advice needed on blending the sky

by harryshin » Wed Nov 14, 2012 1:43 am

hi:

1. i'm going to assume this is a very common question, but if someone can help me out, i'd really appreciate it.

2. basic data: i shoot in raw, process all images with the same parameters, shoot in manual (same exposure etc...). most of the time, the default blending in autopano or realviz (autodesk) works perfectly. however, i'm currently dealing with an image that was shot fairly wide (24mm full frame equivalent) and was shot in harsh contrasty lighting and is a very long pano (ie about 360 degrees). thus the sky isn't as blended smoothly as i would like.

3. question: in very concrete steps, how would one go about dealing the above situation?
3a: i read the current documentation re: multiblend settings (using that sliding bar) and frankly i still don't understand if a negative value, 0, or a positive value will help the situation.
3b: i'm not sure if anchoring a specific image would help the situation or methods in that regard.


thanks in advance for any advice. harry shin

if the problem is dark "bands" you should try to remove vignetting before stitching.

you can use lens correction parameter in Camera Raw that will detetc lens used and adjust vignetting and distortion which cna be quite useful. Also pull down blending to -1/ -2 should smooth out the sky a bit too
