If I Direct the Camera on My Phone at a Bright Light, Will It Damage the Camera?

If I direct the camera on my phone at a bright light, will it damage the camera?

There are no manmade lights so strong that they will damage a camera. Only lasers have that kind of power, but then those can blind people as well.You can photograph a street lamp all night long if you want to.

parked highway patrol car flashes one bright light at me?

I hope that they were taking a photo. Speeders like you should not be on the road

Photographing microfiche readers: Bright light forces camera to darken image

This is a textbook example of image processing that we give the students as an assignment. You do a large mean-filter on the images and subtract it, and fix the contrast, maybe even threshold it.. I implemented it in Image View Plus More 2 as a standalone function called "Local Normalisation -> Remove Gradients e.g. from paper". I assume you have matlab and it is very easy to make a script in it with Io= imread, If=imfilter(Io,ones(100,100)), Ir=Io-If, and apply some scaling to If.

Which smartphone or tablet display does best in bright light?

Tired of squinting at your smartphone or tablet display on a bright sunny day? We may have the answer for you, then. DisplayMate Technologies president Dr. Raymond Soneira took a look at four tablets and four smartphones, gauging their performance in a wide range of lighting conditions from absolute darkness to indirect outdoor sunlight. Apple and Samsung's displays took top honors, with the iPhone 4, iPad 2, Samsung Galaxy S, and Tab 10.1 taking top honors. Doing much worse was Amazon's Kindle Fire, while the HTC Desire, Motorola Xoom and Droid X also fared poorly. Overall, it appears by a slight margin Samsung's displays are the best, while Dr. Soneira found the HTC Desire as the worst performer. Soneira's tests find that HTC has a lot of work to do on its displays. At a level of 20,000 lux, which is equivalent to full indirect outdoor sunlight, the display is unusable. Tablet-wise, the worst performer was the Kindle Fire, which shows similar readability problems at 20,000 lux and above. "Other than jacking up the screen Brightness, manufacturers have done very little to improve screen readability and picture quality under high ambient lighting," Dr. Soneira says. His company sells the software which he uses to judge the displays, which it says will also correct the problem. In other words? This guy has a vested financial interest in the results. Regardless, it's a good look into what electronics manufacturers still need to do to improve displays. We've heard a ton about Gorilla Glass, but in the end Corning was more focused on making thin, unbreakable glass than working on light reflectivity issues, where a lot of readability issues when it comes to ambient light come from. So that's not the answer either. Apple's made a lot of hay over its Retina display and its advantages. While it has done wonders for the readability and clarity of these displays, it's done jack for their readability in bright light - and DisplayMate has already said the display is not that great. Since we are becoming ever more dependent on these devices, this is a problem that begs for a fix. "While Apple and Samsung are currently the best performers in high ambient light, it is possible to do substantially better with advanced scientific lab tests and analysis", Soneira says. I doubt for one second that Apple will reach outside of its bubble in Cupertino for help, but you have to think they would be interested in Soneira's findings. Then again, they do say you get what you pay for, right?

How to achieve bright lighting without noise at night?

The lens and the camera qualities are an important factor. If you take this shot with a good lens and a high-end camera, there is no noise without any treatment.If you have to reduce quality on either piece, you will need to process the image for noise-removal (which probably happened here). There is no specific setting to watch for, except having the aperture all the way open. Otherwise, nearly every camera's 'automatic' settings will do what is possible

When should I turn my aquarium light on/off?

Fish need a dark period so they can rest. In the tropics, there's not a lot of variation in day lengths, so 10 to 14 hours of lighting is appropriate year-round. Actually, few fish prefer bright light, so the only real reason you need artificial lighting (in a room that has windows) is to grow plants. If you do not have live plants in the tank, you can just turn on the tank lights when you are in the room. (By the way, most fish do sleep. They just do not close their eyes, since they do not have eyelids.)
