that's averaging. for star trails/light painting maybe you'd want the brightest pixel (and for removal of stuff median etc). that said it'll be simple enough to add a couple of different blending modes to dt's merging code (at least those that work pairwise such as max(), median may be more tricky). -jo > > > On Tue, Feb 28, 2017, at 21:57, darkta...@911networks.com wrote: >> DT 2.2.3 on arch. >> >> I took photos of a car at night and did some light painting with an >> LED in 25 seconds blocks. >> >> I have 9 images with each image a different area of the car lit by >> the LED.
