TIPS | Seeing Stars?

Darwin and the Norther..., Tutorials and TipsLouise Denton

A few of you who follow me on Facebook or Flickr will see I've had a couple of recent attempts at taking photos of the stars. This was all sparked by me hearing about the Perseid Meteor Shower. I've never heard of it before this year - it is an annual shower, that provides regular and spectacular meteors for us viewing down here on Earth. Every year it peaks around the 11th of August, and I decided to try and catch my own meteor on camera.


Kakadu National Park

Darwin and the Norther..., UncategorizedLouise Denton

I've visited Kakadu quite a few times over the last few years, but I don't think I'll ever get bored of exploring the area and taking photos! Escarpment country, near Jim Jim Falls, Kakadu

I recently traveled out to the park because Jim Jim Falls had just opened for the dry season. Despite seeing the "falls" three times, I've never seen it flowing due to visiting too late in the dry season. So this trip was all about the "stone country" region, the region of Kakadu characterised by red, sandstone escarpment and gorges.

Jim Jim is the tallest falls accessible in Kakadu - a 200 metre high escarpment - which in the wet season is a spectacular, fast-flowing flood of water. As this falls is not spring-fed and only rain-fed, it dries up late in the dry season. Unfortunately in the wet season, when the falls are at their most impressive, road and walking access become impossible due to the amount of rain that floods the region. I'm hoping to do a scenic helicopter flight next season, but for now I was very happy with the amount of water still flowing from the escarpment.

We arrived at Garnamarr campground around 4pm, set up camp and headed straight down the 4WD track to check out the falls and escarpment in the sunset light. I wasn't disappointed! The gorge-like landscape is stunning, and I was surprised to see so much water still flowing. The light got better and better as the sun dipped below the hills behind me.

The light seemed to be most evenly spread after the sun had gone down, and the escarpment country glowed bright red. The below photo is a composition of 3 photos, to even out the exposure in some dark shadows and too-bright-highlights. The main photo was taken at ISO 100, f13 and 4 seconds, with an area of bright sky above the cliffs brushed in, and the area on the left with the darker trees brushed in too.

We also visited the falls the next morning too, to check out the light. The escarpment did not appear to glow as red, but it was still spectacular in a different way: hazy and mystical - well worth the early (cold!) morning.

The next afternoon we headed to Maguk - a waterfall I was convinced we had previously visited, but on arrival we realised we hadn't! The time we visited was not ideal for photography as the light was harsh around midday, but I think the falls itself would be very difficult to photograph at either sunrise or sunset due to it's position.

The walk to Maguk pool was lovely too, following a creek up to the falls. The creek and backdrop of red, rocky hills would make for some great landscape photography at a better time for light (although I would have to revisit to figure out what that time would be!).

We headed to Gunlom waterfall to camp and stay the night. This place is one of my favourite places to swim - the steep walk to the top of the falls is well worth it! Walkers are greeted with a series of natural rock pools, which end in nature's own infinity pool, looking out in to the vast open landscape of Kakadu.

Unfortunately, this time we did not have time to venture to the top of Gunlom waterfall. Instead, I explored the bottom pools, and photographed the very small trickle left over from the wet seasons rain.

The falls were only a trickle, but luckily there were a few other interesting areas to keep me occupied with the camera!

This tree stands in the plunge pool at Gunlom, and made for a few interesting shots.

My partner and I are thinking about revisiting again for another quick visit to Kakadu next week! I love getting out there, just wish I could spend longer. The next trip we will probably take the boat, so I can try my hand at some more bird/wildlife shots on Yellow Waters. I could already do a long photo essay on Yellow Waters - it's probably my favourite place to relax in the Top End.

More to come soon, hope you liked them! Let me know what you think... I think my favourite photo I took this trip is of Jim Jim Falls, with the reflections of the red cliff tops. :-)

TIPS | Long Exposures

Tutorials and Tips, UncategorizedLouise Denton

What is a long exposure? Basically, a long exposure refers to the length of the shutter speed used to take a photo.

There is no "typical" shutter speed, but in daylight, on automatic settings a small camera might use 1/250th of a second, or maybe even a 1/1000th of a second. As the light starts to fade, or as aperture is narrowed, longer shutter speeds are needed to correctly expose the exposure.

I would consider anything half a second or longer to be a "long exposure". This is definitely too long to hand hold!

The shutter could be open for half a second, or ten seconds, thirty seconds or even four hundred and thirty seconds, if you wanted to!

Why should I use long exposures?

I LOVE long exposures. 95% of my sunset and seascape photos are taken using exposures of half a second or greater. There are lots of benefits to increasing the shutter speed.

Sometimes longer exposures are a necessity, as light gets lower the camera needs a longer shutter speed to create the correct "lightness" (exposure) within the photo.

Depending upon light, and tidal condition, I tend to use between a quarter of a second or one second to create images showing the movement of the water. The water blurs together to create interesting lines and patterns.

Water moving around the rocks of Fannie Bay - a one second shutter speed

As shutter speeds get longer, water tends to smooth out more. In Darwin, I generally use around fifteen seconds or longer to smooth the water - all the water movement blurs together in to one flat surface.

Images using longer exposures tend to get sharper - the camera captures more detail.

Longer shutter speeds can also result in more vibrant colour.

Depending on wind conditions, long exposures show movement in the clouds creating patterns in the sky of the photos.

There are lots of uses for long exposure photography. I use it mainly for landscapes and seascapes, but it can be applied to a variety of subjects.

Below are some examples from Flickr.com:

There are so many more long exposure examples that I want to share from Flickr! Check out more in my "favourites" folder on Flickr.

What do you need for long exposures?

  • A DSLR.

Some compact cameras can be used manually, and you can use long exposures, sometimes up to 30 seconds. Generally speaking, they are capped at a maximum shutter length (and in set increments). DSLRs allow much more flexibility and much longer exposures. A DSLR camera will also allow you to activate the "mirror lock up" setting, improving sharpness in images.

  • A tripod.

The camera must not move! A tripod is essential, and it must be sturdy too. On the beach, this can mean burying the legs and feet deeper in to the sand to ensure it doesn't move with the water.

If you don't have a tripod, you can use a fence post or something else stationary and steady!

  • A remote shutter release.

This is not essential, but very useful. The remote will enable you to take the photo using the remote, instead of the shutter button on the camera. Why? Long exposures require complete stillness of the camera, and often pressing the shutter will cause the camera to wobble slightly - causing blur in the photo. Using the remote means you don't touch the camera, which means sharp photos!

A remote shutter release is also very useful for exposures taken using "bulb" mode. Holding your finger down on the button for 30 seconds, or 360 seconds can be annoying - the remote I use, operates on "bulb" mode by pressing the remote once to start the photo, and once to end the photo.

If you don't have a remote shutter, you can also use the two-second-timer setting on your camera. The shutter is depressed, and the camera waits for two seconds before taking the photo. This gives the camera chance to steady itself and prevent camera shake and motion blur from touching the shutter.

  • ND filter (optional)

To create long exposures in brighter, daylight conditions an ND filter can be used to make the scene darker (therefore requiring a longer exposure to correctly expose the photo). A Neutral Density filter (ND) is a grey filter attached to the front of the lens. They vary in darkness, dependant upon how many stops of light they block. The darkest used is often the 10 stop ND filter, but they also are available in 1 stop, 3 stop, 9 stop, etc. A 10 stop ND filter can capture daylight scenes at thirty seconds.

How do I take long exposures?

I usually use Aperture Priority mode for my landscapes. I generally use between f11 and f16 for my landscape photos. My photos are generally taken between 10 and 20 minutes after the sunset, and using Aperture Priority mode will calculate your shutter time for you (either Av or A on your camera dial). Shooting this long after sunset, with the settings above and ISO 100 will result in longer exposures calculated by your camera.

Using dark ND filters will generally require you to use your camera manually. Sometimes Shutter Priority mode can be used, but personally I prefer to have a control on my aperture instead of shutter speed.

One of the most important set up points with using long exposures is the steadiness of the camera. The tripod must be sturdy, and avoid touching the camera to take the photo.

Sometimes, the environment can get too dark for Aperture mode to calculate your shutter speed for you. Most DSLRs are limited to 30 seconds as a "setting". If you want longer than 30 seconds, you will need to use "bulb" mode.

Bulb mode

Bulb mode refers to the manual mode on your camera that enables you to choose the length of your shutter speed. You will also need to set your aperture and ISO manually.

How do you know how long to do your shutter speed? There is an easy way to work it out (other than trial and error!)

Compose the scene, set up your camera and use Aperture mode to take a test shot. Set your Aperture to the desired setting (e.g. f11). Now, if it is too dark increase the ISO to 200 or 400 and remember the shutter speed it set.

Now flick to bulb mode, use the same aperture (e.g. f11) and reduce the ISO back to 100. To calculate the shutter speed required, using the recommended shutter speed from your "test" and multiply that by the factor of the ISO.

For example, if in Aperture Priority your settings read f11, ISO 200 and 30 seconds, your bulb settings would be f11, ISO 100 and 60 seconds (shutter speed multiplied by 2 - of ISO 200).

For example, if in Aperture Priority your settings were f14, ISO 800, 15 seconds, your bulb exposure would be f14, ISO 100 and 120 seconds (15 sec shutter speed multiplied by 8 - of ISO800)

I think that's the basics to get started on long exposures! Feel free to ask any questions below, or via my Facebook page.

An introduction

UncategorizedLouise Denton

Basically, I want a platform to share photography and ideas with on a regular basis.

When I store my photos on my computer, I file them by date and I have a file for every single day of the year. There are a LOT of photos that I do not post or even look at, because another one or two photos from that day are "better". I want a platform to share the "unseen" photography, or to share photography from a trip, and to share photography from others, share other blogs.

I think this blog will fulfill that.

My passion is the ocean, and the sunsets that go with it, here. So what better way to start than to share my favourite sunset photos from Darwin, over the last twelve months or so? These are all photographs that I have taken myself, found at Louise Denton Photography.

This sunset was amazing! Out of nowhere, as I was leaving Fogg Dam to head home.

This one is after a storm, with the sun setting behind me. I was shooting the opposite direction and looked behind to see a rainbow against the storm glow! at Nightcliff Foreshore

As you can probably see, I like trees! I love just getting outdoors: the Territory is a perfect place for it.

What colours are your favourite? I love the reds and purples, but have found most people really like the blues and calmer colours. Darwin wet season sunsets can be unpredictable - sometimes bright and sometimes very calm.

I think these photos summarise what my work is about!

If you live in Darwin and want to see great photos from our area, you can subscribe.

If you are interested in photography, or learning to take photos - subscribe, as I can share tips, ideas and discuss ways to do things. At the moment, I am researching in to types of torches best for light painting.

I want to visit so many places in the Top End - you can follow this blog to follow my journey. And this can be a place to share ideas - you can comment on my blogs. Before the year is out, I am planning another trip to Kakadu, a trip to Uluru and the Red Centre, via the Devil's Marbles. If I get time, I would LOVE to go through Arnhem land to the Cobourg Peninsular. If anyone has been to these places, share ideas and locations and I can share them back with you!

If you are visiting Darwin, I will be talking about great places to see and go, and events upcoming in the area.
