Is there an application within Aperture 3 to defish a fisheye photo? I searched in Aperture "Help" but no results came up. I tried downloading Defish 2.1.1 but that only resulted in getting a text file of gibberish. Please pardon my lack of knowledge, it is because I am brand new to Mac OS.X and my new Mac Book.

Thank you for any help you can provide.


Mac Book, Mac OS X (10.6.6)

    Welcome to the list. Make sure you read the [Help & Terms of Use|http://discussions.apple.com/help.jspa] section when you get a chance.

    No way to do that in Aperture, you'll need a plugin or eternal editor. I'm not aware of any, not something I've ever needed to do. Don't know anything about Defish but I found this [link|http://wiki.panotools.org/DeFish] which may help.

    I use and recommend the [PTLens plug-in|http://epaperpress.com/ptlens] for Aperture. It is regularly recommended for defishing. (I use for rectilinear lens correction and perspective alterations. I don't have a fisheye lens.)

    Thank you for your response and the link to PT Lens. That is exactly the type of program/plug-in I was looking for.

    Again, thank you!

    Just looking around at how people would defish a fisheye in Aperture - thinking of adding a Samyang lens to M4/3 gear to get that ultrawide image but having seen Kirby's link to PT Lens when that corrects you have to crop a lot of the image out get rid of the background which has been revealed.


    Please for give the really dumb / stupid / rookie question but is this the same for all barrel correction software - I know LR has lens corrections does that do the same thing? If so they this looks like a great way to get into nice clean wide angle pictues - just bearing in mind you'll have to crop some of it away to get the nice clean lines.


    Thanks James

    Also check to see if the particular lens vendor has software made for the specific lens.

    Yes.  Defishing deforms the image so that straight contours (e.g.: edges of objects) in the scene recorded appear straight in the image, and then trims everything outside the largest rectangle that can be cut from the deformed image.


    I'll repeat the good advice that Kurt Munger has posted on his site (iirc): Use rectilinear lenses for rectilinear results, and use fish-eye lenses for their particular, but non-normative, rendering of the scene.


    Fwiw, I've heard very good things about Samyang's MFT fish-eye.  And although I sold my MFT body, I kept the Panasonic 7-14 lens.  It's expensive, but well worth it if you want ultra-wide-angle.

    Thank you Kirby for the response - I've actually gone for the Olympus 9-18mm almost-ultra-wide as a compromise. It's nowhere near as expensive as the Panny 7-14mm, takes filters and at the zoom end works well as a 35mm street shooting lens as well. I've still downloaded the PT Lens trial and it seems to work really well for those wide angle shots which are not perfectly straight so putting walls back vertically again.
