Australian Native Wildflower as Garden Specimen

 

Comment

Chiloglottis truncata grows in forest and woodland between Kingaroy and Toowoomba in Queensland. It was first formally described in 1987 by David Jones and Mark Clements from a specimen collected at Anduramba, Queensland. This specimen was grown from tubers supplied by the Australasian Native Orchid Society in January 2019.

Nice work Dave.
Have you considered the use of a UVA converted flash for your UVA & UVIVF photos ?

[Andy Perrin]

Colin, it says that middle one was made with a Nissin Di866 Mark II flash. There is no benefit to a flash for UVIVF I don't think.

Stronger light, less noise ?

I use the gear that I have put together with very few changes since I started, it does the job "If it ain't broke don't fix it". I tried without much success to do UVIVFL (in the bush) but gave up and decided to only take my UVIVFL photos in my converted darkroom. You will see where I only take Visible and UV pairs that they were taken in the bush.

You just take a longer exposure. Especially in a darkroom, exposure time is not an issue.
