F22: Southside Camera Club Newsletter June 2008 June Club Meeting - 7:30pm Thursday 12th at the Canberra Irish Club, 6 Parkinson Street, Weston June Talk Composition – Denis Jessop June Excursion Coordinator: Laurie Westcott Where: THE BIG HOLE When: Saturday 14th June Trip Details: Meet at the Captains Flat coffee shop at 9am. Duration: 3 - 3½ hours from Braidwood (We will be going via Captains Flat) Category: Short Height: 820 metres Length: 4 km HOW TO GET THERE: From Braidwood, take the Krawarree / Cooma Road. Continue on this road for 42 km until you see the Gundillion Cemetery on your left. The turn-off to the Deua National Park and Berlang Camping Area, the stepping-off point for this walk, is immediately after the cemetery. The signpost is easily missed, so take care. WALK DIRECTIONS: From the rest area, the path is clearly marked. As you have to ford the Shoalhaven River shortly after beginning the walk, it is wise to come prepared for wading. After leaving the river, the path follows a gentle upward slope for 2 km to the Big Hole. DEGREE OF DIFFICULTY: TIME ESTIMATE: Easy 3 - 3½ hours total, which includes a 40-45 minute NOTES: drive each way and a 1½ - 2 hour walk This walk is suitable for any time of year. However, Page 1 F22: Southside Camera Club Newsletter June 2008 with the need to ford the Shoalhaven River (knee- deep for a person of average height), it is best to bring a towel to dry off.

It offers five Exposure modes and three Metering Page 2 F22: Southside Camera Club Newsletter June 2008 photodiode captures all the RGB data, so no final- stage demosaicing is required. Brand-new “TRUE” image processing engine The DP1 incorporates “TRUE” (Three-layer Responsive Ultimate Engine), the world’s first image processing engine suited for Foveon three silicon embedded layer direct image sensor. The unique image-processing algorithm, which has been developed throughout the development of the SD9, SD10 and SD14 cameras, is incorporated into “TRUE”. It enables high-speed image processing and high image quality. 16.6mm F4 lens designed exclusively for the DP1 The DP1 is equipped with a 16.6mm F4 lens, equivalent to 28mm on a 35mm SLR camera, which has been designed exclusively for DP1.
