Hi Christina
The blur comes from the orton effect. I first edited the color version with orton effect and then converted it to B&W.
For the colour version, this is the first time I have used so strong colours. Singh Ray has some special polarizing filters to create very strong colours , when I watched a video about those filters I was amazed. For the time being I'm just trying the techniques, tools and some styles but I don't have my own style yet because you know that I'm new, it is too early for that. So, I think everything will be clearer for me in the future, when I decide what to do particularly
I have some sunset shots with sea and an old wooden pier and I have thought they might look good in B&W. I will try and upload one of them soon if it works fine.
