YouTuber upscales classic film to 4K/60p resolution using neural networks

05 Feb

Chances are you’ve seen the famous short film ‘Arrival of a Train at La Ciotat (France),’ by the Lumière Brothers at some point in your life. If not, the original 57-second clip, created in 1895, can be viewed above.

YouTube creator Denis Shiryaev used neural networks to upscale and resound the original black and white clip. His efforts resulted in a 4K/60p clip that is quite astounding. The absence of jerkiness and artifacts makes the arrival of the train that much more impactful and shows just how powerful machine learning has become. Watch Shiryaev’s updated version, below:

Five Steps to Benefiting From Social Media Networks for Your Photography

21 Aug

This article is about how I think you can use social media network sites for your best benefit. I am suggesting there is one single thing which you should concentrate on that you can get there with just five steps.

As I have already suggested, I do recommend photography-centric social media networking sites. The one I have used most is Flickr, but I am not endorsing that particular site. Search “social media networks photography” (or similar), and almost any of the sites found will do the job, in largely similar ways. Play around, you might find one which better suits your style, your way of thinking.

Five Steps to Benefiting From Social Media Networks

And much more!

WHAT DO YOU WANT?

This photograph has over 14,000 views and has been added as a favorite 600 times. It is my most viewed and most faved photograph on Flickr. How can that be? Really? What are its merits which cause it to be so lauded?

Five Steps to Benefiting From Social Media Networks

Girls of Bahrain.

The truth is that its photographic merits are VERY limited. I could give you an explanation of why this image has been such a success, but that is not important. What matters is that it helps make the point that “views” and “faves” and even casual comments such as “Great capture, cool shot” mostly mean very little whatsoever.

That is an extreme way of putting it but I’ll stick with it and avoid drawing it out and giving a long justification. However, I think those numbers below mean very little. Though it might have some interest, it is not what you would call a good photograph.

Five Steps to Benefiting From Social Media Networks
THIS IS WHAT YOU WANT!

I have never properly thanked the person concerned, maybe the mention in this article will make up for that.

King of the souq.

I shared this photograph. The comment I received was:

“Another very “Richard Messenger”ish shot. Do all your subjects coincidentally make the same expression, or do you somehow force it out of them? Haha. His somewhat-there-but-still-flat-sort-of-smile looks very familiar to previous portraits you’ve taken.”

I think I knew the truth pretty much straight away, but it took a little while longer to fully accept it. At some point I linked the comment with Rick Sammon’s adage that “The camera points both ways” and realized why too many of my subjects did, indeed, have that same expression. They were simply reflecting my expression.

It is very difficult to make that sort of realization on your own. People pay thousands of dollars to gain such insights. I had received the comment, and great insight, from an honest person, with clearly good intentions, who expressed themselves kindly AND who happened to be right. What more can you ask? Good comments are priceless.

Five Steps to Benefiting From Social Media Networks

Comments please.

What I want, and what I think will move your photography forward too, is comments. Receiving AND making comments has certainly helped me. Unfortunately, it is very unlikely that you can simply post your photographs, however stunning they may be, and expect people to start commenting. You will need to do a little work.

NEED RELIGION?

Five Steps to Benefiting From Social Media Networks

Do unto others.

The Golden Rule is among the values espoused by most religions and philosophies. Of the various versions, this seemed a good, simple way of expressing how to approach making comments.

“Try to treat others as you would want them to treat you.”

Or, on a perfect day, we could turn to Lou Reed.

“You’re going to reap just what you sow.”

However, you want to put it, in terms of religion, philosophy, or pop culture, it is a good principle to hold in mind when you are making comments.

STEP ONE – JUST TAKE A LOOK

Five Steps to Benefiting From Social Media Networks for Your Photography

Just look … think …

You might want to start on the nursery slopes for the first day or two, week or two even. There is a lot to be learned by looking at photographs and keeping the following in mind.

  • Why do you like a particular photograph?
  • How do you think it was taken?
  • What is it that appeals to you?
  • When was it taken?
  • Which equipment was used?
  • Why was it taken?
  • Where?
  • … and so on

STEP TWO – COMMENT!

Here’s the thing. I am not going to burden you with long paragraphs of explanation, give real world examples, or quote academic research. I am just going to tell you that the person making a comment often learns more than the one receiving the comment.

Five Steps to Benefiting From Social Media Networks for Your Photography

Will she? Won’t she?

When you are ready to abandon all buoyancy aids, this is where you jump into the swimming pool. You now begin to sow, so try to treat others as you would want them to treat you. Keeping in mind Kipling’s six mates, you now start to comment.

Just taking the example of Flickr, there are a massive number of groups, with all sorts of specialized interests. You will probably find it productive to browse around, join them, and start making comments within the different rules of each group. Nothing ventured, nothing gained!

My personal rule is that I do not hang around. If a thought does not start to form very quickly in respect of a photograph, I move on. It is, of course, totally up to you, but I suggest that you do not spend too much time scratching your head.

Five Steps to Benefiting From Social Media Networks for Your Photography

What can I say?

As many a politician would testify, “no comment” is better than a rubbish comment.

Then, as a guideline, you might follow a Rule of Threes. Start off by simply trying to say three things (even just two) which you like about the photograph. Three positive comments stating what you think of the scene, how it makes you feel, what you think the story might be, and what compositional aspects you like. You may find it best to stick to only positive comments for a week or two. It is possible that you will start to get reciprocal responses, but you cannot guarantee it.

(To avoid all sorts of complications, but not without some mild embarrassment, I am commenting on my own photographs).

Five Steps to Benefiting From Social Media Networks for Your Photography

River bed scavenger.

  • An unusual and very appealing photograph.
  • I get the impression that the woman is almost lost in what is a much bigger space.
  • The texture is amazing, and the limited color palette really helps draw attention to that.
  • I really like the way the two patches of dry land balance and seem to point to the solitary figure.
  • It is one of those photographs where you immediately start to wonder what the story is and ask what she is doing.

STEP THREE – GETTING TECHNICAL

Then the next step is to start making a comment or two on technical aspects that you think are good, and which you think contribute to the photograph.

Five Steps to Benefiting From Social Media Networks for Your Photography

Innocence captured.

  • This is a lovely picture of innocence.
  • The contrast between her smooth skin and the textures in the shot work well.
  • The muted colors enhance a mood of loneliness, maybe even sadness.
  • It is really effective to see how you have used the bars, and the shape of the doorway in the background to suggest a frame within a frame.
  • The depth of field seems to be perfect, throwing her face into the highlight, concentrating the viewer’s focus.
  • I would be really interested to know what you did in processing this shot.
  • The subject is central, but I think there is plenty happening around the frame to make the image dynamic enough.

STEP FOUR – THEM CHANGES

Finally, you might tentatively start to suggest things that you might change, or which you think might be helpful. Remember – do unto others!

Five Steps to Benefiting From Social Media Networks for Your Photography

Hey, did you happen to see…?

  • I have never seen this view of the Taj Mahal before. It remains instantly recognizable even though it occupies a very small part of the frame. You did really well to find the shot.
  • Having seen your photographs before, I know you do limited manipulation in processing, so very well done on capturing the bird in just the right place.
  • Lovely evening (?) light, with good exposure keeping just the right amount of detail in the right places.
  • I cannot see the EXIF data and would be very interested to know what focal length you used. It looks like a wide angle to get the tree in the frame, yet the Taj Mahal seems quite close.
  • Any suggestions regarding such a good photograph will necessarily be tiny details. If you had just dipped your knees even an inch, I think it would have been even more perfect to have a gap between the top of the right-hand minaret and the tree branch.
  • I wonder of a small crop, perhaps a sixth off the top and the left side, may have concentrated the view.

STEP FIVE – RESPOND

You can always hint, or just ask directly, “Can you please comment on my photos?”. However, my experience is that once you have commented on their photographs, people tend to feel inclined to comment back. Again, this is my personal rule, but I would strongly argue that it is a good one. I try to always respond, or at least acknowledge any comment.

Admittedly, I have not always taken criticism well, but I think I’ve learned to give it more credence, to encourage it. One example of this is if the person commenting suggests something that I can change … a crop, a processing adjustment, changing to black and white … whatever, just do it and post the result. If there is a way of tagging the person, that is likely to help sustain the conversation.

Without being religious or philosophical, can I just give the same advice again, in a different, rather parental way, PLAY NICELY! and remember to say Please and Thank You.

TAKE IT FURTHER

Five Steps to Benefiting From Social Media Networks for Your Photography
There are a quite a lot of places which are specifically aimed at giving a critique of photographs. As you might have spotted, these include the Digital Photography School Facebook group.

CONCLUSION

The single thing you should concentrate on is making and receiving comments. Getting worthwhile comments is your aim. Take some gentle steps, apply The Golden Rule, and you might just develop a good community. You really can benefit hugely from making and receiving worthwhile comments when it comes to social media networks.

Everypixel Aesthetics uses neural networks to judge your photographs

08 Apr

Designers and image editors often have to browse through large numbers of low-quality photographs before they find the stock image that is most suitable for their purposes. Now, a new algorithm has been created to filter images based on their aesthetic value and get rid of the junk before it clogs up your search results. 

Everypixel uses neural networks for ranking stock images and for this purpose has trained the algorithms to judge the aesthetic value of a stock image in the same way as a human would do.

Everypixel’s CEO Dmitry Shironosov said: “Designers, editors and experienced stock photographers helped us generate a training dataset with 946,894 positive and negative patterns. We wanted to create a technology that can measure not only aesthetics of stock images, but their commercial potential as well. This is the main difference between our smart filter and other solutions that exist today.”

The neural network is capable of estimating the visual quality of an image and applies a score to every file which, if working properly, could save many man hours of human image curation. The algorithm is currently in beta stage but you can already test it with your own images on Everypixel. We’re not so sure about the scoring, but the system already looks pretty good at assigning correct keywords. How did your images do? Let us know in the comments.

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.

Google uses neural networks to improve image compression

27 Aug

A research team at Google has developed a way to use neural networks to compress image files in a more efficient way than current methods, such as the JPEG standard. The team built an artificial intelligence system using Google’s open source TensorFlow machine learning system, and then used 6 million random reference photos from the internet that had been compressed using conventional methods to train it.

The images were split into small pieces measuring 32 x 32 pixels each. The system then analyzed the 100 pieces with the least efficient compression; the idea being that it could learn from looking at the most complex areas of an image, making compression of less complex sections much easier.

After the initial training process the AI system is then able to predict how the image would look like after compression and then generates that image. What makes this method really stand out from others is that the network can intelligently decide which is the best way to compress individual areas of a given photo for the best overall result. The method still needs some work, as final results can sometimes look unpleasant to the human eye and the system are not yet capable of testing for this. Nevertheless, the project looks like an important step into the right direction and if the algorithms can be further refined you might soon be able to save even more images on your memory card or built-in device storage.

Elinchrom launches new EL-Skyport Plus system to include hotshoe flashes in wireless lighting networks

05 May

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_9814466852″,”galleryId”:”9814466852″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Swiss studio flash manufacturer Elinchrom has launched the next generation of its Skyport wireless triggering system that allows photographers to include hotshoe flash units in their lighting set-ups. The EL-Skyport Plus system includes a newly designed transmitter that has a swivelling head that the company says helps to optimize reception, while the new receiver features a hotshoe mount for triggering ‘almost any’ brand of hotshoe flash.

The units work via 2.4Ghz radio communications, have a range of 656ft/200m and offer 16 channels with four groups.

The EL-Skyport Transmitter Plus costs $ 89.99 and the kit that includes the transmitter and the hotshoe receiver costs $ 139.99.

For more information visit the Elinchrom website.


Press release:

The Latest Evolution of the Skyport

Introducing the New EL-Skyport Plus System

The next generation Skyport is here and allows you to take full control of your flashes from the palm of your hands.

The EL-Skyport Plus follows the successful launch of the EL-Skyport Transmitter Plus HS for Canon® and Nikon®, for those shooters requiring Hi-Sync. The new EL-Skyport Plus system is compact and robust, using readily available AA batteries. The Skyport Plus offers an extended range of up to 656 feet (200 m) and controls the power of all Skyport enabled Elinchrom flash units. With eight individual frequencies and the choice of standard and speed protocols, there are 16 frequency options, each with four groups. The EL-Skyport Transmitter Plus is compatible with almost every camera. The transmitter head folds down for reduced profile and easier subject viewing while shooting.

Compatible with Most Flash Systems
The EL-Skyport Receiver Plus will trigger almost every flash system and features a built-in hot shoe to trigger speedlights, while enabling them to also be conveniently mounted onto a lighting stand.
When used in conjunction with a Skyport HS Plus Transmitter, most speedlights set at full power can also be incorporated into Hi-Sync applications (using high shutter sync speeds to freeze motion and control ambient light).

“Elinchrom has long prided itself on providing as much control as possible to its photographers. The new Skyport Plus continues that tradition by allowing shooters to take and maintain complete control no matter what they are shooting. When it comes to Living Light, no company does it better than Elinchrom.” said Jan Lederman, MAC Group President.

The Elinchrom Skyport Plus system is retro compatible with the existing Skyport Speed system, and forward compatible to the additional frequencies offered by the latest Elinchrom ELB and ELC units.

Networks of New York: Field Guide to Internet Infrastructure

13 Feb

[ By WebUrbanist in Travel & Urban Exploration. ]

network guide

We tend to think of the internet as something akin to aether, present all around us in the void – or perhaps something traveling down a series of tubes – the reality is much more complex, rich and intriguing.

networks of new york

In an upcoming book titled Networks of New York: An Internet Infrastructure Field Guide, Ingrid Burrington presents an urban variation on a naturalist’s handbook, giving you the tools to tour the real-life objects that are often obscured or simply hidden in plain sight all around cities.

network internet infrastructure handbook

From the author, “New York’s network infrastructure is a lot like the city itself: messy, sprawling, and at times near-incomprehensible. However, the city’s tendency toward flux is a strange blessing for the infrastructure sightseer: markings and remnants of the network are almost everywhere, once you know how to look for them.”

network field guide notes

The story starts with manhole covers and progresses through street markings, which follow a federal color-coding standard: “Orange refers to the broad catch-all of ‘Communications, alarm, signal lines, cables and conduit.’ This means that orange lines can be internet cables, television cables, telephone lines, or other kinds of conduits.”

network deciphering symbols systems

“The markings are sometimes really sloppy, and often in fragments. Sometimes you’ll see several different labels in the same place. A lot of these cables are bundled up together running through ducts under the city.” Suddenly all of the strange acronyms are comprehensible, including but not limited to: CATV, NXTG, T, ECS, RCN, MCI, L3, XO and FO.

field guide example

The book also branches out to cover different kinds of antennas security cameras we are so used to seeing but many of which we do not understand the purpose of at a glance, from subway wifi devices and distributed antenna systems to CrimeEye, MTA and NYPD surveillance camers.

field guide examples

Finally, the authors builds up to the biggest elements of the built environment: architectural structures housing various large-scale elements of internet infrastructure along the city. Some of these are well-known, but the book brings to light a series of buildings less frequently visited, and provides tips on how to identify others.

field guide illustrations

Recognizing “these buildings when looking on the street is not always easy, but one telltale sign is to look for signs of ventilation and cooling systems. Alternatively, look for windows, or more accurately, the absence of them. (Note: on much larger buildings, in particular skyscrapers, vents also could just be a sign of a mechanical floor, the centralized space dedicated to maintaining utility needs for the entire building).”

Why Aren’t Search Engines Making Better Use of Their Social Networks for Image Search?

06 Jun

One thing I’ve noticed more and more over the past few years is what a poor job traditional image search engines do vs. social networks.

By using social information around photos (likes, faves, comments, +1s, etc.), social networks typically produce much superior image search results than traditional image search.

Take this search of Coachella 2013 for example.

Screen Shot 2013-06-05 at 10.45.53 AM
Yahoo Image Search: “Coachella 2013″

Screen Shot 2013-06-05 at 10.46.24 AM
Google Image Search: “Coachella 2013″

Screen Shot 2013-06-05 at 10.47.28 AM
Flickr Image Search: “Coachella 2013″

The first image comes from Yahoo (or is it Microsoft these days, I can’t keep it all straight). It’s not very good. It shows too many images of just the lineup vs. actual fun interesting photos of the event itself.

Google’s image search results are better, but still not as good as many of the images I find on social networks.

Now I may be biased (as I shot this particular event) but I think Flickr’s search results are *far* better than either Google or Yahoo Image search.

I’m working on a project right now to photograph the 100 largest American cities. When I’m researching things to photograph in these cities I almost always go first to Flickr (because it’s the largest database of highly organized quality photos on the web). I will also look at Google+ too, sometimes. Google+ doesn’t have as many high quality images in the total database as Flickr, yet, but I find some pretty good stuff there sometimes still. Most of Flickr’s advantage here over Google+ just has to do with the fact that they are older and have more images indexed.

Lately I’ve also played around with graph search on Facebook for images — I haven’t been very impressed there at all though.

The one place I hardly ever go is to the actual Google or Yahoo image search engines — because the results are so inferior.

Here’s what I don’t get: *why* are the results at Yahoo and Google Image search inferior? Google and Yahoo have access to proprietary internal social data around photos in their social networks, why isn’t that coming through better in the signal for high quality images.

On my example search using Coachella 2013, not a single Flickr photo appears on Yahoo’s first page image search and not a single Google+ image appears on Google’s first page image search.

Shouldn’t these search engines be better mining organically and socially ranked superior content? It’s not that these engines don’t index it, they do, it’s just not ranking well.

Beyond just better image search, Google and Yahoo *should* have another significant incentive to better include their social images into image search.

All things being equal, assuming you could improve image search results, wouldn’t you want to drive more traffic to your own internal social network, rather than to some unrelated destination — and wouldn’t you want to reward the best photographers on your social network with more traffic vs. some random SEO rigged site somewhere?

Why aren’t image search engines doing a better job with social?

Another added benefit to driving image search traffic to your social network, is that the presentation there is usually better, more uniform and consistent. When I’m tempted to go further on an image from Yahoo or Google, I may end up at some odd sized photo, in some odd format. With a G+ or Flickr result I get a strong consistent image experience that I’m familiar with.

As an unrelated topic dealing with image search on Flickr — the best social image search on the web today — Flickr needs to give us the ability to block certain users from our search results. Many popular photographers will pollute image search on Flickr by falsely tagging things that are not in their popular photos, just to try to garner traffic.

Take this search on Flickr for dog for example. So many of the first page results are not photos of dogs at all. Flickr should allow us to block certain users from our search results in order to better refine them. When we block people from our search results, this should also be a signal to Flickr that this user should rank much worse in search. If users get the message that they will be penalized for purposely mistagging their photos, they will be less likely to try and game the system this way, resulting in better image search on Flickr for all of us.
