I settled down with Irident X-transformer with these settings:

RAW process : more detailed

sharpening:none

Luminance noise reduction: Low

Color noise reduction : medium

Dng baseline : adobe default

Apply all corrections to the image. (all checked)

All the turn off lightroom checkboxes checked.

 

as for sharpening and further noise reduction I use NeatImage ( a Photoshop add-on)

Capture One is the best overall solution. Seems you're figuring that out. Dump Adobe.

your post intrigued me because of the use of the word "worms" in that it described exactly what I saw when I took some images of some archways at a local mosque. The archways are white plaster, nothing more. But when I got the images home, at 100% in LR the images seemed to consist of, well, little worms. I tried to clear it up and submit an image to a stock agency and it was rejected for artifacts. That never happens to me. Ever. So, am I suffering from the Fuji v Adobe issue. 

 

I wish I could upload an image to show you but I'm not at home right now.

here's what I mean. This was shot at ISO 100 and has +38 Clarity applied.

Hi,

I have used several X-trans cameras. I have at present the XT-2. Regarding the worms effect on foliage etc have you compared the out of camera Jpeg to your raw file?. I have always found some sort of worming effect on small leaves and foliage is present with my out of camera jpegs ( using default settings ). I find that the Acros simulation shows this up really well. I am beginning to think that it is a quirk of the Fujifilm Xtrans sensor perhaps. The "worms" are also present with my little X30 too. 

Cheer ian.

I know this is an old topic. But i wanted to tell you guys how to avoid wormy artifacts in Lightroom. 

Under sharpening leave the "detail" slider at 0. Thats it. No wormy artifacts. No need to change your whole workflow...

Dumping Adobe for Capture One? Such nonsense. Learn to use the tools right and Adobe LR and PS produce stunning results.

Bottom line learn what it is you are working with - that is an Xtrans sensor vs a Bayer sensor.  Fuji files are created with an Xtrans sensor which is quite sharper than a file created with a Bayer sensor.  Therefore default settings in Lightroom tend to over-sharpen when translating from the RAW format; thus creating worms.  This can be proven by simply over-sharpening any image - you will get the same effect.

I use a preset while importing to my Lightroom Catalog that sets all sharpening to 0, then as Capture One does, I increase the Noise Reduction to 50.  This provides an imported image to work with no different than if it came from a Bayer sensor or if I was in Capture One. 

Lately the "Go To" solution has been to use Capture One, but if you look at the default import settings it simply decreases sharpening and adds Noise Reduction to remove the worms.  Truth is both Lightroom and Capture One are both great software solutions, they simply handle Bayer & Xtrans sensors files a bit differently so you need to adjust accordingly.

The discussion on this topic is as old as the X-Trans sensor itself. It is now a well-established fact that Capture One and Silkypix Developer Studio offer the best approach to read out the correct sensor data, unless you only use Fujifilm X RAW Studio. You can certainly get good results in Adobe LR too, but the handling of the X-Trans sensor is different than in the three converters mentioned.

      pocket wizard and XT5?

      By LBAbrams · Posted

      Has anyone successfully used pocket wizards with an XT5? I cannot get it to fire.  Do Fujis and pocket wizards get along? Thanks in advance for your wisdom on this, kind readers!

      Grzegorz, Go to the Networking Setting in your camera menu (the last one at the bottom - unless you have a My Menu then that is the last one). There, go to Network Setting and choose the SSID (name) of your WiFi network, type in the password, choose "SET". If you have a functioning DHCP server on your network, the camera should get its IP address (and Subnet_Mask and Gateway). If not, you can enter these manually. It is a little tricky, there will be some zeros already here, move the cursor after the zero and use DEL to delete it and make space in the input fields for your own correct values. If you do not know what to enter, have a look at values in the network settings of your computer and use the same except for the IP address, try some fairly higher number, hopefully you hit an unused one. Usually the values would be something like IP: 192.168.1.188, Subnet Mask: 255.255.255.0, Gateway IP: 192.168.1.1  or something like that, take clues from your computer. The camera and computer must be on the same network. Then in Connection Mode on the camera, choose Wireless Tethering Fixed. And half-press the shutter to exit the menu and get in shooting mode. The red LED should be blinking. If you can look at your network devices, e.g. on your router, you should see the camera there. You can see check the camera settings in the camera menu in the INFORMATION item of the Network Setting menu to see the MAC address of your camera and look for it in the list of devices on your network.  Then use the tethering in your software, e.g. in Capture One. The camera may not show immediately, take a shot and then it should show in the list of available cameras. Good luck. Report back how did you fare.  PS If you have a Windows machine, you need to have Bonjour installed and running. Macs have it.

      X-T30 II Eye Sensor + LCD Image Display viewmode not working

      By grizzski · Posted

      Hey all, I just got my first camera. The X-T30 II. It seems the Eye Sensor + LCD Image Display view-mode is doing the exact same thing as just the Eye Sensor view-mode setting. Any ideas why this is or what's supposed to be happening? Firmware Version: 2.04

      Problem with multi exposure on XT5

      By George_P · Posted

      What GordW said. You have to put the drive mode dial to "S" - Single Frame. If you have it on CL, CH, BKT or Panorama (or HDR), the Multiple Exposure option will be greyed out in the shootng menu. On my X-T5 it works in RAW + JPG and also in JPG only. When Multiple Exposure is switched on, the image quality cannot be set to RAW only. If it was set to RAW only before switching Multiple Exposure On, image quality defaults to RAW+Fine. The result is JPG. After each shot press MENU/OK and after the last one press DISP/BACK.
