spikemozeley Posted June 6, 2017 Share #1 Posted June 6, 2017 Advertisement (gone after registration) Hi friends, Today I noticed something I havnt seen before. In live view when half pressing for exposure preview if the image is under exposed I'm seeing these unusual horizontal stripes. Thankfully they are not appearing on the photographs, but I'm curious on any thoughts. It's kind of distracting. I would add an example image but can't see how to upload file... 1 Quote Link to post Share on other sites More sharing options...
Advertisement Posted June 6, 2017 Posted June 6, 2017 Hi spikemozeley, Take a look here Live View Exposure Preview. I'm sure you'll find what you were looking for!

jaapv Posted June 6, 2017 Share #3 Posted June 6, 2017 The bottom (and top) arrow button toggles the display of framing guide lines. Quote Link to post Share on other sites More sharing options...

spikemozeley Posted June 6, 2017 Author Share #5 Posted June 6, 2017 The bottom (and top) arrow button toggles the display of framing guide lines. Thanks for the reply. Unfortunately that is not what I mean. It almost looks more like some kind of broad banding. Quote Link to post Share on other sites More sharing options...
lct Posted June 6, 2017 Share #6 Posted June 6, 2017 (edited) Were you shooting at high iso? Edited June 6, 2017 by lct Quote Link to post Share on other sites More sharing options...
spikemozeley Posted June 6, 2017 Author Share #7 Posted June 6, 2017 Advertisement (gone after registration) I was shooting at 1000 ISO I believe Quote Link to post Share on other sites More sharing options...
lct Posted June 6, 2017 Share #8 Posted June 6, 2017 Not enough to explain banding i guess, unless you underexposed by more than 5 or 6 stops. Quote Link to post Share on other sites More sharing options...

pop Posted June 6, 2017 Share #11 Posted June 6, 2017 What kind of lighting? Incandescent, LED, fluorescent? The good people here need at least a little bit of information for offering you their guesses. 2 Quote Link to post Share on other sites More sharing options...
jaapv Posted June 6, 2017 Share #12 Posted June 6, 2017 Yes, I see where you are coming from, Philipp, but that could never explain the phenomenon happening on the LCD and not on the image. It must be some internal problem in the camera. 1 Quote Link to post Share on other sites More sharing options...
spikemozeley Posted June 7, 2017 Author Share #13 Posted June 7, 2017 I have just done a test in natural light and it doesn't seem to happen. I tested again under flourescent light and it is showing up big time. This time the strips are dark green. Still not showing up on image file though....

Exodies Posted June 7, 2017 Share #14 Posted June 7, 2017 Does it show up when you look at the LCD or only when you photograph the LCD? Quote Link to post Share on other sites More sharing options...
pop Posted June 7, 2017 Share #15 Posted June 7, 2017 Yes, I see where you are coming from, Philipp, but that could never explain the phenomenon happening on the LCD and not on the image. It must be some internal problem in the camera. The LCDs on some of my cameras behave unexpectedly with artificial lighting. I can't say I have seen stripes like these, so far, but badly flickering displays are no novelty. Quote Link to post Share on other sites More sharing options...
spikemozeley Posted June 7, 2017 Author Share #16 Posted June 7, 2017 I just tried this again on a different body. In low light it is doing the same striping on both cameras. This happens in Live view with exposure Preview. Surprised I never noticed this until recently. Quote Link to post Share on other sites More sharing options...

This time the strips are dark green. Still not showing up on image file though.... In that case Philipp is right and you seeing a stroboscopic representation of the pulsing of the fluorescent light. I just tried and mine does exactly the same. I never noticed in all these years It appears there is nothing wrong with your camera. Sorry for the second-rate phone shot. Welcome, dear visitor!

Reeray Posted June 7, 2017 Share #18 Posted June 7, 2017 ^ that's exactly what's happening. If it's any consolation I can see such an effect on all my digital cameras. Now, you say it doesn't show on the image. I bet it does. Take a few shots in quick succession and view them on a computer screen. You'll inverably see a difference in colour amongst the set and the bands will be apparent. Nothing to worry about. Just a fact of light effect.

jaapv Posted June 7, 2017 Share #19 Posted June 7, 2017 That will depend entirely on the shutter time and the moment of the cycle that the image is taken. The Live View has a fixed refresh rate. Quote Link to post Share on other sites More sharing options...
