Is my GR sensor faulty ?

[Ridethelight]

Purchased the GR yesterday,love it,just got the Jpegs settings just right,but I have noticed strange curved lines and areas of sky that almost looked rubbed out.

Look above the trees

Could this be the auto DR function ? I will cont to play around.

Any ideas ?

Stop shooting JPG, it's the automatic JPG setting causing this.

Looks like JPG compression is causing banding. This is why you should never shoot JPG only. Unless it's an emergency, it's just not worth it.

Wow are you sure about that,I shoot Jpegs with Olympus and Fuji and never saw this before.

Here is another one with contrast and brightness adjusted to show slightly more.

The first image looks ok but here something is wrong.

Too much JPEG compression?

 

[timtop]

Don't listen to the RAW snobs - this isn't JPEG compression, and not the type of artefacts you'd get if it was. (this type of banding would normally appear in formats such as a 128 colour .gif or similar where a gradient is being compressed by using only a limited number of colours). I'd suggest a faulty camera or (possibly more likely) the image processing software you're using. Do you have any more details about your workflow after the file is downloaded?

There was a thread about a month or so back, if you do a forum search, you'll find it and the answers your seeking.

Titled: Concentric circles in underexposed areas sensor problem.

my first reaction was welcome to the club...

but not quite so!

the concentric circles appear in underexposed areas of the image. in your case it is the sky, and i am not sure what's happening with your camera?

could you try a raw file too, to see what's happening there...

this is strange.

I've had the GR for a few weeks and have had this issue on one over-exposed shot below:

The rings might not be very apparent on the image (but are on my computer) so adjusting the contrast and shadows gives this:






It was shot as jpeg only at F16, 1/40s, ISO1600, exposure compensation +0.3, flash on, soft sharpness, auto WB and, as far as I can remember, soft vignetting. I think noise reduction and dynamic range were both off. The histogram shows huge pixel peaks at the top end, as you'd expect.

I've not noticed the rings on any other of my shots.

Is this one of those 'not real world' examples (although I do actually quite like the over-exposed effect of the original) or is it something more sinister?

Hi,

are you processing the jpeg or the raw file, as you mention "shot as jpeg only"? The GR gives 8 bit jpegs, which gives 256 tones to lump the colours into. The raw files are 12 bit and so give over 4,000 tones and would give you better grading. So if you want to overexpose and then adjust in processing shoot raw+jpeg and work on the raw files if you need to.

cheers Al

I'm having a similar problem with mine.

This is a B&W High Contrast SOOC Jpeg. The RAW file doesn't show the anomaly, so I don't think it is the sensor. I believe the problem is with the Jpeg processing engine:

Well, that's good news, then it should be fixable with future FW-updates. On the other hand I would never buy the GR for solely jpeg-shooting. The WB and colors does not to come out the way I wan't them to. I definately would prefer a Fujifilm-camera for jpegs only (the X100 which I used to have or the X100S). However I never shoot only jpeg and for RAW the GR seems almost unbeatable (I am having trouble finding the sharpness of the GR at any lens-combination with my Nikon D7100). And, of course, the size/weight and handling are quite unique.

Thanks, Raw it is from now on.

I just experienced the problem described on this thread. i have a bunch of ruined sky pictures...the camera has the latest firmware. I had the camera set to "orig" vs "normal", which was supposed to deal with the concentric circles issue...

my pictures, just like the one shown above, does not have the heavily shadowed areas, but just bright cloudless sky. Very annoyed.

any input most welcomed.
