A lot of people constantly wonder how photographers are able to capture clear images of bursting balloons, water splashes and so on. The primary objective of high-speed photography is to capture objects when they’re in motion. You can easily capture events which follow a very predictable sequence. In every case, you should be able to detect a specific trigger, wait for the even to occur and take a picture.For instance, if you want to capture a drop of water hitting the surface, you need to detect the precise time when the drop of water starts falling. The next step is to create a basic delay between the event and trigger. Last but not the least, you take a picture. There are two different methods of taking pictures via high-speed photography. In the first method, you use the shutter of a camera, and the other requires you to use an electronic flash.1) Shutter MethodThe shutter method offers a major advantage. It allows you to enjoy high-speed photography outdoors. You will also be able to completely illuminate the subject and its background. Since the shutter can be used to freeze the motion of your subject, it offers limited speed. Usually, the maximum speed of a shutter ranges between 1/4000 seconds to 1/8000 seconds. Thus, in some cases, fast moving objects may seem blurred.In addition to this, there is also a basic delay between the actual exposure and shutter release. Depending on the type of camera, it can even be close to 100 milliseconds. Moreover, you could also experience basic variation in timing. Therefore, if you require high timing accuracy, you should not use this method.2) Flash MethodThis is the second method of high-speed photography. You can take the picture by simply opening the shutter of your camera, activating the electronic flash, and closing the shutter. However, you need to take the picture in a dark room. Since the room is dark, long exposure will not have a major effect on the final output. Flash light duration will become the actual time of exposure.Better timing consistency and exposure speed are the primary advantages of the flash method. Electronic flashes can offer speed of 1/10,000 seconds or faster. If you lower the power of the flash, the flash duration will be shorter.The lag between the flash strobe and trigger will be insignificant. However, there’s also a major disadvantage of this high-speed photography method. You can just use this method in a dark room. Moreover, it can also be difficult to offer uniform lighting or illuminate the background properly.

Does Your College Understand What Students Want And Need From Them?
It must become clear to every college leader that college students want and need good jobs when they graduate. In today’s job market, colleges that do not do everything possible to help students achieve that goal are failing their students.Students no longer attend college simply to obtain a good education. Those days are long gone. Today, students are going to college so they can land a good job, earn a good living and build a future for themselves and their families.Of course, college has always been expensive. However, today, with college loan debt outstripping credit card debt, students need a good paying job so they can live on their own and pay back their loans. When students are not able to land a job that pays well, they are usually forced to live at home with their parents and either defer their loan(s) which adds interest or put nearly everything they earn into their monthly loan payments. That is not a great way to live.Colleges may tell you that their job is to provide students with a good education. That is true but not totally correct. Their job is to serve the needs of their students. When landing a good job is a top priority for students, colleges must respond by making that need one of their top priorities. It does not make any sense to send well educated graduates out into the job market when they are unprepared to compete for the good paying jobs.All students need colleges to help them:- Learn how to conduct an effective job search
- Find out exactly what their target employers expect of them
- Create and follow a semester-by-semester employment plan
- Perform the activities and obtain the practical experiences that employers want
- Build a list of impressive accomplishments
- Identify employers with appropriate employment opportunities
- Learn how to build a network
- Develop an impressive resumé
- Practice their interview strategies
- Cultivate references… and much moreWithout substantial, ongoing job search preparation assistance throughout their entire college experience, too many good students will fall short of their employment goals. That means that their careers will get off on the wrong foot and they will have trouble paying back their college loans. That is not the way students and their parents want things to work out.When colleges show concern for the job search preparation needs of their students, they shift priorities, change the way they operate and provide the resources needed to address those needs. However, when colleges do not respond to important and legitimate student needs, they are sending a clear message that they do not care about those needs.Most colleges will tell you that their career services offices are doing everything possible to help their students prepare for their job search. However, colleges know perfectly well that their career services staff reaches only a small percentage of students in a given year and very few of those students will be fully prepared to conduct and effective job search. By using their current job search preparation systems, no college can thoroughly serve and prepare 100% of their students. To do that properly, things have to change.I can assure you that students do not enjoy entering the job market and trying to compete for the most attractive jobs knowing that they are unprepared. Fortunately, progressive and responsive colleges have begun to seek out and implement systems like The Job Identification Machine™ and The Job Search Preparation System™ because those systems will effectively serve and prepare nearly 100% of the students at their colleges.Does your college understand what students and parents want and need from them? Maybe not. If every student does not receive the full and comprehensive job search preparation assistance that they will need to land a desirable job in their own field of interest, there is much more that your college can do.
