    I've tried to find a correction to the purple hue on the edges too but without any luck :( That would be a great fix, otherwise it's possible to post correct that in After Effects.

    A lens swap won't remove the problem, but will minimize the effect if the new lens has a narrower FOV i.e. the same can be accomplished by changing the camera setting from Super Wide or Wide to Narrow. Using Narrow will lessen the effect.

    Does anyone have the actual script that works on the older GoPros to fix the pink issue? I would like to look into making the mod for the newer GoPros.

    while we wait for a software solution for pink eye, here is an optical solution i use. a 2nd IR cut filter in front of the lens. the specific wavelength of the back-bone hero4 ir cut filters cancels out the colors that the lens profile is compensating for. this negates the pink and acts as an ND filter (between ND2 and ND4).

    i secure mine to the lens with heat shrink.

    thanks to frankycro on rcg for this wonderul solution

    the coating and the wavelength of the backbone filter is optimized for the hero4 optics. it may still work for the hero3 though.

    Yes those are the same. The price is better too.

    Any filter will degrade the optic's clarity to a certain %, even lens coatings that are being apply during the lens manufacturing causes a % of desegregation, but to a much smaller degree.
    A high quality lens/filter is highly recommended.

    All this being said, I think for our purpose "Arial Video" & the fact that the GP image censer Isn't the "Top of the Line" among image censers today, It's safe to say that applying a external filter to the GP will work, but just not ideal.

    Do Filters Affect the Resolution of Lenses?

    so just through away all of those ND filters?
    Sorry but i disagree, even on high end DSLRs filters are common in a pros bag

    Not at all, they will work!
    Just not a complete solution to the Pick Eye.
    I read most of the link that i posted in my last post & they tested many filters & came to the conclusion that only the best Filters offer less distortion "Very small" amount.

    LUT = Look Up Table ( Simply put: a configuration of colors ) Certainly not an adjustment layer. More akin to a sRGB, ProPhoto, Adobe 1998, etc.

    Just don't follow the internet tutorial that has you take the whole camera apart. It's a 10-15 minute job if you just take the outer lens collar off (it snaps off easily) then unscrew the lens. Screw the new lens in. The biggest part is getting an accurate focus (watching the focus through a HDMI connect monitor), then locking the lens where it is in focus I used a little piece of window-screen rubber between the lens and the lens collar.

    Hope that helps.

    Yes, true.
    But the "solution" don't comes for the GP3.
    The problem was not knew when some GP3 owner buy this lens and it was too late for a product return!
    For this reason, I dislike Peau Productions!
