Grungy backgrounds

14 black grungy backgrounds, most of light coming of reflection and bump, 7k hi res background (not tileable, yet), the effect is very subtle, but tested on my few monitors an mobiles, just about right amount of black, looks great as a monitor wallpaper, instead of having complete black or grey

ZIP files of .jpg 5 mb per image, or .png 32 bit 100+ mb per file, 2,8 gb total - some are up to 10k extremely hi res and hi quality
