A Guide to Cleaning Lenses and Camera Sensors

first_imgYou can’t keep your camera pristine and clean forever. Dust, dirt and smudges will speckle your camera from time to time. Here’s how you can clean your camera up and get back in the game.Cover image via ShutterstockWe’ve all been there (case in point). You’re out on a shoot and someone jumps in a rain puddle and it splashes your camera. You ask your friend to pass you a lens and they grab it by the glass leaving a huge smudge. Regardless of the circumstances, there will come a time where you will need to clean your lens to remove smudges or debris. Luckily, as long as nothing is scratched or shattered, there are plenty of tools and resources available to help you out. Here’s a few recommended methods.How to Clean LensesImage via ShutterstockLenses are very different instruments from your camera sensor. Lenses are exposed to the elements when shooting and are highly susceptible to getting dirtied up. The manufacturers also made them with this in mind, so working to clean lenses is a much different process than your sensor, which is meant to be protected at all times. The majority of lens dirtiness can be alleviated with some simple items that can (and should) be easily stored in your camera bag.Use Filters (UV or ND)Image via ShutterstockYour first preferred method for maintaining clean glass: protect your lenses with filters. Albeit, you’ll need to clean your filters just as often, but it will protect the actual lens from ever getting dirtied up. Depending on your shoot, you can use either an ND Filter (or GND if you’re fancy), or you can use a UV Filter for protection and slightly improved clarity.Lens Fluid and ClothImage via ShutterstockThe next preferred method (and first actual) would be to use a lens cloth combined with your camera-recommended lens cleaner. You can also use disposable lens tissues in lieu of the cloth, as long as its properties are comparable to microfiber. Residual oil remover fluids are available online or at your local camera store and can be purchased pretty cheaply.Lens WipesYou can also buy lens wipes (like these Zeiss Pre-Moistened Lens Cleaning Wipes) as they will be the most pristine in their individual packaging. They will also be the most expensive — so with budgeting in mind, it may or may not be a better choice than lens fluid and cloth.How to Clean SensorsImage via ShutterstockSensor cleaning is another story altogether. Damaging (or dirtying beyond simple repair) your sensor can be quite an investment depending on your camera. That being said, your camera manufacturers know this and the majority of cameras have built-in sensor cleaning mechanisms. The Canon 5D, for example, will auto-clean its sensor whenever you turn it off. Cameras auto-clean either by shaking/vibrating very slightly and quickly and/or negatively charging the air around the sensor to clean the dust off. If you do need to dive in, it’s best to try dry methods first before putting any foreign substances or pressures on the sensor.BlowersImage via ShutterstockBlowers are the recommended way of cleaning a sensor at first. Using a blower, not blowing with your mouth, is preferred, as you’ll want the air to be clear of liquid or anything else you may have in your breath. Would not recommend using compressed air either, as those can have propellents and lubricants that could mess up your sensor.BrushesImage via ShutterstockThe next step in the line of sensor cleaning succession would be to try using a brush to (ever so) lightly remove any dust or dirt off of the sensor. Make sure you use a clean sensor-designed brush that doesn’t have any hard hair that might scratch or do any damage to the sensor.Sensor Cleaning SwabsYou can also use sensor cleaning swabs. Like the lens wipes, the swabs usually come individually packed which will add up in cost in the long run — but for the higher price point, you do get the best results. The swabs take only one or two drops of solution and each side is used in one smooth, soft stroke across the sensor. You can watch this video for a better demonstration.Check Your Sensor and Lenses With a Reference PhotoThe ultimate way to see if your sensor and lenses are clear after cleaning is to take a reference photo. Set your camera to a low aperture like f/22 and take a photo against a pure white background. You can move your camera slightly to create a blur so that specks stand out. You can check it through your viewfinder or upload it and blow it up on a computer screen to check for any dirt or dust.Once you’ve checked your work through a clean reference photo, your job is done. The majority of these cleaning tools can fit quite easily and lightly in your bag. Just imagine — you may never have to do a shirt wipe again.Have any other tips or tricks for cleaning your lenses and sensors? Let us know in the comments below!last_img read more

Dwight Howard I Grew From Trade Rumor Experience

Dwight Howard‘s became NBA bad guy No. 1 after last season’s incessant complaining about his situation, where he would be traded to, his coach and just about anything else. Out of it came the nickname “Dwightmare.”Looking back on it now as a Los Angeles Laker, Howard said the whole protracted, tried saga made him stronger.“I think there’s a reason why everything happened the way it happened,” said Howard, who ended up traded to the Los Angeles Lakers. “So far it’s been an unbelievable experience for me. It’s like a dream come true.”Howard endured a tumultuous final season with the Orlando Magic in 2011-12. The three-time defensive player of the year demanded a trade to the Brooklyn  Nets at the beginning of the season, but the two sides couldn’t reach a deal.I did want to go to Brooklyn. That’s a place where I told the Magic that I really wanted to go,” to Stephen A. Smith and Ryan Ruocco on ESPN NewYork 98.7 FM. “[But] I was traded to the Lakers, and I think it was a blessing in disguise.“I thought I was going to get traded at the beginning of the year, actually; that’s when I asked for it. But everything happened for a reason. I had to go through last year to get to where I’m at today. It’s made me a stronger and better person for it. I had to go through the hell and the stormy forecast to come out to a place like this . . . and I’m thankful for it.”Going through it, however, was tumultuous. The perception was that Howard changed his mind about his loyalties every other day, fostering an impression of unsteadiness.“The whole year a lot of people were making up a lot of stories about ‘This deal is getting close, that deal is getting close to being done,’ or whatever, but none of those deals were ever close,” Howard said.Eventually, despite myriad trade rumors all the way up to the trade deadline, Howard stunningly agreed to waive his early-termination option and committed to stay with Orlando through the 2012-13 season.“I think a lot of it was people just felt like I was going back and forth with the whole thing,” Howard said. “But the business side, people don’t understand, when you’re doing business you have to be a shark. You have to demand things. If you don’t, people will run over you, and that was a lesson that I learned.“At the end of the day, you can’t please everybody. There’s gonna be people happy about me staying, there’s gonna be people happy about me leaving. I’m over that now. I can’t control the way how people feel about me.” read more

Almost 80pc Rohingyas want to go back

first_imgRohingya refugees walk on the muddy path after crossing the Bangladesh-Myanmar border in Teknaf. Reuters file photoMore than 90 per cent Rohingyas, who have taken shelter in Bangladesh, personally witnessed or directly experienced violence in Myanmar on or after 25 August, says a survey.The crackdown by Myanmar authorities since then led to a rapid mass migration of more than 647,000 Rohingya to enter Bangladesh, confirmed the “Rohingya Survey-2017” that documented the atrocities against Rohingya Muslims.However, 78 per cent of the Rohingya refugees surveyed said they would willingly return if the situation improves. About 16 per cent had no desire to return and only 6 per cent would return home unconditionally, the survey added.Xchange, an international organisation engaged in generating data to advocate better knowledge of human migration, conducted the survey based on interview with 1,360 ethnic Rohingyas between 15 September and 15 October in seven different refugee camps in Cox’s Bazar.The survey said the large number of respondents willing to return to Myanmar could, in part, be explained by the fact that there are very few opportunities for Rohingya refugees in Bangladesh.The survey pointed out that generations of Rohingya refugees staying in the camps following previous expulsions from Myanmar continue to live in poverty.Almost 100 per cent (96% to be accurate) respondents stated that the Myanmar military were the perpetrators of these abuses. Fifty one per cent reported that local ethnic Rakhine ‘extremists’ were involved.However, the involvement of ethnic Rakhine civilians was usually in a supportive role to the military, said the survey. “These civilians attacked Rohingyas, burned buildings, and committed other violent crimes that had the effect of driving Rohingyas away from their homes,” the survey added.last_img read more

How This CEO Went From 400 Different Passwords to Just One

first_img Register Now » August 28, 2014 4 min read When Heidi Ganahl founded the first Camp Bow Wow in Denver, Colorado in December of 2000, most people had never heard of doggie day care or upscale boarding. The concept took off more quickly than even she imagined, and she now has 122 franchises with 23 more locations in the pipeline across 40 states.Twenty-five employees (and their dogs) work in the Camp Bow Wow headquarters in Broomfield, Colorado along with 3,000 other employees in the franchises. Ganahl spends her days visiting franchises, managing five members of the leadership team, handling escalated issues and meeting with potential franchisees. All this with a husband, four kids and two dogs of her own. She juggles all this with the help of her smartphone and tablet. Here are three apps she can’t live without:1Password. Ganahl used to be an IT person’s nightmare. She stored all her 400 different passwords for both work and personal into a spreadsheet stored on her computer. And just in case a thief had trouble locating the information, she had helpfully titled the document “Heidi’s Passwords.” She realized the error of her ways last year when her laptop was lost for almost two weeks and panicked trying to change all of her passwords. Without the spreadsheet, she couldn’t remember them and constantly spent valuable time resetting passwords each time she forgot. After the laptop incident, an employee suggested she download 1Password, a solution which logs you into all of the sites and apps you have preprogrammed with just a tap of a single button once logged into the app. She says between not needing to reset passwords or hunt through her spreadsheet the tool saves her at least 30 minutes every day.Related: Travel Tech: 4 Gadgets for Running Your Business on the FlyMy Fitness Pal. Since Ganahl spends at least one week a month on the road for business, eating healthy and exercising regularly is a challenge. Last year nine of her friends who also travel for work formed a support group on the online platform, sharing workouts and diet successes as well as pointers for her sister travelers.  Before she joined her friends on My Fitness Pal she didn’t always fit in her daily workout and found herself eating at the same restaurants that she knew offered healthy food or grabbing less healthy options. But now, she knows that if she skips a workout she has to answer to her friends and they often share ideas for quick meals on the run. “Last week one of the group members posted about a healthy and yummy meal she had in the Chicago airport so next time I pass through on a layover, I am definitely going to eat there,” says GanahlRelated: How to Create a Super Strong Password (Infographic)Orbitz. Earlier this year Ganahl found herself stuck in Los Angeles airport due to flight delays at the same time her husband was leaving on his own out-of-town trip. If she didn’t make it home very soon, no one would be available to care for their 5 year-old and two-year old twins. Ganahl didn’t trek back to the ticket desk, but pulled up the Orbitz app and bought a cheap one-way ticket on another airline that would get her home in time. While she’s used other travel apps, she returns to Orbitz because it saves all of her frequent flier numbers and remembers that she likes to sit by the window so she can look at the landscape. Ganahl estimates that the app saves 20 percent of her time when booking tickets for herself and friends and family.  “Orbitz even remembers that I like to connect through the Minneapolis airport since it’s such a fun spot to hang out.”Related: Wake Up and Kick-Start Your Mornings With These 5 Bright Apps Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.
