I know that some cameras such as the Olympus M43s have this as an art filter but is it possible to achieve this effect on a regular camera? I have a Pany GH2. Can I just tweak some settings or is there a special lens for this? Thanks in advance!
I think the ones you are talking about are probably the ones in this thread:There are some good examples on their website.
Here is also a link to a Flickr group with examples, if you go to the 5th page look for the ones taken in the Air and Space Museum. They are hands down some of the best I've ever seen.
