What is HDR ?

HDR or High Dynamic Range is the process of making images that contain a large range of Dynamic Range , the range of difference between the " bright " and " dark " are very large , so-called dynamic exposure range .
HDR was formerly called HDRI ( High Dynamic Range Imaging ) . is one technique that involves basic knowledge of shooting techniques and advanced digital imaging . Essentially is to create a file photo ( format * . Hdr ) by combining several photos berobjek same " exact " but different eksposurenya . To produce a file photo a high dynamic range of values ​​( for the purposes of further if more extensive artistic variations )
State differences in darkness and light are very large such as this is called HDR and could be solved with the HDR process . If differences in darkness and light are not too big so instead of HDR lah . About HDR among others in :

Three Main Steps How to Make HDR Photos :
1 . Make Pictures with Multi - Exposure Bracketing different or the technique .
2 . Merge .
3 . Tone -Map

In brief are as follows :

1 . Multi - Exposure : Making some photos of the same but different exposure . ( Bracketing ) .
· There are at least 3 photos with different exposures
· Exposure is a measure of the brightness of a photo . Minus value means that the picture is getting darker , plus the value and the value 0 otherwise normal light )
· 3 photos to be taken it should have the exact same object , use a tripod , or place it on a flat surface without changing the position of 3 photos when shooting because it will later be combined into one photo . If the ordinary with DSLRnya dah ... it could be without a tripod .
2 . Merge : Combine the photos with photo processing sotware like Photoshop , Photo Matic , or Dynamic Photo HDR . ( Download Link Software is here )
All that will be easily filled with cameras Digital Single Lens Reflex ( D - SLR ) due to exposure settings can be done automatically with a continuous shot in Bracket mode ( a mode that shooting 3 or more images in a sequence with different exposures ) , or manually by setting exposure at shutter speeds vary . Remember not to change the aperture . And the tripod is very necessary to get a good result because we certainly do not want our object to shift from one photo to another is not ?
3 . Tone -Map : Perform Tone Map to the combined light of the dark to set the Tone , Tone many processing software , such as Photoshop . If using Dynamic Photo HDR easier in my opinion .
It is a three main steps to make HDR , which will be explained in more detail . Each time you want to make HDR photos , memorable, there are 3 main steps in the process HDR above :)
" Multi - Exposure " / " Merge " / " Tone -Map "
So if there is a state of nature or portraits or anything in the world that contains the difference of dark and light are very large ( large dynamic range ) you can create HDR photos on the circumstances . Does not always have to be during the day , evenings are also many circumstances that contains HDR .
Fake HDR ( Pseudo HDR ) : There is also a fake HDR , which perform Tone Folder to a single file that is processed into 3 different file exposure , but this is not a Fake HDR HDR or Pseudo HDR . The result was good and nyussss mak ... but sometimes it is not perfect because the first step is not performed previously ( MultiExposure ) .

When someone says " I CAN READ YOUR MIND " . What is in your mind ? What is the " wow , definitely heresy " or " this definitely help jin " ? BIG ONE turns you , if it is in your mind ! ! ! why ? Why? Emangnya no way to be able to read the mind without heresy - klenik'an ? Oooh , there must be , and I 'll try to explain it here , so listen completely what I've explained , you will learn , and you can practice it with pride ! ! ! you are not misreading , because it ' tekhnik mind reading ' can learn to read patterns in .

                Prior to further explain how to read the thoughts of others, I think you need to understand the system used to work mind ! ! ! why ? Because human behavior is influenced by his own mind . And for those of you who have never even thought of work to learn the system , you can read my article relating to it HERE

                Let us continue our discussion this time , that means reading the thoughts of others. Now let's assume you already understand the working system of mind , if not , you own one that did not study it, but I had permission is related article about it .

Well, as we already know, most human behavior firmly based than what he had in mind , so it is very clear , when you want to be able and know how to read minds , you simply look at the behavior of what appears from her attitude , if kerennya language Body Language . Sesimpel is it? Lho , If there's a simple way why should figure out how complicated , is not it?

                Basically you all are able to read the mind of others, for example , when your friend showed expression of grief , ( maybe ) you often ask your friend the " hey , what the heck pikirin lu ? Keliatannya excessively lethargic " , wow , without you knowing it , you have often read other people 's mind just by looking at the expression on his face (body language) , is not it?

This was very impressive , you just need to look carefully at his body language , and guess what , the possibility of what is in his mind to influence the behavior speerti ? ! Simple is not it? Yes , very simple , as you just have to know and understand very well the pattern or system of the human mind works , with the capital , you will have " kanuragan " read the mind of others.

types of women

                What about body language is almost out of sight, movement resembling normal movement ? This is what I mentioned earlier, you need to really understand system'nya , and you also need to learn from yourself, when you are nervous, what movement you show your body posture ? Learn its details , sturkturnya , and other trials in the way attention gestures / body language that he had shown .

I will give a simple example , like this : you know? When a child tells a lie, then he will shut his mouth with both hands. But over the development of mind (read : LPB ) , then he has the ability to transform his body language , such as Otis just chuck hand to the mouth with a glance , or scratching near the mouth to cover his mouth , scratching or sweep hand is the change exists body language patterns of a small child to an adult, but the mind still make it behave sadarnya so. See?

Through Mind Reading Body Language A

                Well this one is looking at the body language of deceit through his eyes. wow , cool! ! ! . you know? showed that the human left brain is used to think matters relating to logic , while the right brain is used for things relating to the imagination . Here we can understand , when you move your companion or friend towards his left eye , then it can be ascertained , he is using logic , and vice versa , when he move his eyes to the right , then even sure if he could at being imagine . Meaning what explanation was? So this way, when you ask the question that has logic elements , but your friend move his eyes right collar then answer your questions , guess he is honest or lie? Intelligent , means you have to understand , that your friend is lying , why ? Because your friend replied with imagination , imagine , or stringing a story of imagination results , not based on memories that are already in its natural , when you query contains elements of logic / memory , right? ! .

Examples of questions that should be answered using the logic / memory :

Hey , you come here late last where ?

Sayank , what time you went away , the same one ? ( cieee , Nanya ya girlfriend )

Examples of questions that should be answered with imagination / imagine "

Can you think of a horse -headed tiger ?

Clear enough ? Good , now you start to see the importance of learning about this , right? why ? Of course, since we are social beings who would not want to have to communicate with others , how do we know the person is lying or not ? how do we know what is thoughtless friends or our friends , so we can understand it , until we become good friends ? Yes , read his body language is not just to rely on your hearing to listen to the words in ucapkannya . Interesting is not it ? !

The more you train your awareness of your friend to read your body language , I'm sure , you will be getting trained to be able to read what is running in your mind your friend .

This is even just a small expansion of self- knowledge , that is NLP , Hypnosis or other self-development imu , could you take a lot of benefits, once you learn it.

Safe practice , may be beneficial , and use the knowledge you have learned for the benefit of each other .

hello my friend turned the famous band "the tamper trap" vocalist from Indonesia (Manado) for fans "the tamper trap" would know this.

The Temper Trap is the band's alternative rock genre of Melbourne , Australia . Their debut album , Conditions , published in 2009 with producer Jim Abbiss . They are influenced by Radiohead , Prince , Massive Attack , The Jester People , and U2 . In addition , although The Temper Trap from Australia this band does it all Australians because the vocalist and guitarist of The Temper Trap Dougy Mandagi named a man from Indonesia .
Their songs have been featured in the soundtrack of the video game Rugby 08 , FIFA 10 , pes 2011 and Colin McRae : Dirt 2 . In addition to the song " Sweet Disposition " appearing in the teaser trailer for the film ( 500 ) Days of Summer . The song was also played in the series Underbelly : A Tale of Two Cities , Greek , One Tree Hill , Skins , 90210 , and The Deep End .




All the story of the band The Temper Trap This stems from a young man named Dougy Mandagi . Born in Indonesia, and lived in the family blood is thick with art , make Dougy gained much influence in his musical life . Minor periods Dougy is spent following in the church choir with his uncle and aunt , or listening to his father playing country music on his guitar .

Having wandered here and there , Dougy eventually docked in Melbourne , a city in mainland Australia . And this is where all the magic began . Dougy who is working as a painter photos and not only earn more than $ 25 , met Toby who was a drummer . Dougy then invited him to join , and shortly thereafter joined as bassist Jonathon . Lorenzo the guitarist , who is also an old friend of Toby , join last to complete The Temper Trap . Together this band as frontman Dougy , The Temper Trap have written many songs and occasionally playing small gigs in the neighborhood sekitar.Sampai finally came a legendary producer named Jim Abiss . Successful producer orbit Kasabian and The Arctic Monkey 's even willing to fly all the way to Melbourne just to take care of first album The Temper Trap .

The first album entitled The Temper Trap Conditions , was very well received not only in Australia , but to the United Kingdom to the plains . This was evidenced from album sales , even their first single , Sweet Disposition was booming when the song was used as the soundtrack of a movie called Australia Wide Screen 500 days of Summer . In Indonesia alone , the song Sweet Disposition was once also used as the theme song for the ad Jiffest ( Jakarta International Film Festival ) in 2009 .
The Temper Trap personnel :
Dougy - Vocal , Guitar | Jonathon - Bass | Lorenzo - Guitar | Toby - Drums

trick to take photo waterfall

The waterfall is the subject of an interesting photo and very popular among photographers scenery / landscape . Photographing waterfalls require a particular technique , namely :

Manual camera settings
To get a smooth waterfall picture , we need a slow shutter speed , approximately 1/4 seconds to 2 seconds . The longer we open the shutter , the smoother the waterfall.

Opening / aperture used is actually quite small , such as f/11 or f/16 . With openings as small as it is , the whole scene will look sharp . Avoid openings that are too small as f/22 or f/32 because image quality will be reduced due to the diffraction lens .

For ISO , you should use the lowest ISO , such as ISO 100 ( most Canon DSLR cameras ) or 200 ( Nikon DSLR cameras ) in order to obtain optimal image quality .

lens
For lenses , I propose to use a wide lens , because it gives the impression of depth or three dimensions . Dimensions will be more visible when we vertical composition by incorporating environmental elements such as rocks around the waterfall .

filter
When the photo daytime heat and light once , often a combination of aperture , shutter speed and ISO as recommended above still produce images that are too bright . If that happens , we can use the so-called Neutral Density filter . This filter will absorb more light so the exposure / exposure of your photos to fit . Neutral Density filter that darkens the existing 1 stop to 10 stops of light . I suggest using a minimum of 3 stop Neutral Density filters also called ND8 .

Another filter that can help the Circular Polarizer . This filter serves to reduce the reflection of light so that the image becomes better . Blue sky will be blue and the reflection of light into the water or into the rocks surrounding the waterfall will be lost or reduced . These filters also absorb light by about 2 stops of light so it helps us get aperture - shutter speed settings - ISO is needed . The CPL filter is one of the mandatory filter for landscape photography hobby . How to use this CPL filter is put in front of the lens and then rotate the filter until you get the desired effect ( when the reflection of light is lost / reduced ) .

tripod
Tripod is a mandatory tool for landscape photography , not least to photograph waterfalls . Tripod ensure our pictures do not blur because the shutter speed is slow . Many types of tripods on the market , in general , a sturdy tripod and light it is best for landscape photography or sightseeing .

focus
Appropriate focus for landscape photos is also important , but fortunately we usually use a small aperture setting so that the sharp part of a wider picture . We can choose to focus on the waterfall or beside rocks . Focus depends on taste , which part we want to highlight or seen most dramatically in the photo.

composition
Waterfall photo composition are essentially two , namely horizontal and vertical compositions . Horizontal composition made ​​waterfall scenery becomes more calm and stable , while the vertical composition gives the impression of a dynamic and fast . Do not forget to include a waterfall environment such as rocks , trees , foliage or people swimming or playing water at the waterfall .

Step By Step Learning photography from zero

Learning digital photography is complex . Therefore a lot of people may be wondering how to study .. should start from where ? nah this post seeks to provide practical steps in learning photography .

First of all we need a camera . Based on the size of the sensor , the camera is divided into two , compact cameras and DSLR cameras . Then apabedanya compact cameras and DSLR cameras ? I was just able to buy a pocket camera , if I can not learn photography with compact cameras ? Never fear , though cheap , compact cameras have kelebihantersendiri and do not make an obstacle to learning photography .

Secondly we need to learn about light exposure . The essence of photography is exposure , or total light entering the light-sensitive sensor . Because the light is exactly , the picture is formed . Our role as a photographer is to control the amount of light entering the lens by changing aperture size , shutter speed and ISO . The three elements I refer to as the golden triangle of photography .

Third , we would have to learn our cameras , especially the fashion - fashion , light measurement ( metering ) and auto focus .

Fourth , we need to know what is the depth of focus ( depth of field ) and what the factors.

Fifth , we must know how to take sharp pictures and not blurred .

Sixth , we must study the composition of good photos and interesting .

Seventh , we must study the character of the light , especially the direction and intensity of light .

Eighth , we must learn to anticipate and take photos at the right time .

Ninth , we must learn to tell through photographs , either with a single photo or series of photos.

Tenth , we must learn to process images with digital effects . Sports photos in the digital age is easy to learn and open a new chapter in digital photography .

Similarly, sequence learning about photography for beginners . As you can see , there are many posts that I could discuss each of these steps . Photography is a science that developed so rapidly and have no end , but when confronted difficulties , please do not give up and continue to learn and practice .
