This came up on a Spirit-thread where I spoke about having a straightforward workflow for color-matching while there are still sequences that are just plain difficult to match.
Color-brightness matching can be fun. I have probably a dozen ways of attacking the frames, depending on the look and the variety among them for a given panoramic sequence.
I'd like to hear from others how they approach this. I'm handling it primarily as an artist. I rely on my eyes and go for Photoshop. Open the sequence, look for the biggest differences, determine similarity for a big part of the images and then divide the bunch in two or three sets. First I correct the brightness levels by changing the input-output levels via 'levels' in PS. Then I check for color-values in different frames and start by altering the R,G,B levels separately.
For certain pans I made the pan first using PTgui and saving it as a .psd file.
I have found this to be slightly more difficult since you are very dependent on a few frames to adjust all other frames to.
I sometimes also change the brightness values to the grayscale single frames before assembling into color.
What I would like to get to is a routine that works for all sequences since some of them are difficult to match mad.gif
Anyway, time for bed now but tomorrow I'll continue.

What software do you use dilo? I might look into updating some kind of tutorial on my site but right now I got a few pans awaiting some stitching smile.gif

Hi Nico... I know relatively well PaintShopPro and, for this reason, I usually use it; only recently I started to use Photoshop (but I have an old version) and sometime other shareware programs (like PhotoLine32).
PS: Thank you very much to Nirgal! wink.gif
