"Inspiration is Beauty"
The Watermark Conundrum
April 30, 2015         (updated on April 20th, 2017)

For this blog post I’m going to step into the quagmire that is watermarking. This is something I’ve toiled over, trying to figure out the best solution for me and my business. If you’re reading this you may be in the middle of your own internal conflict. Considering how difficult a task it was for me to figure out, and the limited amount of information I could gather, I thought it might be useful to share my own trials and tribulations.

a nice image no obstructions.

A nice image no obstructions but not informative either.

Whoa.. What's all that's gibberish!!! This just ruins the image.

Whoa.. What’s all that gibberish!!!
This just ruins the image.

The opposing forces I struggled with were maximizing the quality of my prized images vs. protection and branding. You work really hard to create inspiring and beautiful pictures. The last thing you want to do is smear a giant hot mess of legalese and advertising all over it. On the other hand most of us photographers post images to further our business and attract clients. How do you implement a solution that satisfies both opposing needs. UGH!!!!

After far too much research, taking too many notes, going in too many circles, and way too much tequila. I finally came to the conclusion that the main reason for posting images to the internet is to promote my business. So I can be profitable and stay in the business of making more beautiful pictures! This was a huge euphony for me, coming to that conclusion removed a lot of noise that was distracting.

Coming to the understanding that my images speak for my business, I needed to figure out what and how to brand them. Every marketing/branding book and blog post I’ve ever read, reiterated the same mantra: “To have an effective branding campaign you must be consistent and everything should tie together” Okay, got it!, putting that at the top of my list of requirements.

At this point I know I should brand my images and it needs to be consistent. But what information is important enough to warrant the possible distraction to my beautiful pictures?

My business name seemed the most obvious, but to be honest, I don’t think a business name is unique enough in the current flat world 1 we are living in today. To make sure a potential client or customer finds me and not some other Martin business, I decided my website address would be the most precise target I could provide.

I’d rather start a conversation with someone who’s asking about permissions rather than having one that starts with a DRM take down notice.

Second on my list was a copyright notice. Let’s face it, once you post an image to the internet it’s out of your control and there will be people who use it without your permission. You will have to accept a certain amount of this, the best you can hope for is it to minimize it. It’s too expensive and draining to track down every misappropriated image. So why not be proactive from the very beginning!

Even with the risk of unauthorized use I still think the copyright notice is of great value. Number one, it shows due diligence on my part as the owner to protect my work. Number two, it clears up any confusion to as to whether the image is owned or public domain. Which I think helps people looking for imagery on the internet understand an picture’s provenance.

So adding the copyright notice makes a lot of sense to me. I’d rather start a conversation with someone who’s asking about permissions rather than one that starts with a DRM take down notice.

The copyright message and the website address were the two bits of information I thought were valuable enough to append to my images. The next question is how do I do that without completely ruining the beauty and message of my pictures. For this I looked to the art industry.

All the art museums I’ve been to usually have a small unassuming note next to the art pieces stating things like: the title, artists name, and other interesting facts. Why can’t I do that to my photographs?

Well first off there’s no way I can make sure there’s a little note following my images throughout their travels on the internet. However sometimes that little note is attached to the bottom of the frame. If my information is small enough I could append it to the bottom of my works of art!

This is not a bad solution. People are already accustomed to viewing art and subliminally ignoring frames. Adding something to the bottom of an image would not be much different. My information would be apart the image and minimally obtrusive.

A normal everyday nice pretty image.

A normal everyday nice pretty image.

Same image signed and information appended. I don't think it's very obtrusive.

Same image signed and information appended.
I don’t think it’s very obtrusive.

Now I know what you’re thinking, yea but anyone with simple photo editing software can clip the bar off the bottom. I thought that same thing and this brought me to my next step.

I saw a video produced by Aaron Nace at Phlearn about how to make a signature or logo and embed it into an image. I thought “WOW!” Most of the world’s famous painters sign their work, why not carry on that same tradition.

A nice stylized signature embedded in the image is much more difficult to remove. Not impossible mind you, just more difficult. The added difficulty of removing the signature brings with it an obvious attempt by someone to misappropriate an image. If I ever do end up in court I should have a stronger case that it was deliberate and malicious.

By and large I’m a fairly easy going person and would rather settle any disputes in a normal business negotiation fashion. However, if for whatever reason someone forces me into court, I want the deck stacked in my favor as much as possible. Hopefully by clearly signing and copyrighting my images I’m doing just that.

At this point I think I have met all my requirements: identified my work, labeled the work as copyrighted, how I can be reached, minimized infringements, and maintain the artistic quality of the image.

There is just one last little thing that needs to be addressed. Previously I mentioned that branding needed to be consistent and relative. For me to manually implement all the above modifications on every images I post would prove very time consuming (a.k.a. costly) and wouldn’t be very consistent.

Software automation is the key to solving the consistency and time issue. I know Lightroom has a watermark tool and it works well but it doesn’t address all the features I have identified for myself. For me, a custom Photoshop script was be the best solution.

Being a programmer in a former life, it didn’t take me much to the cobble something together. Realizing a lot of my photography friends are facing this exact same issue, but do not possess the programming skills I do, I decided I would share my work. It may not be exactly what you want, but by providing commented and working code gives everyone an advanced starting position.

FOOTNOTE A:
  So originally I tried to use a mixture of get font by name and some regex 
  but it was problematic. The postscript names in the 'textItem' I was 
  looking for were extremely obscure. 
  (e.g. "Arial" the universal font is "ArialMT")
  If this becomes a problem I can look into expanding this function, but for 
  now just use "verdana" or manually put the font name in.
  
FOOTNOTE B:
  Adobe uses an abstracted syntax for their pathes. This abstracted 
  path will be converted to an OS dependent string before it's passed on.

/*
There are some assumptions this script makes:

  You're familiar with installing scripts in Photoshop. If not,
  basically you need to copy this script to the presets\scripts
  folder and restart Photoshop. The root file name becomes the 
  menu option under file\scripts. If you need more info you'll
  need to do some internet research. A detailed explanation is
  too much for me to describe here.
  
  Your signature file is a Portable Network Graphics (PNG) file.
  The image is white with a transparent background. The code 
  will determine if a black signature or white signature looks
  best for the image. For best result make sure the image is large,
  approximately 2000 x 3000 pixels. the script will scale it to fit 
  the image you're signing.

Here is some more information on using the script:
  
  If you manually fill in the 'SignatureUri' in the user object
  at the top of this file it will assume that file is the one to 
  use and not bring up the file picker dialog box and ask you to 
  select a signature file. a time saving feature for automation.
  
  If the copyright string is wider than the image to be signed
  it will clip the string. I may fix this later but for now I've 
  only had this problem with images less than 400px wide. 
  
  When you're using the script to sign multiple files you can keep
  track of the progress by looking at the image layer name. It will
  say something like 'image (3-32)' meaning it's working on image #3
  of the 32 images you selected.
     
  If you watch the script execute you will notice what appears to be a 
  pause, this is normal. The script is sampling the image and it takes a
  while. It should not last more than 5 seconds or so depending on the
  speed of your system. For performance make sure the move tool is the 
  active tool in the tool bar, for some reason if certain tools like the
  brush tool are active the sampling slows down.
         
  There is a debug flag that will stop the script from automatically
  closing the image when it's done. This is helpful if you want to tweak the
  user values or the code. It will also pop up dialog boxes with internal 
  values it's calculated. 
   
  This script is not 100% perfect, there are some conditions where averaging
  and frequency analysis do not choose the best overlay color (black or white).
  Usually it's where the colors under the overlay are high contrast or very
  complex. These cases are pretty infrequent, however it's recommended to 
  review the signed images once the script is complete.
 
  Feel free to use this script 'as is' or modify it to meet your needs.
  I have taken extra steps in the architecture of the code to make it
  easier for modification. If you're uncomfortable with programming 
  or JavaScript, any skilled programmer should be able to help you out.
  Other than some tricky math this script is pretty simple to read. 
  the Adobe 'Photoshop-CS?-Javascript-Ref.pdf' contains all the application
  object descriptions and is very helpful.

If you want a copy of the script all you need to do is highlight all the code in the window, then copy and paste it into a text editor 2. Once it’s copied to your system you can save it using any name you want with the .JSX extension. If you don’t use the .JSX extension Photoshop will not recognize it as a script. Then it’s a simple matter of putting the file in the presets/scripts folder in your Photoshop install 3.

This delivery method is a little odd, but considering how dangerous it is to download stuff from the internet. I thought a safer solution would be to publish the source code and let users just cut and paste it, eliminating the worry of viruses and other unsavory things.

That’s pretty much my solution to this sticky mess. My images are my businesses calling card, people know they’re managed, potential clients can find me on the internet, the images are aesthetically whole, and finally automate everything so it’s consistent and quick.

I know my solution is not perfect for everyone, but I thought by sharing what I learned, my thought process, and my implementation. I might be able to ease the burden and help you to a quicker resolution. Good luck and best wishes.



Enjoy,
Todd
