Water falls photography

Do you love to see the water falls with blurry milky effect. A slow shutter speed can achieve this. Do you want to capture them and see how beautiful they will be. I would like to share my knowledge about capturing the water falls interestingly in a generic day to day terminology.                                              DSCF6618 Exif info: ISO – 64, Exposure – 1.3 sec, Aperture – 7.1, Focal length – 7.6 mm
Have you ever been to grocery shop??? Hope they do have a shutter door, which will be opened in the morning and closed in the evening. After the shop’s shutter is opened customers can enter the shop and purchase what ever they want.DSCF6630 Exif info: ISO – 64, Exposure – 2.5 sec, Aperture – 7.1, Focal length – 6.3 mm Water Stream, Ombattu gudda mountain range, Karnataka.
Similarly, there is a special door in the camera, which will be closed by default. As soon as the shutter button is clicked, shutter door will be opened for a particular period of time and closes immediately. During this time, the light from the subject will be captured by the image sensor inside the camera. So, Camera's shutter door along with aperture will decide the exposure of the subject.                                                        DSCF3308Exif info: ISO – 64, Exposure – 0.8 sec, Aperture – 6.4, Focal length – 5 mm
The speed at which the shutter door opened and closed is called shutter speed. If this speed is high, exposure time will be less and this will results action freeze of the subject (water Fall). In the below picture you can see water drops individually. DSCF1383 Exif info: ISO – 64, Exposure – 0.006 sec, Aperture – 3.6, Focal length – 7.6 mm Talakona Water falls, Venkateswara National Park, Andhra Pradesh.
If the speed is low, exposure time will more and the action will be blurred. In the below picture you can see water drops forms like a line because of the long exposure.                    DSCF1710 Exif info: ISO – 64, Exposure – 0.125 sec, Aperture – 8.0, Focal length – 8.9 mm Water fall, Venkateswara National Park, Andhra Pradesh.
Refer the below picture, the first one is with a faster shutter and the second one with a slow shutter.

Along with the shutter speed, you need to manage aperture to get the desired exposure. Refer the below collage of pictures. The first one with a slower shutter speed  of 1/30 of a second and aperture is f/16, the second one with a 1/60 of a second and the aperture is f/11, the third one is with a fast shutter speed of 1/125 of a second and the aperture is f/8. As the shutter speed decreases the aperture f stops needs to be increased to decrease the amount of light entering into the camera. If you wont adjust the aperture as per the shutter speed, the picture captured may be over exposed or under exposed.depth.gif
Getting the blurry shots during day time is difficult because of more light which in turn effect the exposure time. so, one way to reduce the shutter is by adding the polarizing filter’s. Other things needs to considered
  • Keep the ISO as low as possible to avoid noise.
  • Focus manually and use evaluative metering.
  • Set the white balance to as per the lighting conditions.
  • Mount the camera on a tripod for steady shot. With the slow shutters, even a small hand shake can blur the picture.
  • Use self timer or remote to operate the camera. so that you do not introduce any movement as the shutter button is pressed.
  • Switch on your live view to compose the shot easily,  bending for a long time will introduce noise in your back and results backache.
  • The most important thing is to keep the camera gear safely, moisture can create problems.
DSCF3685 Exif info: ISO – 64, Exposure – 0.125 sec, Aperture – 8.0, Focal length – 8.9 mm Dudh sagar water falls, Goa.
To create interest to the frame, add a foreground subject. The below picture was taken during the Dudh Sagar water falls trek, It is listed as India's 5th tallest waterfall,and is 227th in the world at 310 m. I waited for a long time to capture the water fall with the train on the bridge, finally decided that i had to move as there is no sign of the train from a long time. After covering a distance of 1/2 km, i heard the horn sound of the train and ran back in hurry. Luckily, by the time i reach the view point, the train just  entering the bridge                                     
Be creative, The water stream looks like it is rushing out of the mouthDSCF1055 Exif info:ISO – 200, Exposure – 0.007sec, Aperture – 4.6, Focal length –17.1mm Cave pool, Venkateswara National park, Andhra pradesh.
Follow rule of thirds to please the eyes                DSCF1533Exif info: ISO –64, Exposure – 0.125 sec, Aperture – 8.0, Focal length – 10.4mm
Capture peoples joy to make the frame more beautiful DSCF1681Exif info:ISO –800, Exposure –0.006 sec, Aperture – 5.5, Focal length –37.8 mm
DSCF1955Exif info: ISO – 64, Exposure – 0.2 sec, Aperture – 6.4, Focal length – 5.5 mm
Framing will also adds interest.                             DSCF1989 Exif info: ISO – 64, Exposure – 0.013 sec, Aperture – 7.1, Focal length – 6.3 mm Sathodi water falls, Yellapur, North Karnataka
DSCF3314 Exif info: ISO – 64, Exposure – 0.33 sec, Aperture – 6.4, Focal length - 5 mm
The same effect can be applied to the flowing water tooDSCF5266 Exif info: ISO – 64, Exposure – 1 sec, Aperture – 9.0, Focal length – 14.6 mm Lakshmana Tirtha river origin, Bramhagiri, Karntaka

Nagalapuram Trek–South west mountain range

Nagalapuram forest range, just few hours drive from Chennai, a beautiful wilderness that has become the unofficial home of the Chennai Trekking Club(CTC). We trekked through one of the best trails in Nagala, filled with crystal clear pools, fresh water streams, breath taking views, and beautiful forest.

Me, Ramesh and Alok joined from Bangalore. Reached Tirupati by 4 A.M and borad a bus to Uttukottai and reached Uttukottai junction by 5:30 AM. The other team from the chennai reached by 6 AM. All the team set to go for Nagalapuram. After entering Nagalapuram we had reached Arrey Village. We had parked all the vehicles near the dam

After 45 minutes trek we reached the second pool. It is crystal clear and beautiful with a small water fall. Depth of the pool varies from 1 feet to 10 feet. Had fun for one hour. DSCF0100

After another 30 miins trek we reached the 3rd pool. This is the most beautiful of all the pools with sliding water fall. Its depth is more than 10 meet. Had a great time here

After the water fall we climbed a steep hill and get down into valley on other side and after another 2 1/2 hours trek we finally reached the camping spot. Had fresh water bath, yummy soup followed by Maggie. The next day we work up in the morning and trek down in the same way.
