Quilpie sunset at Lake Houndraman

The Doc previously posted a sunset at Quilpie during his last road trip. There was actually a series of photographs, here is a selection. Yes the colours changed from orange to bright red and finally to pink near the end of the sunset. Click on the images to see the full size, enjoy.

Goulburn River, Warrumbungles and the Pilliga

The Doc’s last trip visited Central NSW and Outback Queensland to visit an AWC Sanctuary and visit collections of dinosaur fossils.

Part 1 concerns NSW, the Report is here.

Focus stacking in the field

It is been a while since The Doc’s last update, the to-do list was fairly long after the last trip. Sometimes blogging must wait.

One thing The Doc been working on is a quicker way to create focus stacked images in the field. This is primarily aimed at textures like bark, leaves, flowers, etc.  The Doc is now using the Post Focus feature in a Panasonic Lumix G9 camera using an Olympus 30mm or 60mm macro lens.

The Post Focus feature can be used for focus stacking. Post Focus is a two-stage process. After placing the camera in Post Focus mode and pressing the shutter release the camera finds all the focus points in the image and then takes a 6K video of all those focus points. The process takes about 2 seconds after pressing the shutter release. The lens must be in autofocus mode.

You can stack images in-camera using the G9’s touch screen or use a program like Helicon Focus. I created some images from a recent visit to Mount Annan Botanic Gardens, The Doc used Helicon Focus in post processing (Helicon imports the 6K video then creates a super sharp focus stack). It was a windy that day limiting my subjects to barks from the Corymbia family. Below are a few images (click on image to see full size). This is a link to a 3D video of the one of the stacks, here.

Textures of the Australian Bush: Northern Territory

New report of the textures of the Northern Territory has been posted, here.

Ormiston Waterhole & Gorge – West MacDonnell Range

As noted in the last blog post, the first part of the week was hit and miss. While Rainbow Valley was impressive, the Rogue’s Triangle of Uluru, The Olgas and Kings Canyon was not. Kings Canyon was $40 per night for a single unpowered site! Ulura was $45! Plus the access fees. So The Doc gave both a wide birth, which involved more travel.

Diesel was $123.9 a litre in Alice Springs, 200km south at Erlunda it was 52 cents a litre more, and over $2 at Ulura. It comes to a point where a fair profit margin becomes a rip off. The Doc turned around and avoided the Rogue’s Triangle. If you want to visit these places, pay a travel provider and be ripped off in style – these locations are now hostile to the average traveller.

Sadly The Doc has not seen so many places, so close together requiring you so often to put your hand in your pocket – no other place in Australia is like it. Even at Standley Chasm the access fee is $12.

In contrast, the $32 entrance fee to the Alice Spring Desert Park was a worth every cent. While the fee seems high, the value for money was excellent, great displays, several walk in aviaries, nocturnal house with rare animals and the list goes on. Visit while in Alice Springs, as it is about a 7 minute drive from the highway along Larapinta Drive. A single morning in this one location shows you what could take months in the field to see.

So the week was not going well until the Doc drove into Ormiston Gorge Campground, when things changed for the better, nice grounds, showers, shade and the gorge a short walk away. Up early the next morning for a sunrise photos at the gorge, but the light was not right until around 9am. Then a walk along the gorge, with a climb up to the lookout. A steep decent and a bacon and egg sandwich was the reward at the end. Then off again at around 11am.

A visit to Grosse Bluff was interesting. It is an imposing bluff on the northern side, but the track takes you into a picnic area in the centre where you are surrounded by walls– it turns out it is a meteor crater. The cataclysm when the meteor landed must have been big, no humugous.

The waterhole and gorge also had many large Red River Gums and their amazing textures. Enjoy.

Back to Finke Gorge in the morning.

Bell Gorge – Gibb River Road, The Kimberley, Western Australia

One of the iconic destinations on the Gibb River Road in The Kimberley is Bell Gorge. The Doc will let the pictures do the talking. Remember to click on the image to see the full size (the thumbnails are blurry). Enjoy.

A living dinosaur – the Wollemi Pine

In 1994 a Park’s Ranger was hiking in a remote part of the Wollemi National Park (pronounced Woll-a-my), in the Blue Mountains near Sydney. He came upon an unusual pine he did not recognise and took a sample. It was later identified as a pine that had survived for over 200 million years. The only previous records were fossils. In this remote location, a single stand of the tree had survived.

It was named the Wollemi Pine (Wollemia noblis) after its location and the Ranger who discovered it. The location remains secret but some fools have walked in and took a disease with them, Phytophthora cinnamomi.

These photos come from one of 2 pines at Mt Annan Botanic Gardens in western Sydney. One picture is the cone and the other showing new growth (lighter green) and the deeper coloured old growth. Click on the images to see full size.

An intense cultivation program was started so you can purchase the pine in many nurseries now.
