Default Fixing exposure and whiter balance.

Hi everybody and thanks for a very helpfull forum

I have been taking pictures to sticht together to a panorama.
unfortunately was the white balance and exposure on auto.
I know it must be on the manual but not then.
Is there a way to correct the images so they get the same white balance and exposure?
I have taken them in RAW and I know you can do it fairly manuel mode in ps4. But is there a way where you can correct many images at once ?
I will really appreciate your help :-)

Sorry to say there isn't a way to do a batch correction, unless they need the same amount, which I guess they don't otherwise you could stitch them. Is there a consistent point in all the photos that you can use as your guide?

You're welcome.

OK, so in your situation you have snow so hopefully this is pretty consistent in colour so you can use it as your guide for setting the white balance (assuming the snow is in all of the photos). So correct your first one then use that as the guide and then correct each of the others so the 'white' of the snow looks the same. It's easier than using a total photo and trying to work out the WB.

I don't use PS so can't go into detail (hopefully someone can) but usually with most progs you can have one photo open and be manipulating another one, this will allow you to match the two. You could just go B&W and the only need to worry about exposure

The Adobe Camera Raw has, IIRC, a way to set WB by using an eyedropper on a section of the picture, so that should work to set one of the shots. If the light changed enough for the auto WB setting to give you different results, though, you probably don't want to do that on every picture. Instead, look at the results of the first setting, in terms of color temperature and tint, then set your subsequent shots to the same value manually. This should give you consistent WB for all your pictures.

However, if the light changed enough to affect the auto WB, it may have also affected the exposure, so you may need to do some adjusting of that as well, in order to get consistent results for a pano.
