Hi there, i hope someone can help me

I have just started researching on virtual tours, i have the equipment and photographed one house.

I have to take 6 photos at 60 degree, when i stitch the photos in panoweaver it works fine, but sometimes you can easily tell where the photo has been stiched.

Can someone please advise me on the correct apeture settings and shutter speed to get rid of blown out windows etc..

Or any tips to help me out would be much appreciated..

I am using a Panasonic DMC FZ8, Raynox DCR 5000 Wide angle lens and a manfrotto tripod..

SHOOT RAW!
Av mode...f/8...bracket exposures at -2 0 +2.

By bracketing your shots you will end up with an underexposed, normal exposed and overexposed images. A lot of us here use photomatix to then merge these three images into one, which will correct the issues of blown windows.

There are other ways to achieve this as well.

So here is mine:
I shoot 3 around at 120 degrees in RAW and in manual mode. Each shot I will bracket, I take one shot each at 0EV, +1EV, +2EV, -1EV and -2EV. I then take the 15 images and convert them to jpg and batch stitch in Panoweaver5. Then I put the 5 stitched scenes in Photomatix http://www.hdrsoft.com/download.html and merge. There are several different ways to merge the images you will just have to play with them and find the results you like best. You can download the free trial and try it before you purchase. With this method you will have no blown-out windows and the lights will no be glaring. From there I take it into photoshop and do the fine tuning to my taste. I also shoot my still shots this way except I merge them in RAW and then convert to .tif and rework in Photoshop before converting to jpg.
Here is a sample I just completed using this method.

-------------
Nikon D300, D3s, Nikon 10.5 lens, RingT105N+Footplate+MrotatorTCPs, Giottos MT9261 Tripod, Manfrotto 410 Jr geared head.

If you know the "secret" then everyday is a good day!

I doubt the couch is that colour. I feel it is a result of the HDR method.

Regards, Smooth

maybe reducing the saturation [desaturate] a little bit might make the red couch 'glow' a little bit less.

Believe it or not that is very close to the color of the couch. But the question still remains, Shmo wants to know how to get rid of blown-out windows!

HDR can create some odd color effects. Using Photoshop's Hue & Saturation then from the drop down go to and reduce Red. This could make a very acceptable result if you were to want to reduce the red in the couch. Tweeks with the other colors is also usually necessary. Certainly (in my opinion) all worth the trade off for correctly exposed windows.
