Technical input needed


Recommended Posts

Hi there,

I am as you'll no doubt be able to tell by reading this , a newbie to digital cameras, and recently bought a second hand Sony zv-1 to start filing some bits on. I've noticed that when it's a bit bright, not massively bright , but bright that parts of the image seem to be unviewable by the camera and are blocked out with a stripy mass. I've attached a picture to illustrate what I mean. Can anyone explain to me what the problem is and if there is a solution or not ?

I do apologise if this post is in the wrong place or the camera isn't part of the parameters, like I said I'm a bit green to this at the moment! Thanks in advance for any feedback / F :)

What these so-called 'zebra stripes' mean is that in the areas where they show up, the image is overexposed (or close to, depending on your settings). Overexposure means the photosites are saturated and the camera can no longer differentiate between lighter and darker areas. In post-processing you'll see that the overexposed areas are just pure flat white. When turning down the exposure, these areas stay 'flat', you won't be able to recover gradations or highlights.

You can disable zebra stripes in the menu if you don't care about all this and just find them distracting.

    • I mostly see posterization artifacts, which are the result of lossy compressed RAW files (or bad jpeg conversion). Unfortunately, the A6400 doesn't offer uncompressed or lossless compressed RAW. The noise might indeed result from the smaller sensor than what you're used to. If you're not shooting at max aperture, you could try shooting at wider aperture and lower ISO. When you're not shooting at max aperture, fullframe versus APS-C shouldn't matter much in terms of ISO-performance combined with depth of field: at the same ISO and aperture value, fullframe offers better noise performance but with a narrower depth of field. This can be offset by choosing a larger aperture and lower ISO on the APS-C camera. If you want a fullframe camera the size of an A6400, try the A7C(ii).
    • ..unfortunately, the lighting was correct. The shot required deeper shadows. The K1 ff didnt have these banding issues [yes, I know the sensor is larger]. The film shots had details in the same light. The sony files, both the jpg and raw, had this banding/noise - with NO retouch or post adjustments [straight out of the camera]. the camera was purchased new a few years ago and I am trying to determine if there is something wrong, or the settings are wrong, or the camera just cant handle this kind of lighting [studio + softbox]. No shadow detail is one thing... banding/noise in the shadows is unacceptable. Does sony have a body this size that is FF ? Im wondering if that would make a difference..  dw
    • The root causes for banding are uneven lighting, incorrect exposure settings, or compression artefacts or certain kinds of artificial lighting, especially LED lights. Also the lens used plays a role, I have noticed it more with my sharpest lenses, looks like they outresolve the sensor when I have a uniform blue sky. There is more than one solution, and ultimately post-processing, but the root cause has to be identified first.
