Satellite: Sentinel-2. Sensor: MSI (MultiSpectral Instrument).
Visualization RGB: bands 12 (red), 11 (green), 4 (blue). False color urban.
La imagen tiene 63 km de ancho (aprox.).
Esta combinación de bandas, habitualmente utilizada para destacar las zonas urbanizadas, es también útil para los volcanes pues permite discriminar con bastante claridad las diferentes coladas de lava.
Tarso Toussidé, a broad volcanic massif at the western end of the Tibesti Range, is capped by the Toussidé stratovolcano, constructed at the western end of the 14-km-wide ignimbritic Yirrigue caldera of Pleistocene age. The 6000 km2 massif was constructed over a basement of Precambrian schists on the east and Paleozoic sandstones on the west. The summit contains numerous fumaroles and very youthful lava flows that would be of historical age in an inhabited region (Vincent 1992, pers. comm.). (volcano.si.edu/volcano.cfm?vn=225010)
Al sureste de Toussidé se encuentra la caldera Trou au Natron (la que contiene la mancha blanca y azul en la imagen) (también conocida como Doon o Doon Orei), de 8 por 6 kilómetros de ancho. Su borde, de 700 a 1.000 metros de altura, está cortado en secuencias de lavas y conos volcánicos más antiguos. En algunos lugares es casi vertical. En el interior de Trou au Natron se encuentran cuatro conos volcánicos basálticos recientes, el más notable de los cuales es el Moussosomi, de 75 metros de altura, que ha hecho erupción un flujo de lava.

How AT&T Building was Named the “Batman Building”
There is no mystery as to why the AT&T Building is known as the “Batman Building.” Towering above the Nashville skyline, the architecture features two pronounced towers on either side of the broad ends of the building. These features resemble the ears of the iconic batman logo. It doesn’t hurt that the building was constructed during a decade that featured four films with the caped crusader (five if you count 1989’s Batman). ~ scalemusiccity.com/why-the-att-building-is-known-as-the-b...

My sensors indicate an intruder is present.
Welll, in proportion to the robot's size, these sensory and controls are quite small.
The B-9, Class M-3 General Utility Non-Theorizing Environmental Control Robot was featured in "Lost in Space."
The Robot featured a glass bubble sensor unit with moving antennae and possessed powerful computers that allowed him to make complex calculations and to deduce many facts. He had a variety of sensors that detected numerous phenonema and dangers. He was programmed with extensive knowledge on many subjects, including how to operate the Jupiter 2 spaceship. His construction allowed him to function in extreme environments and in the vacuum of space. He was extremely strong, giving him utility both in performing difficult labor and in fighting when necessary. Moreover, his claws could fire laser beams and, most frequently, a powerful "electro-force" that was similar to arcing electricity.

I finally decided to upload some of the shots I have been taking with the Ricoh GR IV... I started playing with this one and I guess you could say it's the first time I really processed the files. It held up well I think.
I remember it was freezing out. It was nice to be able to have my camera and my hand in the coat pocket at the same time.
The Agfamatic 200 Sensor uses 126 cartridge film introduced by Agfa in 1972. The exposure is controlled using four "weather" icons above the lens barrel, the shutter release button is bright orange/red and has a solid "click" when pushed.

Testing out an infrared sensor I picked off of the auction site, works pretty good. I put a 3.5 mm plug on it and hooked it to the camera axe. Model number is E18-D50NK.

Amazing. I finally cleaned my sensor and I'm overjoyed with the clean skies! This is pretty much right out of the camera, no cloning out dirt spots. Taken in Felicity, CA, just this side of the Arizona boarder.

The first thing to say is that each electronic sensor has a protective filter over it, so we are not actually touching the electronics. That would be a disaster. Most people send the camera off for a service and a clean and that's a very good idea. After all this is an expensive investment and we want to make sure our camera works as well as possible for as long as it can.
But, it is quite easy to clean your sensor at home. All you need is a kit (like the one I've shown). This includes sealed sterile swabs and a little cleaning fluid (they are essential - do not try to clean your sensor with a cloth where you can scratch the dust into the sensor filter). There are also many videos on YouTube showing you how to use these dust cleaning swabs, but provided you get the right size for your camera (mine is full frame) a simple swipe will suffice.
For a DSLR you obviously need to lock your mirror up before the clean, and then lower it immediately afterwards. Then with the other side of the swab give your mirror a quick wipe as well. Do not apply too much pressure. After all, these are only tiny dust particles - you should not have any dirt.
My Leica D-Lux 7 which I used to take these pictures has a fixed lens, so it will never need its micro-four-thirds sensor cleaned.
Introduction to CMOS Image Sensors

Although the sensor is very old and very low resolution, a super sharp badass lens like the 50-150/2.8 can push an extra portion of details from the small image, and it´s pretty usable for the web and small prints. Of course to use this old technology is not really practical - but it´s a good feeling to be able to get something usable from it, when most normal users would never touch it.
APS-C and 35mm sensor cleaning kits came in the mail this week, photographed on white paper.

Encara que parega que el sensor estiga brut, realment són gavines volant i avisant del temporal que s'apropava.

I'm currently film testing this little beauty, it has been tested and cleaned up with a new colour and some tlc. She's ready to rock and roll all over again! On sale very soon!
Agfa Selectronic Sensor 35mm Film Camera
This is an exposure made with a tiny retro TLR CHUZHAO Camera. This shot used the full color “filter.” The focus mode was automatic. The 12 Mp sensor did a creditable job capturing the subject. One has to remember that this is a tiny camera. Hand held indoors with light from outside.
This photo has had a fair amount of post shot editing. I do the same with iPhone and other camera photos. I took several shots to get this single good one. This is as close as possible to still achieve focus with this little TLR.
