I am an amateur photography and although i have taken long exposure photos before, this is the first time for a while and with my new camera Canon EOS1300D.
I am surprised at the blurry result. The photo was taken on a sturdy tripod with 2 sec timer delay. Aperture 29 and 30 sec exposure. Iso 100. I was in our house and there was no wind.
Lens 18-200mm tamron.
Am I missing something or forgotten some basic photography skills?
Although I call myself an amateur, there were some basics that I was sure I had got right. For the record, the initial photo in question was taken in clear view. There were no windows or any sort of obstruction. Also, the tripod was sturdy and I was surprised that the second-floor flooring might make such a difference. Saying that, these are all possible options.
After some testing, I have come to a solid conclusion that the issue only occurs when the 'VC' function on my Tamron 18-200 mm DiII VC Zoom Lens for Canon is turned on. Below are two pictures taken. The blurred one is with VC on and the good one is with VC turned off. Both on a tripod 2 sec delay; 30 sec exposure and 29 aperture. 100 ISO.
Looking at the website I purchased the lens through, the VC function is "Three-coil electromagnetic VC image stabilization system provides a 4-stop handling advantage for significantly sharper images"
So my question now is; Is my lens VC function working? Perhaps the VC function is not meant to be used for long exposure shots. This is beyond my expertise.
