Top Travel Tips

Here’s our Top Travel Tips for Photographers:

1 Take your charger, even if it’s only a weekend away! Charge the battery every night to ensure your camera is ready when you need it. And remember, cold weather shortens the life of batteries.

2 Take lots of memory cards. They’re cheap, and why risk missing out on that once-in-lifetime shot because your memory card is full? Make sure you format them in the camera before you leave. If you are planning to take lots of pictures and are wondering whether to buy one big card or several smaller ones, we recommend buying many smaller ones. If you lose the one big card, or gets damaged/corrupted in some way, you will lose all your photos.

3 With this in mind, don’t be scared to take one extra photo. You may never come back! Also, don’t delete a picture off the back of your camera without first looking at it in on your computer. The camera’s screen is too small to have a thorough look at the image and you might miss something interesting in the background.

4 Backup the pictures! Keep the used cards separate from your camera (and secure) in case it gets lost or stolen.

5 Be aware of visiting places where taking pictures may not be condoned or may be against the law. As a rule of thumb, avoid photographing inside airports, at border crossings, where there are police or military officials etc. Respect signs that say “no photography”. Also, different countries have different laws about what is acceptable as far as photographing people – research this before you go!

6 If you don’t have a tripod, a bin/chair/or the ground can be a great makeshift tripod.  

7 If you are taking pictures at night, and the camera suggests using a tripod or you cannot get sharp photos because the shutter speed is too low, you can use your camera’s self-timer for a hands-free shot that minimises camera shake.

8 Use your shadow as a guide. It’s best to keep your back to the sun when taking pictures so if you look down and see your shadow you’re looking the right way. Of course this is not always possible.

9 Be creative and don’t forget to change your point of view. Don’t just arrive at a scene and take the first shot you see. Remember to think about WHAT you would like to highlight in the scene.

10 Keeping a shopping bag in your pocket or camera bag is a great way of protecting your camera if it rains.

11 Test your camera before you go away. Learn how to use it, and try not to buy it the week before you go away. If you’re flustered and have not read the new manual or are not familiar with the camera, you may not be getting the best out of it.

These tips will ensure that you capture some awesome memories of your trip. And on a final note, make sure you have the camera ready at all times – you never know what’s around the next corner.

Try This

While traveling, keep your camera handy and ready to take photos.  Try to get some shots that are a little different from the norm, using a different angle or perspective.

Do a Photography Challenge

What is it?

Doing a photography challenge lets you explore new things, try doing the same thing many ways, or just explore your creativity. Some examples could be, Photo-A-Day for a week, a month or longer, portraits of strangers, macro, or there are some creative subject lists for 30 days, that make you become more creative.

Photography ChallengeHow do I use it on my camera?

How you use your camera in this challenge is up to you. You could limit yourself to only shooting with Aperture Priority, or just using one lens, or only using ISO100. Whatever you choose, make sure that it makes you think about what you have to do to take those pictures.

What does it do to my pictures?

These sorts of challenges will make you become more creative. They will change the way you think about how you’re shooting, and how it make you see things in a different way. If you choose to only use F3.5 or all your pictures are going to be taken at 1/100th of a second, these challenges will keep you on your toes.

Examples

Here is my 365 Photography Challenge, as I love photographing wide angle pictures; I decided to challenge myself to use a telephoto lens, and to only take pictures with it at F2.

One Hundred Strangers is a Flickr group with people and portraits in mind. It makes some people come out of their shell, in order to ask someone if they can take their picture, and then post the images with some background on Flickr.

Facebook has a 30 Day Photo Challenge that involves each day having a different photo to submit. This would challenge you to think outside the box, and be a little more creative. 

Try This

Do a one week challenge, try to push your boundaries and extend yourself. If you’re stuck for ideas, our challenge is to photograph something green for seven days. You can’t take a picture of the same thing seven times, each photo has to very different, and needs to be a completely different subject matter. Seven photos of leaves won’t cut it!

Here are three pictures to start you off,

RAW

What is it?

RAW is the digital equivalent of slide or negative film. It’s a format that allows you to process the image after you have taken it to suit your liking, or to process it a very different way altogether. In short, it’s like the roll of film you used to take to be developed, and then go back to get your prints. With RAW, you do the developing.

How do I use it on my camera?

Usually your camera is set to take photos in .jpg format. This format gives you a processed picture that is ready to share or print. Depending on the make and model of your camera, you may have a dedicated button for selecting the RAW option or you may have to change it through the menu system. Your camera may be able to take both a .jpg and RAW image at the same time, or just one format. This function may allow you to choose different .jpg and RAW sizes as well. Please note: shooting RAW will produce large file sizes and will slow down your camera’s burst mode (ie, how many pictures you can take quickly in a row.)

What does it do to my pictures?

Shooting RAW gives you much flexibility when processing your images. It allows you to adjust every facet of your image, from brightness, colour, contrast, sharpness and lots more. Newer versions of Photoshop Camera Raw Editor even allow you to apply a graduated filter effect, remove dust spots and other unwanted elements in the image. Basically, you can manipulate your picture to your hearts content.

You may be thinking, “we can already do that with editing software for our .jpg files”. Yes you can! BUT, like slide film, any change made to a RAW file is just a tweak to the file. It is not destructive, which means that any change can be reversed, or improved with more changes. You can always revert to the original RAW file. Even cropping the image does not destroy the remainder of the picture, not to mention that in the future, there may be better software or you may have a better understanding of processing that could give you a better result.

Once you have made your adjustments to the RAW file, simply save as a .jpg for printing / sharing.

While you may not be able to process a RAW file now, it is worth shooting in RAW, because at some point you may be able to, or you may want to change the feel of a shot. Processing software will improve over time and will allow you to produce a better result!

The following examples show images that I took years ago, and have been able to re-process because I kept the RAW files.

Example 1

RAW Pics 1.jpgI took the picture above in 2004 on a then new Canon 300D (using a 18-55 kit lens). The picture settings were F16 (aperture), 60 seconds (shutter speed), and ISO 100. I processed the image with the Canon Raw editing software supplied with the camera.

RAW Pics 2.jpgI can now process that file with the latest Adobe Camera Raw Editor. You can see the many sliders and variables that can be used to adjust the look of the image. Please note that when you open the file, all the sliders are set to 0.

RAW Pics 3.jpgIn this image, I have moved the sliders, and the image has changed:

  • Moved white balance – toned down the yellow cast

  • Increased exposure – increased the overall brightness

  • Increased contrast – blacks are blacker and whites are whiter

  • Decreased the highlights – which remove some of the extreme white light around the street lights

  • Increased clarity – which sharpens the image

 

RAW Pics 4.jpgHere is newly reprocessed image. If I had not taken this picture in RAW in 2004, these edits would not have been possible.

Example 2

The photo on the left was taken on a Canon 1000D. The settings were F2.8, 1/750th shutter speed and ISO 100. The photo on the left was as shot, you can see that it is quite overexposed, as this image was taken in RAW i am able to repair the image and bring it back.

  • Decreased the exposure –  to darken the overall image

  • Increased contrast – blacks are blacker and whites are whiter

  • Increased the highlights – as they needed a little

  • Increased the shadows  – to highlight the flower

  • Reduced the whites – to remove the harshness on the lake

  • Increased the clarity – to sharpen the image

If this was a jpg image out of the camera, these adjustments would not have been possible.

Try This

Take a picture in RAW and have a go at processing it yourself with the sliders, moving each one at a time and seeing the results. Watch how the histogram moves left to right and how the peaks rise and fall.

Shutter Speed

What is it?

Your camera has a door that opens to let in light; by controlling how long the door is open it can control how much light comes into your camera, and therefore how light or dark or your photo is.

Shutter Speed is how long the door is open.
How do I use it on my camera?

Shutter Speed Pics 1

Depending on the make and model of camera you have, by using the S or Tv mode on your camera dial or menu, you can select the Shutter Speed that you want the photo to be taken at. The camera will then set the Aperture to maintain the correct exposure. You can use the main scroll or menu to change the Shutter Speed. Your camera is likely to have a range of 30” to 4000 or (1/4000th), this is 30 seconds to 1/4000th of a second. It may also have “Bulb” or faster than 1/4000th. I will leave “Bulb” and Long Exposures to another Blog post.

What does it do to my pictures?

The longer the shutter is open, the more that the objects that are moving  in your pictures will blur. So to freeze your subject in time you will need to use a quick shutter speed. To blur your subject you will need to use a longer shutter speed. Tip: if you are trying to capture your kids on a swing, you will need to use a faster shutter speed than 1/250th.

Shutter Speed Pics 2Fast Shutter: has frozen the seagull in flight.

Shutter Speed Pics 3Slow Shutter: the waves in this picture have a ghostly appearance.

Examples

Shutter Speed Pics 4Fast Shutter: has frozen the subjects mid jump.

Shutter Speed Pics 5Fast Shutter: the movement of the water is frozen.

Shutter Speed Pics 6Slow Shutter: the water on the waterfall has blurred.

Shutter Speed Pics 7Slow Shutter: the cars are so blurred they are not visible. All you can see is their headlights / tail lights.

Try This

Set your camera to Shutter Priority mode. Using a garden hose or sprinkler, take a picture at 1/1000th and see what happens to the water.

Next, take a series of pictures of the same object, changing the shutter speed after each photo. Note how your pictures are changing. What else is changing when taking these pictures? Feel free to leave your comments on this post.

The making of Natural Bridge HDR

What is HDR?  Why would you use it?  What is it good for?
HDR 131227 Natural Bridge 242-249

The simple answer is this.

HDR is an acronym for High Dynamic Range

What is Dynamic Range?

It refers to how we see light and what we see. Its measured in stops of light, our eyes see about 13 – 14 stops of light, most consumer digital cameras will record about 9 stops of light.

We can see details in the bright and dark areas of a scene that our cameras cannot record. In some cases it is the answer to “Why don’t my pictures look like what I was seeing”.  

This photographic technique allows you to get more detail into your pictures than your camera is capable of recording by taking multiple shots that are set to different exposures and combining them together.

Usually three or more shots are taken: underexposed, correctly exposed and over exposed (-,0,+).  Your camera may be able to do this automatically with a function called “bracketing” – your manual may explain this in further detail. These multiple images are then blended with third party software or in camera to create one image.

This technique is handy when a scene is unevenly lit, an example of this is a place called Natural Bridge, its in the Springbrook National Park in Queensland. There is a wonderful sun lit waterfall in a cave.

The shot below is exposed for the light on the waterfall and the light outside.

HDR 131227 Natural Bridge 242_1

Note that there is no detail in the underside of the cave, but the rainforest and waterfall are exposed properly.

This next shot is exposed for the underside of the cave.

HDR 131227 Natural Bridge 249_1

Note now that there is no detail in the rainforest outside and there is little detail in the wall and the waterfall.

The next shot is in-between both of the two shots above.

HDR 131227 Natural Bridge 246_1

There is loss of details in the darker areas and loss of details in the rainforest, but there is nice light on the rocks in the foreground.

If we combine these images using HDR processing techniques, we will get the composite of the lights and darks. You can now see the details in the underside of the cave and the details in the rainforest.

HDR 131227 Natural Bridge 242-249

This image was combined in Photoshop, using the built in HDR tools. Some of the newer cameras will process this style of image in the camera.

Some people believe that this is no longer photography, and is more akin to art. I believe that if you need to use this style or process to record what you see, then do it.

ISO

What is it?

It is an international standard for measuring the sensitivity of light of film. But we now mostly don’t use film. So how does it relate to your digital camera? Why do you need to know about it?

Digital cameras may not use film, but the sensor recording the image uses the same sensitivity scale outlined by the ISO standard.

In film days, ISO 100 film was used outdoors where there was lot of light. 400 film was used in the shade and 800 was used indoors with flash.

Most modern digital cameras, have a range of ISO from 100 to 1600 as a minimum, with some cameras boasting much higher.

How do I use it on my camera?

Depending on the make and model of your camera, you may have a dedicated button for changing it, or you may have to change it through the menu system. Most of the latest cameras will have an intelligent Auto ISO that allows you to set a minimum and maximum value.

What does it do to my pictures?

The short answer to this question is, not a lot! By increasing the it when taking your picture it will allow you to take a picture in a darker environment. So as a general rule always use ISO 100. If you cannot take the picture at 100, then change it. As the light around you gets darker, you will need to increase your ISO to match.

 Technology has made ISO nowadays just a number, gone are the days that 1600 was “noisy” and you lost detail in your pictures when using it. The new Canon 700D allows you to use ISO 6400! That film speed even 5 years ago was considered unusable.

Examples

ISO GS NoGreenSquare The picture above was taken in 2007 on a then new Canon 30D, the picture settings were Aperture F5.6 Shutter Speed 1.6 seconds and ISO 1250, the image to the left has been processed to look like it was taken on a 1000D at the same ISO, with newer technology that has better ISO, there is less noise.

NGS NoGreenSquare ISOThis picture was taken at 3200 at about 9.30 at night, the high number allowed me to take this picture where the only light available was moonlight. The Aperture was F2.8 and the shutter speed was 1/60th.

NGS NoGreenSquare ISOThis shot is a crop of the original shot to show the noise that was around with older cameras, this was taken on a Canon 300D, the settings were Aperture F3.5 Shutter speed 1/160th and ISO 1600, you can see the grain mostly in the darker areas of the image.

NGS NoGreenSquare ISOI have reprocessed this image and reduced the noise but there is still a little evident. Newer cameras will do this for you in camera without the need for reprocessing.

NGS NoGreenSquare ISOThis image was taken in such a dark setting that the camera needed a torch to focus! The settings were Shutter speed 1/10th Aperture F4 and ISO 1600, the settings were used to bring out the background that was extremely dark, the couple were lit by two flashes.

Try This

Set your camera to Manual mode. Set your camera to Aperture F16 and Shutter speed 1/100 and ISO 100, take a picture, then change the ISO to 200 and take the same picture, then repeat for 400, 800 and 1600, what is happening to your pictures? What else is changing?
