A value/light/color study of a city at night.
Reference from here
This one was about Color and Light. More precisely I read and took notes from one chapter of J.Gurney’s book. This part is about different sources of light.
In direct sunlight there are 3 different sources of light: sun, the blue sky and reflected light from illuminated objects.
You can think of the skylight as a soft light, coming from many directions.
The higher the altitudes and the clearer the air, the sky will be more blue-violet and shadows darker and bluer relative to sun.
As more clouds show up, shadows become grayer. The more haze or smog shows up, shadows are tonally closer to the value of the sunlight.
The color of the ground and nearby objects reflects into the shadow areas.
-soft illumination (because clouds diffuse sunlight)
-this eliminates dramatic contrasts of light and shadow
-ideal for complicated scenes
-colors appear brighter and purer than in sunlight
-it is easier to show patterns of costumes
-the sky is usually the lightest note
-light comes evenly and equally from above
-good for photographs cause you expose a scene evenly
-if the sun is not shining directly through, the light is bluish
-you can get nice contrasts together with another source of artificial light inside (cool-orange for example)
-on a sunny day light shines on the ground and bounces up through the window and on the ceiling
-depending on colour of the ground, you can see orange or green on a white ceiling
Candlelight and Firelight
-weak, drops off rapidly
-no deep darks next to the light source, but glowy appearance and many soft edges
-it is a point light (think starburst shape).At twice the distance, the light is only 1/4 as bright. At 3 times the distance, it drops to 1/9 as bright.
Indoor Electric Light
It has 3 qualities: relative brightness, hardness/softness, color cast
The brightness depends on wattage, lamp type, how close the subjects are, how bright the other lights are
Hard light comes from sharp, small points like spotlight or sun. It is more directional, more dramatic, casts crisper shadows, brings out more surface texture and highlights
Soft light comes from a wider area (ex:large panel of fluorescent tubes over a workbench). It is more flattering and reassuring. It is better for task lighting because there are weaker cast shadows. The tonal transitions are more gradual.
The color cast depends on the dominant wavelength. The regular incandescent tends to be strong in orange and red and weak in blue.
Standard warm white and cool white fluorescent light emphasizes yellow-green.
Streetlight and Night Conditions
-blue-green moonlight can contrast nicely with warm lights in shops and streetlights
-gas light is weak
-modern light: incandescent, fluorescent, neon, mercury vapor (cool, drains flesh color), sodium vapor (sickly, warm, narrow wavelength), led lights
bioluminescence- light from usually ocean creatures, mushrooms, insects. It is usually cool, blue-green and the colors gradate from one hue to another.
Best to paint the scene in dark tones and add glows at the end.
fluorescence- light produced by an object that converts invisible light (amber, calcite)
Hidden Light Sources
Light can come from outside the picture, inside the picture or it can be concealed but inside the picture. The hidden one is more intriguing. Can also be used for silhouettes, pools of colored light, emphasis.
I have been very frustrated lately that it is so hard to find good watercolor sketchbooks in Europe. I realized I had lots of paper and cardboard I wasn’t using, so I decided to invest in a few tools for making my own. So far it seems like a very wise investment.
I used a wonderful tutorial for most of this by Otterluv. However I added a few things to help when on the run (a pocket at the back and an elastic to hold it closed tight). I started with some tools, but I ended up ditching some and adding others. I also used paper glue. The blue paper was never used cause it was not big enough.
So, left to right: packing paper, hole punch, craft knife, elastic, fabric, waxed linen thread, bookbinder’s needle, double sided tape, strong glue, ruler, scissors, 300g watercolor paper and an A3 cardboard from an used pad. Also used an old brush and a wooden bookmark for spreading the glue.
Can’t wait to use it 😀
Yeeey, more speedpaint. I made this one in a bit under 2 hours, since there was quite a bit of perspective there. I used reference from here. To be honest, this was more about practicing light rendering/high key painting. You might think all you see is white walls. But it is so much more color there. I soooo want to go to Santorini at some point.
This time it was studying, taking notes and applying what I learned from a chapter of Color and Light, one of the most useful books for a painter, by James Gurney.
Today’s ticket was “Speedpaint”. The goal is to do around 30 of these with photo reference in the near future, then start riding without the safety wheels and go all crazy creative in 30 mins.
I had photo/painting ref from here. Took me 55 mins and way too much browsing through my brushes.
