I need the data distortion/correction information for the
TAMRON SP 90mm F2.8 Di MACRO 1:1.
I’m doing museum archival photography, where I need to convert the pixel size into the real-life size of insects on images. There is a formula to this but it needs the distortion and the focus/scale distance data of the lens.
I’ve checked with Tamron, and they said Adobe Camera Raw has a file already all we need is to get all the data about the lens.
it seems that you guys are experts at this kind of thing and Adobe just didn’t help at all to help me to extract or locate the file I need to finish the math formula.
Can anybody help me with this?
Thanks a lot, I really need this data!!!
Pixls.us is for FOSS and not targeting unfree software like Adobe. With that said the folder Adobe profiles are in is:
If you want to use Lensfun, then Mica already pointed to the database. Keep in mind that for Lensfun the distortion correction is created at some distance, for example a target 10 meters away. If your purpose is to take close up pictures of insects you may want to take new distortion correction samples at the distance you will use, for example 30-60 cm.
