Better quality

Hi all, I have a question from my photographer;

Q: Is there any way to maximise image quality of a KR pano 360° spherical pano movie to match the Pano as viewed in photoshop?



I am currently creating 360° panos with an 8mm using Canon mkII1ds. 4 images are captured as raw and processed in Capture one 4 pro. Tiff files are then stitched with PTGui pro.

This ends up as a 6394 x 3182 px file at 300ppi File size =57.9 mb.( Looks great as a inkjet print at 53 x 26cm)



In photoshop the images are crisp and colours are rich and just as I want them- however when published in KR pano the image resolution is degraded and colours are flattened slightly. Can anyone help with any suggestions to my dilemma?

Thanks

Hi,

about colors - try using sRGB,

and about sharpness:
- what krpano version (1.0.7 or 1.0.8)
- what kind of panoramic image (spherical, cubical)
(and if cubical - how/with which tool have you converted it?)
- what jpeg settings (jpegquality, jpegsubsamp)

are you using?

best regards,
Klaus

Hi,

the settings are okay,

but with:

Zitat von »designsubway«

jpegquality=100
jpegsubsamp=444
you can get very large jpeg files!
but there should be no problem with sharpness...

you can post a link where you have a problem?

best regards,
Klaus

designsubway, if you are using professional camera and printing I guess you are working in wider color profile than sRGB. In my workflow I export tiff files from Lightroom in Adobe RGB profile, stiching them in PTGUI and convert final stiched images into sRGB (in Photoshop Edit->Convert to Profile...). This helps to preserve colors in panorama and web browsers that don't support color profiles.

Sorry, Klaus *huh* didn't see your post about colors.
