I love the images, the cat and fox the jury is out on but the rest are very special, with regards to IR triggers it's just another tool in the box any one can set one anywhere and get........................nothing really, or their gear nicked
The skill is the knowledge of the subject, it's environment, light and timing the shot which is what wildlife photography is all about IMO
If you go down the more tradition route you could the argue we should all be still shooting film with box brownies! The tech moves on, the tools move on but you still need to know your stuff about the subject, environment, lighting and timing to get the image.
On the plus side on all our travels we may start to find kit just lying around the woods waiting for someone to take it to a nice warm home!
