Snow Particles Effect

In this workshop I was taught how to create a snowing effect on a moving photograph. I was taught how to use 3D space using the camera on the canvas of my project. To begin, I needed to import an image from Google that displayed an environment that had views of snow. I then created a new composition for the canvas and dragged the image onto it. From there, I was told insert a new layer ‘Camera’; this allows the developer to create scenes in a 3D space with appropriate viewing angles:

I then clicked on the ‘Active Camera’ button just above the timeline of the application. From here I was able to change the current camera angle of my canvas:

Below you can see that there is white space, this is because we are viewing the project from the top:

In the screenshot below we can see that the timeline now consists of a new layer ‘Camera’. Within the camera layer I can now change the parameters of the element. So for example, position and rotation:

After I had changed the timeline effects of the camera I was required to add a new ‘Null Object’ within the layer tab. This null object was used to link the camera transition with the photograph:

In the Parent placement of the Camera position, I simply clicked and dragged the swirl button towards the Null object:

Below we can see the small rectangle box; this is the null object:

But as we move the position of the camera we can see than the photograph moves the opposite way to the Null object:

I then went onto adding a solid Layer within the composition:

Within the Solid White Layer I had just created I then added an effect to it known as the ‘CC Particle World’. This was added so I could create the particle system for the snow effect.

Within the ‘CC Particle World’ properties i could change the Radius of X so that the particles would fall from a higher distance within the composition because at the moment the particles are coming from the middle of the viewing area of the video.

Below we can see that the particles are now falling from a higher distance because the X Radius has been altered:

In the screenshot below I have changed the Longevity of the particles and changed the particle type to a Faded Sphere so the particles looked more like snow. The Birth Colour and Death Colour were also changed to white:

I then changed the Birth Rate to 30 to make the snow fall slower: I also adjusted the Death Rate to a slight blue colour so it blended more with the background of the sky. After I was happy with my final outcome I simply added the composition to my Render Queue  and exported it to .mov so it could be played on multiple platform types:
