An ISO Blunder
Sony A500 catches a tiger and poachers at ISO 12,800
Sometimes, mind lapse is a serious problem for a senior citizen like myself. I set my Sony A500 on a trail just inside the boundary of my favorite protected area in Thailand. This location has already produced some amazing shots of black leopard and tiger plus many prey species like elephant, banteng, barking deer, sambar and wild pig.
Tiger passes the Sony A500…!

On the negative side of things, this cam has also caught poachers and gatherers as they illegally sneak into, and exit the sanctuary. Poor patrolling and enforcement with many loopholes allow these undesirables to penetrate and poach animals and forest products for sale or personal use. It is a serious threat to all of Thailand’s protected areas and is on-going problem for the Department of National Parks (DNP)…!

This Sony has been working very well catching a male tiger with a radio collar at night several months ago. I noticed that several people on the forum were setting their cams at ISO 200 and thought I would give it a try. When I left the cam, I thought it was at the 200 setting.
A month or so later, I went back to change out batteries, card and desiccant, and saw the same tiger with a collar had visited twice plus some poachers caught using the same path. When I downloaded the images, I was shocked to see the ISO at 12,800…what the heck happened here…?
I don’t know but it looks like I did not save the settings before buttoning up the cam and somehow pushed the 12,800-button. This was of course another disappointment. The shots are cluttered with noise and I have tweaked the images but it’s a fact: photos with ISO this high is absolute rubbish and can only be counted as record shots.
Another thing: only one flash on the right was working hence the deep shadow. I found a broken wire on the other flash so brought the whole unit in for repair. I will be setting another Sony (A55 with a 55mm lens) DSLR cam with 4 flashes (hard-wired) to see what might pass-by.

The A500 cam is now back in the forest but at a new location with settings at ƒ8 – 1/125 – ISO 200. It was working well firing off 4-shot strings during walk test and hopefully it will produce some good shots now. Leopards and tiger plus all the other denizens of the Thai forest use this trail so I can only wait till I get back to the cam in a couple weeks.……!
