X-T2 artifacs when shooting backlight

Hi all,

I read about those previously but I never experienced in such a strong way. Can any of you advise how to deal with this? (both in postprocessing and/or shooting future sessions). Please zoom 100% into her hair, for instance. The texture, like a canvas pattern, is terrible. It is not a random gaussian noise at all or the classical weird effect due to oversharpening in postprocessing! No, it is NOT a lightroom issue. You can see the artifact in the jpeg OOC (attached next) and in the RAF converted to DNG using Iridient X-Transformer.

What can I do??? And please do not tell me to not shoot like this. It is a style that in the sunny Mallorca the clients are really demanding.

Thanks in advance for your help

This is one of the reasons I'm switching to an X-T3. I shoot towards the sun quite often and I also tend to get the red grid flare :( It's an annoying and ugly issue that's very difficult to fix in post.

To these dismissive responses, I beg to differ. In my experience shooting with Fuji, as much of an advocate against pixel-peeping, this type of grid artifact I'd extremely noticeable. It's present in the camera jpg, and no processing I've used (in Adobe ACR/LR) can circumvent it.

It is visible and distracting, non stop. Lucky for me my income does not depend on delivering photographs, but for those that do, this is indeed a problem and not something to sweep under the rug

I haven't run into at all with the XT-2. If I was shooting in a situation that I thought I would run into it, I'd go with the XT-20 instead - known not to have the problem. Professionals always have a back-up plan.

It is easily reproducible in the X-T20, as I've shown in my replies above in this thread. It's debatable whether the effect has been reduced or not, but it certainly still can happen with the X-T20.

In any event, every pro review I've seen has indicated that you literally have to get the angle just right to see the issue... and all the photos I've seen with it would look horrible with that sun angle whether or not the purple flare was there. I suspect a slower lens would have handle the terrible flare in that shot much better, in any event.

Finally, it is a LR problem. The sliders in ACR/LR are very crude, and that's just one of the reasons why so many folks have gone to more precise raw converters that can desaturate a very narrow slice of the color spectrum. This would be an easy fix in Capture One.

Using any filter on the lens potentially adds to the problem, because the flat rear glass of the filter will reflect light back towards the sensor more.

There's a reason most lenses have curved out elements.

So as a rule of thumb, don't shoot into light with a filter on the lens.

It is my understanding that changes were made to the XT2 around the time the XT20 came out that improved the situation. I have a newer XT2 that I shot right next to a guy with an early production XT2 , he was having purple grid issues and we tried, but couldn’t get mine to exhibit the problem - he had an 18-55, I had a16-55 (don’t know if that’s relevant). I’ve never seen the purple grid on either my XT2 or XT20 and I shoot into the sun and bright stage lights all the time.

Yikes, which camera is that from ?
Click to expand...
X100s

The presence is not the same as the flare related issue but the appearance and pattern is similar

Weird, at 1/10000s it would be an e-shutter, does it happen with the mechanical shutter as well or with the e-shutter at slower speeds ?

I have the xtrans 2 with the X70 and I've never seen anything like that but then I don't use the e-shutter often.

So generally speaking FUJI X-T3 incurs minimal purple flare when pointed directly at sun. Sometimes my X-T2 produces star-bursts when pointed directly at sun so results mixed; for better or worse. X-T2 still represents big leap forwards from X-T1 so no chance of me exchanging for X-T3 for the sake of it. Maybe consider new X-H2 with image stabilizer.

X-T2 no longer on sale in Europe or USA?
 
I have a post XT20 model and have never seen this effect. There was a suggestion Fuji changed the baffle after the XT20 was released and it stopped this happening.

I wonder if there’s a way to find out if a person has an affected of fixed X-T2?

After all is said and done and your photo is hanging on the wall, no one is going to know or care what camera, lens, or what post processing you used. All they care about is if the image moves them.
 
Just compared shots taken with my X-T2 w/16mm and A7 w/35mm; no big difference when pointing directly at the sun with blue skies here in France; both show star-burst.

But my experience of purple flare or color reflections happening on water surfaces in brilliant sunlight at certain angles. In all other respects X-T2 the gold standard. The new X-T3 slightly bigger and heavier; for me that matters.

Fuji UK advises LH XF16 metal lens hood for Fuji 16mm: Available in March.
 
My impression every camera has something not quite right; like cars. However it must be said the flare apparent with the photo of couple with sunlight in the distance is unacceptable for such an expensive camera. Any owner who feels disappointed should be given the option of favourable exchange for improved X-T3. Personally I would not bother. Shooting into the sun will usually cause flare; but purple reflections that's new.

Well, usually when you get flare it's the lens that causes it and then it's not in a grid pattern. I've never experienced any other camera/sensor causing any flare before I had my X-T2 :/

Other mirrorless cameras can do it too, the phenomena is related to the closer lens/sensor proximity. The older Fujis seem to be worse than most, though.

When I first purchased my X-T2 and read about this issue, I took it out and tried to replicate it. It was easy to replicate, I could see it in the viewfinder before I took the shot. I also noticed that if I changed the angle of the camera to the sun/light source, just a little bit, without changing my composition that I was able to take the shot without the purple artifacts.

So, to me, it's just a matter of understanding the limitations and capabilities of my equipment.

By the way, you have some great shots that you posted to this thread.

Special color (grid-stabilizer) filter to be made for X-T2? Or install new sensor: Capteur in French. We seem to be "captured" with badly-behaving Fuji sensor. Fuji aware; but in no rush to release any information to shine light on this subject; pun intended.

Reflections between lens surfaces and, or lens filter surfaces are primarily responsible for the grid pattern. The grid could be the micro-lens assembly or the phase-sensitive AF pixels.

The flare and ghosting are additional evidence that the exposure level for the bright, point source light source is well above the point where reflections become digitized. In other words the flare, ghosting and grid artifact levels are greater than the time-dependent noise levels.

I experienced significant flare and ghosting (including purple and green color streaks) with the Nikon D200, 300 and 700 using wide-angle zoom lenses ( 3 different Nikons and a Tokina). The X-T1 had less flare and ghosting with the XF 10-24/4. None of these displayed a structured grid artifacts.

One suggestion may be to give RawTherapee a try. The latest version is actually able to mix and match demosaicing algorithms based on local contrast of regions in an image. Solid/smooth areas are demosaiced in a way which reduces artifacts, particularly when it comes to sharpening. I would not be surprised if it solves this issue as well.

To get this, choose '3-pass+fast' as the demosaic method.
