The lighting in this shop is bright enough to work in but not for low ISO photography. I set the ISO to 6400 thereby increasing the sensitivity of the camera sensor. The slightly grainy appearance is a consequence of the high ISO setting and the fact that this photo has been seriously cropped (I could not safely get too close to the action and I did not have a chance to go get a lens with a longer focal length). The slightly grainy look doesn't bother me in the least; in fact I think the photo is all the better for it. Cyanotype conversion made using Nik Silver Efex pro software.
