[Lensfun-users] Shift Lens Support

2018-04-03 Thread Robin Kramer
Is there any support for lenses with movements. I'm especially interested in shift. I have a lens with a shift adapter. When I load the straight image, the hugin gui calibrates the lens just fine, but when I load the shifted calibration chart images(all with the same movement), it seems to han

Hi All, I found that I can use RawTherapee which provides flat field correction, so that solves this problem. On 3/31/2018 8:08 PM, junkyardspar...@yepmail.net wrote: On Sat, Mar 31, 2018, at 14:05, Robin Kramer wrote: Hi All, I joined this list to ask about how best to calculate

Why don't you just use the calibrate_lens_gui.exe executable from the hugin suite. I find the interface is very nice. You kind of have to read between the lines to figure out which parameters are which, but its still easier than installing and running python and modules. I wish there had been
