Koisam Posted February 27, 2017 Share #1 Posted February 27, 2017 Advertisement (gone after registration) Hello my friends! I am new to the forum and had just bought my new Leica q Titanium gray last week! Liking it a lot... great outdoor photos! However there is a banding issue that's worrying me: Has anyone has problem of or experienced horizontal banding when the shutter speeds go up to 1/2000s or faster (the electronic shutter mode)? Shooting a coral fish tank, I set the ISO to 6400 thinking of capturing sharper images of the swimming fish with a faster shutter. However I got some very noticeable bandings on the photos. These happened at speed 1/2000s, 1/2500, 1/4000 with the few photos that I shot. Are these banding due to my technique problem? wrong settings? the lighting of this particular coral fish tank? the fault in my Q? Any suggestions or comments are welcome!

Advertisement Posted February 27, 2017 Posted February 27, 2017 Hi Koisam, Take a look here My brand new Leica Q has horizontal bands on photos at 1/2000s. I'm sure you'll find what you were looking for!
Koisam Posted February 27, 2017 Author Share #2 Posted February 27, 2017 The first attachment: iso 6400, f 4.0, 1/2000s The 2nd: iso 6400, f 4.0, 1/1250 Link to post Share on other sites More sharing options...
pop Posted February 27, 2017 Share #3 Posted February 27, 2017 I would suspect the tank lighting. Is it some kind of LED lighting driven at a rather high electrical frequency? Link to post Share on other sites More sharing options...
jmschuh Posted February 27, 2017 Share #4 Posted February 27, 2017 It´s the frequency of the light.... You should use the mechanical shutter. Are there any reasons for shooting fishes with 1/2000 or shorter? New gene optimized Turbo-Rocket-Fishes? 1/60 to 1/250 should be okay for fishes and you can use a lower ISO speed for a better photo quality. Link to post Share on other sites More sharing options...
Koisam Posted February 27, 2017 Author Share #5 Posted February 27, 2017 Yes I think it was the Led light causing the banding. I was a kind of testing the iso and shorter speed than1/2000, that's why I pushed up the iso and wondering how fast could the fish swim! Though the fish swam very fast, my photos of 1/500 & 1/1250 gave very sharp photo. I am very impressed by the Q. Just now I 'tested' the shutter speed of 1/2500 under fluorescent light in my room, I can see some banding again in the photos. This time it is wider and less pronounced. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! So is it normal to have some bandings in the photos when we use the electronic shutter in the Q (or any camera) under indoor lighting (fluorescent or led)? Would there be situations when we have to use 1/2000s or shorter speed e.g.. indoor athletic, diving, car racing etc..?

Echo63 Posted February 27, 2017 Share #6 Posted February 27, 2017 as others have said, It is likely to be PWM or a similar flickering on the tank lights, flickering at around 44,000hz (22 lines x 2000 = 44000 cycles per second) it will likely go away at a lower shutter speed, maybe even just dropping to 1/1000 will get rid of it.

Voxen Posted February 27, 2017 Share #7 Posted February 27, 2017 Advertisement (gone after registration) Nothing to worry about. Electronic shutter just doesn't work with some artificial lights, as the one in your fish tank, and even with strobes. Link to post Share on other sites More sharing options...
