A couple of images have made me think about how artists use cropping as part of their process. I was at Tate St Ives and saw Franz Kline's Meryon as part of their International Exchanges exhibition. Along with the boldness of the mark making and the strength of the image I was struck by the way it overflows the canvas and the sense that the form continues above and below, that this is somehow a cropped version of something bigger.
Staying with the Tate I was thinking of their Prunella Clough archive which I've blogged about before and which contains some of her working materials. One of the ways she transformed the everyday into abstract images is by cropping larger images to focus in on details and to change the context.
Instagram does a similar thing as the square post format is always smaller than the original photo. Sometimes you allow for this and mentally compose your image within the larger camera frame but I also enjoy the process of selecting and framing parts of the image and the way in which this sometimes reveals something new.
