Schott UG5 filter images taken on full-spectrum cameras:
Unlike the UG1, this filter has IR kicking in along side the UV producing less stark and dominated by violet, images. There will still be a need to hue-shift some of the violet over to blue and any smidgen of greens will be lost in reality, being 2 stops down. If you don’t mind stacking with a simple UV cut filter, some of the purple cast can be reduced.
Not a filler I use a lot as I prefer the images from a BG3 filter.
