Hi,all

Iam trying to make a panorama inside where's little dark and has only one lamp. I have to use large exposure in order to make the place look brightness.As a result,the photo against the light is too bright,and can't see the light clearly.The photo here:

Can I do something to avoid this and make the light looks more beauty?

Any Suggestion is appreciate.

Regards.

That photo looks like it was taken with a fish eye lens?

The brightness range in your 360x180 scene is far too great to be fully captured with a single exposure setting. Blown highlights and/or blocked shadows are inevitable. Solutions are to supplement the lighting, or to take multiple shots with different exposures to capture highlights and shadows and then merge these in Photoshop or specialized HDR (High Dynamic Range) software such as Photomatix. Care is needed to avoid a flat, processed appearance. See:

Maybe you are expecting too much. A degree of over exposure around lights is not too objectionable. If you take RAW images, you can do quite a lot to drag detail out of the shadows if you expose to favour the highlights more. I don't know if you are using your fisheye images for QTVR panoramas, but I did this one with much the same problem using a single set of RAW images, all with the same exposure:

woo,great job! Because I have no idea of how to deal with the raw images, I am shooting in JPEG format before. I will have a try now.

Thanks so much
