DSLR, How to use DSLR camera

If you want to know how to control a DSLR camera in a simple way, the following is the instructions There are many modes in a camera to capture a good quality photo. you can capture a photo in auto and hope for the best, but if you want to do it profusely then you would be better off in manual mode. Rotate the dialer of the camera in manual mode and then you will see some options, some of which adjust light, blur, and motion, you can adjust it as you like. 1. Setting - shutter speed (ss) =  You always have to put its value above 125 for a still shot, but for a moving shot, you should try it for above 500. 2. Setting  - aperture = It is used for making blur in your image. When its values are set to low then the depth or blur looks higher and remember you should its value to low to get a nice look your picture. 3. Setting - you have to put its value according to your light in your frame. It's best to keep it under 400 when you are in bought daylight. When you have

Hantavirus

Hantavirus is not a new virus and has been infecting humans for decades. This is the news in a line. Reports of a person in China dying due to a virus called hantavirus have spread panic at a time when the world is battling the pandemic of the novel coronavirus. hantaviruses are a family of viruses spread mainly by rodents and can cause varied disease syndromes in people across the world. It is important to take note that unlike coronavirus, hantavirus does not spread from one person to another, but rather through touching rodent urine, dripping etc. and then touching your eyes, nose or mouth. Hence, humans who get infected with hantavirus usually come into contact with rodents that carry the virus. As per the CDC, rodent infestation in and around the home remains the primary risk for hantavirus exposure. This virus also spreads when virus-containing particles are stirred in the air and the infection occurs if you breathe in the virus particles present in the air. T

India Lockdown

India’s prime minister decreed a 21-day lockdown for the country India, the world’s second-most populous country, will order its 1.3 billion people to stay inside their homes for three weeks to try to curb the spread of the coronavirus, Prime Minister Narendra Modi declared on Tuesday. “There will be a total ban of coming out of your homes,” Mr Modi said. “The only option is social distancing, to remain away from each other,” he said. “There is no way out to escape from coronavirus besides this.” “Every district, every lane, every village will be under lockdown,” he said. “If you can’t handle these 21 days, this country will go back 21 years.” Source - Internet ( https://www.nytimes.com/2020/03/24/world/coronavirus-updates-maps.html#link-1854b568 ) This may be the subject of copyright

Sharper images of black hole

According to the new study, scientists have calculated and predicted an intricate internal structure within black hole images caused by extreme gravitational light bending. The study has been published in Science Advances. In this, the lead author Michael Johnson of the Center for Astrophysics Harvard and Smithsonian has described how the swirling ring of photons around a black hole could be the key to unlocking sharp photos. "The image of a black hole actually contains a nested series of rings," Johnson tells IFLScience. "Each successive ring has about the same diameter but becomes increasingly sharper because its light orbited the black hole more times before reaching the observer. With the current EHT image, we’ve caught just a glimpse of the full complexity that should emerge in the image of any black hole." By stacking images of a black hole’s “subrings,” we may one day be able to create a much sharper complete photo of what a black hole looks

Does planet 9 exist

Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the unusual clustering of orbits for a group of extreme trans-Neptunian objects, bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.   Wikipedia It is basically a planet that has not existed till now, it may be there or maybe not it is nor proven to be neither proven not to be.

Corona Vaccine

Here are three of the vaccine that are tested at the time Moderna's mRNA-1273 Moderna Inc. of Cambridge, Massachusetts, has already begun Phase I human testing of its mRNA-1273 at Kaiser Permanente Washington Health Research Institute in Seattle. The test has enrolled 45 healthy adults ages 18 to 55. Phase I will continue over the next six weeks. Phase I of testing looks at the vaccine's safety and whether it is producing an immune response. A later phase of research will look at whether the vaccine is effective in preventing infection. Inovio's INO-4800 Inovio Pharmaceuticals of Plymouth Meeting, Pennsylvania, is using an approach similar to Moderna's to develop a vaccine by modelling off the virus' sequence. Three hours after China published the sequence of the virus online, Inovio developed INO-4800. Inovio uses something called DNA medicine, which is made up of optimized DNA plasmids. Inovio has already developed a vaccine using this

Why should you buy MacBook

Have you ever noticed that any professional blogger, computer science worker or YouTuber or video editor you could say use a MacBook, Why do they don't use a Windows computer instead, it costs half the price of a MacBook with almost dame the performance well not the same, but almost the same? Here are some things which make the MacBook just better or not:- MacBook is very thin and lightweight and of course, it looks sick. The hardware and software are great so of course, its made by apple. Getting hacked have a less chance. Special software support like "Final cut pro" is only available in Mac OS. The always updated OS in it makes it less likely to get virus. It is used in coding because of its powerful hardware.        Remember you can not game on it. Final thoughts:- In build quality: definitely. In terms of being user friendly and usability: Depends on your needs. Overall I'd say yes they are superior. Ps: I don't use it for gaming

What is dark web?

                               What is the dark web? It is a website in which the illegal cases happen. it cants run in chrome browser but it can run in any third-party browser, like opera etc. the most dangerous cases happen in this web-like the red room or ghost tail.  RED ROOM - this is an illegal official web in which the people are kidnapped and they are tortured. like, a girl is in a room and she is facing torcher and the people are seeing her as joy. But there are some official cases happen on the dark web.  come let us know how we can run the dark web in safe  - always cover your webcam and mic before using the dark web. you can also use tape to cover your camera or mic. don't use the dark web more than five hours a day. if any portion of the dark web is demanding you to give your bank detail then don't give it. there are many people who shop on the dark web so always keep it in mind that you don't have to shop in the dark web. Don't use your

NASA Identifies Asteroid

NASA Identifies Asteroid 52768 (1998 OR2) as NEO NASA detected recently so massive that it could destroy our entire planet. The space agency’s tracking systems from the Center for Near-Earth Object Studies identified the space object, which has been dubbed 52768 (1998 OR2), speeding toward Earth at a velocity of approximately 31, 320km/h. If the giant asteroid keeps it up like this, it is supposed to approach Earth on April 29. According to scientists, we don’t have reasons to worry at all. They explained how the space object will only make a “close approach” and won’t enter our planet’s orbit. Asteroid 52768 (1998 OR2) measures almost 4.1 kilometres across and is categorized by the Planetary Society as a hazardous space object.

Drosophila

Drosophila is a genus of two-winged flies commonly known as fruit flies that are used in evolutionary and developmental studies. D. melanogaster is an important model organism for the study of genetics and development. Julien Royet, professor of Genetics from University of Marseilles, France, on Thursday said she was very impressed with some of the work happening in India around Drosophila, the common fruit fly which has been a model organism to address basic and applied questions in life sciences. The conference, being held for the first time in India has  given students exposure to showcase their ideas, which they have done with 300 posters on topics like immunity and memory, among others.
