Nice! I am downloading DxO software now. Thanks for any tips on leveling panos. I agree that mobile delivery of panos is of great importance.

I got information about new DxO Software:

www.dxo.com/us/photo/dxo_viewpoint/introduction

You can download a trial and test it.

Be careful as to why your purchasing DXO Viewpoint.
If you already have DXO optics you already have viewpoints features included as part of the program. The only reason to purchase Viewpoint as a separate program is if you want the convenience of opening the correction module directly from Lightroom or Photoshop as a plug in.

As far as I can tell you gain nothing more over the full DXO Optics program other than speed convenience as a plug-in.

Happy to be corrected if I'm wrong. The question has been asked many times on their forum with no company response.

I think you can change them manually if GUI doesn't allow it.

Treygaf, I think you need to apply some white balance correction to your images, which have a pronounced orange cast. This is best done in the RAW conversion. Your project file doesn't include any vertical line control points, so when you say you have levelled the panorama, maybe you did it visually. I've put my stitch and project file at:

www.johnhpanos.com/Archive-jh.zip

I tried to remove most of the orange cast. There are also big differences in the brightness and colour of the individual images, perhaps because you used auto settings on the camera. For levelling, I added two vertical line control points (tutorial at www.johnhpanos.com/levtut.htm if you need any guidance). The panohead at the nadir shows a sawtooth pattern, which suggests the lower rail setting on the panohead could be better.

Perhaps I went a little overboard on my "warm and cozy" coloring. I was trying to make the room look warmer, more inviting. Your effort does look more accurate.

Would it be possible for you to post a link to your .pts file so I can see where you placed the vertical CPs? As for the saw-toothing, I will double-check my setup. Thank you for your guidance it is always appreciated. And thanks for your tutorials.
