I know I risked my camera's sensor burning out because of the direct intense sunlight, but I just couldn't pass this shot up. :O
.
Shot with Laowa Optics 9 mm F2.8 which translates to about 14 mm equivalent on the Canon M6 APS-C sensor. Very compact, very solid metal construction, seems sharp. A nice fast ultrawide travel companion for the M-series camera.
The view from the Monorail platform is my favorite view in all of Disneyland, which explains why I always head here to test some new gear or methods...Friday evening I did exactly that, with my new Rokinon 14mm f2.8 lens.
My vision of Disneyland (as seen through my camera) has always been a wide one, where I was most happy with Canon's 10-22mm lens on my cropped-sensor 7D. Most of my pals were already shooting full-frame cameras which left me a feeling a little "inadequate" when viewing similar scenes from both cameras. When I (finaly!) switched to a full-frame camera a couple of months ago, I bought Canon's 5D Mk III with a 24-105 f4 "L" lens which left me a little cramped in my compositions at Disneyland. Additionally, I found myself having to re-learn tricks that I had mastered with the 7D and was floundering a bit, feeling like I had a new toy that was broken.
Time being a premium this year, as I am a father of a high school senior planning college, etc., I have not been able to get into the Park for some quality shooting and tinkering. This past Friday found me at Disneyland able to play and experiment and I finally am feeling at home again.
Since I am most comfortable shooting wide, and hoping to find my sweetspot again, I went looking for a wide lens to use until I win the Lottery...with a suggestion from my friend Corey Dorsey, and after borrowing his lens a couplke of times, I commited to buying the Rokinon 14mm f 2.8 and, so far, I am completely happy with this little gem of a lens. With manual focus only, and manual aperture controls, it is already comfortable to me because I manually focus anyway when shooting landscapes...Also it is extremely affordable. Happily, with f 2.8. I was able to stop all the motion in this dynamic scene to acceptable levels.
This lens has been criticized for some unusual "mustache" distortion, but there are correction profiles available for Lightroom that fixed things right up...
All in all I am very happy with this lens!
Salamander elite pilots use the Nautilus SP-350 as a deep sea exploration submarine ship. Its technology is based on the close observation of cephalopods in general, and the Chambered Nautilus in particular.
The right balance between swift movement (both activated by propellers and jet propulsion), an assortment of visual, chemical and gravity sensors, and high camouflage skills makes it the perfect vehicle for inconspicuous observation of the deep sea biomes.
Pilots often take pride in decorating their own machine with rare customized parts made of copper and gold, coral powder and opal moonstones.
-------------------------------------
This is my very first attempt at building a ship slash mollusk, or any type of vehicle for that matter, out of Lego.
Its name and inspiration actually comes from the sea creature more than the famous fictional Jules Verne's submarine, although the steampunk background was definitely in my mind while building it.
It's been great fun getting accustomed to this new logic and finding new solutions to new problems. Being able to hold the model in my hands while building it was pretty neat too. And the use of a minimal number of parts is both exciting, because it's a fast building pace, and stressing because you can't rely on mass to cover mistakes.
I'll definitely try my hands at another ship model soon, and try to make those damned canopy gaps disappear.
The model sits on a stand from which it can be lifted, and can be swooshed if need be.
Very curious to know what you think of this thing! - Cheers
Finally after watching many tutorials I have cleaned my sensor my self. It took 19 wet swab cleanings to do this with out leaving STREAKS ! Next time it wont take so many.

Die Pixelgröße wird in Mikrometern (µm) angegeben und ist ein Maß wie lichtempfindlich der Sensor der Kamera ist.
Pixel binning is a clocking scheme used to combine the charge collected by several adjacent CCD pixels, and is designed to reduce noise and improve the signal-to-noise ratio and frame rate of digital cameras.
Data binning (also called Discrete binning or bucketing) is a data pre-processing technique used to reduce the effects of minor observation errors. The original data values which fall into a given small interval, a bin, are replaced by a value representative of that interval, often the central value. It is a form of quantization.
Das angeblich naturgesetzliche Problem / diese angebliche physikalische Grenze existiert auch aus einem weiteren Grund so nicht, da es auf einem Denkfehler beruht. Man berücksichtigt nämlich u.a. die Bayer-Matrix nicht. Gemäß dieser bilden 4 Pixel eine zusammenhängende Messfläche, welche 2 grüne, ein rotes und ein blaues Pixel aufzeichnen.
D.h. die aufgeführte angebliche Grenze tritt frühestens bei 100 Mega-Pixeln auf.
4:1 S10 ?
9:1 S20 ultra
Both the wide-angle and telephoto sensors use pixel binning to output higher quality images at a standard resolution, with the telephoto sensor using Nonacell technology which groups 3x3 pixels to capture more light.

mehrere Pixel werden per Ki software zusammengelegt und ausgelesen.
µ (Mü) Ein griechischer Buchstabe, der bei Einheiten für Mikro (ein Millionstel) steht, also ziemlich klein. Ein µ ist also die Umschreibung für "ein ganz winziges bisschen" Oder aber die Kurzform von Mikrometer.
µm
theoretisch;
statt 1.0 µm dann 4 µm
statt 2.4 µm dann 21 µm!!
(Sony RX100II mit 1 Zoll Sensor und 20,2 Megapixeln: 2,4µm pro Pixel
Der Sensor der Sony RX100II hat genau wie das Xperia Z3 20 Megapixel oder S20 Ultra, ist jedoch 4x so groß.
Daher ist die Kamera viel lichtempfindlicher als die beiden Smartphones.
Sony Alpha 7s mit Voll-Format Sensor und 12,2 Megapixeln: 8,4µm pro Pixel)
eine semi-professionelle Nikon Aps-C 300 DSLR kommt nur auf 5,5µm je Pixel
mit Augenmaß - perzeptiven Auflösung
Exakt deshalb verwenden manche Fachleute heute auch den Fachbegriff der perzeptiven Auflösung = der wahrgenommenen Auflösung in Mega-Pixel.
Damit meint man - cum grano salis - das Bildergebnis, das hinten rauskommt, wobei man von genormten, hochwertigen Foto-ausdrucken oder kalibrierten Monitoren ausgeht.
- Und unter Berücksichtigung der perzeptiven Auflösung schmelzen die in der Werbung so plakativ verwendeten Nominalwerte der Sensoren in Mega-Pixel schnell zusammen.
--
Die perzeptive Auflösung steigt natürlich noch weiter - und zwar drastisch -, wenn man an hochauflösenden Kameras auch hochwertige Objektive verwendet. Mit anderen Worten: Ein modernes Objektiv, das theoretisch für bis zu 80 oder 100 Mega-Pixeln gerechnet ist (so etwas wird seit spätestens 2015 als Festbrennweite für entsprechendes Geld von allen namhaften Herstellern geboten) kann an einer alten 12-MP-Kamera evtl. 11 perzeptive MP erbringen, an einer modernen 24MP-Kamera evtl. 23 perzeptive MP und an einer 50 MP-Kamera ca. 45 perzeptive MP. - Und nun erkennt jeder Laie sowohl auf dem Monitor als auch auf dem Ausdruck sofort die Vorteile. Spätestens ab 20*30 cm werden diese auch auf Papierausdrucken im Vergleich sofort jedem Betrachter auffallen.

Bei der digitalen Bildgewinnung mit optoelektronischen Sensoren, wie zum Beispiel bei der Digitalfotografie, versteht man unter dem sogenannten Binning das Zusammenfassen benachbarter Bildelemente (Pixel) in einer Digitalkamera. Durch die Bildung von Pixelblöcken wird eine höhere Lichtempfindlichkeit pro virtuellem Bildpunkt erreicht, wobei sich der Signal-Rauschabstand verbessert, da das Rauschen statistisch verteilt ist. Im Gegenzug wird jedoch auch die Bildauflösung entsprechend der Anzahl der zusammengefassten Pixel reduziert, d. h. das Bild wird gröber.
Neu: Single Take
Alle Kameras machen zugleich ein Photo oder video!
There's also a new camera mode called Single Take, which allows users to capture photos or videos at the same time with different sensors automatically.
All three S20 models can also record 8K videos at 24fps, which will consume about 600MB of storage per minute.

Nikon D7200 versus Canon 7DII
24 -- zu 20 MP ?
real
24 -- zu 40 MP
Noch grotesker wird der Streit zwischen der Nikon D7200 mit 24 Mega-Pixeln und der Canon 7DII mit 20,2 Mega-Pixeln (wobei dies de facto 40,4 Mega-Pixel sind, die immer zwei Pixel zusammen koppeln). Hier stehen 6.000 * 4.000 Pixel gegen 5.472 * 3.648. Dass der Sensor der Canon auch noch minimal kleiner ist, soll hier unberücksichtigt bleiben. Die Grafik macht die de facto minimalen Unterschiede sichtbar. Ca. 5% mehr Rand rundherum sind für die Praxis der Fotografie irrelevant.

Wie groß ist eigentlich ein µ oder Mü oder My?
...
Das Schaubild zeigt eine Schweins-borste, eine Büroklammer, eine Stecknadel, Zeitungspapier, ein Menschenhaar, Zigarettenpapier und eine Spinnfaser im Vergleich. Alles sehr kleine/dünne Dinge und trotzdem sind alle um ein Vielfaches größer/dicker als ein My.
Stellen Sie sich vor, wie es sich anfühlt, wenn Sie ein Haar im Mund oder eine Wimper im Auge haben. Wahrscheinlich wird jeder bestätigen, dass dies ein extrem unangenehmes Gefühl ist. Auch der Stich mit einer Stecknadel tut zumindest im ersten Moment extrem weh, vor allem dafür, dass die Nadelstärke so gering ist. Stellen Sie sich jetzt vor, Sie laufen durch Spinnweben. Auch dieses Gefühl ist extrem lästig. Jetzt sind wir schon ziemlich nah an einem My dran: Eine Spinnfaser ist aber immer noch sechsmal so dick wie ein My.
1 µm - oder 1 Tausendstel Millimeter
Früher stand das µ außerdem für ein Mikron, was einem millionstel Meter entspricht. Heute ist dafür die Bezeichnung Mikrometer und die Schreibweise 1 µm üblich. Daher kommt es, dass das µ auch als Vorzeichen vor anderen Maßeinheiten in der Bedeutung „ein Millionstel“ eingesetzt wird: 1 µg sind beispielsweise 1 Mikrogramm oder 0,001 Milligramm oder 0,000001 Gramm.

Sunset after finding the camera sensor water droplet / snowflake fiasco
Completely dejected from my camera problems, I almost didn't shoot sunset. But at the last minute decided that I might as well go. Drove past the great view from Valley View and it looked really nice... clearing skies. Kept going for Tunnel View, but as I got closer to Tunnel View, it got increasingly foggy. Got up to Tunnel View and it was completely socked in. No view at all. Two other photographers were there, just standing around. Not enough time left before sunset to get back to Valley View.
Just before sunset, the skies cleared somewhat and all three of us got some decent photos. Then the fog rolled back in. We all stared at the fog for a bit. Then the other two packed it up. I said I was going to stay... you always stay until closer to dark just in case. There were two tiny, tiny little clear patches. I saw the local guy hesitating at his car, like he wasn't completely convinced he should leave just yet. A minute or two passes and this scene opens up! We hadn't seen much of Half Dome all day, but there it was! And Bridleveil Falls! And El Capitan! Everything just opened up... from dense fog and nothing to this in a minute or so.
The other two came running back!
The next shot I'll post is from after sunset, in the blue ~30 minutes once it starts to significantly darken, but before it's actually dark.
For both shots, I had to do some clean-up from my water droplet or snowflake camera sensor fiasco, but I also shot in such a way as to minimize the effect of the droplets.
Well what a pleasant surprise this morning. Pre-photokina Canon has released the details on the much anticipated update to it's popular 5D camera (yes, the very same 5D that I love and shoot with every single day).
The new camera will sell for an estimated price of $2,700. It will have a full frame 21.1-megapixel sensor, DIGIC 4 imaging processor and an expanded ISO sensitivity range from ISO 50 to ISO 25,600. It will shoot at 3.9 frames per second (a disappointment to some who were hoping for a faster camera). Canon says that the new camera will be available at the end of November (just in time for Christmas grandma!).
It will also shoot 16:9 full 1080 HD video. The maximum length for videos on the new camera will be 4 GB per clip or 30 minutes, whichever comes first. The new camera will also have an input terminal for external microphones in addition to it's built in sound.
Other features of the new camera include live view shooting and the ability to keep the shutter open in live view mode for quieter shooting (which Canon oddly says will be helpful to "law enforcement" in it's press release). I can't wait to see the follow up advertising campaign on this one, "Real cops shoot with Canon!"
It also includes a much needed dust cleaning system -- dust on the full frame sensor was the biggest problem with the original 5D in my opinion.
Like it's predecessor 5D model the new 5D will not have built in flash.
Apparently there is also a new grip (which looks massive) that will be available as an add on accessory for the 5D which will allow you to transmit images wirelessly to your computer or an FTP server. It's said to include GPS which I would assume would mean that with this accessory you will likely be able to auto geotag your photos.
So will Thomas Hawk be buying one of these bad boys as soon as he can possibly get his hands on one in November? Hell yes! No doubt.
Even if you can't or don't want to spend $2,700 on a camera body though this is great news because the original 5D is sure to drop in price substantially and that is still one of the finest digital SLRs out to shoot with. If you want to pick up an old 5D cheap I'd be scouring eBay for a used one come November.
Along with the 5D Canon also announced an updated version of their popular 24mm f/1.4 lens. The new EF 24mm f/1.4L II USM lens. I have the current 24mm L lens and love it. I'd imagine the new one will be even better.
You can read the entire Canon press release on the new 5D here.

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!

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

To the east of the Silicon Valley is Sunol Regional Wilderness, a regional park with a diverse flora and fauna. We hiked up a dirt road that follows a Alameda Creek until we reached a spot called the Little Yosemite, which has cascading waterfalls and boulders in the creek. On the way we saw a field of thistles, and one with a visitor that had a damaged wing. I only had my crop sensor camera and kit lens with me, so the bokeh is nothing special.
I enjoy seeing flowers, but I am not a flower person, e.g. usually I am not interested in taking photos of flowers. However, I also don't want to limit myself. Experimenting is good, what do you think?
I processed a balanced, a photographic, and a paintery HDR photo from a RAW exposure, merged them selectively, and carefully adjusted the curves and color balance. I welcome and appreciate your critical feedback.

Das Topmodell Optima 1535 Sensor mit Paratronic Verschluss und den Zeiten 15 - 1/1000 s, hochwertigem Objektiv (Solitar S 1:2,8/40, 4 Linsen, Mehrschichtvergütung), einem eingebauten Mischbildentfernungsmesser zur punktgenauen Scharfstellung des Objektives, kam 1979 in den Verkauf für ca. 300,- DM. Die Agfa Optima 1535 war der eigentliche Höhepunkt der Serie. Sie war baugleich mit der Agfa Optima 1035 Sensor electronic, allerdings ohne Selbstauslöser, dafür mit einem Messsucher zur präzisen Entfernungseinstellung. Kleiner Nachteil dieser Kamera ist der Sucher, der nicht ganz so strahlend hell ist wie die Sucher der anderen Agfa Optimas dieser Baureihe. Passend zur Kamera gab es auch das im Design angepasste würfelförmige schwarze Optima-Lux-Blitzgerät (Leitzahl 12), das eine eigene Messzelle besaß und von zwei separaten AAA-Zellen versorgt wurde.

The F124 Sachsen class is Germany's latest class of highly advanced air-defense frigates. The design of the Sachsen-class frigate is based on that of the F123 Brandenburg class but with enhanced stealth features designed to deceive an opponent's radar and acoustic sensors. The class incorporates an advanced multifunction radar APAR and a SMART-L long-range radar which is purported to be capable of detecting stealth aircraft and stealth missiles.
Although designated as frigates, they are comparable to destroyers in capability and size and were intended to replace the Navy's Lütjens class. They are similar to the Dutch De Zeven Provinciën class, in that both are based on the use of a common primary anti-air warfare system built around the APAR and SMART-L radars as well as the area-defence SM-2 Block IIIA and point-defence Evolved Sea Sparrow Missile (ESSM) surface-to-air missiles.

This photo is actually far more interesting than it may first appear. Shot at f16 or f22, if you look carefully there are specs in certain parts of the image.
Dust?
No, apparently not. It is the Leica M9 Kodak CCD sensor coating degrading.
I found this out later that day when I took the camera in for a clean. I will post more about this on my blog soon together with some answers. Please give me a few days as have quite a backlog!

This photo took time to clean up. It suffered from the 'dust' disease. A windy afternoon caused my sensor to gather all the dust it can making it look like its raining big droplets of bokeh. I removed most of it but there are still some left. Too tired to continue so, here it is.

Nikon D800 Photos: Blonde Wavy Hair Swimsuit Bikini Model Goddess with Pretty Blue Eyes
Here is some awesome video I shot at the same time as the stills with the Sony NEX 6 camera with the 1.8 50mm prime lens bracketed to my Nikon D800:

The rich creamy Bokeh off the 1.8 50 mm Sony prime lens on the crop sensor is amazing! Combine the shallow-depth-of-field with Sony NEX-6 latest face-tracking auto focus, and you can see how the moving video keeps the model's pretty blue eyes in focus, while blurring the background! I shot at wide-open 1.8 all day long! :)
