Broad yellow bands in X-Pro2 jpegs


Recommended Posts

I've owned my X-Pro2 for a couple of weeks with no obvious problems, until a few days when I did a shoot in a room with high windows lit by the evening sun. I shot on this occasion entirely in jpeg, with a 56mm f1.2 R lens fitted. Most of the shots were fine, but a number showed broad, diffuse yellowish bands in them. At first I thought these were shadows or reflections in the room, but on closer examination I am convinced they are in-camera artefacts. In landscape-format shots the bands are horizontal, in portrait-format they are vertical, which confirms my suspicion. Has anyone else experienced this, or have any ideas what might cause it?

 

Thanks

Just seen the same banding in an X-T1 forum topic, there it was cause by combining the electronic shutter with fluorescent light. In this case I suspect the LED's were 'dimmed' - meaning that they are flickering on and off at a high frequency which would cause the banding.

Nothing wrong with your camera, just the frequency of the flicker of the lighting clashing with the capture speed of your sensor in electronic shutter mode. If you had been shooting a video at the time, you'd be able to watch the lines move and wiggle. In video, you fix it by changing your shutter speed to match the frequency of the lights. In photos, you can change over to mechanical shutter and that should solve it (though you're not silent anymore, obviously)

    • Because the sensor assembly is moved electrmagnetically. When there is no power it is essentially free moving.
    • Hi everyone I have a problem while using my xpro3 and strobes, from a day to an other I started to have a black shade on the side of my ID photos so it's kind of problematic. It's like if the speed is to high except it happened even at 1/30s. And the shutter speed seems accurate with ambiant light so I'm a bit disturbed about all of this.   Anyone has an idea about that case ?

      This is the equivalent of 43 minutes, 40 seconds of exposure. NGC 1502 is a neat little cluster located in the Camelopardalis Constellation. This region of space was thought to be fairly empty by early astronomers, but as you can see, there is a lot there. Kemble's Cascade (a.k.a. Kemble 1) is named for Father Lucian Kemble, a Canadian Franciscan friar who wrote about it to Walter Scott Houston, an author for the Sky And Telescope magazine. Houston named the asterism for Fr. Kemble and the name "stuck". NGC 1501 is the Oyster Nebula. A longer focal length telescope is needed to bring this one into good viewing range, but it is well worth the effort.
