I was playing around with the shell extensions, and came upon this. There's enough room to fit various Technic connectors through the gap.
NASA researchers have discovered a perplexing case of a black hole that appears to be “tipped over,” rotating in an unexpected direction relative to the galaxy surrounding it. That galaxy, called NGC 5084, has been known for years, but the sideways secret of its central black hole lay hidden in old data archives. The discovery was made possible by new image analysis techniques developed at NASA’s Ames Research Center in California’s Silicon Valley to take a fresh look at archival data from the agency’s Chandra X-ray Observatory.
Using the new methods, astronomers at Ames unexpectedly found four long plumes of plasma – hot, charged gas – emanating from NGC 5084. One pair of plumes extends above and below the plane of the galaxy. A surprising second pair, forming an “X” shape with the first, lies in the galaxy plane itself. Hot gas plumes are not often spotted in galaxies, and typically only one or two are present.
The method revealing such unexpected characteristics for galaxy NGC 5084 was developed by Ames research scientist Alejandro Serrano Borlaff and colleagues to detect low-brightness X-ray emissions in data from the world’s most powerful X-ray telescope. What they saw in the Chandra data seemed so strange that they immediately looked to confirm it, digging into the data archives of other telescopes and requesting new observations from two powerful ground-based observatories.
This image shows the structure of galaxy NGC 5084, with data from the Chandra X-ray Observatory overlaid on a visible-light image of the galaxy. Chandra’s data, shown in purple, revealed four plumes of hot gas emanating from a supermassive black hole rotating “tipped over” at the galaxy’s core.

Xylography or engraving is the etching technique in which wood is used as a template and allows the playback of the recorded image on paper or other suitable support. It is a very similar process with a stamp.
These hands are one of the best artists from Brazil , Dra . Yolanda Carvalho.
The new armor piece (left) fits nicely with many types of blades from the old sets.
The masks (right) can circle around the new 6 loader. I wanted to make a motorcycle but don't have enough masks.
I don't often post instructions or techniques but though I would just put this out here. Not that great at editing it all together but some might find it interesting. It's the cockpit area from my most recent starfighter - Toxic V1. I built it from memory in LDD, so hopefully its OK. Probably should have chosen a different angle/more colored details for some of the harder to figure out areas. Feel free to recommend improvements or change any part of this to suit your needs. 74 pieces as is.
I had a few of these lying around on my desk, and I realized they make a lovely stone floor texture when combined en masse. It could also work as a cobblestone street. I probably won't ever use it, since I tend to build space.
When building the APC from the movie Aliens, I had to come up with a way to make a sliding door that didn't add too much of a "mechanism" stealing space from the interior. During the whole project I was focusing on movie accurate functionality inside small spaces.
This sliding door is really effective with just a few pieces. The base for the idea is that the thin wall element matches the thin plate of the part holding the door. That makes the door slide sturdy with some friction tight against the wall. The little handle inside to the left keeps the door in place when fully closed. In this example there where not much extra space for anything. I can see how this technique could be developed further for different purposes. Color was an issue as well. For example I'd love to have a 1x1 corner wall element in dark stone, but without it I used the end slope as a stop for the door making the opening slightly narrower than 4 studs which I think helps keeping the sence of minifig scale.

The matte painting (which can be translated with painting backgrounds) is a technique used mainly in film used to allow the representation of landscapes or places otherwise too costly or impossible to reconstruct or reach directly.

This is my first decent double exposure. I make this for a contest on PHLearn.com, and I won!
(There was only permited dodge, burn, and crop) Tomorrow I hope I can edit some cliffs photographs :)
_____________________
Esta es mi primera doble exposición decente. La hice para un concurso en PHLearn.com, ¡y gané!
Sólo estaban permitidas las ediciones que se pudiesen hacer en cuarto oscuro (subexponer, sobreexponer, y recortar)
Mañana espero poder editar algunas fotos de los acantilados :)

Finished what I think are two of the most complicated sections in this design. The roof peak and the balcony had so many details on angled surfaces it took all my tricks to figure out how to fit it all in.

I began experimenting around with lanterns earlier, and Thought I'd share the results. The one in the middle right is pretty basic and common and the one on the right I saw somewhere else (hopefully they don't mind), but I decided to include them anyway. Hope you like them!

The Photochrom technique for printing "colour" images started in the late 1880s. As I said previously it required three black and white negatives to be colourised Red, Green and Blue (RGB).
I could give you a range of different results, but I'm only going to show you a couple of outcomes. I have used the same black and white image in each case so that we can make a genuine comparison. In this case we have three fully saturated images and when combined we get the result above.
It is an interesting comparison with the 50 percent saturation. In this fully saturated version we get a sky that appears in the clouds to have some colour about it, but the blue in this case seems to balance the red.

I like to play with processing of star trails now and then. Here I used my "Blobulous" technique to make the final position of the stars stand out. I also used the "Smoothee" technique and, of course a poor-man's dark frame subtraction.
Sounds difficult? No? It's all pretty easy and I've got a great description of these techniques all set to publish soon on my BLOG.
The red is garish, I agree. If I decide I want to, I can use the techniques described in "foreground-o-matic" to replace this tree with a different manifestation of the gnarled bristlecone.

How the wheels were assembled for the 6952 remake I built.
This was also the technique I used for the wheels on my Futuron Rover.
can be refined, but this is the current technique. most is plates and tiles, but for the diagonal track use 2 x 1 x 2 slope bricks on their sides.
Just discovered this while sorting my pieces. Not entirely mathematically accurate, but creates a nice texture with pieces that are widely available in an average LEGO collection.
Can be repeated ad infinitum.

Technique: My sister in law's Lavender is loaded with all sorts of creatures. Unfortunately I didn't get to get to her place in the mountains above Itri, Italy until about 10:00 AM and the light wasn't ideal. So I shot with the sun in front of me to back light the subject and hopefully get a break in the contrast.
Tech Specs: Canon 80D (F8, 1/1000, ISO 800 with highlight tone priority) + a Canon 100-400mm F4-F5.6 L II with IS enabled. Natural light with the subject back lit. This is a single, uncropped, frame taken hand held.
I continue to experiment, and expand my technique. Recently I began working with a tripod shooting flower and insect macros. Tripod works very well indeed for making sharp images, but has a big drawback. Once those three legs are planted, it is awkward to try to reposition the camera / tripod to follow moving insects. Even shifting it to get different point of view can be challenging...though everything is doable if one works at it. And finally, when photographing close in, in garden settings, it can be difficult to find places to put the three legs.
So I took out the monopod, to see how it might deal with these issues. Leg placement is much better, shifting position is very easy indeed. Changing camera height is much simpler as well. The downside, as one might expect, is that it is not nearly as stable as a tripod. Though the Z-axis (up and down) is fixed, side to side movement, and front to back movement is not. The best counter to such movement while shooting is the camera's burst mode...hoping to grab exposures in between any involuntary movements.
This is the first photograph I'm showing done using the monopod. I think it safe to say that when it works, it works quite well.
Ok, I finally got around to putting together my remaining time lapse seqences.
These sequences were shot on August 5th, 6th and 3rd respectively.
The last one was my first attempt at capturing a sunset time lapse, I should have let it go on for longer. While I improved my technique for the other two, I think the sky was more spectacular on that first attempt. The video compression hasn't done this upload any favours but I think its viewable...
All 3 sequences were shot on a Nikon D700 and Nikkor 14-24mm f/2.8G at 14mm.

ps. appreciate the sentiment but no .gifs or badges please.
Here are a few more visor techniques I found and have queued up. I like to save them until I use them before I post, but they're starting to overflow.
I don't know if some of these have been found but in the case that they aren't, I'm posting them here.
p.s. I still have a ton of techniques that I haven't shown yet.
I really wanted a 1 x 2 cheese slope stuck on each end of that girder. The one end was easy, but the other was not. That's pneumatic tubing around the minifig hands. The 1 x 2 plate helps to hold it, but isn't necessary.

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.

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.
