Panoramics, PTGui (and maybe PS) color correction?

Hi, i tried out an older version of PTGui, liked it and finally got
around to getting it. Almost everything is great with this (newer)
version (v5.8.1) but something seemed missing, it dawned on me, this
version doesn't seem to have the "color correction" option?!

Am i just missing this option buried in a menu or is there now a better
way to make the color/contrast/brightness about the same across all the
pictures? I thought that maybe i could just output it to a .psd and
then use match color to balance the different pictures but it seems
that enblend doesn't "blend" the layers, only the final product layer.

Any help suggestions (other than all the manual settings i should be
able to set on my camera [at the moment i have a fairly
non-full-featured point and shoot]) would really be appreciated!

Cheers

It can only do so much. If your images exposures are really far apart it as
I said can only do so much. You can use plug-ins with it so trying something
like emblend or maybe its enblend.

Your best bet to no have this problem is to set your camera of full auto and
take a reading of the most neutral lighted part of the scene (nothing really
dark, nothing really bright), make a note of the shutter and aperture the
camera indicates and then switch to manual mode and set those numbers. Then
shoot all of your images for the panorama will be evenly lit.

With others panoramatools-based apps, it is achieved via enblend
http://enblend.sourceforge.net/ but that does not seem implemented in
PTGui? Enblend can also work on a multi-TIFF output.

Alternatively, have a look at hugin http://hugin.sourceforge.net/ or
PTAssembler http://www.tawbaware.com/ptasmblr.htm if you need those...

Ok, i figured it out. For future reference all of those options are
still there but #1 only if you install PanoramaTools and only if you
select panoramastitcher in the "create panorama" tab. Apparently things
like color corection and morph-to-fit were not native PTGui options.

PTGui can use enblend. It works as a plug-in and simply needs to be setup in
the preferences section. Simple and easy.

Yep, I had installed that thinking i needed it but turns out that in
the newer versions PTGui can do that itself, not only that but with the
default settings PTGui seems to do a better job (though i did not try
modifying the enblend settings/options, so maybe with some tweaking
enblend would be better).

Try to solve the exposure issues before the stitching for best results.
