WK 9 - rendering techniques, cameras and lighting.

For my final lesson this week i learnt how to render out work, created in a suitable manner to gain the highest possible visual quality,  i learnt that there are three main points to consider when reaching this point of a task , these being the light set up ,the model surface, texture and finally the camera , which i learnt the next points how to create effective lighting and shadow rays which add realism to the objects. I learnt that there is generally a three light system , these being the main , fill and back light, through simple exercises shown i was able to ceate different shadows and pick up certain textures in an area set to do so, setting a frame to work with in an area, global illumination was used and mental rays to create reflections and other effects. This reference gives amore in depth reasoning behind the imaportance of setting a scene using good lighting techniques:

This reference shows a clip were these techniques are used to create realistic lighting and rendering:
I used this reference as the landscape of paris shows a perfect example of the use of lighting and reflections


I found that these aspects of the tutorial were extremely useful to my own interests and relevant, as many professional practices use these techniques throughout there productions in windows , characters eyes and water etc. in which case it is a crucial factor to learn for future practices .
As regards to the success of my work for this, i found it was not successful as i had hoped as i would like to have the reflection on the floor more green and i could not do so after many attempts. I found it hard to navigate between all the different aspects when using illuminations and combining mental rays. Below is the example of work created in the tutorial:


To further develop my practices i would like to spend a great more deal of time using these effects as i can see how useful and effective they are in professional films shown . I want to learn those a lot more and also develop my knowledge in cameras areas were i would like to learn factors such as hand held camera effect and panning over objects and around them.
I plan to do this before my final soundscape project were i feel these effects would be effective and original in my own way if can possibly achieve this, or at least reach a standard were its basic. I hope to achieve this in the next week or two.
