Ask me anything   I'm a twenty one year old animation student and photographer in Belfast. This blog follows my journey through my creative highs, lows, lessons learnt, research, photos, ideas, sketches, quotes, videos, and Maya breakdowns.. ENJOY!

Colour Temperature 

Above is an example of what we learnt in todays lighting class about lighting colour changing with the temperature from the bulb wattage. 

Lighting

Color temperature comparison of common electric lamps

For lighting building interiors, it is often important to take into account the color temperature of illumination. For example, a warmer (i.e., lower color temperature) light is often used in public areas to promote relaxation, while a cooler (higher color temperature) light is used to enhance concentration in offices.[8]

CCT dimming for LED technology is regarded as a difficult task, since binning, age and temperature drift effects of LEDs change the actual color value output. Here feedback loop systems are used for example with color sensors, to actively monitor and control the color output of multiple color mixing LEDs.[9]

Aquaculture

In fishkeeping, color temperature has different functions and foci, for different branches.

  • In freshwater aquaria, color temperature is generally of concern only for producing a more attractive display.[citation needed] Lights tend to be designed to produce an attractive spectrum, sometimes with secondary attention to keeping plants alive.
  • In a saltwater/reef aquarium, color temperature is an essential part of tank health. Within about 400 to 3000 nanometers, light of shorter wavelength can penetrate deeper into water than longer wavelengths (see Electromagnetic absorption by water),[10][11][12] providing essential energy sources to the algae hosted in (and sustaining) coral. This is equivalent to an increase of color temperature with water depth in this spectral range. Because coral, typically living in shallow water, receives intense, direct tropical sunlight, the focus was once on simulating this with 6,500 K lights. Higher temperature light sources have become more popular, first with 10,000 K and more recently 16,000 K and 20,000 K.[citation needed] Meanwhile, actinic lighting is used to make the somewhat fluorescent colors of many corals and fish “pop”, creating brighter “display” tanks.

Digital photography

In digital photographycolor temperature is sometimes used interchangeably with white balance, which allow a remapping of color values to simulate variations in ambient color temperature. Most digital cameras and RAW image software provide presets simulating specific ambient values (e.g., sunny, cloudy, tungsten, etc.) while others allow explicit entry of white balance values in kelvins. These settings vary color values along the blue–yellow axis, while some software includes additional controls (sometimes labeled tint) adding the magenta–green axis, and are to some extent arbitrary and subject to artistic interpretation.[13]

Photographic film

Photographic emulsion film sometimes appears to exaggerate the color of the light, as it does not adapt to lighting color as human visual perception does. An object that appears to the eye to be white may turn out to look very blue or orange in a photograph. The color balance may need to be corrected while shooting or while printing to achieve a neutral color print.

Photographic film is made for specific light sources (most commonly daylight film and tungsten film), and used properly, will create a neutral color print. Matching the sensitivity of the film to the color temperature of the light source is one way to balance color. If tungsten film is used indoors with incandescent lamps, the yellowish-orange light of the tungsten incandescent lamps will appear as white (3,200 K) in the photograph.

Filters on a camera lens, or color gels over the light source(s) may also be used to correct color balance. When shooting with a bluish light (high color temperature) source such as on an overcast day, in the shade, in window light or if using tungsten film with white or blue light, a yellowish-orange filter will correct this. For shooting with daylight film (calibrated to 5,600 K) under warmer (low color temperature) light sources such as sunsets, candlelight or tungsten lighting, a bluish (e.g., #80A) filter may be used.

If there is more than one light source with varied color temperatures, one way to balance the color is to use daylight film and place color-correcting gel filters over each light source.

Photographers sometimes use color temperature meters. Color temperature meters are usually designed to read only two regions along the visible spectrum (red and blue); more expensive ones read three regions (red, green, and blue). However, they are ineffective with sources such as fluorescent or discharge lamps, whose light varies in color and may be harder to correct for. Because it is often greenish, a magenta filter may correct it. More sophisticated colorimetry tools can be used where such meters are lacking.

Here’s a summary of my notes during the lighting and camera fundamentals class

Aperature
Shutter speed
Sensitivity
Focal speed
Exposure
Exposure is the quantity of light allowed to reach the photographic film. 
Sensitivity,ISO,film speed is the sensitivity to film. The more sensitivity the more grain etc. 
Aperture is the hole that allows light to reach the sensor.
Shutter speed is the amount of time the light is allowed into the camera. 1 over 50.
When aperture is low, shutter needs to be longer in order to catch. 
Human vision vs camera lens
40 degree lens create more human presence than a wide angle lens. Therefore adds a more viewing. 
Lmask allows you to see the viewpoint when scouting. 
Focal lens allows you to zoom in and focus on an area. 
Colours become more intense when you bring the aperture down. When working with textures such as pearls and velvet they will suck the light to them. 
Workshop. 
Look at lab colour language. Universal colour language. Raw is lab. Look at black magic cameras. 
Depth of field. Aperture changes the depth of field. A quicker shutter and high aperture creates a stronger depth of field. 
Funel light ➡️ same light I use to create a rim light effect. 
Cant change aperture without compensating in shutter speed. 
The longer the lens the more shaking you’ll see. Wide angle lens can create barrell effects and are best used from below looking up. Tilt shit lenses.
Compression in photographs based on angles as you move up and down. Don’t focus too much on zoom always walk around the subject to figure out which one is best. It’s a better disapline. 
Using the space to compress things in best way to capture the action. Eg. Wide angle might work to catch the vast openness of the scene. 
Soft box creates a soft light unlike a flash which is a harder light. Bouncing is the softest type of light eg. The use of a reflector. The use of work lights that hang can be used to capture eye makeup. In some cases the shape of a light is important in cases of reflective textures. 
Lighting wotage determins the colour 4300-4700k is roughly neutral light. 800k is red. 12-20,000k  is more violet and blue. This should be considered when artificially lighting a set that all bulbs are the same voltage or else the use of coloured gels to keep consistent. If not neutralised colour will fill the colour of the shadow, if a red tinted and blue tinted are the used the lesser of the light will tint the shadow. If the blue is the bigger light the shadow will be a red tint unless reflected back out. 
All of this will apply the same when rendered properly out eg. In Arnold this will be effected. 
Spot lights and flood lights. A funnel lens focuses the light this narrows the spill of the light. Spot light is a direct circle of light but a flood light is a larger circle of light. 
Bouncing - can be used with umbrellas (like me!) 
Diffusing - using a white diffuser to slow the light down as it travels. Can then aim the light at the object overall making light more focused and much softer looking. 
Flagging 
Coverage - different heads can be used to create different coverage of light. 
Fill
Intensifying - adding a black reflector will increase the shadows. 
Size relative to the subject. Closer light sources become softer. Sunlight is harsher because it’s direct not diffused. Closer light sources illuminate the subject more evenly. 
Annie libwitz - photographer that can create even light sources. She uses a massive light box. Fills and floating lights, Matthews lights. 
Light closer can create a really lovely contrast in the image. 
Shapes of light
Strips
Spots
Rings
Strings
Polarise makes light move through reflection. It takes reflection away, intensifying shadows and reduces highlights. 
Back lighting 
Rim lighting
Frontal
Side
Martin parr - super important photographer 
Shane meadows. 
Reflexive draws attention to the fact the camera was there.

Create a personal website with 1&1 →

A website I recently saw advertised was this one, it costs only £5 a month which is great however the actual website that you use to sign up looks hideous and put me off straight away. The graphic’s are hideous and hurt my eyes and the user interface took me so long to navigate i just gave up. So I don’t think based on that it’s an experience that I want my website viewers to experience so I’ll probably avoid using this one.

Squarespace.com is another hosting website that I’ve found however I don’t know I want to pay a monthly fee on top of paying for my domain. If money was no object I would use this company their website’s look really clear and professional and most importantly easy to navigate.

Here’s a still image of Khiew Jit Chun’s website I was talking about previously, as you can see the impact of the still images makes you want to continue searching the website and the easy navigation makes this easy and enjoyable to do. When looking at other artists that use flash website’s I was instantly put off by the slow navigation and crashing. This website is created through Wix which is a website software that’s free but does leave a lot of watermarks on your work which I’m not keen on but it’s definitely something I’m going to look into because the ease of navigation is such a pleasure to use.

#creative enterprise  #effectuation 

Here’s a summary of my research from class today on Effectuation.

What is effectuation?

- an idea with a sense of purpose (eg. wanting to make the world a better place)
- human problem solving (creating new things into the world)
- entrepreneurial expertise (common business logic to improve chances of success)
Context
- In the past successful entrepreneurs were placed down too a risk taking personality trait or that the entrepreneur took advance of a weak market or scientific break throughs. However neither theories have scientific evidence. 
image
causation = working towards a desired goal with a set amount of means
effectuation = evolving means to achieve new goals
Principles of effectuation 
- ‘Bird in hand principle’ - start with the means you have. don’t wait for a bank loan start with what’s readily available, who are you, who do you know.
- ‘Affordable loss principle’ - look at is the downside acceptable rather than is the activeness of the upside.
- ‘Lemonade principle’ - embrace changes as they come rather than sticking to one goal. If the market changes as unpredicted change must happen to keep the business alive.
- ‘Crazy quilt principle’ - form partnerships

Saras Sarasvathy, under the mentorship of Nobel Laureate Herbert Simon of Carnegie Mellon University, sought to provide “valid microfoundations for an economics in which Schumpeterian perspectives on innovation, competition, and growth are integral, yet consistent with recent evidence from evolutionary economics on the dynamics of markets and industries as well as with recent developments in behavioral economics on human decision-making.”

Artist Statement

Expresses who you are as an artist. Ultimately you are a student and that should be In it. A photograph of yourself is important in your about page. It’s good to have a face to go along with your work.

Show reels - best foot forwarded. Include your best work at the beginning. Breakdown of what you’ve done on each of the pieces in your showreel. 
Knower jit chun - example of a good showreel and artist statement
Sze jones - uses both wordpress and vimeo. Good example of length of show reel. 
On your website it’s a good idea to include breakdowns of things you’ve made. 
Don’t create your website in flash it limits your audience as certain devices can’t view it. 
Square space is a good place to create your website. 
When writing your cv you shouldn’t write using I, me or you. Use vimeo over YouTube it looks for professional. 
Blogs - show your passion in your the subject. 
Things I can include in my work
-photography
-video
-animation
-effects
-blog
Effectuation.org - join this website for this module - read the about page. And go through learn on each of the papers. Download all PDFs and take notes for next week.
