Just thought I'd share this little tip with everyone on how to check to see if you need a sensor cleaning. I noticed a couple of spots in the top right corner of some of my photos and thought it was the lens at first. After switching lenses and seeing that the spots were still there I thought I'd investigate sensor cleaning procedures.
I found this site:
www.cleaningdigitalcameras.com/inspecting.html
that explains how to take a test shot (seen above) to see how much dust is on your camera sensor. As expected I have a couple of dark spots in the top right of mine ... and a bunch of others I hadn't noticed in my photos.
It's been just over a year since I got my camera so I'm going to send it in for a professional cleaning which will hopefully get rid of 99.99% of the dust.
Hope this tip proves helpful.

Nikon D810 Fine Art Photos John Muir Country-- Kings Canyon & Sequoia! Dr. Elliot McGucken Fine Art Photography during a Breaking Thunderstorm with Majestic and Interesting Skies!
I always love getting away and photographing John Muir Country--Yosemite, Kings Canyon & Sequoia in California I also shot it all with the Sony A7r as well as the Nikon D810 and the wonderful Nikon 14-24mm f/2.8G ED AF-S Nikkor Wide Angle Zoom Lens as well as the new Tamron AFA012N700 15-30 mm f/2.8-Di VC Wide-Angle Lens for Nikon F (FX) Cameras and the Nikon 28-300mm f/3.5-5.6G ED VR AF-S Nikkor Zoom Lens !
I hope that you enjoy browsing through my photos and comparing and contrasting the Nikon D810, Sony A7r, Sony A7rII, and the various lenses!
Long story short, you can't go wrong!
The Sony A7r and the Nikon D810 have the same sensor! While the D810 saves the RAW in 14bit lossless compressed (or uncompressed0, the A7r performs a bit of lossy compression, which I have never noticed, but which some say they have!
At any rate, I am super excited for the Nikon's next camera as well as for the recently released Sony A7rII Mirrorless Digital Camera which I now own! Some highlights include a 42 MP Full-Frame Exmor R BSI CMOS Sensor, a
BIONZ X Image Processor,
Internal UHD 4K Video & S-Log2 Gamma, and a
5-Axis SteadyShot INSIDE Stabilization system! You can see some of my fine art photos from the amazing camera in my photostream, with many more to come!
And I have a feeling that Nikon will be releasing something epic soon--a 50mp+ camera with awesome dynamic range!
An important thing to remember is that even though pixel sizes keep getting smaller and smaller, the technology is advancing, so the smaller pixels are more efficient at collecting light. For instance, the Sony A7RII is back-illuminated which allows more photons to hit the sensor. Semiconductor technology is always advancing, so the brilliant engineers are always improving the signal/noise ratio. Far higher pixel counts, as well as better dynamic ranger, are thus not only possible, but the future!
Yes I have a Ph.D. in physics! I worked on phototranistors and photodiodes as well as an artificial retina for the blind. :)

Compare these D810 shots with the photos taken with the Sony A7r and new Sony 16-35mm Vario-Tessar T FE F4 ZA OSS E-Mount Lens!
After looking through my work,what do you think about Nikon vs. Sony? Do you prefer the Nikon D810 and Nikkor / Tamron / Sigma lenses /glass, or the Sony A7r and Sony Sonnar Carl Zeiss e-mount glass/lenses? I love them both! And I am so excited about the Sony A7rII !

I get asked a lot of questions (I love questions--ask away!), and one of the more common ones is "What kind of camera shoul I buy?" Begin with anything, and then, when it falls short of the beauty you are trying to capture, invest in a new one! The important thing is to think of it as buying not something for yourself, but a gift for the world, who will witness all the magnificent photos you shoot with it! Then, the next most important thing to do is to shoot, shoot, shoot, shoot! For each and every epic shot on an awesome camera helps justify its cost! I shoot with the awesome Nikon D810, Sony A7R, and now the Sony A7RII! And in the long run, the cost of the camera is a very small entity, when conpared to the cost of life and time. So buy a great camera, and then give the gift of epic photography to the world! View your artistic mission into photography as an epic odyssey of heroic poetry! Take it from Homer in Homer's Odyssey: "Tell me, O muse, of that ingenious hero who travelled far and wide after he had sacked the famous town of Troy. Many cities did he visit, and many were the nations with whose manners and customs he was acquainted; moreover he suffered much by sea while trying to save his own life and bring his men safely home; but do what he might he could not save his men, for they perished through their own sheer folly in eating the cattle of the Sun-god Hyperion; so the god prevented them from ever reaching home. Tell me, too, about all these things, O daughter of Jove, from whatsoever source you may know them. " --Samuel Butler Translation of Homer's Odyssey
All the best on your Epic Hero's Odyssey from Johnny Ranger McCoy!
For those who've wondered at my probably annoyingly often references to the damage to my camera, here it is in all its glory.
The only reason I'm sharing this is because of the amazing flare my 10-20mm produced here.
Do you clean your own sensor? I bought the MARUMI Low Pass Filter Cleaning kit which I will attempt to use next time I have dust on the sensor. Getting tired of having the camera shop do it.

060109-N-3019M-010.PEARL HARBOR, Hawaii (January 9, 2006).The Sea Based X-Band Radar (SBX) navigates the channel as it enters Pearl Harbor, Hawaii aboard the heavy lift vessel MV Blue Marlin after completing a 15,000-mile journey from Corpus Christi, Texas. SBX is a combination of the world's largest phased-array X-band radar carried aboard a mobile, ocean-going semi-submersible oil platform. It will provide the nation with highly advanced ballistic missile detection and will be able to discriminate a hostile warhead from decoys and countermeasures. SBX will undergo minor modifications, post-transit maintenance and routine inspections in Pearl Harbor before completing its voyage to its homeport of Adak, Alaska in the Aleutian Islands.

SNL Dennis Roach with a Comparative Vacuum Monitoring (CVM) Sensor showing galleries etched-sensors underside. He lead team that's evaluating some-sensors for Structural Health Monitoring (SHM) aircraft and safety equipment.
The Comparative Vacuum Monitoring sensor is a self-adhesive rubber patch, ranging from dime-to credit-card-sized. The rubber's underside is laser-etched with rows of tiny interconnected channels or galleries to which an air pressure is applied. Any propagating crack in the materials under the sensor breaches the galleries and the resulting change in pressure in monitored. The sensors are made by Structure Monitoring Systems, Inc. (SMS) of Australia, are in expensive, reliable, durable, and easy to apply. They provide equal or better sensitivity than is achievable with conventional inspection methods. Besides, aircraft, SHM techniques could monitor the structural well-being of spacecraft, weapons, rail cars, bridges, oil recovery equipment, buildings, armored vehicles, ships, wind turbines, nuclear power plants, and fuel tanks in hydrogen vehicles.

New safety installation at the industrial railway of Stadler when crossing the main road. This system operates independently of the normal train protection. If a shunting loco stands above this sensor, the system can be activated by a smartphone app. Staad, Altenrhein, Switzerland, March 7, 2015.
This is the Oxygen Sensor, also called Lambda Sensor or O2 Sensor. It's screwed into the exhaust crossover to sample tailpipe emissions, and send a signal back to the ECU. For this project it's not necessary to remove the sensor, which is good since they are often corroded in place.
There are 4 wires inside the black wiring sheath;
2 white for the sensor heater
1 grey for sensor ground
1 black, the signal wire - the important one for us
Major milestone: The first of 21 "science rafts" for the 3.2-gigapixel Legacy Survey of Space and Time (LSST) camera from Brookhaven National Lab. The rafts are arrays of nine imaging sensors, or CCDs, each with 4K-by-4K pixels. The LSST camera will be the largest digital camera ever built for astronomy. It will provide researchers with the widest, deepest and fastest views of the night sky for unprecedented studies of the Milky Way, the solar system, dark matter, dark energy, and much more. SLAC is assembling and testing the camera from parts built by a large collaboration of labs and universities.
LSST is funded by the National Science Foundation (NSF), the Department of Energy (DOE) Office of Science, and private funding raised by the LSST Corporation. For more information, visit: lsst.slac.stanford.edu/.

Quick splash in the dishwasher a wee massage with a towel and put it all back together and get lovely crisp shots ... Thanks Google !
In the final version we poked the reed switch out more so it could be closer to the magnet on the wheel.

A finales de enero, Francia declaraba “patrimonio sensorial” protegido por la ley a los sonidos y olores del campo, entre ellos el tañer de las campanas. Rosalía hubiera celebrado la noticia.
LAS CAMPANAS
Yo las amo, yo las oigo
cual oigo el rumor del viento,
el murmurar de la fuente
o el balido del cordero.
Como los pájaros, ellas,
tan pronto asoma en los cielos
el primer rayo del alba,
le saludan con sus ecos.
Y en sus notas, que van repitiéndose
por los llanos y los cerros,
hay algo de candoroso,
de apacible y de halagüeño.
Si por siempre enmudecieran,
¡qué tristeza en el aire y el cielo!,
¡qué silencio en las iglesias!,
¡qué extrañeza entre los muertos!
(Poemario: "En las orillas del Sar")

All art is but imitation of nature.-- Seneca (Letters from a Stoic - Letter LXV: On the First Cause)
The universe itself is God and the universal outpouring of its soul. --Chrysippus (Quoted by Cicero in De Natura Deorum)
Season of mists and mellow fruitfulness
Close bosom-friend of the maturing sun
Conspiring with him how to load and bless
With fruit the vines that round the thatch-eves run;
To bend with apples the moss'd cottage-trees,
And fill all fruit with ripeness to the core;
To swell the gourd, and plump the hazel shells
With a sweet kernel; to set budding more,
And still more, later flowers for the bees,
Until they think warm days will never cease,
For Summer has o'er-brimm'd their clammy cells. --To Autumn. by John Keats

Hi everyone...I was "smart" enough to listen to my friend who mentioned that it would be a good idea to use compressed air to clean the sensor...This is the result...took a snap of a white sheet of paper and noticed this crap was on there!!!
Obviously I went absolutely crazy!!! The stuff wouldn't come off...wouldn't evaporate and I was scared if I left it there too long it would burn a hole through the sensor filter and damage the sensor...so I did the most unspeakable act....
...
...
brace yourself...
...
...
yes...
...
...
I TOUCHED THE SENSOR!!!
I took out the softest thing I had at the time - my Spudz lens Cloth (I was out at the time) and wrapped it round the end of a pens ink tube and gently cleared it off...Its still there around the sides but it doesn't show up in pics anymore which is good...thank goodness it didn't scratch it!
No place near here cleans sensors so I just got a proper sensor cleaning kit which should *hopefully* arrive tomorrow morning...will clean it properly then...
Can you feel my pain?!
(Picture is of entire sensor uncropped...thats how bad it was)

In many fatigue assessments characterising the applied service loading is the most difficult and critical step.
Fatigue Integrity Management has over fifty years experience in the design and installation of systems to allow in-service load or stress spectra to be established through acquisition and analysis of load, strain and displacement records.
CrackFirstTM sensors provide an alternative long term system for fatigue usage monitoring on steel structures. Attached adjacent to a fatigue critical detail, the sensor responds to cyclic loading by changing its output in proportion to the cumulative fatigue damage for a typical fillet welded joint. The sensors allow an estimation of remaining life of the structure and safe usage-based inspection intervals.
A wide range of structures and components has been assessed for TWI Members including earth moving equipment, road trucks and tankers, bridges and pressure vessels.
TWI operates a quality assurance scheme certified to ISO 9001:2000 by LRQA and BS EN ISO 14001:2004
and is an IiP certified company.
