I have the manual samyang 8mm fisheye....
In the new Autopano Giga 2.6.2 is possible to make HDR images also without exif data? If yes, how?
I also use the 8mm Samyang...
I do in most cases note on scene the values of F,aperture and exposure time used.
in autopano giga after loading/ importing the images BUT before the pano detection you can enter the image properties where you can set the values for your images.
you also can use such tools like exiftoolgui or exifpilot to edit/change the exif data for your images. So I also have the samyang 85mm and so the manual editing the hundrets of images would be rather a buddhist exercise, so in this case I edit one image and than copy & paste the values to the other images of the same f-stop.
and in almost all cases I do none of both above ways anymore, because I use my T&C handcontroller in combination with my promote control device. the promote control is creating the needed brackets for the HDR and overruling my Canons Operating System and so sending exif data from promote control device to camera (instead of from lens to camerabody) and the T&C handcontroller (the same as from panogear package) is writing the xml log for image positions
