Shutterstock’s new watermarking system foils Google’s AI

27 Aug

Following a study Google released last week showing how easily an AI could remove watermarks from stock images, stock photography website Shutterstock has introduced stronger watermarks that are more difficult to eliminate using automated software. Google notified the stock photography company about the vulnerability before publishing its research paper, and it seems the company took their warning in stride.

Google’s technology works via a computer algorithm that learns to identify the common elements in many stock images—that is, the watermark—and then remove just those elements without altering the underlying photo at all.

Google ultimately identified the consistency of watermarks as their main point of vulnerability. To counteract the vulnerability, watermarks needed inconsistencies that involved ‘random geometric perturbations.’ In other words: the marks should be warped to avoid consistency across the entire photo library. Doing this confuses the artificial intelligence, and results in watermark artifacts being left on the image after attempted removal.

Stock photography website Shutterstock has already implemented an improved watermark system based on Google’s advice. With its new system, stock photos are protected by watermarks that are applied with slight geometry changes, making it impossible for an AI like Google’s to figure out precisely which pixels belong to the watermark versus the image itself.

“The result was a watermark randomizer that our engineering team developed so that no two watermarks are the same,” says Shutterstock CTO Martin Brodbeck. “By creating a completely different watermark for each image, it makes it hard to truly identify the shape.”

Firmware update adds watermarking and improves user interface of DxO ONE

08 Jun

DxO has released a firmware update for its ONE connected camera. The main additions in firmware version 1.4 are support for copyright/author metadata as well as watermarking. Users can now preview aperture and exposure compensation settings in real-time on the ‘viewfinder,’ better known as an iPhone or iPad. DxO has also tweaked the user interface, with quicker access to camera and app settings. And, as with most firmware updates, overall camera performance has been improved.

Version 1.4 of the DxO ONE app for iOS is now available in the iTunes Store. The camera firmware is updated via the app.

Press Release:

DxO ONE continues to redefine mobile photography with v1.4 update

A new streamlined user interface helps protect your photos with integrated copyright and watermarking support

PARIS—June 8th, 2016—DxO announced today the immediate availability of another major update to the multi-award-winning DxO ONE Miniaturized Pro Quality Camera™ for iPhone® and iPad®. Continuing with the promise to make the DxO ONE even better after you’ve bought it, version 1.4 adds integrated copyright/author and watermarking support to help protect your photos from unauthorized use. In addition to important performance enhancements, the update also features a dramatically improved user experience that puts all of your capture and application settings in their own, quick-access menus.

“Like my DSLR and tripod, the DxO ONE has become an important part of my workflow, allowing me to instantly share high quality, high res photos with my clients and followers”, said noted motorsports photographer, John Thawley. “By adding integrated copyright info and watermarking support, I can be confident that my shared DxO ONE images are now protected from unauthorized use.” 

Since its initial introduction revolutionized the world of mobile photography, literally dozens and dozens of new features have been added to every DxO ONE via automatic (and free) software and firmware updates. Photographers the world over told our team they love the instant sharing capabilities of the DxO ONE, but wanted a way to better protect their work. DxO’s engineers responded by providing the ability to automatically embed copyright and author info directly into the EXIF data of every DxO ONE photo. In addition, version 1.4 introduces the option to automatically add a watermark to photos shared to Instagram, Twitter, Facebook and every other photo sharing service supported by Apple iOS.

As more and more sophisticated controls have been added to the DxO ONE iOS app, the design team in Paris determined through exhaustive usability studies, that access to these controls could be even more efficient. The resulting version 1.4 update sports a streamlined user interface that provides one-tap access to capture settings, all of which are now logically grouped in a consolidated design. In addition, application settings, such as the Message Center and online support, can now be accessed with one tap from the Gallery view. The net result is that the bright, beautiful Retina viewfinder of the iPhone is now far less cluttered, leaving more room to compose your DxO ONE images.

“DxO has a world-class design team in Paris that values direct user feedback above everything else,” said Kirk Paulsen, consulting CMO for DxO. “They continue to innovative at a breakneck pace, adding exciting new features and useful controls with each successive release. It’s remarkable how far the DxO ONE has advanced in less than a year since it was first introduced.”

Version 1.4 also introduces a host of other features based on direct user feedback, including the ability to preview in the viewfinder, in real-time, camera controls such as Aperture and EV-bias. Users can now determine when they want their DxO ONE to go into power saving mode, and all-important firmware updates that unlock new features and functionality are now more visible via top-level notifications, so you’ll never miss the opportunity to take advantage of cool new ways to control your DxO ONE.

Every DxO ONE camera includes free access to DxO Connect, very simple but extremely powerful software for Mac and PC, that can make your best DxO ONE photos look even better. DxO Connect v1.4 now leverages the new DxO OpticsPro 11 engine, which includes even more remarkable noise reduction for high ISO, low-light images. The new processing engine also makes use of face detection to automatically extend the dynamic range, add fill light, and improve contrast while optimizing illumination on faces in your photos. DxO Connect can even automatically add microcontrast to sharpen fine details in your images, but it’s smart enough to leave those details intact with photos involving faces or with those captured at a high ISO in low light. Mac users, who use OS X Photos as their primary photo editing software, may want to download the updated extension (DxO OpticsPro for Photos – DxO ONE Camera only) from the App Store, which lets you tap into the power of the new DxO OpticsPro 11 photo engine without ever leaving the Photos app.

Pricing & Availability

The DxO ONE Miniaturized Pro Quality Camera™ for iPhone® and iPad® is available for purchase at dxo.com, Amazon, Best Buy, B&H, Target and other respected retailers for only $ 499 (US).

The DxO ONE iOS v1.4 app and companion Apple Watch app are both available for free via the iTunes App Store. New firmware, also immediately available, can be downloaded to the iPhone and installed on existing DxO ONE cameras with a simple tap. The 1.4 updates to DxO Connect and ‘DxO OpticsPro for Photos – DxO ONE Camera only’, are also immediately available for existing users to download from dxo.com and the Mac App Store, respectively.

How to Watermarking Images With Photoshop and Lightroom

30 Sep

Have you seen the writing on images? You know, the little pictures or words that show the photographer’s name? Those are called watermarks. Photographers often watermark their images so that they are properly credited for their work. Here are a few ways to watermark images with Photoshop and Lightroom.

Watermarks using Photoshop

You can create watermarks in Photoshop several different ways. Here are a few of them.

1. Text layer

The first way is to create a text layer. This is great for simple word watermarks. You can then write your name or your photography business’ name. From there, you can adjust the opacity as you see fit. Try adjusting the blending mode to achieve the look you want. To get the © symbol type; option+g on a Mac, or Alt+0169 on a PC.

Normal blending layer with black font at 100% opacity.

MonicaDayDPS-Watermark-03

Normal Blending Mode with an opacity of 63% in black font.

MonicaDayDPS-Watermark-04

Overlay Blending Mode with a black font color at 100% opacity.

2. Logo file

If you have a logo you can place it on your image. You want to make sure your logo has a transparent background. Usually, this will be a PNG file, a GIF or even a vector graphic. If you are unsure, check with your logo designer. Use the place option to put your logo on your image. Again, you can adjust your opacity and blending modes to get the desired effect.

Place function in the Photoshop CC menu. You then choose the file you’d like to place.

MonicaDayDPS-Watermark-07

Place the file and adjust the size as you wish. (Hold the Shift key down as you resize to maintain the aspect ratio and proportion of your logo)

MonicaDayDPS-Watermark-08

You can again adjust the opacity and blending mode to get your desired look.

2a. Making your logo background transparent if it isn’t already

If you have a logo file that does not have a transparent background then follow these simple steps to create one. First, open your file in Photoshop. Go ahead and unlock this layer (double click it, then hit Enter).

Watermark-01

Watermark-02

Background layer locked

Watermark-03

Layer is now unlocked.

Next, use the magic wand to select the background. If the background is not a solid color then select your logo image and then invert the selection. Now that your background is selected, simply cut. You can do this with cmd+x (Mac) or ctrl+x on a Windows computer.

Watermark-04

Select the background only.

Your image should now have a transparent background. Save this file as a .PNG (JPGs cannot hold transparency) and you’re ready to go.

Watermark-05b

Where you see the grid pattern it’s now transparent.

3. Using the brush tool

For an even easier way to watermark, create a brush. This way you do not have to go through these steps each time you want to watermark your images.

To create the brush with text you’ve written you will need to open a new document in Photoshop. Make sure your document has a transparent background. Type the information you want to have on your watermark. Make sure you have it set up exactly like you want it on your images. Once you have your watermark just as you want it you should go to Image > Trim > Transparent Pixels. Next, Edit-Define Brush Preset. Name your brush and you’re ready to go. The same process can be done with your logo file.

MonicaDayDPS-Watermark-09

These are sample settings that work well in most cases. Make sure your background is set to “Transparent”.

MonicaDayDPS-Watermark-10

Notice that the font is written very large.

MonicaDayDPS-Watermark-11

Make sure you trim your watermark text.

MonicaDayDPS-Watermark-12

MonicaDayDPS-Watermark-13

Your trimmed text should have no space around it.

MonicaDayDPS-Watermark-15

Define your brush in the edit menu.

MonicaDayDPS-Watermark-16

Give your brush a descriptive name.

MonicaDayDPS-Watermark-17

Notice that your brush is now in your brush menu. You can see it at the bottom right in this picture.

You can now use your brush as you would any other brush. The key to having it watermark is to create a layer and select the brush that is your watermark. A simple click will watermark your image. You can adjust the size, opacity, and blending mode as your like.

Watermarks using Lightroom

Lightroom has an awesome feature built-in that allows you to watermark your images upon export. In order to use this feature you must first set up your watermark, to do that go to Lightroom>Edit Watermarks.

Screen Shot 2014-09-16 at 5.49.22 PM

You can choose an image or text. There are several different settings that allow you to adjust your watermark like you want. Remember, to get the best results you’ll want to use a PNG file with a transparent background. If you don’t, you’ll have a white box around your logo. You’ll need to save and name your watermark.

For a text watermark simply write your desired information in the white box. You can change the font, color, shadow, and size of your watermark. Watch the image to see your desired effect. Use the Anchor option to adjust placement and the Inset option for further tweaks.

The font, opacity, size, and location can be altered as you like.

Make sure you use a logo file with a transparent background to avoid this white box. JPEG files do not have transparent backgrounds.

Now that your watermark is all set up, let’s apply it to your image. Go to Export and Watermarking. There you can choose whatever watermark you have setup. Your image will be exported to the desired location with the watermark chosen.
