Leicauser7 Posted February 15, 2017 Share #1 Posted February 15, 2017 Advertisement (gone after registration) The above behavior just started, seems maybe to correspond with the firmware update, but maybe not... has anyone else experienced this? I would describe it as dark and light horizontal bands within the LV image. Everything is fine during playback. Images seem to come out normally. ?? Seems to have only in certain rooms (all with artificial light)... in some its quite bad and in others it seems to go away. Maybe this is normal behavior with certain artificial (LED?) lights? Thanks. Link to post Share on other sites More sharing options...
Advertisement Posted February 15, 2017 Posted February 15, 2017 Hi Leicauser7, Take a look here M10 LV Horizontal Banding?. I'm sure you'll find what you were looking for!
digitalfx Posted February 15, 2017 Share #2 Posted February 15, 2017 would need a lot more info to be helpful. is it all conditions? ISO what kind of lighting screen capture of issue Link to post Share on other sites More sharing options...
Cliff S Posted February 15, 2017 Share #3 Posted February 15, 2017 Was it at extremely low exposure? Link to post Share on other sites More sharing options...
Leicauser7 Posted February 15, 2017 Author Share #4 Posted February 15, 2017 hmm... it seems to be certain rooms only, particularly ones that have lower Led lighting with cream colored walls... happens especially when I point the camera at a plain uniform cream colored wall... get two dark bands running through the LV... again, has no impact on the captured image... very weird... i've tried with a couple of different lenses and i'm in auto ISO..

Leicauser7 Posted February 15, 2017 Author Share #5 Posted February 15, 2017 Doesn't seem to matter what ISO is set and i've tried different screen brightnesses and that doesn't seem to matter either. Link to post Share on other sites More sharing options...
Leicauser7 Posted February 15, 2017 Author Share #6 Posted February 15, 2017 I've also noticed that sometimes... though not all times... when i pull up the menu the display brightness will vary from set intensity and then will drop for a second and then come back... a bit subtle clearly happening... seems like maybe the electronics in the camera are messed up somewhere?

digitalfx Posted February 15, 2017 Share #7 Posted February 15, 2017 Advertisement (gone after registration) Certain types of lights cause this. It has to do with the refresh rate. Not unique to Leica, happens with all cameras Sent from my iPhone using Tapatalk Pro Link to post Share on other sites More sharing options...
Leicauser7 Posted February 15, 2017 Author Share #8 Posted February 15, 2017 so you think my camera is likely fine? Link to post Share on other sites More sharing options...

Leicauser7 Posted February 15, 2017 Author Share #10 Posted February 15, 2017 thanks! I will sleep better knowing so As always, the help you all provide on this forum is beyond words and I am very grateful.... thank you again. Link to post Share on other sites More sharing options...
digitalfx Posted February 15, 2017 Share #11 Posted February 15, 2017 The flickering issue is caused by the the light source To our eye they look like they are constantly on, but actually the light is flickering at the frequency of the power supply, 60Hhz in the US, 50 Hhz in Europe The video display or live view refresh rate is syncing up with the pulsing of the lights, causing the interference or banding you are seeing. You should also notice that it changes with shutter speed. Link to post Share on other sites More sharing options...
Leicauser7 Posted February 15, 2017 Author Share #12 Posted February 15, 2017 Thanks. That all makes sense to me except the last statement. The shutter speed is just a setting that has no bearing on the LV right except for the "moment" that the image is captured. so how wold the setting on the shutter speed dial have any effect on the phenomenon that you are rightly describing? Thx Link to post Share on other sites More sharing options...

Thx yea sorry that later part refers to screen on a video camera...I copied that from a reply I posted earlier on another forum asking about the same issue on a digital video camera. Changing the cameras frame rate between 24/30/60 fps will affect the strobing. Link to post Share on other sites More sharing options...
FrankX Posted February 15, 2017 Share #14 Posted February 15, 2017 Unfortunately, many light sources show this flickering. Unfortunately most modern LED lamps! By the way, this not only influences live view but also your final images!!! On your images you probably won't see any banding, but overall exposure can vary depending on shutter time. As long as the shutter time covers a full or at least half of a cycle (1/50s or 1/100s at 50 Hz), you won't see a problem, but a shorter shutter times there is definitely a big problem sometimes... Just another challenge for us photographers. But we love challenges, don't we @Leicauser7: Your camera is fine! :-) Link to post Share on other sites More sharing options...

I've seen this too, on FW 1.0.2.0. I haven't updated yet. Link to post Share on other sites More sharing options...
Leicauser7 Posted February 15, 2017 Author Share #16 Posted February 15, 2017 Thanks again -- to be clear, you are talking about changing the video cameras frame rate... there is no such option for the m10 LV correct? Link to post Share on other sites More sharing options...
