Even though you cannot circumvent the laws of physics, there is one way to avoid diffraction in your photographs: use a larger aperture. If you need the absolute sharpest photograph, this is the only way to avoid the effects of diffraction. Are you photographing a scene that needs a large ...
Here is one fact you can derive from the postulate: Regardless of whether you are flying in an airplane or sitting on the couch, the speed of light would measure the same to you in both situations. The reason that is unexpected is because most physical objects that we deal with in the ...
When a total or annular solar eclipse occurs, observers outside the area covered by the moon's umbra (the inner shadow) will see a partial eclipse instead. During a hybrid solar eclipse observers will be able to see either an annular or total solar eclipse depending on where they are ...
Diffraction is a phenomenon that occurs when light passes through a very narrow slit. The individual photons behave like water waves passing through a narrow opening in a seawall. As the waves pass through the opening, they bend around the corners and spread out, and if you allow the waves ...
(because the barrier can stop the object). Now, although that’s how the world of classical mechanics works, these fairly straightforward situations become slightly wonky when we descend to the quantum realm. In simple terms, quantum tunneling refers to a phenomenon where an electron is able to...
Brown: Brown is a relatively low-contrast color that can blend in with many backgrounds, making it difficult to see in some situations. If you have placed a prism in the sun, then you have likely noticed the rainbow effect it produces. This is because white light is a mixture of all th...
Aperture is 1 of 3 factors that create an exposure so understanding aperture is a good way of getting to grips with taking an evenly exposed photo. There are also negative and creative effects of different apertures and this post will teach you what they
Unfortunately, while it is a good practice to keep the lens hood on and know that you can block off the light with your hand or another objects, shooting directly into the sun and including it in the image will render those efforts useless. For those situations, either change the perspectiv...
• Exposure occurs for the set duration (set shutter speed) • Rear curtain closes to end exposure • Rear curtain opens in order to return back to Live View With Silent Live View (Any Release Mode): • In Live View, so currently both curtains are open and mirror is up ...
In our theoretical model, the incident power (𝑃in) contributes to the focal plane irradiance distribution (𝐸fp) through two components: (a) the scatter/stray light component, 𝐸s, and (b) the diffraction component, 𝐸d, which are described in the following Section 2.3. 2.3. Estimati...
