Want to take beautiful photos of waterfalls?

Want to take beautiful photos of waterfalls? Do you like that milky/silky smooth effect in waterfall photos? You can take such photos too, in most situations, with most cameras. It is not difficult. However in following cases it becomes a sort of challenge.
* Most smartphones or fully point and shoot cameras in many situations will not be able to take such photos. You need a camera that offers some manual controls.
* If you are looking at the waterfall in broad day light, many cameras may run into limitations. In a sort of low light, you are in good luck.

During my tour of Big Island, Hawaii, I came across some waterfalls. After some trial and errors, I was able to take some nice photos with a FujiFilm point and shoot camera.

The first photo I took in auto mode did not take a photo with the silky feel. So changed the camera to Tv/Shutter priority mode and made some adjustments. In few minutes, I was able to take nice photos.

Here are some tips for you.
* It is important that you have a tripod. If you don't have one, find a flat surface where you can put your camera. I didn't have a tripod either but I was able to find a place to put my camera. Many times, I use the strap and put it under the camera to create the angle I need. Takes some time to figure out but if you are lazy like me and don't want to carry a tripod, , this is a small cost. In my experience, in 80-90% of the situations, I am able to find a flat surface to put the camera on.
* Set the camera to Timer mode- 2 seconds or 10 seconds delayed mode. This helps eliminate the shake due to pressing of the shutter release button.
* Change the mode dial to Tv or S mode- Shutter Priority. Set the shutter speed to around .5 second or so. Then if needed, you can change it to 1 second or reduce it to .25 seconds or so.
* Set ISO to 100. If your camera lets  you set the ISO, set it to 100 or the lowest value.

You are all set. Take a photo and see if it comes out well. If the effect is not strong, you can slow down the shutter speed. Let the shutter stay open a bit longer. If the photo comes a bit washed out, you need to reduce the light. To reduce the light, keep the shutter open for less time. In other words, make it faster. As we are shooting in Tv or S mode, camera will choose the Aperture value for us. If you are a bit advanced user, you can shoot in M or Manual exposure mode. Start with Shutter-speed of .5 seconds, f 8 or so and ISO 100. Then as needed, change the values.
If you are shooting in broad light, your photos are likely to be washed out with such a long exposure. One solution to reduce the light is to use ND Neutral Density filter. This filter is like sunglasses or a tinted film. This can help you shoot with longer exposure without getting your photos washed out. In case if you don't have the filter, you can try to put your sunglasses in front of the camera (make sure you clean them) to reduce the light getting on the sensor.
Try this out and let me know if this helps. As I keep saying, if you help your camera, your camera will help you take nice photos. Also, you can take good photos with almost any camera in most of the situations.
Happy shooting.
Here is one more photo I took on that day on the Big Island.

Want to take photos of stars? Here are some tips.

During my recent visit of Big Island, Hawaii, I was at the Volcano park one evening. As it started getting dark, the sky started filling up with stars. I was busy shooting the red flames of lava and suddenly noticed the stars above me. Unfortunately, I was running out of time as my family wanted to go find a place to eat. I tried to take few shots but I had no luck. Taking good photos of the star-filled sky is a difficult job. Expensive equipment does have an advantage here. An iphone or a compact camera can not help you take nice photos of the sky. An SLR with a kit lens can help you to some extent but a Full Frame camera with an expensive/fast lens can help you a lot.
The next day, I was visiting Mauna Kea and had decided to try to take some photos of stars. I googled to get some tips for astro-photography to make it easy. Then I brought along few lenses and tripod with me. As it started getting dark, there were even more stars than the previous night. It was cold but I was determined to try my best. After some trial and error, I was able to take some decent photos.



If you also want to try to take photos of the sky at night time, here are some tips:
  • Pick your best/most expensive camera. Bigger the sensor, better it will be.
  • For lens, try to pick a wide-angle lens which is also a fast lens. I know it is difficult to find a wide angle lens which has also a wide open aperture. I didn't have such a lens so I used the kit lens of my Pentax K-30. In some photos, I also used a cheap Fish-eye lens (8mm Rokinon)
  • Focus the camera to infinity. If you lens has the distance marking, just move it to infinity. Then change the Camera from Auto-Focus (AF) to Manual Focus (MF). Make sure the focus ring does not move. If you have a tape, just tape the focus ring to lens body so you don't lose focus ;)
  • If you camera has Long Exposure Noise Reduction, turn it off.
  • Set camera to Manual exposure mode. In the manual exposure, you will need to set ISO, Aperture and Shutter-speed.
  • Set ISO to 3200 or even 6400. 
  • Set Aperture to the most wide open value you can get. 
  • Set the lens to the most wide angle (lowest mm value). As I had a kit lens, the lowest I could go on 18-55mm, was 18mm. (I also tried with a fisheye 8mm lens. The wide angle photo above is with the fish-eye lens)
  • Set the shutter speed to around 10 seconds.
  • Change the camera to timer mode(2 or 10 seconds) or use a remote control so the shake due to pressing of Shutter Release button is minimized.
  • Place the camera on the Tripod and start shooting. If you are not getting good many stars, either increase ISO, reduce f (aperture value) or show down the shutter speed to 12, 15, 20 seconds.
Trial and Error will help you get better photos.
