Unreal Engine’s Project Spotlight uses LED walls for real-time in-camera visual effects

24 Aug

Epic Games has showcased Project Spotlight, an Unreal Engine-powered way to capture real-time visual effects in-camera. The company has detailed the work in a new video showing off the system, including its ability to track the camera’s position in space in real-time for a realistic and customizable background.

Rather than filming in front of a blue or green screen for post-production later on, the Project Spotlight system enables filmmakers to shoot in front of LED walls showing the virtual environment in real-time. Creators can digitally manipulate this 3D virtual scene when necessary and the LED walls adjust the on-set lighting for realistic ambient light.

‘No matter what the project is,’ Lux Machina chief technology officer Philip Galler said, ‘creatives always want to see the closest representation to the final product as early on in the creative process [as possible].’

Experts featured in the video explain that because the virtual environment can be adjusted in real-time, the project saves critical time that may otherwise be wasted waiting for changes. As well, people from different departments can work together to determine how the virtual world is portrayed.

The technology was demonstrated at SIGGRAPH 2019 by Epic Games in partnership with Magnopus, Lux Machina, Quixel, Profile Studios, DP Matt Workman and ARRI. Future plans for the system are unclear at this time.

Unreal Engine’s latest demo videos show just how photorealistic the digital world has become

23 Mar

At this year’s Game Developers Conference (GDC), Epic Games showed off a new pair of demo videos that show just how capable its Unreal Engine has become thanks to advanced ray tracing technologies.

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_4654967374″,”galleryId”:”4654967374″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The first video, seen above, is titled Rebirth and showcases just how photorealistic scenes can be when developed with the gaming engine’s technology. The demo, designed by the studio Quixel, highlights how realistic the lighting technology inside Unreal Engine 4 has become.

The demo was created by just three artists who developed it all using a standard version of Unreal and real-world scans from Quixel’s Megascans Icelandic collection. The result is a stunning showcase of textures and details that rival reality, as seen in the gallery of screenshots above, captured from the 4K stream.

The second demo is a teaser for an upcoming movie titled Troll. Still in the works, the movie is a collaboration between Deep Forest Films and Goodbye Kansas Studios. The short glimpse we get of it once again highlights just how realistic the animated lighting is in the scene, with the face of a woman being dynamically illuminated by little fire fairies of sorts.

As for what this means in the world of photography, the possibilities are seemingly endless. Aside from the inevitable point in time when we can no longer tell a rendering from an actual image — if it’s not already here — the ability to replicate precise lighting situations could open up the door to new software and technology that could not only help to simulate lighting setups in the digital world before testing them out in the real world, but also open up the door to adding realistic lighting to scenes and portraits in post-production.

Keep in mind that unless you’re viewing the videos in Google Chrome on a 4K monitor, you won’t be able to see them in their 4K glory. Even in 1080 though, the videos look incredible.

How to Optimize Photos for Search Engines

18 Nov

When I first started in journalism a few lifetimes and two careers ago, a writer had three things to worry about: writing a solid story, getting it in on time, and keeping your editor happy. That was basically it. Today, that list of concerns has grown to include things like keywords, meta tags, headings, titles, internal links, externals links, and– of course– images. It’s almost enough to make someone who typed NBC news copy in the early 80s on a manual typewriter shake his head and abandon all hope of reaching any kind of audience.

seo optimization for photos

Since I’m not that fresh-out-of-college journalist anymore, writing for online photography magazines requires a pretty firm grasp of search engine optimization (SEO)– that is if I hope for anything resembling a decent-sized audience to read my ramblings once I click the “publish” button. If you write your own blog or are responsible for any kind of website content, SEO should be at the top of your list of priorities, too. By now, most people understand the idea and importance of keywords in their web content. A search engine’s basic function is to match your website or blog with peoples’ searches in order of relevance. It accomplishes this task, in part, based on keywords and text from throughout your site. You may think you have a fantastic headline for a post, for instance, but it may not be enough to drive traffic to your site if the language doesn’t match up with typical searches. While sensational headlines may attract print readers, it might be the boring, just-the-facts-ma’am headline that attracts web readers through effective SEO. Had I named this article “Finding a Needle in a Haystack,” nobody researching photography SEO would ever be able to find it.

Since we are photographers, though, making sure our text is SEO-friendly is only half the battle. Yes, we want people to read our blogs or find our professional websites, but we have an added hurdle to cross. We need people to find our photos as well. Think about the millions upon millions of websites dancing around on the web in all of their binary glory. Our SEO choices help search engines like Google understand what is on our websites, hopefully drawing the distinctions that will place our sites above the competition’s in the results list. In order for photographers to do that effectively, however, we also have to be careful about how we name our images.

Search engines primarily work from text and links. Words. That makes it difficult– but not impossible– for them to differentiate between photographs. Think about the last time you searched Google Images and wondered by something totally unrelated to your search popped up in the results. It was, in all likelihood, a result of poorly named images. Since the name may contain the only words associated with an image, it is vital that you give it a name which is optimized for search engines. Let’s face it– IMG_2468.jpg isn’t going to cut it. There is absolutely nothing unique about it, and chances are there a lot of other images out there with the same ineffective name. Even if you rename your photos for your own archival purposes, their new names aren’t going to be much more helpful. When you stop to think about how many searches take place on the internet every day– and how many of them are for images only– you might as well do what you can to make sure they find you and not somebody else.

While this is not an exact science, there are some tried-and-true steps you can take to help your images get the notice they deserve, and– by extension– help direct the traffic to your website that will hopefully lead to more business.

What’s in a Name?

Like I said, DSC_0042.jpg is not your friend. This is, unfortunately, not one of those situations where less is more. When it comes to optimizing your photos for the web, more is more. You have to give each image on your site a unique name which is specific for its intended use. Since DSC_0042.jpg doesn’t tell Google anything about the photo’s content, I have to name it in such a way that the search engine knows (1) something about the content, (2) that I took it, and (3) where it can be found on the web. Suddenly, a simple cookbook photo is no longer DSC_0042.jpg, but has assumed its new identity as “guyer-photography-atlanta-food-photographer-polenta-recipe,” or something similar. Even rearranging the words can have an impact. Choose your words and their order carefully.

Word Separators: Hyphen/Dash v. Underscore.

Word separators help make sure that search engines know what you are trying to tell them. Obviously, we type our searches with spaces between words. The problem is that search engines don’t really know what to do with spaces, so they close them. That’s why things like URLs and image titles (which get linked to URLs) need a dash/hyphen between words. So “food photography” becomes “food-photography,” rather than foodphotography. Until last year, there had been a debate over whether dashes/hyphens were preferable over underscores. In 2012, however, Google definitively answered the question, stating that their search engines treated underscores like spaces, turning “food_photography” into the spaceless “foodphotography.” While it does not have a huge impact on search results, it does have one, so it obviously makes a difference. This, apparently, is one of the few SEO debates that truly does have a right or wrong answer.

Alt Text

Sites like WordPress, and other platforms with visual editors allow you to insert Alt Text into your photos. You should use this field to attach key words, helping to ensure that your images pop up when people search for those words or phrases.

Talk About the Photo on the Page Where it Appears.

Search engines pull data not only from the image URL itself, but also from surrounding text. This is why you may have a better chance of your blog images finding their way to a higher ranking on a search than portfolio or gallery images. If you’re blogging about them you’re talking about them, adding more information for the search to find, rather than gallery images which have no accompanying text.

Size Does Matter.

This is one of those areas where bigger is better. Larger images rate higher in search engine rankings than thumbnails. You should have a good working knowledge of how your site displays images, as well as what its optimum pixel dimensions are. Besides taking full advantage of your site’s ability to display images at their best, you want to make sure you are doing all you can to promote your photos.

Don’t Forget About Social Media.

If you are managing your social media presence properly, it should be a natural extension of your website. Before Facebook, someone looking for a photographer sat down at the computer and used a search engine. While that is still true today, just as many people begin their search on social media, quite often not getting to a photographer’s website until after they’ve checked out their Facebook page. Make sure that you’re not only discussing your photos on social media, but make sure that it points back to the original images on your website as well.

Google Changes Things Up.

Do you remember how in January of this year Google changed how it displays images in it search results?  Suddenly, we went from low-res thumbnails that took you straight to the web pages on which they appeared, to sleek grids of high-quality thumbnails. Gone are the embedded links that automatically launch the pages that host and license the images, offering the best of both world to photographers and the people looking for them. Now, in an effort to make things easier for the person typing in the search, clicking on an image search result opens a second window that gives the choice of whether to click through to the full site. While this might make things easier for people searching for images, it adds another layer of necessity for the photographer to make sure that images are properly optimized for search. If not, the potential client may never click through to the main site.

Google Images' new layout adds another hurdle to cross for effective photo SEO.

Wrap-Up

If you’ve ever asked a photographer to pick their favorite photo from their archives, you probably got some reply along the lines of, “That would be like picking my favorite child.” We can debate the accuracy of the metaphor, but it carries a lot of weight. We protect our photos with copyright laws. yet we are so proud of them that we want to share them with the world. It’s a great goal, but one that has to be approached with an eye towards making sure they are properly optimized to show up in the very searches that can meet– and hopefully exceed– the goal. Optimize photos on your site and you should see a marked difference in where you rank on search engine results.

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″

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.
