Adobe Lens profile per Fuji XF 18-55

XF 18-55

Image courtesy Fujifilm.eu

Uso la Fuji X-E1 con l’ottimo 18-55 2.8-4 da ormai 2 settimane e ne sono pienamente soddisfatto come avete potuto leggere nel mio precedente post. Nonostante la eccellente qualità dei jpg generati dalla fotocamera, mi trovo comunque spesso nella condizione di preferire i file RAW (a dire il vero scatto sempre in RAW+Jpg Fine…) e tutti sanno il mediocre supporto di Adobe nei confronti dei file prodotti dalla linea di fotocamere fuji con sensore X-Trans.

Nonostante non possa di sicuro migliorare i risultati della de-mosaicizzazione, una cosa che ho potuto e voluto fare è la creazione di un profilo per la correzione delle distorsioni dell’obiettivo in questione (l’unico che possiedo, per ora, della piccola X-E1).

La realizzazione del profilo avviene tramite una procedura non difficile ma un po’  lunga e noiosa utilizzando lo splendido software messo a disposizione da Adobe, adobe lens profile creator, scaricabile qui  per PC e qui per Mac ; e comprensivo di una esaustiva guida d’uso (in inglese)

Ho seguito le indicazioni di Adobe e rendo disponibile pubblicamente il profilo, facendo presente che non garantisco i risultati, nonostante lo abbia provato in varie situazioni di scatto e mi pare svolgere bene il suo lavoro. Le foto sono tutte fatte a f11 quindi, la correzione della vignettatura e delle aberrazioni cromatiche può non essere sufficiente per tutte le casistiche. E’ stato effettuato montando l’obiettivo su una XE-1 e non so dire se possa essere efficace anche per la X-Pro1 (anche se non vedo perchè non dovrebbe). Una volta scaricato il file, per essere utilizzabile da Lightroom, è sufficiente inserirlo nella cartella (per Windows) che si trova nella posizione C:\Program Files\Adobe\Adobe Photoshop Lightroom 4.3\Resources\LensProfiles\1.0\Fujifilm\ (assumendo che quello è il percorso in cui avete installato Lightroom)

Fatto ciò, riavviate Lightroom e attivate la correzione lente nel modulo sviluppo.

    Well interesting that you did this but totally unnecessary as the lens correction is already done by Adobe automatically. The lens correction information is stored by Fuji in the EXIF and Adobe reads and applies that automatically that is why there is no profile in camera raw or lightrooom. This is per Eric Chan the Adobe engineer who implemented the raw conversion. His interview is available on the Luminous Landscape web site for a small few. He explains there why some mirrorless cameras like the Fuji and Olympus have built in lens correction information.

      Hi Alan,
      thank you for sharing this interesting piece of information. I decided to create this profile because when I searched for one in Adobe’s Lens Profile Downloader there was no profile for the zoom lens but there were for all the three fixed focals: 18, 35 and 60 mm. So I figured it was because the zoom (and the 14mm) are relatively new. I didn’t know about the EXIF storing lens correction infos. Neveretheless after what you told me I removed the profile and exported a couple of jpgs with lens correction on (no profile included), and again re installed my profile and re-exported the same file (buildings with corners near the picture’s margins shot at 18mm) and I do see a clear difference in the two results. (plus vignette is also very clear).
      I’m not sure what is going on here, but if you happen to own the Fuji and the zoom lens just try it with a “critical” situation so that you can tell me if I’m doing something wrong. (Is there a possibility that my Lightroom doesn’t read the Exif stored infos? Is it possible that exif infos are “general” ?)

      Thank you again.

    I like to use it in LR, but I tried also in PS only for check. I also deleted an other file from this folder and after this the delete profile is away. I think I am in the right folder. Hmm very strange. thanks for your response.

      If you are on a 64 bit system try the “programa files (x86)” folder

  5. looks 17 febbraio 2013 at 15:00 #

    I put the file in the folder LensProfiles\1.0\fujifilm But i can’t see the file in LR 4.3. I am using win7 64bit, not txt only lcp. I tried in other folders like canon and also in the CameraRaw folder to use with PS, but no way to see this file.
    @oflr: for you it work now?
    I hope you can help me, thanks. Looks

      Hmmm, I’m sorry this is complicated… I think it depends whether you want to use it with Camera Raw (hence Photoshop) or Lightroom. I’ll try to check on Adobe’s help page if I find more infos…

      Hello Ofir,
      Assuming you installed Lightroom in the standard windows position, you should put the file you downloaded in the following folder:

      C:\Program Files\Adobe\Adobe Photoshop Lightroom 4.2\Resources\LensProfiles\1.0\Fujifilm

      Make sure the file extension is .lcp (some users said they had .txt added…) and that Lightroom IS NOT running while you copy this. Then, just relaunch LR and voilà :D
      Hope this helped, have a nice Sunday

    Hi Neil,
    thanks for trying it out.
    Another user had the same problem with .txt being added at the end of the file, he also was on a Mac, so I suppose it probably is some sort of precaution used by Safari when downloading an unknown file type?
    As for the profile not appearing: I really don’t know. Make sure Lightroom is NOT running when you copy the file, and also, try to put the profile inside Library/Application Support/Adobe/Lightroom/resources/LensProfile/1.0/Fujifilm. I am honestly just making an educated guess because I’m on a PC so I can’t check files and folders locations.

    Let me know!

  9. Neil 16 febbraio 2013 at 23:09 #

    Thanks for this. When I looked at the file it had a type .lcp.txt so I renamed to .lcp which seems to be the standard.
    It also had an extra line at the top and the bottom which I removed, and then it looked similar to other profile files.
    However, when I added it (on OSX) to Library/Application Support/Adobe/Camera Raw/LensProfiles/1.0/Fujifilm the profile still wasn’t recognised by Lightroom.
    Any suggestions?

    You’re welcome! Thanks for passing by.
