Description

Some time ago my remote set up in southern Spain took a series of objects, the processed images of which I will gradually post over the coming days. Alas, due to an unforeseen need to change the camera, which is yet to be fully completed, the data from that time was, sadly, only in luminance - and will always be so. I hope you enjoy these monochrome images even so... 21 subs at 10 minutes long each.
