Bowra, Charleville, Quilpie & Eromanga

Part 2 of the trip, The Doc is now in Queensland with stunning sunsets and giant dinosaur fossils. Report here.

Arnhem Land Plateau

A remote creek and waterfall on the Arnhem Land Plateau. It was very humid that day, so taking a refreshing dip in the creek was great, just not to close to the waterfall behind the photographer. It was a big drop. This a stitched panorama, enjoy.

A report and more pictures here.

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.
