This feature can be more visibly pronounced at night. We can use neon signs and light bulbs to create wonderfully defined round shapes. Any kind of small bulb will be the best motif for your subject's background. The wider open your lens is, the more pronounced the effect will be, since the convergence of the light is not guided through a small aperture that would help the light to be channeled.

Playing with spherical aberration, we can control the effects by over-correcting or minimally correcting the distortion. On one side, there is what is called a soap bubble bokeh look. Where it shows this effect, the aberration is over-corrected. On the other side of the spectrum, with minimal correction, the lens will render a soft focus glow across the frame.

Last time we spoke with Lou Guarneri was back in 2022, so we knew that the launch of our Nour Triplet V 2.0/64 Bokeh Control Art Lens on Kickstarter was the perfect opportunity to catch up with him while collaborating with our latest lens.

Not all light rays are created equal. Blue rays will have different wavelengths to red rays. Since all transparent materials are dispersive, the index of refraction increases as you move towards the blue spectrum of light.

We worked to give photographers the beauty of the triplet lens system, and the versatility of bokeh control. When placed in the center, this lens is able to provide a correct image, thus allowing a clean, classic look to cover every possible scenario when telling a story.

On the other side of spherical aberration control is the under-correction result that leaves light rays scattered and not converging toward the center. The sharpness at the edges of our objects and subjects is the first quality altered. This effect invokes the feeling of softness.

While most of us have heard of super resolution microscopy, many of you may not have heard of MSIM, or Multifocal Structured Illumination Microscopy. This under-the-radar imaging technique is relatively quick, cheap (by comparison) and will allow you to get a lot of data, fast. So What is MSIM Anyway? MSIM, as I mentioned earlier,…

Shooting days are tough. Many decisions are looming over your head when it comes to conveying a feeling, a mood, or making a point through your storytelling. Using the right tool makes a difference in achieving a perfect result. With the needs of creators in mind, we have designed the Nour Triplet V 2.0/64 Bokeh Control Art Lens. With this lens there is no more worrying about your choices, the right lens is the one that gives you more in one twist.

Spherical aberration occurs because spherical surfaces are not the most functional shapes to make a lens. Nonetheless they are the simplest shape to which glass can be ground and polished, and therefore are often used. Spherical aberration causes beams parallel to, but distant from, the lens axis to be focused in a slightly different place than beams close to the axis. This manifests itself as a blurring of the image. And when over-corrected, this effect results in marked lines across the background of an image.

Interested in the detailed structure of your tissue? High-resolution imaging techniques, such as brain electron microscopy, provide an intricate view of your tissue. While it may be a rather complicated procedure with nasty chemicals, the advantages of epon embedding can make it the best choice for morphological studies. The hard blocks are excellent for structural…

There are also framing choices that allow bokeh effects to be clearly visible in a picture. For example, when the light coming behind a tree refracts, this creates a rich texture for the bokeh to be visible. Over-correcting the effect implies that the ray will pass over the center, ending up in the out-of-focus areas to look like a pencil has drawn a ring around your bokeh.

There are different types of aberrations which can affect the sharpness, focus, magnification, distortion, and color of an image. Our lens has a triplet structure as its core design. This simple structure can correct most aberrations, however we have selected this formation and focused our new lens to operate with one in particular, spherical aberration.

When building a lens, one must consider aberrations that require corrections. These optical imperfections in the glass react to the light in different ways, dispersing the rays. First discovered by Hasan Ibn al-Haytham, the law of refraction is the first step in understanding the aberrations that occurs when light enters an object. In short, it is the behavior of light passing through a transparent object that does not converge to a single point.

Photographer Bitdam takes us on a journey with the Nour Triplet V 2.0/64 Bokeh Control Art Lens, capturing scenes that resemble a blur of memories that fade over time.

Blue light passing through a transparent prism will bend or refract more than the same red light part of the ray. The result is what is known as chromatic aberration. The falling position of the ray will affect our distortion, it is therefore with the insertion of the negative part (a concave lens) that chromatic aberration can be corrected.

The Nour Triplet V 2.0/64 Bokeh Control Art Lens features a spherical aberration control knob that allows you to move from right to left through the center of the lens, and get three different looks in one. So how is this possible?

Have you ever been shown how to use a microscope properly?

The soft focus effect will express a delicate feeling of charm and mystery. This feature is immediately visible throughout the image, and as soon as you frame the scene, you will see the results. The image will be in focus but that the diffusion effect of the scattering light gives a sublime and delicate aura to the picture.

The study of geometric probability in stereology may seem like a large, overwhelming area of focus but, don’t panic, it’s not!
