It’s a known fact to many that I shoot many times per week. While working on an upcoming tutorial for the site on panoramic portraits, I merged a bunch of images together for said tutorial. The exposure stayed constant and nothing about the lighting really changed. However, when looking at the final image that Photoshop Elements gave me, I saw this weird rendering. It looks a bit like cubism and a bit like many photos were printed and literally stitched together. Granted, Picasso’s cubism often involved portraits where one part of a face was in a spot where it shouldn’t be.
In color, it looked awful–but then when converting the processed image to black and white, it looked awesome.
So why did this happen? Udi Tirosh from DIYPhotography figured that since I shot this with a Sigma 85mm f1.4 on a 5D Mk II that vignetting happened due to my shooting wide open. So he believes that the vignetting made the exposures irregular when Photoshop tried to merge the images together. Because of this, I got the weird cubed effect. The fact that I was shooting in a dark atmosphere also adds to the reason why this came out looking like this.
Either way, I personally like it for artistic reasons.
