New Samsung image sensors use dual pixel for fast AF and fake bokeh

13 Oct

Samsung Electronics has launched a couple of new image sensor—both intended for use in mobile devices—under its ISOCELL sensor brand—the ISOCELL Fast 2L9 and the ISOCELL Slim 2×7.

As the model name suggests, the ISOCELL Fast 2L9 is part of the Fast line-up, providing fast autofocus speeds, even in low light conditions. To achieve this, the chip is using dual-pixel technology with two photo diodes at each pixel location. This not only speeds up autofocus but, according to Samsung, also allows for creation of a software-based bokeh-effect without the need for a dual-camera, which is more or less what Google’s new Pixel 2 devices do.

The 12MP sensor comes with a 1.28µm pixel size, which is slightly smaller than the 1.4µm currently used in Samsung flagship phones.

At 0.9µm, the pixel size is even smaller on the second new sensor, the Slim 2X7. Like the Fast 2L9, it is designed to fit into even very thin devices without the need for a camera bump, but this one comes with a higher 24MP pixel count. In low light, the sensor combines the image information captured by four neighboring pixels to increase sensitivity and reduce image noise, a process which Samsung calls Tetracell.

Like in other ISOCELL sensors, Deep Trench Isolation technology is applied to improve dynamic range and reduce color crosstalk on both sensors.

Looking at the technologies used in these new sensors it is evident that as a maker of both hard and software, Samsung is an excellent position to design its sensors with computational imaging applications already in mind. Unfortunately, there is no information yet on when we’ll see the new sensors integrated in actual devices.

No dual-cam? No problem: Patch app for iOS uses neural networks to create fake bokeh images

11 Nov

Most dual-cam equipped smartphones offer a ‘fake bokeh’ feature. Thanks to the slightly offset position of their two lenses, cameras in devices like the Apple iPhone 7 Plus, Huawei P9 or LG G5, can distinguish between objects in the foreground and background of an image. By applying digital blur to the latter they can simulate effects of shallow depth-of-field you would typically achieve with a DSLR and fast lens.

If your phone just has one camera, there are still a few pure software solutions out there to achieve the same effect. The Patch app for iOS is the latest and uses neural networking to identify the foreground subject in an image and isolate it from the background. If the scene is too complex for the algorithms to work automatically, there is also a manual selection tool that can be used to optimize the results. You can paint in areas that should be sharp, and remove areas that should be blurred. A zooming function allows for greater precision in this task. 

Once the selection is finalized users can choose from 5 different blur strengths to generate the desired effect. Patch does not have any particular camera hardware requirements and therefore works with most iOS devices. If you want to try the app you can download a free version that will leave a watermark on your images from the Apple App Store. A $ 1 in-app purchase will get you an upgrade to the watermark-free version.

How to Avoid Fake Smiles in Your People Photography

03 Feb

DPSarticledee_cover750

A genuine smile is one of the most attractive expressions of the human face, and as photographers, we love them because they brighten up our pictures with warmth, and create connection.

When you look at it on a body language level, you discover that a genuine smile informs others that we are:

  • A friend, not a foe
  • Happy
  • In a good place mentally.

It’s a universal safety and happiness cue that we recognize on an instinctive level. It draws people in, and creates a sense of positive connection with the person in your image.

I’ve been talking so far about a genuine smile, because a smile can also be deceiving. We humans have developed the ability to fake smile when we want to pretend that we’re happy or friendly, even when we’re not… and this happens a lot in front of the camera.

DPSarticledee_danimontage_750

Let’s face it, standing in front of a lens is not the most happiness inducing moment in most of our lives. To many people, this is actually really uncomfortable, but yet you are asking them to smile, which often ends up looking tense and fake.

What a fake or tense smile says about the person in the image, is that they are not being honest, that they are uncomfortable, or even submissive.

People will fake a smile to appease others, when:

  • They are nervous or uncomfortable
  • Showing submission
  • Being polite (when someone cracks a really bad joke for example)

No matter the reason, a fake smile will give off a low-power impression of the person in the image.

So what’s the difference between genuine and a fake smile?

  • A genuine smile is visible mainly in the eyes. Smiling eyes are relaxed, with raised cheeks, and a nice tension appearing on the side of the eyes. The mouth can be anywhere from slightly raised or wide open, but it’s the eye action (not the mouth) that communicates the honesty of a smile.
  • A fake smile on the other hand, will have no, or very little, eye engagement. The mouth smile can still be very wide, but you will not see any action in the upper cheek and eye areas. It looks more like a grin, than a smile.
  • The expression of contempt is often mistaken for a smile. The most obvious sign of disdain is a one sided smile, with the lip slightly pulled up.

DPSarticledee_smilesmontage_750b

How to get a real smile? Don’t say cheese!

As a portrait photographer, your job is not only to make a beautiful image, but also to be the director of the shoot, helping your subject relax into the right emotion. If your subject is uncomfortable, you’ll most certainly end up with a fake smile or worse, an expression of contempt, and lose the warmth and honesty that comes from a genuine smile.

It has become a habit for many photographers to shout out, “Say cheese!!!” to get someone to smile in front of the camera. But this method usually ends up with embarrassed grins, or fake smiles, instead of genuine ones.

So what should you do instead?

It’s impossible to fake a feeling (unless you’re a sociopath) and the only way you can get your subject to genuinely smile is to help them connect with a real feeling of happiness. Asking them to think of something, or someone, they love allows them to connect with a genuine feeling of happiness, and you’ll see their cheeks raise and create a beautiful honest smile within seconds. As soon as you see it, let them know so they can feel it for themselves, and reproduce it. I ask my clients to give me a keyword for what they just felt and I use that for the rest of the shoot.

If they can’t think of anything, you can tell them a funny story, or a joke, and that can work really well, but can be a two edged sword if the joke falls flat and makes the situation very awkward instead.

Smiles are also a very useful barometer of your clients comfort level. If they can’t seem to relax and connect with a happy thought, it’s a good time to check your own body language and see if you are sending off stress, or discomfort, cues that they are mirroring back to you.

Differences between men and women

Contempt

Genuine smile

Smiling is recognized universally as a sign of happiness and safety, by both women and men, but there are a few differences:

  • For women, smiling is a way of creating rapport and a sign of appeasement, but to men a smile can come across as submissive.
  • Men smile less often, and less widely than women.
  • Women are attracted more to photos of men smiling, but men prefer more serious photos of other men.

When coaching your client on the image selection, it’s important to know the usage they are going to make of their photos. A man needing a photo for a dating website would probably have more success with a smiling photo than a serious one. But if he’s looking for a job in a male dominated workplace, then he’d probably be better off choosing a more serious one for his LinkedIn profile.

Brandalism: 600 Fake Ads Call Out Climate Conference Sponsors

11 Dec

[ By WebUrbanist in Design & Guerilla Ads & Marketing. ]

paris climate reality

In a massive coordinating guerrilla marketing campaign, 82 artists from 19 countries produced and installed 600 convincing false advertisements around Paris, all targeting major polluters and corporate backers of the COP21 Climate Conference.

Orchestrated by Brandalism, these installations were professionally executed, placing real-looking adverts behind panes of glass at bus stops and street corners around the city. The aim: to raise awareness of corporate interests in the talks, particularly those with high fossil fuel consumption, and attempts by such companies to greenwash their behavior and appear to be on the side of sustainability.

paris we are sorry

The works came in all forms, from political cartoons to stark photographs showing the realities of climate change and impacts around the world. Some highlighted the roles of specific brands while others spoke more generally to the consequences of global pollution left unchecked.

greenwashing conference talks

From the organizers: “Amidst the French state of emergency banning all public gatherings following the terrorist attacks on 13 November in Paris, the ‘Brandalism’ project has worked with Parisians to insert unauthorised artworks across the city that aim to highlight the links between advertising, consumerism, fossil fuel dependency and climate change.”

Robot City: Entire Fake Town Built to Test Driverless Vehicles

23 Jul

[ By WebUrbanist in Technology & Vehicles & Mods. ]

7/15/15               2015 UM Aerials -July                 MCity, North Campus, Munger Grad                            Residency,Campus construction.

Opening this week, Mcity is a completely artificial village for self-driving cars, bringing the future of automobiles back to Michigan, the historical home of Motor City. Taking lessons from military testing facilities like Gravesend in England or Yodaville in the US, the complex is made to simulate a wide variety of conditions.

fake town driverless cars

Featuring 32 acres of roads, intersections, sidewalks, streetlights, signals and building facades, Mcity is part of a statewide effort to advance connected technologies and test autonomous vehicles. More than a simulated combination of urban and suburban environments in their ideal forms, these experimental grounds also incorporate stress-testing defects like graffiti and faded lane markings as well as different street terrains, tunnels, roundabouts and multi-lane freeways on a combination of pavement, cobblestones, gravel, grass and dirt.

fake city autonomous vehicles

Given that all crashes to date involving autonomous cars have been caused by human error, it is critical not only to test the vehicles themselves but also the people they will interact with on the road. In addition to its proximity to Detroit, a key benefit of the Ann Arbor area is the varied weather in the area, with everything from hot humid midsummer days to serious rain, snow and hail in the winter. The test area can be reconfigured on demand to simulate complex intersections, blind corners and other real-world challenges.

fake city university michigan

The project represents a $ 10,000,000 private/public partnership between the University of Michigan, local governments and various industries, including but also beyond regional and international automotive powerhouses (Ford, GM, Honda, Nissan, Toyota but also State Farm, Verizon, and Xerox).

7/15/15 Aerials of UM Campus and Ann Arbor.

“We believe that this transformation to connected and automated mobility will be a game changer for safety, for efficiency, for energy, and for accessibility,” said Peter Sweatman, director of the U-M Mobility Transformation Center. “Our cities will be much better to live in, our suburbs will be much better to live in. These technologies truly open the door to 21st century mobility.”

“In addition to Mcity, MTC has three on-roadway connected and automated vehicle deployments underway. With the help of the Michigan Economic Development Corporation, MTC is building on a nearly 3,000-vehicle connected technology project launched three years ago by the U-M Transportation Research Institute to create a major deployment of 9,000 connected vehicles operating across the greater Ann Arbor area. MTC is also partnering with industry and the Michigan Department of Transportation to put 20,000 connected vehicles on the road in Southeast Michigan. The third piece of the plan calls for deploying a 2,000-vehicle mobility service of connected and automated vehicles in Ann Arbor.”

Lending a Hand: Selfie Arm Lets You Fake Your Friends

02 May

[ By Steph in Design & Products & Packaging. ]

selfie arm 5

Never mind that given its skin tone, this arm-shaped selfie stick kind of makes it look like you’re dragging a corpse around. Mounting your cell phone onto the end of it to shamelessly selfie away in public places might make you look ridiculous to bystanders while you’re doing it, but at least in the finished photos, you appear to be having a great time with a living companion.

selfie arm 4

selfie arm 3

Artists Aric Snee and Justin Crowe collaborated on the ‘Selfie Arm,’ which is exactly what it sounds like. Poking fun at the self-photography phenomenon and examining the relationships between humans and technology, the device is thoroughly tongue-in-cheek. Ten limited edition, signed copies of the prototype will be made.

selfie arm 2

selfie arm 1

Lightweight and portable thanks to its fiberglass construction, the Selfie Arm also makes for a conversation-starting accessory if you walk around with it poking out of your bag, so maybe it can actually help you meet a human companion who will take photos for you – no fake severed limbs required.

Gravesend: Fake Town for Simulating Crimes, Riots & Terrorism

19 Nov

[ By WebUrbanist in Travel & Urban Exploration. ]

artifical street urban complex

Like the set of a movie or setting of a video game, this surreal suburban facility could easily be mistaken for a real place at first glance – in reality, the installation is an elaborate artificial environment used by police to simulate complex and dangerous situations (photos by Chris Clarke).

artificial empty building facaDE

As Geoff Manaugh summarizes the setup, “the barren streets and hollow buildings of this militarized non-place were designed for use as an immersive staging ground for police-training exercises, fighting staged riots, burglaries, bank robberies, and other crimes” including hostage situations and terrorist attacks.

artifical training ground building

Located in Gravesend, Kent, just outside of London, this strange facsimile of an urban complex is devoid of residents but comes complete with parks, nightclubs, estates, aircraft, trains and tube stations (for hijacking and bombing simulations). Its population, instead, consists of the ebb and flow of the Metropolitan Police, of which the complex accommodate up to 300 militarized participants at one time.

artificial city for police

Open “in 2003 to provide London’s officers with firearms and public order training,” the complex’s designers at Advanced Interactive Systems (AIS) “provided all specialist firearms-related design, fit-out of the live-fire ranges with internal ballistic and anti-ricochet finishes, simulation and targetry equipment, and range sound systems.”

artificial backdrop city street

The same company was later contracted to “upgrade the specialist indoor shooting ranges and simulation systems [to] feature High-Definition projection systems, additional support for standard issue firearms and less-lethal devices, laser-based 3D virtual training environments, and a course editor for creating bespoke training exercises.” Even these official descriptions lend themselves to a range of dystopian speculation and dark interpretation.

artificial complex urban tube

Author of Subtopia, Brian Finoki notes that this dull gray place is deeply bizarre in nature, “a city standing on the planet for one purpose: to be rioted, hijacked, trashed, held hostage, sacked, and overrun by thousands of chaotic scenarios, only so that it can be reclaimed, retaken, re-propped in circuitous loops of more dazzling proto-militant exercise, stormed by a thousand coordinated boots for eternity, targeted by hundreds of synchronized crosshairs of both lethal and non-lethal weapons.”

artifical commercial street facade

Photographer Chis Clarke, whose Flickr photo set is worth seeing in its entirety, suggests a bold take on the complex and its meaning in the contemporary cultural context of the United Kingdom: “Gravesend can be interpreted as a warning – a prophecy of society’s potential to alienate itself from itself, and kill its collective identity. This surreal installation serves as a chilling account of the death of community in 21st century Britain.”

Fake Perfect Fall Colors Using the HSL Tab in Lightroom

08 Nov

It can be extremely hard to predict when and where the peak colors of falls will hit. If you’ve ever been a week or two early you’ll know the frustration of seeing little splattering of color when you were hoping for full on peak color. Well, using a little bit of post-production magic, you can add some life to those early fall shots and get it closer to the vision you’d hoped mother nature would’ve given you in the first place. Let’s see how we can fake fall color using the HSL tab in Lightroom!

before&after

As a side note: I do want to mention that while this article is about faking the colors to create a vision that didn’t exist in the first place, a lot of these techniques can be applied to enhancing fall colors that do exist. Even if you’re completely against the idea of changing the world in post-production it might be worth reading through it to see how you might be able to use these techniques in a way that retains a more true to life look in your image.

What is the HSL tab

HSLThe workhorse of the manipulations you will see today is the HSL tab in Lightroom. It allows you to control the Hue, Saturation, and Luminance of your photograph on a color by color level. This gives you the ability to modify reds separately from oranges, blues from greens and so forth.

Each of the HSL controls have a unique slider for the eight different color tones that make up an image and as you’d expect, each of the HSL controls allow you to modify different aspects of that color.

  • Hue – Controls the tonal range of the color that you’re modifying. For example greens can be anywhere from yellow to aqua.
  • Saturation – Controls the intensity of the color that you’re modify. More saturated means deeper and more intense color, less saturated and you’ll have muted or even no color for the selected color.
  • Luminance – Controls the brightness of the color you select. Moving a slider to the right will brighten the selected color, while moving to the left will darken it.

As you can see there is a wealth of specialized controls built into the HSL tab. I hope the walkthrough below gives you some ideas on what you can do with it. Remember it’s not just limited to faking the colors of the fall season.

Fake perfect fall colors with Lightroom

To get started you’ll need a photograph to work with. It is going to be important that you choose your images carefully here as not every photograph will work for this kind of post-production.

For example – you’ll want to make sure that the trees you’re featuring do in fact change color in fall (evergreens do not), and, that the other surrounding features of your photograph are outside of the green/yellow spectrum that you’ll most-likely be changing, or you’ll be altering them as well as your trees.

fall

Once you have a great shot and you’ve completed some of the basic post production steps then you’ll want to hop over to the HSL tab in your Lightroom develop module.

As you’ll be working with trees that have yet to change color you’ll mostly be working with greens and maybe some yellows or reds. Again, this is why it’s important that the photograph you’re modify doesn’t contain any non-leaf items in these color ranges – or you’ll change them too – and that might looking more unnatural than the fake fall colors you’re creating.

fakingfallcolor-green

As you saw above, the shot I’ve chosen for this article contains mostly green leaves with just a few hints of fall color. The first step is to remove the greens from the image by moving the green’s hue slider all the way to the left. This effectively changes the green colors in the image to yellow giving a more fall like look the the photograph, but we’re not done just yet!

Next you can experiment with moving the reds and yellows sliders around to try and see how they effect the image. Different color tones will come to life that you may not even realize were there in this step so it’s important to take it slow and look at the entire photograph as you make the changes. In this image the leaves on the ground took on a rusted red look while the trees themselves got a deeper orange look.

fakingfallcolor-hue

Once you’ve got the Hue the way you like it you may want to move into the Luminance and Saturation tabs of the HSL tool. This will allow for further modifications of the colors tones by effecting the richness and brightness of the colors you’re presenting.

fakingfallcolor-luminance

Remember the color tones are still the same as they were in the Hue slider, so even though the greens appear as yellow, moving the green Luminance slider to the right brightens the trees a bit, while the orange and yellows sliders effect their respective color tones.

Another idea that you might want to toy around with is modifications of the white balance. Adding more yellows with the Temp slider or more magenta with the Tint slider can add even more dimension to the shot giving the colors a more dynamic feel.

fakingfallcolor-wb

However, it is extremely important to be careful with the white balance sliders when you’re doing these manipulations as bad things can happen very quickly if you’re too aggressive with the changes!

fakingfallcolor-toomuch

After you’ve set your color tones and adjusted the white balance of the image it’s time to give the entire photograph a good, close, once over.

For this demonstration image the lettering on the sign started to take on a reddish/yellow tint after the white balance tweaks were performed. To fix this an adjustment brush was added to the sign which reduced both the Temp slider (to remove yellows) and the Tint slider (to remove the magenta colors). Also at this point the sign was given a little more definition with the adjustment brush by increasing the clarity and fine tuning the exposure.

fakingfallcolor-adjustment

All in all using the HSL tab in Lightroom can be a fun way to create that fall color when it might have been just out of reach. Of course, this doesn’t compare to the real thing so, the best way to get fall color is to go find it in person. Therefore don’t let this stop you from getting out and planning your next hiking trip – the unpredictable nature of the fall season is one of my favorite parts about it!

Virtual Light: Facade Installation Casts Fake Illumination

30 May

[ By WebUrbanist in Art & Installation & Sound. ]

facade light cast installation

A temporary project set in Madrid, this bright yellow artistic reconfiguration was rendered all the more engaging due to its location in a semi-dark alleyway of the city.

It was created by (fos), an alliance of artists and designers (the word meaning ‘light’ in Greek and ‘melted’ in Catalan), utilizing the front of a vegan restaurant in the semi-secluded Lope de Vega street.

A combination of sun-bright yellow tape and paint were deployed in a pattern intended to abstractly simulate the casting of light, surrounded by shadow, with a few artistic liberties taken in terms of angles and scope.
