Scanning Horizon Panorama pics with Vuescan/Nikon coolscan 5000ED

[Roel]

Hope i can get some help with my scanning. I just got back my first roll from the Horizon Panoramacamera (2X35mm wide). I use the latest Vuescan with my Nikon coolscan 5000ed.

Basicly i am trying to scan 2 scans for 1 wide picture and want to stitch them together.

My problem is that i can't get even exposure and color/whitebalance with this setup.

How can I tell Vuescan to stop measuring the second image (second half of the picture) and use the setting of the first scan (1st half of the picture). I can't get the colors and brightness to match.

Input | Lock film base color

This option locks the color of the film substrate to values calculated at the most recent preview or scan. These values are displayed in the "Color | Film base color" fields when this option is set.
Negative film has an orange tone that needs to be compensated for to produce the positive image. You can see this orange color by looking at an unexposed (clear) area of developed negative film.
For a given film type and roll of film (all of which is developed under the same conditions), this correction will be the same for all frames, so only needs to be set once.
This option is only available after Input | Lock exposure is set, and then after a preview or scan.
This option can save time when scanning a batch of images with similar characteristics, e.g. a roll of film.

Input | Lock image color

This option locks the black and white point used in the most recent preview or scan. This is useful after scanning the first image of a series and you want to make the lighting consistent in future scans (especially when scanning panoramas). This option is only displayed if you first set the Input | Lock exposure option and the Input | Lock film base color option.

Lock exposure, scan to RAW.
Stitch 2 RAW scans. Invert.

(you can use Vuescan's scan from disk/file to get stitched file back into Vuescan and invert it there).

Thanx guys for the tips. Looks like i did something wrong with the exposure locking but now it works!

Now just trying to figure out what the best/fast way is to select the positions for the scans. My trail and error took me a long time and still havent found the standard way to select the positioning of the two scans that match the whole panorama picture.
