Worms and Topaz De-Noise

I have good results removing worms with Topaz De-Noise on auto settings. I am shooting RAF from a XT-30 in LR Classic 9.2. I have a couple of questions

1. Why do I get artefacts in about half my RAF files only?

2. If it is a RAF processing issue, why do I see it in jpegs too?

3. Has anybody else tried the Topaz De-Noise editing.

Finally, I have no connection whatsoever with Topaz

thanks

I know of a X-Trans worm effect that may be what you're referring to.  Maybe 5 pixels long, with a L at the end, and hundreds of them.  I usually see it at 50% zoom, and always at 100% zoom, more noticeable at high sensitivity.  In my experience X-Trans produces more natural looking lines [than Bayer] at 25% zoom and less (and seems to do better at geometric designs, e.g.: tiny b&w lines), but Bayer seems to do better cropped in to 100% zoom (and at natural curves).  Not sure if this is what you're referring to, but handling them is very raw software dependent.  As for Topaz's software, I haven't used it.  Maybe you could attach some small screenshots or samples of what you're experiencing, and then someone will be able to answer?

attached an example off google (from dpreview's forums) about x-trans vs bayer.  two nearly identical cameras, but the clearer one on the right is x-trans.

actually it's simply because adobe still doesn't implement the de-mosaicing algorithm for fujifilm's x-trans filter .capture one ,luminar etc. has implemented it , so is topaz ,so that's why topaz software's able to provide a good image output from fujifilm x-trans sensor camera's . that's the reason why the output from all adobe software's not good for fujifilm x-trans sensor camera raw files .x-trans filter array is new and the advantages is you get sharper images , the next advantage is that the grains at higher iso from camera is similar to film camera's rather than digital camera grains . so if adobe decide to implement the de-mosaicing algorithm ,you'll no longer get any worms ,until then you can try another method , open up the raw file in capture one or luminar or topaz products ,and then convert it into DNG or TIFF , then you can work with it in adobe software's without seeing any worm effects . i hope this helped . have a nice day !

It actually does. To avoid re-writing the all system and keep retro compatibility, they manage X-trans sensors through the "Enhance details" function, for RAW pictures. You have to enable that (it will create a new .dng image) and reduce Sharpening to zero to see the worms disappear and finally have a great starting point for your editing.

enhance detail is only a workaround  ,if c1 , luminar , topaz ,darkroom etc , can do it without any extra steps ,adobe could if they wanted . they simply aren't doing it ,many users found out that reducing sharpness while importing to lightroom fix the issue , so if adobe wanted they can fix this pretty easily . have a nice day ahead !

      Hello. Thankyou,now Is all more clear: I have take some time in your link. Let tell you. I has totaly forget this machine have "compress picture option" and not Only "compress lossless" anyway not change the experiment. RAW  and this last two format look like same result about Number of recording picture. Can tell all results in this: in raw you can make 17 pictures for second. Is wrong. Is about One single Press and wait buffer. Full 30/20/10/8 not change. After 17 Need Press again. You not can Press before "redgreen light recording Is on".   With preshot you can have 25  are more 7 pictures . The story change Only in jpg shot only. In jpg at 30 you have 30 picture but redgreen light off very Fast so you can shot very quicly. At 20 shot Is about start look like infinite shot. 60. So the best performance are this last One  about Speed and recording picture after camera working witout big limit. I want take a shot about Italy cyclet Just for passion. I think i Will use this last setting.  After Need check when battery not are full change and ambient temp.  Anyway my cam look like exactly specific about you link. Im Happy my cam working perfectly.

      I do not use Flickr, so I do not know what their BB code is. All I did was copy the second link you provided, (starting at https: and ending at  _k.jpg — leave off the [img] and [/img] tags) and pasted it into the message. After a moment, a message popped up asking if I wanted to paste it as the image or as a plain link. I did this twice, the first time I had it paste in as the image and the second time as a link. Nothing fancy or tricky.

      So do I just copy the BB code from flickr and paste it anywhere on the page like other forums or is there some other trick I need to perform to get it to post?

      X Raw Studio Doesn't Create Drive for Camera When Connected

      All software is the latest between camera and app. All settings are correct on camera. I have both lossless and uncompressed RAW files on the card in the camera. I have been up and down every reddit thread to no avail and am losing my mind… I’m doing all of the right things. It even sees my camera. It just doesn’t create the “drive” for it (see attached image screenshot).  Please Help!
