Light and Shades
This image reminds me of some that you get with edge-detecting artistic filters, but the curious thing is that it is created just using ‘statistical’ stacking and blend modes, with a little general tonal adjustment.
Five captures were stacked in Affinity Photo though you can do the same in Photoshop. My initial objective in taking the images was to get rid of the pedestrians that were wandering around. If you stack a number of images using the Median function then provided the pedestrians are moving about you can usually get rid of them without any selections and painting. The median function works by taking the most common value for a particular pixel in the stacked images and using that in the result.
But then my brain aroused itself from its usual torpor (concerning!) and asked ‘what if I just….’ (extremely worrying!). So I tried some of the other stacking functions, some of which gave interesting results.
This image is a combination of a Median stack, with no pedestrians, and Variance stacks which had dark ghosts of the people wandering about, blended together a number of times using various blend modes. Some of the ghosts appeared twice in different places :)
But what you really want to know is where the images were taken (I realise that I’m kidding myself). This is the Bridge of Sighs in Oxford. It joins two parts of Hertford College across New College Lane. It’s named after the famous Venice bridge. Cambridge also has a Bridge of Sighs so I am sure there was a bit of rivalry going on as there often is between these two universities.
I was a bit disappointed to discover that this particular bridge was relatively new, constructed in the 20th century (around 1914 - the Cambridge one predates it by almost 90 years).
As it’s heavily processed I thought I would post it for Sliders Sunday.
Thanks for taking the time to look. I hope you enjoy the image. Happy Easter and happy Sliders Sunday :)
