When using your camera to determin the expsure (shutter speed and F-Stop) for locking in the exposure manually where do you take this metering from to determin the best exposure to lock in to manual mode. Do you meter for the bightest area of the panorama knowing that the darker areas will be under exposed but easier to correct or do you meter for the darkest area knowing that the lighter areas will be more likely to blow out and harder to fix?

I would think you would take an exposure reading or the lightest area that will be in the panorama knowing it that is easier to correct under exposure (even if you have to use a noise recduction plug-in).

The reason I am asking is I have a Manfrotto 303SPH panoramic head and a set of legs coming and I want to start doing the panoramas seriously which means taking an exposure reading and locking that in to manual.

The way I have generally done this, is to meter from several different areas to get a feel for the best exposure, then err slightly for the highlights and if time permits, bracket.

One I did last week - not the best, but 6 or 7 pictures joined. A bit of flare towards the right, but I only popped out for an hour or so.

Thanks. I have started to use the exposure compensation function more and have by default shooting about 1/2 stop under-exposed. I will try the bracketing.

The panorama you posted looks nice. I like the flare area, makes the sky a little more interesting. Though if it was most of the sky that wouldn't be good but the little that there is a nice effect.

You can always pull out the shadows, but blown highlights are gone forever! Shoot in RAW!

Obviously the wider the range, the more susseptible it will be to exposure, so i't's best to keep the exposure locked to the central position of the panorama.

Other things to watch out for are movements during the panoramic sequence i.e. people, masts on yachts, etc.

The attached panorama were all taken hand held & stitched using Smoky City's Panorama Factory which works well. I've had to tweak each shot to eliminate problems referred to above. The resultant shots have been reduced in size both in terms of memory & pixel size.

you obviously have a pano head and how to use it. one thing not mentioned here is to use a custom white balance because on auto WB , it'll change for each shot. i usually meter at a midway exposure.i made a pano head out of some 1/4'' aluminum stock i had laying around.
