Summary edit
DescriptionCeiling in old disused mechanical workshop.jpg |
English: The ceiling of an old mechanical workshop, now used as a storage facility in Lysekil Municipality, Sweden. In the ceiling is an air duct, several lamps and a fan. The hall was used for cutting, welding and other kinds of hazardous industry, so the boards in the ceiling are covered with a very smooth layer of asbestos (some of them are still joined seamlessly) and they have been discolored by sparks, flames, soot and other not so nice things for decades. The strange splotches, colors and patterns in the ceiling are from this activity.
The picture is stacked for light, focus and noise reduction by combining 17 photos as layers of varying degrees of transparency in Photoshop. The camera was fixed on a tripod and photos were taken with focus on each feature in the ceiling separately. The ceiling itself was focus stacked from seven overlapping horizontal sections. Additional photos were done with different exposures since the left end of the hall was dark and the right, where the windows are, was very bright. Noise reduction was only done by combining some layers with different transparacy, using this technique. |
