How To Make Something Transparent In Photoshop?

How To Make Something Transparent In Photoshop
Adjusting layer opacity –

  1. Select the desired layer, then click the Opacity drop-down arrow at the top of the Layers panel.
  2. Click and drag the slider to adjust the opacity. You’ll see the layer opacity change in the document window as you move the slider. If you set the opacity to 0%, the layer will become completely transparent, or invisible.

Can you make an object transparent?

Make part of a picture transparent – You can make one color in a picture transparent to hide part of the picture or create a layered effect. Transparent areas in pictures are the same color as the paper on which they are printed. In an electronic display, such as a web page, transparent areas are the same color as the background.

Select the picture for which you want to change the transparency of a color. On the Picture Format tab, select Color, and then select Set Transparent Color, Click the color in the picture or image that you want to make transparent. Note: You can’t make more than one color in a picture transparent. Areas that appear to be a single color (for example, blue sky) might actually be made up of a range of subtle color variations. Therefore, the color that you select might appear in only a small area, and it might be difficult to see the transparent effect in certain pictures.

We’re sorry, but making a picture transparent is not supported in Microsoft 365 for the web. You need a desktop version of Office (on either Windows or macOS) instead.

How can a clear object be transparent?

Objects are either; transparent, translucent, or opaque depending on the amount of light that is able to pass through them. Objects that are transparent look clear, like eye glasses or water. Light passes through transparent objects, so you can see through them.

Can you make an opaque object transparent?

Light-matter interaction can turn opaque materials transparent by Lisa Zyga, Phys.org How To Make Something Transparent In Photoshop Illustration of a thin, dense vapor of quantum emitters (blue disk) interacting with an incident electromagnetic field. Physicists have shown that strong dipole-dipole interactions in the quantum emitters can be used to manipulate the light scattering and turn opaque objects transparent.

  3. By manipulating the light scattering, scientists can control the wavelengths at which light is transmitted and reflected by objects, changing their appearance.

In a new study published in Physical Review Letters, researchers have developed a new method for manipulating, They theoretically show how to induce in otherwise opaque materials using the complex dipole-dipole interactions present in a large number of interacting quantum emitters, such as atoms or molecules.

This ability could have several potential, such as producing slow or stopped light, along with applications in the field of attosecond physics. “The significance of our work is in the discovery of a very neat phenomenon (dipole-induced electromagnetic transparency ), which may be used to control light propagation in optically active media,” coauthor Eric Charron, Professor at the University of Paris-Sud in Orsay, France, told Phys.org,

“We showed how light scattering by a nanometric size system, collectively responding through strongly coupled two-level atoms/molecules, can be manipulated by altering the material parameters: an otherwise opaque medium can be rendered transparent at any given frequency, by adequately adjusting the relative densities of the atoms/molecules composing it.” As the scientists explain, light scattering is very well understood when dealing with individual quantum emitters; that is, single atoms or molecules.

  1. But the physics becomes much more complex when dealing with two or more interacting emitters.
  2. In this case, the electromagnetic field experienced by an emitter depends not only on the light beam striking its surface, but also on all of the electromagnetic fields radiated by all of its neighbors, which in turn are affected by the emitter in question.

Each quantum emitter can have a dipole, meaning a positive side and a negative side, due to an uneven distribution of electrons within the emitter. In a dense “vapor” of many quantum emitters, strong dipole-dipole couplings can then occur. The collective effects usually result in an enhancement of the light-matter interaction, although a very complicated one.

  1. Here, the researchers have theoretically shown that strong dipole-dipole interactions in a dense vapor of quantum emitters can be used to manipulate the spectral properties of the light scattered by the emitters.
  2. In particular, the medium may become transparent at a particular frequency that can be controlled to a certain extent.

The scientists explain that, on the most basic level, DIET results from destructive interference between the electromagnetic waves emitted by the quantum emitters. DIET is also closely related to another phenomenon, called electromagnetically-induced transparency (EIT).

EIT is also based on destructive interference, but it is induced by a laser instead of dipole-dipole interactions. The scientists expect that DIET could have many of the same applications as EIT, which include the generation of slow light or stopped light by interactions with the medium. Slow light has a variety of optical applications, including information transmission, switches, and high-resolution spectrometers.

Also, in the field of attosecond physics, DIET could potentially be used to generate high harmonics in dense atomic or molecular gases. The researchers anticipate that DIET can be experimentally implemented in a few different ways, including in atomic vapor confined in a cell as well as in ultracold dense atomic clouds.

However, both systems still face challenges for demonstrating DIET, which must be addressed in the future. “Currently our goal is to hunt for the observation of DIET in multilevel atomic or molecular systems,” Charron said. “Each emitter will behave as a series of oscillating dipoles, and this is expected to yield a series of transparency windows, thus opening the way for more elaborate and flexible manipulation strategies.

We will publish new results on this topic in Arxiv in the next few weeks. Moreover, DIET offers yet another way to slow the light due to strong anomalous dispersion. We thus plan to develop the study of slow light with DIET in the near future, with potential applications for information processing.” More information: Raiju Puthumpally-Joseph, et al.

How can clear object be transparent and visible?

A clear object can be both transparent and visible at the same time because although the majority of light passes through the object because of refraction, some of the light is still reflected back by the object, which makes it visible.

How do I make a non transparent PNG transparent?

Add a transparent area to a picture – If the picture does not have a transparent area, you can make one. You can create a transparent area in most pictures.

  1. Select the picture that you want to create transparent areas in.
  2. Click Picture Tools > Recolor > Set Transparent Color,
  3. In the picture, click the color you want to make transparent. Notes:
    • The Set Transparent Color option is available for bitmap pictures that don’t already have transparency information. It’s also available for some, but not all, clip art.
    • To create a transparent area in an animated GIF, use an animated GIF editing program, and then insert the file again.

    Change from transparent to opaque

  4. Select the picture.
  5. Press CTRL+T.
