There are two ways for cameras to measure the distance to an object: they can fire a beam of infrared light at it and measure the time it takes to return or they can look at contrast differences in a small area of the object and adjust the lens until you maximise the difference. The former system was common in early compact digital cameras and may still be found in many camera-phones. The latter has always been popular in DSLRs and is becoming increasingly common in digicams, particularly the more advanced models. Many modern cameras combine both systems.
... [more]Day seven was given over to the El Questro 'experience', with an early start for those of us who wanted to walk into Emma Gorge and swim in the plunge pool beneath the cascade. The track, which was formerly a relatively easy stroll, was devastated in March 2005 when Tropical Cyclone Ingrid dumped 445 mm of rain on the area in less than 24 hours.

[more]Day 5 was one of the highlights of the entire trip: a visit to the Mitchell Falls plus a helicopter trip over the Mitchell Plateau and adjacent coastline.

Our plan was to walk up to the Mitchell Falls, spend some time exploring the area and then board a 'chopper' for the flight over the plateau, which would deposit us back at the road where our truck awaited.

From the car park a short walk took us through the bush to a picturesque, almost circular waterhole formed by a waterfall that cascades roughly 20 metres from the escarpment above.
... [more]Wanting to see more of outback Australia, my partner and I decided to visit the Kimberley region in Western Australia, lured by the promise of spectacular scenery plus a taste of the 'real' outback. Our visit was timed to ensure the waterfalls were flowing but in advance of the peak tourist season, which covers July and August.
... [more]Paper choice is important if you want high-quality, long-lasting prints. The paper must be compatible with your printer and have the right look and feel for the image printed on it. Its surface should also be able to accept the ink without letting it spread. To achieve these objectives, all inkjet papers have coated surfaces that impart certain qualities with respect to flatness, surface texture and ink absorbency.
