Vivid Sydney without the famous Opera House is not Vivid Sydney. I have to add this photo to my collections even though I have thousand photos of the Opera House. But during Vivid, the long exposure and the lighting makes each photo unique.
This was 4 photos combine to make this image. Firstly 3 photos HDR and combined with another photo of the Opera House where I have some what freeze the projecting video on the Opera House. All blend together in Photoshop with a bit of masking.
If the above description was over the top for you, don't worry it takes time to learn Photoshop and Lightroom. If you new to photography then start learning Lightroom first then slowly move on to Photoshop. You will find as I have that post processing could be just as fun as shooting the photo in the first place.
