Light

Posted on Posted in UncategorizedTagged , , , , , , , Leave a comment

What a strange thing light is. It gets into corners, shines brightly and illuminates. You can see it at a distance even if it’s millions or billions of miles away. It might be made up of packets of energy (photons) or waves. It has different wavelengths for different colours and is part of the electromagnetic spectrum. It moves at the speed of light in a vacuum. But slower in an atmosphere or travelling through another medium like water or glass. It can be refracted (bent) depending on the wavelength which is why Sir Issac Newton found it was made up of a spectrum of rainbow colours when he passed a beam of daylight through a prism in a darkened room.

Apart from the scientific details which I only have a sketchy knowledge of, there are lots of phrases that are used in English :

Shed a light on it, light of my life, light at the end of the tunnel, thunder and lightning, the light fantastic, by the light of the stars.

Light is a fascinating subject.

Planning

Now’s the time to order our hanging baskets for the year. The lady that puts them together asks me what colours I would like. Usually I don’t specify what theme I want but I’m definitely going for a rainbow theme this year. I think because there are so many different flowers and shapes and colours that would really brighten the yard. Last year was mainly red white and green so I bought in other flowers to broaden the spectrum.

Going out of the back door and seeing all this colour lifts my spirits. I usually order them and then collect them 6 to 8 weeks later. It’s a bit expensive but I have never been able to grow baskets as beautiful as hers. The summer arrives and I bring the baskets home. Then we have a riot of colour until late Autumn.

Spectra

Spectrum on a silver/purple cushion and a pink blanket. Digitally manipulated to add symmetry and then twist and move the plain of the picture. I’d like to draw over this to try and create a butterfly shape, but I need to learn a bit more about the new app I am using. I love the rainbow colours cast by a glass crystal in a mobile I have hanging in my window. The different cloths moderate the colours and one is more sparkly than the other in the original photo. (Not shown here).

Mirror.

Seen today, a mirror in a shop, reflected branches. And the bevelled edge was shining with the spectrum. I had walked to the shop and on the way it poured with rain. The sun broke through behind me and I took a photo of a rainbow. But the camera did not save the image because I turned my phone off too quickly. So when I saw a similar effect in the bevelled edges I tried to capture those colours. Lots of things inspire me x

Memory. Captain Scarlet

Posted on Posted in Sketching, UncategorizedTagged , , , , , , , , Leave a comment

We had to discuss limited and free colour palettes today. I chose this red car from the children’s TV series Captain Scarlet. It was one of my favourite series when I was growing up. Sometimes a bit frightening. It was about the Mysterons from Mars who were trying to invade the Earth.

Red was my favourite colour when I was little. Not pink, never blue, just red. I don’t know why…..

I found the car in a charity shop and had to have it. I like the limited colours of red, black and silver. I had to have it.

Another Sketchfu drawing

This was a favourite drawing I did at Sketchfu, I can’t remember if it was a challenge drawing or just something I decided to copy because I liked it so much. I enkoyed trying to show the sunlight penetrating down through the water and catching the Orcas back. Its a bit sketchy but not too bad.

Water changes the colours you see, and the deeper you go, the more towards the blue end of the spectrum the colours become. Reds and yellows fade away as you go deeper, until the blackness in the depths of the water absorbs all light. It is at those depths that you start seeing the dim glows of Angler fish. I actually think it would be fascinating to go down in a submercible and to see some of the otherworldly wonders, but I dont think I ever will. But I can use my imagination…

More flowers

Well since all my photos are in my October file it does mean I can find ones that I took last year and I’m also putting them together in blocks so that I might be able to delete some of the individual ones.

I think these were taken out at the Dorothy Clive Garden in Staffordshire (?) , England, last year. Either it was a showery day, or partly overcast because some have shadows and some not. But they were all grouped together which is why I think they were taken around the same time. Other than that they are random and mostly on the hotter side of the spectrum. A lot of them are daisy types, but I’m in love with the poppy too.

White light

Split into colours

Created by sunlight

Rainbows glow

Chemicals create different colours, sodium used in street lights glows yellow. Chemicals are used in fireworks, like strontium (red?) or copper green, creating different colours, blues, purples, oranges.

The reason sunlight is made up of a spectrum is because the sun is made not only of hydrogen and helium but all the chemicals in the periodic table up to iron (any chemicals beyond that can only be created in Super Novae explosions). All the chemicals in the sun glow in different colours, which is why they show up when the white light from the sun passed through a prism. If you split the spectrum further you can find dark lines, these are markers of which chemicals are present. The older the star the more chemicals. As a star gets older it starts to burn up its hydrogen and helium. New chemicals are created by atoms fusing together. That’s where new chemicals are made. When you think about it, if it wasn’t for stars burning or exploding we couldn’t exist.
