affinota Posted June 6, 2023 Author Posted June 6, 2023 thanks, but I don't understand for sure. Is it just the part of lensfun and not really a part of affinity photo and I have to wait or make correction by myself? Quote
walt.farrell Posted June 6, 2023 Posted June 6, 2023 It is supplied by the Lensfun team, and used by Affinity Photo. Once it is in their released databases, Serif will incorporate it into Photo. If Lensfun already has the information in their database, but have not officially released it yet, you can extract an XML file from their database and add it to Photo. If Lensfun does not have the information, you can ask them to develop it. Or you can follow their instructions and create the information yourself. You can then add it into your copy of Photo, and you can contribute it to Lensfun so they can offer it to everyone.

Stun Damage Posted June 6, 2023 Posted June 6, 2023 While you wait for support, take the time to manually correct the distortion in one of your photos. Don't use mesh warp, just tweak the sliders in the optics panel of develop persona. Be meticulous about it, then write the numbers down. They will be the same for all your shots with this lens. From here on out, you just type them. You can do the same for vignetting. Create an overlay, paint the corners of your picture and bring the exposure up until they match the rest. This number is also consistent, once you've got it right you can just mask the corners and type it in the exposure slider. Quote
Pšenda Posted June 6, 2023 Posted June 6, 2023 4 minutes ago, Stun Damage said: take the time to manually correct the distortion in one of your photos Since the lens in question is a zoom (not fixed/single focus), you would have to do this for all focal lengths. Then, according to the specific photo (focal length used), apply the measured correction parameters of the relevant focal length. That's quite a lot of work 🙂 Stun Damage 1 Quote Affinity Store (MSI/EXE): Affinity Suite (ADe, APh, APu) 2.5.7.2948 (Retail) Dell OptiPlex 7060, i5-8500 3.00 GHz, 16 GB, Intel UHD Graphics 630, Dell P2417H 1920 x 1080, Windows 11 Pro, Version 24H2, Build 26100.2605.

Then again, a few millimeters in length hardly make for a noticeable difference in distortion. It'd probably be sufficient to work in increments of 10 and profile 30, 40, etc. Still fiddly, but better than waiting for support. And vignetting will still be a fixed value regardless of focal length. If anything, it's affected by the aperture being wide open and can require a bit stronger exposure compensation then, but even that mostly happens with cheap lenses, not sure whether that's the case here.

There is a moderate amount of vignette (+55 to correct). 50mm... while the vignette diminishes (+41 to correct). 75mm .... while vignette is slightly less (+37 to correct).

Charly06 Posted March 5, 2024 Posted March 5, 2024 Hi Everyone, an update regarding this lens profile, it is now available in the lensfun github portal. https://github.com/lensfun/lensfun/blob/master/data/db/mil-tamron.xml I updated affinity lens profile with the tamron profile file and the lens is now automatically recognized. Cheers, Charly Quote
