Turning a normal scene>arctic scene

The next brief set for this weekly project is to turn a scene we have photographed into an “arctic” (snowy scene). In order to do this I will need a photograph I have shot in 1920 x 1080 resolution. Alex did not clarify what software but I think I will be using Nuke mostly but maybe with Photoshop and Maya. I have created such scenes in Photoshop but not in Nuke so it will e a fun challenge.

Analysing some Snowy scenes. 

I began this process by analysing such scenes! This way I will have visual confirmation what I am envisioning in my head.

Above are two photos that I took a couple of winters ago. I wanted to analyse for my composite scene. What can I note from the above images. 1. The further away something the lack of detail. Almost creating the illusion of a 2d. Furthermore there is a lack of red and greens, focusing more on whites and blues. Browns are more prevalent.


Above are snow scenes as well as VFX built snow films in TV and film. I wanted to create a mood board of this to look at the difference from say my photographs above and this. There is a lot more atmosphere. A huge part in creating VFX is creating a sense of atmosphere. This is something I should consider when trying to create my snowy scene.


Attempt 1 – Shot in 34c in Tokyo this summer

The above I tried to take into account some of the depth perception Sean was talking about during his lesson of Matte Painting. I blurred out the furthest away from the camera and increased the blue as it was further away. Further more from my studies from the above I tried to make the stuff which is furthest away look more 2D. I also added snowflakes in the foreground in order to distract the viewers like Sean said.

I experimented with using rotoscope but in the end sued photoshop to separate the different elements. And work with roto after.


Plotting down some ideas for how I wanted the piece to look like.

Attempt 2 – Photographed in Norfolk two weeks ago

I wanted to carry out another experiment playing around with atmosphere of the piece. A big part of putting such scenes in films.

I really enjoyed paying around changing the tone of a piece through atmosphere and changing the temperature of the image. It is a technique I want to improve more. For instance on this experiment I want to add more realistic snow. I think it looks fake and not realistic I could have added elements of real snow or adding a blur node or grain node to loose the sharpness of the snow.

Other versions

Sketching out ideas

Final Result- Camera tracker


Screen Shot 2015-10-20 at 16.20.44Issue to look into further*

When I rendered one frame, the read node looked different from sequence. I tried to work out this issue however I still don’t know what I did as all the settings are correct and not differed from the this version and the above.

Final node graph, I used the pixel analyser tool in order to grade the intials to fit into the world more. I feel like I can improve on this and if I have some time then I will. I liked the project and I feel like I am beginning to understand nuke which feels really good. I am going to use this next week to get on top of my work and watch more tutorials to clarify nuke further.

Final Video attempt 1

The end result was better than expected. Things I would like to change for my final piece is better matching the shadow colour- Using colour correct or pixel analyser again.

Camera Tracking in Nuke Homework 3 the developent, troubleshooting

Screen Shot 2015-10-19 at 17.30.25 Screen Shot 2015-10-19 at 17.45.26

One of my issues was when I was rendering the shadow pass frame it looked as though the shadow was 3d even though the primary visibility for the initials was unchecked. I troubleshooted this by unticked the cast shadow which resulting in the below result. However when I tested this later on in my progress by ticking it again the 3d shadow was not there. So I do not know if this was a bug in 2015 or just fixed itself.

Screen Shot 2015-10-20 at 03.02.32

Below are some of my experiments with the shadow. I edited the ray trace shadow attributes as well as the light. I wanted it to match the real image and therefore needed to see where the light was coming from, and how other shadows looked. It seemed the shadows in the real image was quite grainy so I tried to match this.

Here is one the rendered frames as you can see the typeface was quite huge which I scaled down, back in maya.

Fixing the problems.

I found this task one of the hardest out of all the homework so far. However in class Alex broke it down with a ball and we was able to work out how to carry it out. I over complicated it so after breaking it down I was able to create the final piece. It worked using a glowing material, a light catching material and using use background and primal visibility in the render stats.

Screen Shot 2015-10-29 at 13.13.13

Here you can see the light without the background, in order for the material to catch the light, so I had to change my animation so it was near the column.

Final Node Graph

After merging the passes into the still image, I wanted to grade it so it was around sunset time. I gave it a slight golden tint. As I have mentioned I really enjoy giving it a grade and changing the atmosphere of the footage.

Final Week 2


Above you can see an image from my maya work, I have been trying to create this but have occurred quite a number of problems. I will be asking Alex to explain and discuss some of my issues. Hopefully allowing me to troubleshoot some of the problems.*

I had created a beauty pass>specular>incandescent are all passes I tried. The beauty pass for some reason was the only one working. Below are the beginnings of my Nuke work. I feel where I have gone wrong is the alpha channel and organising how to input into Nuke.

Weekly task 2 – Initials integration [nuke and maya] The process

Creating the 3d equivalent, entering in camera information and creating a 3d environment using geometry. My issue at this point was entering the plane to line up.

Stage 2

Screen Shot 2015-10-13 at 13.41.19

Animating and adding in initials into the 3d geometry.

Stage 3

Adding Lighting,

I had some issues when assigning Mia to the objects, in the end I chose to use Blinn tool, and change up the features to create a believable glow for the environment. I also added a point light so the glow could emit.

Stage 4

Screen Shot 2015-10-13 at 21.10.55 Screen Shot 2015-10-13 at 21.07.15

Creating a Use background shader – Doing this I think I began to get a little confused.

Stage 5

Creating the passes again really confused me something I will need to verify tomorrow*

The final piece is above. You can also see my node graph as well as the original image. This task took longer than i though and as this was my first ever time using Nuke on my own it was a really good experiment to see what I knew and more importantly what I didn’t. I did get stuck for some time but after researching specific nodes I was able to see where I went wrong. For instance when creating a roto I forgot to apply it to the copy mask and so forth. I spent way to long before I realised. But the great thing is I was able to click on the nodes and physically see what I had done. Another problem I cam across was when I was trying to put the background in and the page changed shape. I troubleshooted this by adding a reformatting node. I think my node graph is simply laid out so I can see the process.

I like my final piece, I wanted it to look very simple and I spent a lot of time trying to get shadowing correct. I also decided I wanted the moonlight to stream in from in front of the buildings. If I had a little more time I would have put in a street lamp. However I liked the night scene. I would like to take all that I have learnt for this exercise for the main brief of integration so it is photorealistic and simple.
