Now while i have lost track on the advances in photography over the years , these puzzle me

Whilst it can be reasonably assumed that the majority are long term exposure

Texture of the Thames

Car light trails

People sitting in Trafalgar Square

I am at a loss as to how it was done, esp of the one taken on Westminster Bridge where the hands on the clock appear to show no movement

Is it all digital jiggery pokery?

Could be layering. A few pics layered and then cut the bits you don't want from each later. Enough shots and layers and you eventually will get a empty pavement etc.


That's my guess.

From the comments

"Get a camera, add an extremely strong Neutral Density filter, boom, slow shutter means no people in the shot."

I have no idea what that means though.

Thanks Dave didnt see that

Now it is all clear!!!

sonys even have an app for this takes up to hundreds of images and combines the results

The way I did mine, because I didn't have a neutral density filter to do a long exposure, was to put the camera on a tripod and take lots of images. All those images were then stacked in photoshop where I was able to cut out the people from each image. With enough layers, eventually it was possible to find parts that made up the entire image with no people present.

Photoshop has an automated feature to do that

Even an ND filter won't get rid of parked cars though!

My Hasselblad one does...

No need for cutting out the people, I think it is the median stacking feature the does it automatically.

You could do it old school and just go early Christmas Morning. A friend of mine did it one year. The only people around were joggers and photographers.

Anything done around the square mile could easily be done on a weekend day, nobody in the city works weekends and almost nobody lives there either.

This was taken at 17:30 on a Saturday afternoon in December a few years ago, at 08:00 on a Monday morning you'd struggle to see the pavement due to the number of people walking through here.
