This presentation briefly goes through the steps of how I processed a high dynamic range image of a cloudscape during stormy season in Hong Kong.
High dynamic range images or HDR, is the process of combining multiple low dynamic range captures into a single image, when a single capture does not afford the necessary range for what is intended.
Three captures were made for the making of the final image. All three images share the same ISO, the same aperture value, and the same focal length. They differ in shutter speed, and the result is shown here, with one normal exposure (0EV), one 3 stops down (-3EV) and one 3 stops up (+3EV).
The image on the left was exposed for the overall intent: the clouds and the reflection on the sea. The image in center was exposed for the highlights, which provides some tonal details in the sunlight in this case. And the image on the right is exposed for the shadow areas, where the buildings on the horizon are now correctly exposed, and you can see the patterns on the water surface.
After importing my RAW captures into Lightroom, I have exported them to merge to HDR via Photoshop. I used to use Photomatix for this but lately I have been using Photoshop because it was easier for my workflow.
The important bits to note here is that you should be focusing on extracting details from the captures, and not trying to create the final image.

Then I do the same for the water area. Note that at this point this image is very similar to by 0EV capture—no surprises there. This was what I saw when I photographed this photo. I do HDR not for effect, but just so that I can have some details on the shadow area.
At this point you see that really there is not much color to this scene. In fact, they stand to distract the overall image, so I removed it. Here since I have been working in Lab mode I just quickly removed the color channels or just removed the color saturation. If I work with images filled with color I usually would use the channel mixer in RGB mode or use the black and white tweaking modules inside Lightroom. But as you can see there is not much color in this image to start with so I can simply just remove the color saturation.
After importing back into Lightroom, I tweak things further as I feel that I can still get some more details in the shadow area. If I were inside Photoshop I would do a image-wide shadows/highlights tweak but since Lightroom version 4 there is this new Clarity parameter which works very well in manipulating local contrast so I used it.
And that’s it. But remember, every single image is different. This is not a recipes. There are no rules. Now go have some fun!
Cheers.

Workflow: I created the larger object in the background with Blender. I wanted to use Mudbox to retopologize and since MB requires a "clean" mesh, I exported the object into Maya. Performed "cleanup" and smoothing in Maya, then to Mudbox for re-topology. Finally imported back into Blender and rendered the scene using Luxrender.
This is my current workflow, the last step may vary naturally. I don't always use the same filters, but Adjust and Detail from Topaz Labs quite often used
The only trick here is that I've stopped using my laptop at shoots, and rely solely on the 64gb iPad 2 for downloading and reviewing. When I get home, I dump all of the photos to my 11" Macbook Air, catalog and rate them in Adobe Lightroom, then store them on one of two remote Drobo volumes, via a wirelessly shared Mac Mini. The mini is also running Backblaze, which backs up the contents of the Drobo.
This workflow will be augmented (hopefully for the better) as soon as PhotoSmith comes out.

Earlier this year one of the participants on a discord server I frequent put up a framework python script that allows the export of node based materials in Blender to .XML text based materials usable in Studio. I've expanded on it to include more node types...enough so that it's almost usable.
One of the things that drives me crazy about Studio is the endless iteration required to develop new materials. Being able to use Blender to shortcut this process has been extremely helpful.
In this case, I've been trying to figure out an accurate solution for an acrylic material.
This is a shot list that I make of the images that I'd like to take when I do my walkthrough with the REALTOR® client (or on my own, if no client meets me at the property).
This idea came from the Interior Photo Workshop that I took in January 2009 in suburban Chicago from Photographers Scott Hargis and Thomas Grubba
Suggested and recommended workflow to
- 'ingest' your NEF raw files from your Nikon camera onto your computer / into VNX2
- view your NEF images
- classify them
- process / edit / adjust them.
N.B. Access help by pressing the F1 function key.
The quality and clarity of the information available in the help panel is extraordinary first rate, it includes many definitions of terms used in digital photography.
The output from this (VNX2 suggested) process will be high quality images that should lead to an improvement in your photography, plus your mind's eye.

Medieval castle situated in the heart of Cannes Old Town, Le Suquet
The Castre Museum is located on the Suquet hill, dominating the city of Cannes. From the top of the medieval tower visitors can see the bay and the Lerins islands
Inside the castle and the nearby chapel is a brilliant collection of paintings, art and archaeological artefacts. The Castre Museum is home to a wide collection of antiquities, particularly from the Mediterranean and the Middle East.
The 11th-century Saint Anne Chapel houses a remarkable collection of musical instruments from Asia, Africa, America and Oceania. A few rooms dedicated to 19th-century Provencal paintings of Riviera landscapes open out onto the courtyard and a square tower displaying spectacular views.
It is surrounded by a beautiful Mediterranean garden with pine trees [seecannes.com]

In our tree nursery, which we have established in 2015, ten workers grow more than 4 million seedlings with the highest quality standards.
Until 2029 there will be 100 Million trees grown, planted and cared for. If 10.000 projects copy us, the trillion trees will bind a quarter of the human made CO2.
Overview of Codex Alimentarius
by Rima Laibow, M.D.
At the request of the United Nations (UN) in 1962, the World Health Organization (WHO) and Food and
Agriculture Organization (FAO) took on the joint role of running and administering the Codex
Alimentarius Commission (CAC) to establish standards and remove barriers to trade for all food and
food products. Having declared that nutrients are toxins from which we must be protected, the CAC
has been busy establishing enforceable international guidelines for upper limits of nutritional
supplement dosing. Codex has goals that affect every person in the UN’s 170+ member nations,
including the United States. As a tool for furthering these goals, member nations are urged to adopt
Codex standards and guidelines as domestic policy. The United States has already committed itself to
doing so despite U. S. law which prohibits this compliance.
The World Trade Organization (WTO) has adopted Codex as a standard for the adjudication of foodrelated
international trade disputes and has the authority to enforce Codex standards through
implementation of harsh economic sanctions on non-Codexcompliant member nations. Pre-existing
international treaty laws dictate that WTO rulings will override the domestic laws already in place in
its member nations and, in fact, the WHO has successfully taken both states and the U. S. government
to court in the U. S. to force changes in our domestic laws eleven times. This means our nation’s hard
won laws that give you access to over-the-counter, natural health supplements will become
meaningless. Codex’s original mandate to remove barriers to trade and assure a clean food supply has,
under the influence of private, economically-driven multinational pharmaceutical, agricultural and
chemical corporations, self-expanded far beyond its original mandate. The result is a body of highly
dangerous and restrictive policies that threaten to become domestic law in the U. S. and, as such, are
a threat to your health and freedom.
The FDA has stated explicitly that its goal is complete "harmonization" with Codex and, in order to
bring that about, international regulations i.e., Codex will be given preference over domestic ones!
(Federal Register, 10/ 11 /95)
If Codex gets its way, as it already has in the EU, we can expect that, ultimately, only 18 or so dietary
supplements will be available over-the-counter in doses which are, by design, far too small to have any
discernible impact on any human being since codex classifies nutrients as toxins. High potency
nutrients will not be available either with or without physician’s prescription since these molecules
and compounds will be forbidden under any circumstances. The big surprise? Once in the hands of
pharmaceutical companies, consumer supplement costs are expected to more than quadruple. This
has, in fact, been the experience in Europe where this process is already underway and micro-dose
nutrient prices have increased 10 to 100 fold or more (e.g., in Norway a bottle of zinc lozenges which
previously cost $2 now costs $54; in France 12 Vitamin C tabs of just10 mg cost $117; while 10 Vitamin
E caps of only 10 IU each cost $110).
Australia and the European Union (EU) are in the process of enacting harmonized Codex policies that
restrict consumer access to nutritional supplements. America is next. Though Americans value
personal freedom, the fact Codex meets infrequently (and almost always offshore) and is bogged
down in highly technical language that is difficult to understand has resulted in many Americans
being unaware of this threat. The nearly total media blackout on Codex and its activities helps to
keep the U. S. uninformed and therefore, pliant.
While there have been rare serious adverse reactions to nutritional supplements during the past
decades, (usually when taken far in excess of the recommended dosing), numerous severe and even
fatal reactions to drugs (usually when taken at the recommended dosing) occur every day and are the
fourth leading cause of death in hospitalized clients in the United States when properly
used. When improperly used, they are, in fact, far and away the leading cause of death in
the United States. Even so, drug deaths are very likely underreported. Drugs are
inherently dangerous; nutrients are not. This fact makes it clear why the drug culture
2
needs to eliminate all access to natural health options, including nutritional supplements,
in order to expand and intensify its influence and thus its profitability. Healthy people
take fewer drugs and thus are poor customers.
The global pharmaceutical powers -that-be have already purchased a large piece of the
lucrative global nutritional supplement pie but the considerable size of this pie keeps the
hugely profitable pharmaceutical profit -share-pie from reaching its maximum size so the
competing nutrient pie must be destroyed. Though unable to patent a natural substance,
pharmaceutical corporations can hold patents on synthetic versions of vitamins and
minerals that, unfortunately for the consumer, often do not act like their natural vitamin
counterparts in the body and often act in unpredic table and harmful ways. If Codexcompliant
Europe is any guide, the permitted micro-doses of permitted nutrients will be
only synthetic ones.
In addition to regulatory and/or administrative takeover and destruction of the dietary
supplement market and consumer access, Codex also mandates irradiation of food;
mandatory use of antibiotics, hormones and growth stimulants in all animals raised for
food, is expected to legalize the unlabeled inclusion of Genetically Modified Organisms (GMOs) (whose
safety has never been established while their serious dangers have) into our seed and food supplies and
will increase the allowable maximum tolerated levels of pesticides, herbicides, veterinary drugs and
other dangerous industrial toxins in food, likely driving up degenerative illnesses, including cancer,
diabetes, cardiovascular disease, macular degeneration, MS, etc. All of these policies are made under
the guise of free and equal access to trade for all nations and protection of the public.
Some people have “Codex Anesthesia,” a state of overwhelming, numb confusion that occurs just
before people lose their health freedom. Many otherwise well-informed people from the manufacturing
and retailing sectors of natural healthcare believe that the Dietary Supplement Health and Education
Act (DSHEA), passed in 1994 to protect Americans’ access to natural healthcare substances, will still be
in place to protect them. This is not the case: Fundamental health freedoms afforded the American
public by DSHEA, which classifies supplements as food which, as such, can have no upper limit set on
their use, are now under well orchestrated legislative and/or administrative attack. Health nuts and
junk food devotees alike are not immune from this legislative attack on health freedom.

* Chrome, iTerm2, Emacs.app always running in fullscreen mode.
* Auto-hidden dock.
* Two desktops, book-ending the fullscreen apps (each with their own wallpapers)
* Using whatever tweaks I can find to remove animations, or at least decrease animation delays.
This workflow has been surprisingly good, so far.
