Did this interview with Martin Heck help shed light on the process? Let us know in the comments below. 3. What are some of your favorite places that you’ve filmed? What made these places special to you?There have been a lot of amazing locations I’ve visited in the past few years. Talking about New Zealand and Patagonia: These places are widely considered as the most beautiful places on earth. But last year I had the chance to shoot in a glow-worm cave system in New Zealand. It’s was really a tough but incredible experience. Being in a cave for 36 hours, lit only by glow-worms and in absolute silence, really gives a feeling of being on another planet.Other amazing places are Fjordland (NZ), Torres-del-Paine (Chile), Fitz-Roy-nationalpark (Argentina) and the Dolimites in South Tyrol.Then there is of course the eruption of the Calbuco volcano in Chile in late April of this year. That was the most jaw-dropping thing I’ve ever experienced. It’s hard to describe but when you feel and hear the deep rumbling from 30KM (18 Miles) away it makes you feel very small.4. What techniques and advice could you give someone that is looking to get into timelapse photography. Are there things they should avoid?I always say timelapse is the art of predicting the future. Make sure you know as much as possible about your location before shooting. It is easy to get lost in the technical details, but avoid dealing too much with what gear to buy and so on. It’s really a thing of learning by doing. If you make mistakes you learn from it and will never do them again. I still learn things today that I never thought could have happen.When starting out keep everything simple. A tripod and a camera. Static exposure. Then you slowly get into more advanced techniques like exposure-ramping and motion control. Make sure you don’t underestimate the factor of post-processing. Always go for highest-quality route even if it takes much more effort. We spoke with filmmaker Martin Heck and asked him a few questions about the process of creating amazing timelapse videos. Here’s what he said.Images from Martin HeckIf you aren’t familiar with Martin Heck and his production company Timestorm Films, you soon will be. Martin is a freelance timelapse photographer from Germany who travels the world looking for that one composition. His work is stunningly beautiful and crisp, which doesn’t come from an ARRI or a RED but rather a Canon 6D and Sony A7S. We were lucky enough to catch Martin between productions and got his insight on how he creates these works of art.1. First and foremost, what made you want to get into time-lapse photography, and was this something that you were always interested in?My interest in timelapse-photography basically started with a very old 0.3mp webcam I found in our basement and discovered a basic intervalometer setting in the software. This was in 2008 when I was 15. In this time, timelapse wasn’t that common as it is today and really got my full attention as it was very cool for me to see all the time compressed in a little 15s video.Purchasing better cameras and figuring out how to edit those timelapses really taught me everything I know today. I began building my own motion-control equipment and shot timelapses every time I was on vacation.With the first inquiries for my stock footage coming in 2010 I began to realize that there might be a market for timelapse and I was slowly able to get into higher end tech from this income.Now I am a freelance timelapse photographer, shooting 8K and traveling the world for those shots.So to conclude this question: Time-lapse really was the reason to buy my very first camera. So I would say this was something I was always interested in.2. What is your process like for finding the right timelapse subject or space?I pick spots from seeing photos on the internet, Google Maps, or places I have been before but wasn’t able to timelapse them. The next thing I do is check the environmental situation over time: Where and at which time does the sun rise/set. Same thing for the moon rise/set. What the moon-phase is and where does the milkyway rise and set. Sometimes I check if there are nearby roads were headlights from passing cars can ruin the shot.Then there are weather conditions to be observed. When doing trips to foreign countries, I also consider which season is the best to capture the kind of shots I’m looking for. Even the the humidity sometimes plays an important role as it could condensate on the lens.Those are a lot of factors going into the decision of finding the right location and time. When on location I always try to frame my shots in the most interesting way possible, while keeping it “clean.” Meaning that if there is one thing in the scene I don’t like (sometimes a fence, a sign, lights, buildings etc.) I will move my camera until it’s right. I always ask myself how and why I do something. I also don’t like to use a slider every time just because I can. Often there’s no reason to have a moving camera, in fact keeping the camera still can make for some pretty epic shots. 7. How many cameras do you use to get the shots you’re after?In Patagonia we mostly used all of our three cameras we had with us. But, when hiking, I have to limit myself to what I can carry. Which is mostly two cameras, three lenses, slider and tripod.8. To get the smooth fluid motion in your shot,s do you use the eMotimo TB3 alone? Is there other gear?Beside the TB3, I customized my Dynamic Perception Stage One slider with very lightweight carbon rods and shaved of some weight to make it more backpacking-friendly. 5. What tools are in your toolbox? What does it take to get the amazing shots that you’re able to capture?I currently own a Canon 6D and Sony A7s. Those are my main workhorses, together with a bunch of lenses from Canon and Samyang. For motion control, I use an eMotimo TB3 Black and a customized Dynamic Perception Stage One slider.On our latest trip to Patagonia, I shot with the Pentax 645Z medium-format camera (25mm, 55mm and 120mm Pentax lenses) to get 8K resolution.That’s my “toolbox” and it helps to get the best quality possible, but it is far from mandatory for doing timelapses. I still shoot sometimes with my old Canon 550D/T2i. Still does a perfect job.But most important, in my opinion, is being dedicated about what you do. If you get up every 2 hours in the middle of the night when it’s 2°C to check if it’s started to rain or if condensation is building on the camera, you really know why you’re doing this. Those shots are most rewarding. It’s hard to get those shots and that can been seen in the footage.6. Could you give us a rundown of the your favorite cameras to use? Also, what have you used in the past?Currently, without doubt it’s the Pentax 645Z. With 51MP and an outstanding dynamic range, it’s a very powerful camera. It’s an expensive camera (That’s why I don’t own one) but clearly the best I’ve used so far. Besides this, I use a Canon 6D and Sony A7s. From the beginning, I used a Lumix TZ3, TZ7 and Canon 550D. New cameras appear almost on a daily basis these days, so my kit will change over the time.last_img read more

The Secret To The Rams Blocking Success Isnt The Linemen Its Sean

Returning to Los Angeles, the Rams used the 11 personnel more than any other team in the NFL in 2018. So it’s possible that instead of the Rams being generationally superior at run blocking — or instead of Gurley being a one-of-a-kind game-altering running back — the Rams’ offensive line just faced fewer crowded fronts than other teams. This would at least provide some context for their overwhelming success — and help explain how Anderson could Wally Pipp an MVP candidate in the playoffs.To find out, I created a reasonable facsimile of Football Outsiders’ adjusted line yards and then calculated the number of yards each team earned either over or under expected based on the number of men in the box and the field position from which the play originated.6I removed QB scrambles but left WR run plays in. I also did not adjust for shotgun. Finally, I did not scale the adjusted line yards metric so that it looks like running back yards per carry. My version of adjusted line yards will not agree exactly with Football Outsiders, but there still is a high degree of correlation. Each metric predicts the other at an r-squared of 0.68.Both Football Outsiders’ line yards and my version agree that the Rams had the best rushing offensive line unadjusted for box count. When we look at line yards over expected after accounting for box defenders, however, the Rams aren’t the best run-blocking offensive line ever. In fact, they’re not even in the top four since 2009. 18New England20093.062.720.364.43 *Box-adjusted line yards adjusts for number of defenders faced near the line of scrimmage.Source: ESPN Stats & Information Group But an NFL offense is not just at the mercy of the defense when it comes to running against stacked or light boxes. Play-callers actually have a large degree of control over how many defenders near the line of scrimmage they will have to face. When an offense trots out three or more wide receivers, the defense nearly always matches with an equal number of defensive backs, which limits the number of linebackers on the field and lightens up the box.Since the 2009 season, the number of rushing plays that faced six or fewer defenders in the box has skyrocketed. This is a reflection of an evolving offensive philosophy, not a defensive one. The increasing number of light boxes was a response to the massive shift by NFL offenses to the “11 personnel”: 1 running back, 1 tight end and — most importantly — three wide receivers. Over the course of the past decade, the 11 personnel became the most popular personnel package in the NFL. It’s now the base NFL offense. And nickel5Defenses with five defensive backs on the field. is the current base defense — a sea change from the previous decade when 3-4 and 4-3 defensive fronts were the norm. 2New England20103.322.730.604.82 10Washington20123.162.740.434.24 Teamseason538 adj. line yds538 box adj. line ydsbox adj. line yds over expectedfootball outsiders adj. line yds 8New England20173.082.650.445.05 One explanation is that the Los Angeles Rams offensive line is just very, very good, and Gurley has been reaping the rewards. But I think there’s another factor at work — one that has more to do with the head coach than with the players on the field.Some football observers have gone so far as to suggest that the Rams 2018 run-blocking unit might be the best in the history of the NFL. While offensive lines are perhaps the trickiest position to evaluate with data, there’s actual evidence for this scorching-hot take using a metric created by Football Outsiders called adjusted line yards. Adjusted line yards are calculated by looking at each running play and using a formula to attempt to assign the proper credit to the offensive line. The metric punishes blockers for losses on run plays, credits the hog mollies with half of the yardage on runs from 5 to 10 yards, and gives the line zero credit for any field position gained 11 yards beyond the line of scrimmage.2Football Outsiders also adjusts for plays from shotgun, down, distance and situation, and it removes any scrambles and handoffs to players who aren’t running backs. By this measure, the Rams are the best-performing line in at least the past 22 years, the period for which data is available.31996 to 2018.But one problem with adjusted line yards is that the metric doesn’t account for the number of defenders the offensive line has to face during any given play, which has huge implications for how effective a rush will be. Running the ball when there are seven or eight defenders near the line of scrimmage is much harder than running against six or fewer. If a team runs more of its plays against light fronts, we should expect it to have more success in general. We’d also expect the offensive line in particular to have an easier time opening holes against defensive fronts that have fewer, rather than more, defensive players near the line of scrimmage that they have to block.Looking at 10 years’ worth of data from ESPN’s Sports & Information Group,4For a total of 126,154 running plays. We excluded scrambles and any plays for which no defender data was given. that’s exactly what we find. If we split the field up into 10-yard chunks, there isn’t an area of the gridiron that exists where running against seven or more men in the box is easier than running against six or fewer. 13New England20183.042.650.415.03 11Baltimore20183.122.710.434.61 5Los Angeles20183.312.830.515.49 1San Francisco20123.192.570.634.50 3New Orleans20113.312.730.594.95 14Houston20103.012.610.414.52 7New Orleans20183.122.690.455.19 Todd Gurley began the 2018 season on fire, accumulating yards and scoring touchdowns at a historic pace. Despite missing the final two games of the season, the second-highest-paid running back in the NFL led the league in rushing touchdowns and finished fourth in yards from scrimmage. And yet, Gurley may start Super Bowl LIII as a backup. Since returning from injury, the Rams star has been outplayed by fill-in journeyman running back C.J. Anderson, who has more or less relegated Gurley to a change-of-pace role.How is this even possible? How can a player go from being the league’s premier running back to backing up a guy who was cut by the Denver Broncos in May, the Carolina Panthers in November and the Oakland Raiders in December? We’ve seen backup running backs fill in admirably before — when the Chiefs released star RB Kareem Hunt this season, Damien Williams was just as, if not more, productive1Williams averaged 114 yards from scrimmage and 1.6 TDs in regular-season games he started, while Hunt averaged 109 yards from scrimmage and 1.4 TDs. — but it’s hard to remember it happening to a back as seemingly indispensable as Gurley, let alone on a stage as big as the Rams are on now. 15Seattle20123.142.780.374.42 12Carolina20113.112.710.424.32 9New York20103.172.730.434.56 17Dallas20092.982.600.374.48 19Tennessee20163.052.700.364.63 16Kansas City20103.062.700.374.44 6Miami20093.012.550.474.44 4Jacksonville20103.202.620.594.63 The Rams have the fifth-best offensive line since 2009NFL offensive lines by two metrics for regular-season adjusted line yards, yards accounting for the number of defenders in the box and yards over expected based on defenders in the box, 2009-2018 In fact, if all you know about a running play in the NFL is the approximate field position of a team and the number of defenders near the line of scrimmage, you’re able to predict the leaguewide yards per carry with an extraordinarily high degree of accuracy: 96 percent of yards-per-carry totals are explained by the offense’s field position and the number of men the opponent has in the box. How many defenders are in the box is almost certainly the most important factor in determining rushing success in football, so it follows that we should try to account for it. The 2012 San Francisco 49ers — who were 5 yards from winning a Super Bowl under Jim Harbaugh and QB Colin Kaepernick — take the honor of fielding the best run-blocking offensive line since 2009. Thinking back on the number of big plays Frank Gore broke off against stacked boxes, the ranking certainly passes the smell test. The 2010 Jaguars offensive line, ranking just ahead of the Rams, was also formidable: It opened massive holes for Maurice Jones-Drew and Rashad Jennings, who combined for nine touchdowns and 1,783 yards on the ground despite QB David Garrard doing nothing to scare opposing defenses away from crowding the line and trying to stop the run.The Rams still fielded the fifth best offensive line in our time frame and easily the best this year. But much of the credit for the success of the running game should probably go not to Gurley, Anderson or the Rams offensive line, but to Sean McVay. The second-year coach has put his players in the very best position to succeed through his scheme and play-calling. Running the ball out of the 11 personnel helps dictate to the defense and lightens the box for his linemen, allowing them to open holes even thrice-cut journeyman running backs can run through.While league observers can fall into the trap of over-weighting the effect of coaching, in some cases the credit and praise is warranted. The distribution of talent across teams is so even, it’s really not so much a matter of who you run the ball with — or behind — it’s a matter of when you run it. McVay chooses his spots as well as anyone in the NFL, and the Rams are in Super Bowl LIII because of it.Check out our latest NFL predictions. read more

US asks Myanmar to create conditions for sustainable Rohingya return

first_imgUS State Department. File PhotoThe United States has called on Myanmar to create the conditions that would allow for voluntary, safe, dignified, and sustainable returns of Rohingyas to their place of origin in Rakhine State, reports UNB.The US also commended the government of Bangladesh’s generosity in responding to this humanitarian crisis and appreciated its continued efforts to ensure assistance reaches the affected population, said the US Department of State in a media note on Friday.Earlier, the United States announced $60 million in humanitarian assistance at the launch of the 2019 UN Joint Response Plan for Bangladesh in Geneva.This funding will help address the emergency needs of more than 900,000 Rohingyas in Bangladesh, most of whom are Rohingya women and children from Myanmar, and the related needs of Bangladeshi host communities.The beneficiaries include Rohingyas who have taken refuge in Bangladesh since August 2017, when Myanmar security forces began committing atrocities, including ethnic cleansing, against Rohingya villagers across northern Rakhine State.The United States remains the leading contributor to the humanitarian response to this crisis in Myanmar and Bangladesh, having provided nearly $449 million since the outbreak of violence in August 2017, of which nearly $406 million is for programmes inside Bangladesh.”We continue to call on others to join us in contributing to this humanitarian response,” the media note reads.US assistance provides protection, emergency shelter, food, water, sanitation, health care, psychosocial support, and education for people affected by the crisis, including Bangladeshi host communities and people displaced inside Myanmar and in the region.US assistance also supports the efforts of humanitarian organisations and the government of Bangladesh to improve camp infrastructure and shelter ahead of the monsoon and cyclone seasons.last_img read more

A type of semitransparent polymer that can be mended at room temperature

first_imgCredit: Yu Yanagisawa A small team of researchers at the University of Tokyo has created a polymer that can be repaired when broken into two parts by applying a small amount of pressure at room temperature. In their paper published in the journal Science, the group describes how they came upon the polymer, how it was made, and how well it can be repaired. Materials may lead to self-healing smartphones This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Explore further Journal information: Science The researchers report that to test the material, they cut a small tile into to two pieces, then pressed the two pieces together into the original configuration using just a small force at room temperature. After 30 seconds, they further report, the healed tile could support a 300-gram weight. They note that pressing the material for longer amounts of times allows for even stronger bonds to form—eventually, after a couple of hours, the material reaches the same degree of bonding as it had prior to being cut or broken.More work will have to be done with the material before it can be used in a smartphone screen, however, such as making it more transparent. More information: Yu Yanagisawa et al. Mechanically robust, readily repairable polymers via tailored noncovalent cross-linking, Science (2017). DOI: 10.1126/science.aam7588AbstractExpanding the range of healable materials is an important challenge for sustainable societies. Noncrystalline, high molecular weight polymers generally form mechanically robust materials, which, however, are difficult to repair once they are fractured. This is because their polymer chains are heavily entangled and diffuse too sluggishly to unite fractured surfaces within reasonable timescales. Here, we report that low molecular weight polymers, when cross-linked by dense hydrogen bonds, give mechanically robust yet readily repairable materials, despite their extremely slow diffusion dynamics. A key was to utilize thiourea, which anomalously forms a zigzag hydrogen-bonded array that does not induce unfavorable crystallization. Another key was to incorporate a structural element for activating the exchange of hydrogen-bonded pairs, which enables the fractured portions to rejoin readily upon compression. Engineers around the world have been working hard to find a type of glass or plastic that can be healed easily when broken to address the problem of broken screens on phones and other portable devices. While some progress has been made, there still exists a need for something better. In this new effort, the researchers report on a new type of plastic that can be healed by simply pressing the broken pieces back together.As the researchers describe it, a team member was investigating glue properties with polymers when they discovered that one of the polymers under study could mend itself just by pushing the pieces together. Intrigued, the group looked closer. They found that the hydrogen bonds in the polymer formed in a way that did not crystallize, allowing the molecular chains to move freely. This allowed the bonds to re-form easily under just a small amount of pressure. After working with several configurations, the team settled on a polymer called polyether-thioureas (TUEG3)—it offered the best healing properties of those tested.
