Photoshop skills needed for VR

I will admit that I am lousy at Photoshop, and it's ever increasing feature set
makes my head hurt. What are the essential tools/commands you would suggest
a panorama photographer working in PS. I'll start: crop tool!

Panotools plugin: Adjust
Submitted by Aldo Hoeben on Fri, 2006-08-11 21:09.I use the panotools Adjust plugin extensively while editing my panos for extracting rectilinear views of the zenith and nadir.
I hardly ever use the crop tool working with panos though (all panos I do are 360x180)...

Could you elaborate on how you use Adjust plugin for extracting rectilinear views of the zenith and nadir?
Thanks.
Tricky bit
Submitted by Aldo Hoeben on Wed, 2006-08-16 21:25.The tricky bit is to calculate the width and height of the cubic tile you need to extract.
Using the calculators on http://www.worldserver.com/turk/quicktimevr/panores.html, I first calculate the 'Angular resolution' of my panorama, and then see what cube face size has the same resolution in one of the later calculators ('Pixels Needed for a Given Angular Resolution').
In my case I always stitch to 8200x4100 pixels. Using the 'Resolution of a Given Panorama' calculator results in an angular resolution of 22.8 (pixels per degree). Filling in that value in the 'Pixels Needed for a Given Angular Resolution' calculator gives me 2614 pixels for 'Cubic'. I round that to 2650, and extract a 2650x2650 pixel, 90 degree HFOV image out of the panorama at tilt 90/-90. After editing, all you do is switch to insert instead of extract.
What I do is basically the same as PTeditor, only within Photoshop, and without the interactive view (so without the chance to mess things up).
I find I use a lot of the
Submitted by Robert C. Fisher on Mon, 2006-08-14 07:51.I find I use a lot of the funtions in Photoshop. A lot of masking, color correction, match color and even had the occasion to use HDR Merge for a job I had shootingVRs for a TV commercial. My PS skills have expanded a lot in the last 18 months or so and my results have also improved.

I have a ton of actions for every task I do a lot of, like open, close & save for converting RAW images to tiffs and others for centering before stitching etc., etc. I love HDR for Dummies (PS action) by Jook Leung these days. It saves so much time! and the results are good and adjustable!
Now I need to program a couple of f-keys for things like flatten and masking, things I do a lot of when editing.
I went to Maui on a job and I have been stitching my panos in between getting a new G5 system online. One addition to Photoshop that's just awsome is my new 24" Apple Cinema Display, I have been working on a 15" Viewsonics LCD screen for almost 5 years so this is such a great change for stitching and image editing. Now I'm looking for an inexpensive 19" LCD for tool pallets so my image can streatch out on the entire width of the screen. The only downside is that the screen is too large for fullscreen panos, they look better smaller actualy.

Try Select, Color Range and Image, Adjust, Levels.
You can select the Dark area of the image and Adjust the Levels without lightening the light and medium areas. Great for pulling detail out of a dark wood piece of furniture without blowing out the windows

Submitted by Sam Rohn on Sun, 2007-03-18 20:03.Photoshop CS2's Vanishing Point (Filter>Vanishing Point...) is indispensable for fixing
patterned areas which are in a non straight on perspective - think "perspective cloning"...

Re: Adobe Photoshop, Curves
Submitted by Doug Aurand on Mon, 2007-03-19 16:48.I've just recently figured out to apply Curves.
It works really well to bring the details out of the shadows without washing out the brite areas of the image
On Photoshop 5.5 I open a stitched Cubic Strip or Equirectangular Projection, then select Image, Adjust, Curves.
In the lower, left part of the grid, I move the Dark part of the image up from 20 to 30 and bring the Bright part of the image back down (the move from 20 to 30 moves the whole Curve up) to where it was origanlly, usually moving it back down to 191
