Look through the viewfinder of your camera aiming towards the scene you want to capture. Change your aperture as you look through the viewfinder and notice how the needle moves up and down.

If you are not using a tripod and holding your camera, always shoot at a shutter speed of 1/60 or more. This avoids blurriness in your photos from your hands naturally shaking from the pressure of engaging the shutter.

EUV lithography is considered better than conventional photolithography for certain aspects of chip manufacturing, particularly when it comes to miniaturisation and finer feature size.

Once you have decided on whether you want a large aperture or a small aperture (a large aperture will make the background of the image be blurry and a small aperture will make the background sharp), you can set your shutter speed to the number the needle is pointing to.

For high-volume chip production where cost and speed are crucial, deep ultraviolet (DUV) might still be preferred for some layers of the chip. However, for cutting-edge chips where maximising transistor density and performance is paramount, EUV becomes the necessary technology, especially for the most intricate layers of the circuit.

If you are taking a photo of a landscape, hold the meter out in front of the camera with the lumisphere facing the camera (the lumisphere is the round white blub at the top of your light meter).

Similar to a hand held light meter, a reflective meter will tell you what you should set your shutter speed to when you have your ISO and aperture set.

An incident light meter is hand-held and a separate device from your camera. It measures the amount of light falling on the subject or scene.

Light meters are used to get an accurate reading of the light conditions. Wherever you are taking pictures, either outside or inside, you can use a light meter to tell you at what level to set the aperture and shutter speed so you capture an evenly exposed image.

EUV is like a high-precision scalpel for creating the most delicate features, while DUV remains a versatile workhorse for general chip manufacturing. The choice often involves a trade-off between cost, performance, and feature size requirements.

Extreme ultraviolet (EUV) lithography is a cutting-edge technique to manufacture modern computer chips. It’s a type of photolithography, which utilises light to etch patterns onto silicon wafers, the foundation of integrated circuits (ICs).

Even though EUV Lithography is one of the most advanced techniques out there, it has its benefits and drawbacks to consider:

Hand held light meters can be expensive but luckily there are many apps that you can download for free that work just as well!

EUV lithography involves an interplay of light, engineering and material science. The following is a step-by-step breakdown of the process:

As you are holding out the light meter, press the button on the side of it and it should tell you what you need to set your shutter speed to in order to take an evenly exposed image.

If a light meter gives you a reading below 1/60 and you do not have a tripod, you will need to adjust your aperture to a lower f stop (the lens will dilate to let in more light) so your shutter speed can be set faster (to compensate for the extra light you are letting in) to avoid camera shake.

Your ISO should already be set based on the film you have inside your camera. Then, decide on whether you want a large aperture or a small aperture. A large aperture will make the background of the image be blurry and a small aperture will make the background sharp.

Tip: Some hand held light meters allow you to set the shutter speed and then you meter for a correct aperture. This is a better workflow to follow when you do not have a tripod and if there is not a lot of light where you are photographing.

Reflective light meters are usually built into your camera and they measure the amount of light that is being reflected off a subject or scene. Here is a photo of the light meter that you see when looking through the viewfinder of a Nikon FE.
