The choice of colour temperature should consider the intended purpose of the space and the desired mood. It's important to note that colour temperature can influence the perception of colours in the environment. Warm white light tends to enhance warm colours like reds and yellows, while cool white light can make colours appear more vibrant and cooler tones, such as blues and greens, more pronounced.

Illumination plays a crucial role in creating a visually comfortable environment by providing appropriate lighting levels, minimising glare, and ensuring visual clarity. Here's how illumination contributes to visual comfort:

This is intriguing, on a whole host of levels. I love the idea of not having to wait to find a copy of a printed pattern in my size, or stalking the mailbox to see if arrive after I order it online. I love the idea of skipping all the paper of printing a PDF pattern. I love the idea of skipping tiling small pages together when printing on my own printer, if I want to have it NOW rather than waiting until the large-format printer can make me a copy. I love the idea of skipping tracing the pattern size I need from those pages. I love the idea of not needing to STORE those pattern pages.

Look for bulbs that are around 2800 Kelvin. The scale is indicated by the color of iron at different temperatures on the Kelvin scale.

You can read a much more in-depth explanation in this excellent post from Craftstorming and from Patterns for Pirates. You can also visit Projector Sewing, which has an extensive resource list, or Craft Industry Alliance, where the pros and cons are more fully addressed. Some pattern companies, like Simple Life, include free downloadable files to test out!

These recommendations serve as general guidelines, and it is important to consider factors such as visual tasks, age of occupants, specific activities, and the nature of the environment when determining the appropriate illumination levels. It is also worth noting that lighting should be uniform, without excessive glare or shadows, and take into account any applicable local or industry-specific regulations or standards.

When I received the VANKYO 470 projector, I also received a ceiling mount. The VANKYO is a portable projector, which means it can be set up in a backyard on a bedsheet for summer movie night, or (because it has an admirable resolution) as a home projector for movies and TV. It’s also a well-reviewed and recommended model for sewing pattern projection.

These two units, lux and foot-candle, are widely used to express the level of illumination in various applications, including indoor lighting and outdoor lighting, workplaces, architectural lighting, and more.

Colour temperature refers to the characteristic colour appearance of light sources, specifically how "warm" or "cool" they appear. It is measured in Kelvin (K) and describes the colour of light emitted by a source when it is heated to a particular temperature. The impact of colour temperature on the perception of illumination is significant and can influence the ambiance, visual comfort, and the way objects and spaces appear. Here's how colour temperature affects the perception of illumination:

Let me know what you think: does a projected sewing pattern sound like a headache? A much-needed advancement? As if we’re living in the year 3000?? Leave a comment below, I’d love to have your commiseration as I commence experimentation!

I didn’t read these sites before I jumped in with both feet, quite frankly because I was convinced I would start installing the projector only to discover some kind of road block that meant we’d hit a wall and could go no further. Ironically, installing the project was SO EASY! Since it’s also an essential step before testing out the various programs and techniques to make crafting or sewing with a projected pattern work, it’s the focus of the video below.

Illumination can be measured in different lighting systems using various instruments and techniques. Here are some commonly used methods for measuring illumination:

I’m not an expert with a drill, by any means. My husband was out of town, my kids were away at summer camp, and I was alone in the house past 9 pm when I decided IT’S TIME and installed the projector above my sewing table. AND IT STILL WORKED!! IN UNDER 30 MINUTES!!

It is important to consider these factors during the design, installation, and maintenance of lighting systems to achieve appropriate and effective illumination levels in various spaces, taking into account functionality, visual comfort, and energy efficiency.

It is important to note that while these units provide a standardised way to measure and quantify illumination, the specific lighting requirements and recommendations may vary depending on the application, industry standards, and local regulations.

See, the catch to projector sewing is that in order for this idea to work, the projector must be installed on a surface that allows it to use the cutting table as a “screen.” That requires suspending the projector using a down rod similar to a ceiling fan, so that the projected image isn’t distorted and instead displays flat at a set scale.

I have just completed reading your article. It was an exceptionally well-written article. Looking forward to reading your next article. Thank you. Keep posting stuff like this!

The recommended illumination levels for different environments and tasks can vary depending on the specific requirements and activities conducted in those spaces. Lighting standards and guidelines provide general recommendations to ensure adequate lighting conditions. Here are some typical illumination level recommendations:

The colour temperature of light sources can have a significant impact on the ambiance and perception of a space. Colour temperature is measured in Kelvin (K) and describes the appearance of light emitted by a source, whether it appears warm, neutral, or cool. Here's how different colour temperatures can affect the ambiance:

By considering these factors and ensuring appropriate illumination levels, proper illumination design can significantly enhance visibility, reduce eye strain, and create comfortable and productive environments for various activities.

In simpler terms, illumination is an objective measurement of the amount of light present in a space or falling on a surface, whereas brightness is a subjective perception of how light or dark an object appears.

In some cases, a combination of different colour temperatures may be used within a space to create contrast or emphasise specific areas. For instance, a warm white light might be used in a lounge area to provide a relaxing atmosphere, while a cool white light could be utilised in a kitchen or workspace to enhance visibility and promote concentration.

Illumination levels vary depending on the application, such as residential, commercial, industrial, or outdoor lighting. Lighting professionals, designers, and engineers use lighting design calculations, lighting standards, and guidelines to determine the appropriate illumination levels for specific spaces and activities.

Check out my video on YouTube, with a time lapse of the entire–and I do mean the ENTIRE–process, including the part where I remember that drills need bits and leave the room to go get them, plus my “Closet Cam” recap after the fact:

I saw your video on YT and have been looking forward to your review on the use of it. It is such an interesting step forward for dealing with patterns especially storage issues! I have seen a few pattern companies recently adding in projector parts to their patterns (Jalie).

In the context of lighting, "illumination" refers to the process of lighting up an area or space with artificial light sources. It involves the distribution and intensity of light provided by lighting fixtures to enhance visibility, create a desired ambiance, and support specific activities within a space.
