Please can anyone help. I am new to panos and am having a problem when they are stitched together with colour differences. I can stitch them fine but there is always one shot that seems darker than the rest. I am aware that you need to have any main source of light at 90 degrees if you can so all the light isn't in any single shot. I am trying it out with two other people who are taking the shots. The equipment we have is:-nikon Coolpix 8700, fisheye lens, Mrotator B camera head with tripod. I seem to find conflicting ways of taking the shots. We are taking three 120 shots. I have read to keep the AE lock on; set the first shot up and only press the shutter halfway make a note of the settings and take all three at those settings, take each shot manually.... I am now totally confused. All three shots individually are good ones but I always have the colour difference. Is there a way of getting the shots right to start with or do you have to do something with them after they are stitched. I have read that you can do the latter in photoshop CS2. Can anyone clear the mist. Any help would be very much appreciated.

use AE lock and you shouldnt have a problem..
We use p* mode on the camera and AE lock and the exposure/colour is the same for all shots.

I too get results sometimes of different color temps with interior shots.
Setting white balance to white paper or gray card seems to fix the problem. I always card a sheet of bond paper in my case.
I use 5 shot bracketing and this method seems to rid of the color temp differences.
Thanks,

You use photomatrix or some other hdr software to combine the 5 photos of the same scene, then stitch them together.

I do not think the AE lock is best. I thought some cameras will actually change the aperture to maintain the exposure. I may have read and use myself the manual function and the proper white balance. By proper white balance I mean indoor outdoor sunny or shadow, anything but auto white balance.

Thanks for the replies. Could you explain what p* is and where do I find it? Are there other settings that I need to look at? I will try setting the white balance to white paper as suggested. Any further help greatly appreciated. It's so frustrating to be so near and yet not there yet.

I dont know your camera, but the situation is the same for all cameras. You must works with all controls in manual mode, also the white balance. In case that you cant do that or make some error, you only need that all your pictures has the same colour temperature in order to stitch your panorama . You can correct the color later in photoshop.
