What is threshold? 

The Threshold tool transforms the current layer or the selection of images, into pictures consisting of only pure black and white. In this, the color of pixel represents something, for example white pixels represent the pixels of the image whose value is in the threshold range, and black pixels represent pixels with value out of the threshold range.

I was inspired by the photographer Keld Helmer-Petersen, whose work was mainly based around this aspect as seen by some of his pictures below. I noticed that his images mainly consisted of every day objects, with a clear definition between light and dark, to which he would convert these using the threshold (As seen below).




This style of photography inspired me to create my own small contact sheet, in which I would incorporate this threshold idea into some of my picture taken previously, using the software Photoshop. This would really make certain aspects of the image that I desired to stand out from the rest, by reverting the image to a black and white only state. However with certain images, I decided to invert the colors as I believed it made the image more aesthetically pleasing to the eye, and in some circumstances made the object I wanted to pop out.

This is the outcome of my experiment:

The method in which I created these images on Photoshop are below:

1. Locate the Image tab above, and click the adjustments section, which will reveal the Threshold section.


2. For some pictures I then had the idea to invert my image colors, allowing for a completely different picture to be formed.
