Andrew Tisdall

I bought my first SLR camera as a teenager in 1974, for the next 4 years I shot mainly "street" in black and white negative using the college darkroom for my printing.
Nowadays in the digital age I use Micro 4/3rds cameras often with the same lenses of my youth and would describe my style as experimental or as my wife would call it, "just weird".

Star Trails

This was taken in Spain, it is a live view composite of over 500 exposures of 20 seconds (about 3 hours at F2.8 iso 200). The camera only records pixels that have changed from the previous exposure, so static objects do not become overexposed.
The small bright arc in the centre is Polaris.

Curl Curl

This is a photo taken high above Los Angeles of a sunset between two cloud layers, the red is the Sun and the orange is caused by the smog below.
The spiral effect was done in photoshop. The term Curl was first used in 1839 by Irish mathematician James MacCullagh in his work on optics.
