity – Blooming of the Cherry Trees

March 25, 2019Kevin

Evening at the tidal basin, Washington D.C.

Flowers blooming on Cherry trees is a harbinger of spring because Cherry trees bloom first, before other flowering trees. While these blooms are a much anticipated spectacle, predicting when the cherry trees will bloom … is difficult business.

From Macon Georgia to Boston Massachusetts, you can visit well-known groves of cherry trees. The trees bloomed in Georgia last week. Unfortunately, I missed it because of car trouble.

The very first blooms appeared in Macon GA around March 10. The very first blooms appeared in Washington D.C. just a few days ago.

The general blooming of Cherry trees in Washington D.C. has not happened yet, but should begin by end of this week. Midweek temperatures this week are still cool with overnight temperatures close to freezing. The current weather forecast tells that the temperature will warm this Thursday. So, blooms should be popping this coming weekend.

At our nation’s capitol, people do actively report the progress of the cherry tree buds. Here’s an update today:
cherry-blossoms-now-at-stage-4-with-peak-bloom-fast-approaching

The best-known location around D.C. is the tidal basin, shown in the photo above. As you can see in this late-day photo, it can draw a dense crowd. You will not find crowds like this early in the morning.

Public Art (on utility boxes)

August 22, 2018Kevin

Stopping at a coffee shop downtown, I put a quarter in the parking meter. When I returned, 20 minutes remained on the meter, so I took a short walk. That’s when I happily discovered art on a utility box … and another … and another.

While I prefer a camera with interchangeable lenses, at times like this I am happy to have a mobile phone with a camera. My phone-camera is not a great camera, but as the saying goes … the best camera is the one you have with you.

I must also note that Android / Google Photos includes some photo post-processing functions that I rarely use but did use here. The leftmost image was badly overexposed. The problem was very well solved by applying “auto”.

(No, I’m not giving up my big interchangable-lens cameras.)
