I'm having a few problems with long exposures. I always get camera shake. I am using a wireless remote, mirror lock is on and it's a pretty sturdy tripod and yet I get camera shake and very blurred images. I've tried everything I can to ensure there's no camera shake and yet I still get blurred shots when I try macro photography.
Camera is Canon 70D and lens Tamron 90mm macro.
I've had to resort to doing everything via flash or with very wide apertures handheld.
Any suggestions?
Thanks
