Ken,

Thanks for starting this thread. So far some great square images from you, Galdolfi and especially Valdecus. I don't think I've ever cropped a LF image to square, until this one inspired by your post. This is from last week and the square just seems to work for me.

Shot with 210mm lens, red filter at f/5.6 on 4x5 Arista EDU Ultra 100 in Rodinal 1+100.
