Hello NN members,
Just want to know what your settings are for focus on your lenses.
Even if I shoot at a small aperture (F11~F16) I just want to know if you have lens focus set to infinity.
Is that right?
I have shot various panoramas now but when converting to vtours, I notice that the images are still sharp but do not retain that crispy sharpness I want.
Last but not least, I use Krpano for making my panoramas. I'm not sure if that has anything to do with the sharpness quality but for those who are familiar with KRPano I have tried multires mode but I still don't get that sharpness that I want. Maybe it's my focus afterall???
Looking to hear some comments about this.
Thanks for reading!
You can use hyperfocal distance to get to know when your lens is sharp from form set focus to infinity.
Here's a list I made for Nikon FX Bodies: http://ge.tt/23P2qVq/v/0
You can make your own list for your camera. Seal it and take it with you going out for shooting. I've made the same sealed card for my settings.
Reading your message it looks like sharpness issue is not in shooting process but more in stitching/publishing process of your panos. I would advise to keep best resolution all the time. My own process is:
-> Shoot in RAW
-> Derawtise with your preferred software: Lightroom, Aperture, Darktable... and save as TIFF 16 bits full resolution
-> Stitch with your preferred stitching software: PTGui, Autopano among the bests, and save as TIFF 16 bits full resolution or if file is too large as PSB file
-> Use of the droplets included with KRPano to generate a multi-tile panoramas giving him the PSB file and you should get best resolution possible.
Let me know how it goes ;)
Also keep in mind that smaller apertures can cause diffraction which decreases sharpness. It varies lens to lens, but most lenses are sharpest around F8.
My Nikkor 16mm actually tests (using FoCal software) as sharpest at F5.6.
Yes... thanks for the workflow. I notice that the sharpness is decreased when converting the stitched image into a vtour. I will try your suggestions. Thank you. I would also like to thank mosleyh and hidenhaag for the helpful input.
