Creating Depth in Art, Film, and Photography

Although 3D imagery is becoming more prevalent in blockbuster films, the fact still remains that depth is something established in 2D imagery.



A recent post on zevendesign.com outlined 8 pain ways to establish depth it art, photography, and film.

  • Atmosphere 
  • Color
  • Linear Perspective
  • Light
  • Shadow
  • Solidarity
  • Focus
  • Movement


We've all read or watched something that teaches us about creating depth, but the examples they used in this post were so beautiful and unique I found it necessary to share.


1. Atmosphere

The man stands holding an axe in front of the misty forrest that slowly fades off in to the distance. This form is depth is created by having the background less clear then where you want the focus to be.




2. Color

Maybe I'm just a color kind of guy, but I find this form of depth to be the most interesting. The repetition in color palette reveals some of the science behind creating depth.  


The opposite is also true with a white background.



3. Linear Perspective


Linear Perspective is probably an obvious one and usually one of the first ways we thing of creating depth. It's what your second grade art teacher called "the vanishing point". All of the material in your drawing is aimed at one focus point.




4. Light

Obviously if you point your light on to what's in the foreground the attention is going to focus there. But in this post they used light to show that when something is lit in the background, you get a very interesting effect. 



 In the picture below I feel pulled in to the scene. That path is beckoning for some quality strolling down.

The Light here is used in a much more metaphorical way. The focus in this painting ties in to religious beliefs on where our focus should be in life. Although we may first look at the man, that is not where the attention is pulled in the painting. 

5. Shadow


One the flip side of the last one, attention can be brought to what is not in the light by using shadows.





6. Solidity 


Solidity refers to the level of detail in different parts of the image. Solidity differs from focus in that it is usually used in cartoons and paintings. With this technique, the foreground has more attention detail then what is in the background.



7. Focus

Focus is the most common way to achieve depth in film and photography. It can also be achieved in computer art and animation, as they show in a couple of these examples:



 And hence forth the term "Bokehlicious" was created. 

8. Movement

Movement is another common technique used in film in photography. When your subject is on the move, moving the camera with them can blur stationary elements and bring focus to the subject. 


Which is also a synthetic effect I used in our promotional poster to give depth to the room:

The opposite of this (stationary subject with a moving background) is another way to achieve this effect. (Shout out to that time we made Cracked).




Of course, many of these examples are not limited to their exemplified use. Often times, it is the combination of several of these techniques that create depth in a scene. It's up to you to decide which ones will fit your image for the right effect.

Blurring Logos in After Effects

For the past two years I have been blurring logos for “Company X” (A well known company I won't mention). At first I blurred them using Motion but after Final Cut X came out, they did the big switch to Adobe so I had to figure out the best way to do it in After Effects. I have been blurring for about 5 hours straight today so I figured I would take a break and write about it because my eyes are actually going blurry.

I feel like there is a much easier way of blurring these logos using a different technique or software like DaVinci but as of now I have to do it the long and monotonous way. In case you were itching to know... this is my everyday process:
  • Company X sends me footage using a highly secure transfer software.
  • I download it and bring it into After Effects. 
  • Sometimes they send me an e-mail with notes and time code for each package which I refer to throughout the process. 
  •  I play through the layer of video once and then start at the beginning. 
  • When I find the first logo I need to blur I create an adjustment layer. I set in and out points for that layer/logo. 
  • Then I create a mask covering the logo. 
  • The next step is adding the blur. The blur I use is called “fast blur” and I also add some feathering so the blur better blends with the surrounding area.
  • The intensity of the blur depends on the size and clarity of the logo. 
  •  Now frame by frame I move the mask to follow the logo using key frames.
  • However,  if an important character moves a part of their body partially in front of the blurred mask I have to create a subtraction mask. AKA my WORST nightmare. Not really but it’s just an extra step.
  •        In order to create a subtraction mask I duplicate the original video layer and drag it on top of the blurred layer. I create a mask around the character’s obstructing part in the duplicate video layer. 
  • I follow that object using key frames until it cuts to the next shot or the character stops obstructing the blurred mask.
  •         And then I repeat these steps for the remainder of the package.

          A final blurred shot looks a little like this….. (but with Company X's footage)



           A typical package has 40 adjustment layers instead of 7 but you get the idea. I know I could potentially use motion tracking with this but I found that when you have footage that whips/pans very quickly and the logos aren’t clearly defined, motion tracking takes longer than just doing it by hand. So I hope you enjoyed this extremely boring blog post as much as I did. Now back to blurring I go!
