Surface one: Plastic
Although there are many different types of plastics I am f=more focusing on plastic containers, such as Tupperware and other household storage containers. These two will differ from each other in appearance but they will all have that unmistakable ‘plastic’ look. It is that plastic look that I am after.

A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural.
The following is my description of the different properties of plastic:
- Colour – The colours used in plastics really have very few limits as its up to the manufacturer. However with plastics the colour does tend to fade and can look more pale and dull over time.
- Diffuse – The light on plastic does tend to by quite diffuse, on the plastic containers I’ve researched the plastic is quite cloudy up close and is not as shiny as you might think, causing the light to diffuse a bit like frosted glass.
- Refraction – There is a low amount of refraction in plastic.
- Specularity – There is a kind of mid range amount of specular in plastic normally.
- Gloss – Again with gloss as well as other properties of plastic it differs with the type of plastic, however I would say it generally as a low or medium amount of gloss.
- Transparency – Light can pass through plastics pretty well, however it depends on the thickness, colour and type of the plastic as well as the density. Looking through plastic will tend to make this look cloudy.
- Translucency – Depending on the thickness, colour and density of plastic they can have a high amount of translucency.
- Reflectivity – Plastic does not tent to be very reflective in this case. In other plastics it maybe if polished or made that way. But I would say normally a very low amount of reflectivity.
- Surface – The surface does tend to be rather smooth but also with a slight rough texture up close. This can be a result of the age and type of plastic.

Surface two: A leaf:

The following is a description of the properties of a leaf:
- Colour – The colour reflected of leaves is normally a shade of green. As the leave dies it may turn to a yellow, brown or even red’ish colour.
- Diffuse – Some light is absorbed onto a leave. I would say a medium amount of diffuse.
- Refraction – There is zero refraction on leaves.
- Specularity– There is a low level of specular on a leaf, some may have a shiny spot but it’s still very dull on most.
- Gloss – This does tend to differ from leaf to leaf, but a low level of gloss I would normally say.
- Transparency – A very low amount to even no transparency on a leaf, however held up to a light there can be some seen through.
- Translucency – Light does bounce and pass through a leaf.
- Reflectivity – There is no reflectivity on a leaf.
- Surface – Most leaves tend to be on the smooth side but up close there is an amount of roughness to them. Depending on the leaf of course. They tend to be soft to touch with a slight fury feel to them.
Surface three: Mangos
One of my favorite fruits by far is a Mango, but lets look at the skins texture and description rather than its taste for now.

The following is a description of the properties of a Mango:
- Colour – Mangos are normally a yellow colouring with aspects of orange, red and also green when not ripe yet.
- diffuse – There is some diffuse in a Mango, some light is absorbed.
- specularity – Light isn’t reflected very well from a Mango, it has an almost dull look to it.
- Gloss – Mangos are not a glossy fruit.
- Transparency – A Mango is not transparent.
- Translucency – A mango as a whole has no translucency but the skin may if peeled off and held to the light.
- Reflectivity – Mangos are not at all reflective
- Surface – The surface is a little fuzzy and a bit smooth. Soft with an almost plastic feel to it.
