If you're photographing a portrait and you want a shallow depth of field, set your aperture to f/2.8 and you'll often get a beautiful blurred background. 2.

Deze reflectoren moeten conform de lokale en internationale regelgeving zijn en vaak moeten ze een bepaald keurmerk hebben om te garanderen dat ze voldoen aan de veiligheidsnormen. In de Europese Unie moeten retroreflectoren bijvoorbeeld voldoen aan de ECE regulations.

In the world of vehicle lighting, the retroreflector plays an indispensable role. This component ensures that the light from, for example, headlights is directly reflected back to the driver. This significantly increases visibility and thus safety on the road. So, when you are driving your car and your headlights shine on another vehicle or object with a retroreflector, it sends the light right back to you. As a result, you see the other vehicle or object much better.

Neutral density filters, also known as ND filters, are essential tools for any photographer or videographer. They’re designed to reduce the amount of light entering the camera lens without affecting the color of the image. ND filters come in different strengths, and each strength reduces the light by a specific amount.The degree of light blocking is often referred to in terms of the number of ‘stops of light’ the filter blocks. For each ‘stop’ of light blocked, the exposure time doubles. An alternate terminology uses exponential values of the number ‘2’ to reflect this principle. Yet another system uses values of 0.3 to designate 1 stop of light blocking.For instance, an ND filter that blocks 2 stops of light can be called a ‘2 stop’ ND filter. Using the alternative terminology, it can also be called an ND4 filter (2^2 =4) or an ND 0.6 filter (0.3X2 =0.6). This terminology also applies to the strength of GND (graduated neutral density) filters.To choose the right strength of ND filter, you need to consider the lighting conditions and the effect you want to achieve. If you’re shooting in bright sunlight and want to achieve a shallow depth of field, you might need a higher-strength ND filter like ND8 or ND16. If you’re shooting waterfalls or other moving water, you might need a lower-strength ND filter like ND2 or ND4 to create a smooth, silky effect.Choosing the right strength of ND filter depends on the lighting conditions and the effect you’re trying to achieve. Here are the most common ND filter strengths and their corresponding light reduction:

In many European countries, retroreflectors are mandatory on certain types of vehicles. The specific requirements can vary depending on the type of vehicle, size, and usage. Typically, there are stricter requirements for heavier and larger vehicles like trucks and buses than for passenger cars. Generally, red retroreflectors are required at the rear of the vehicle, and white or amber ones at the front and sides.

Retroreflectors in vehicle lighting often use advanced materials such as glass or special plastics. These materials are developed to reflect light back to the source with high accuracy. The result? Significantly improved visibility and safety, especially in low light conditions such as at night or in bad weather.
