At work we are going to be undergoing major refurbishment so I decided that as well as providing a bit of a record (.....when I was a girl it looked like this!) it would also be an excellent opportunity to practise my HDR technique.
This shot is a merge of 3 shots at F16 1/250, 1/10 and 0"5 using Photomatix pro.
I like how its turned out but there seemed to be a lot of artefacts in the highlights, to counter this I made a new layer put a gaussian blur on it & used a mask to blur the worst of the artefacts.
What I want to know is can I prevent these artefacts from occuring maybe if I were to extend the range of shutter speeds? Maybe I need another exposure purely metered on these highlights?
Thank you for looking and for any help you can give me with this.
I have added a crop of the original showing the artifacts in the versions
