Barrenjoey Lighthouse, NSW

At the end of September 2013, we watch on the news as fire broke out at the Barrenjoey Headland in the northern beaches of Sydney. For those not familiar with this area, the beach and the lighthouse doubles as a Summer Bay in the popular Australian TV series, Home and Away.

One week later, we visited the site to witness the aftermath of the fire. It is amazing that the lighthouse and cottages remain intact while the bushland around it was ravaged. Here is the link to the ABC site for some photos during the fire outbreak.

Here are some photos I took using the Nokia Lumia 920.

The National Park rangers and volunteers are looking for volunteers to assist at the end of October beginning of November 2013. If you're in the area or want to volunteer, please contact the rangers.

Photos from Bathurst

These are some photos taken at Bathurst, NSW. I am very impressed with the clarity and detail captured by the Nokia Lumia 920.

It always amazes me our beach culture. On an overcast day, there are still people at the beach.

TIP: Mastering exposure compensation

One of the coolest feature of a windows phone is the ability to change settings. You can change a whole host of features including:

• Scenes
• ISO
• Exposure value (EV)
• White Balance
• Aspect Ratio
• Focus Assist.

A setting you should get use to playing with is the exposure value (EV). This setting allows you to compensate for difficult exposure condition.

Exposure compensation allows you to fine tune your camera's metering system.

When you take a photo, the camera sets the shutter speed based on the aperture and metering system.

The metering system of a camera can be tricked under two types of conditions.

The first is in a scene with the majority of it being black. Good examples include a portraits where the subject wears black. The camera would over exposure this scene as the camera increases the exposure to make the scene neutral grey.

The second type of scene is with the majority of it is white. White wedding dresses often cause underexposure of the image as the camera tries to make it neutral grey.

Exposure compensation addresses this issue by forcing the camera to decrease or increase an exposure value (EV). +/-1 EV is one exposure stop (+/-). e.g. If EV0 (the default exposure calculated by the camera) is 1/20s, EV1 forces the exposure to be 1/10 (1-stop slower). On the opposite end EV-1 forces the exposure to be 1/40s (1-stop quicker).

On a recent trip to Jenolan caves, the default metering would result in overexposure. This is due to the white subject matter and the lights used to light a cave feature. To compensate, I set the exposure value to -2.0 EV, to compensate. The result is shown below.

EV0 the default camera exposure blows out all the detail in the minaret. EV of -2.0 preserves the detail and results in the correct exposure for the scene. 

TIP: Autofocus

There are two ways to engage the autofocus (AF) on a windows phone device. You can either:

1. Use the shutter release button. Press the shutter half-way. This will utilise the center AF area. Once on focus you will hear a beep to indicate that you can reframe your shot. The press down on the shutter button to take the shot.
2. Tap on the subject you want to focus on. This will cause the camera phone to utilise a smaller AF area. It also takes the shot once focusing is complete.

One thing I have noticed with the AF system is that the tap to autofocus is much less reliable than the shutter button method. Here are two shots taken at the same time. You can clearly see the difference.

Tap AF used to take this frame. The focus point was the eyes.

Center AF used to focus. Once focused the frame was composed and shot taken.
