Dear forum members,
Here's the recent shooting of me and a friend of mine in a 16 m yacht...A very challenging VT for us with big differences of light "falling onto the different parts of the pano" in very narrow rooms...Any input for improvement is as always very welcome -especially on this work here as we are hoping to be active commercially on this way...3-bracketed shots on a Canon5d mark2 - if I knew I'd shoot one day HDR panos I'd buy a Nikon at the beginning , enfused in enfuse GUI...

Burak,
Nice camera shaped instrument right in the middle of the helm.
I can also see your tripod leg shadows. You are getting much better at covering them up.
Your whites are still just a bit bright in a couple of images.
Shooting Raw you should be able to pull out 3 images to blend. Bracketing 3 RAW shots is even better. With 3 RAW images, you should be able to pull out whatever bracketed set you want. Your Canon should do just fine.
When I "pixel peep" I see this:
You should be able to mask out one of the two images. The shadows on the carpet show that the sun moved from the first image to the Nadir patch. That can be difficult to get right. Sometimes a whole lot of post processing is needed to get the shadows to look right. If you are going to allow zooming, you need to get these details right.
Small spaces uncover any rig calibration errors. Looks like your rig is spot on. All those small rooms are not for the faint of heart! Good job.
Nice looking panos. Lots of crisp sharp details. The colors are not over saturated. Good job on the interiors right next to the windows. No blown out windows.
You should be very proud of this set. Very nice.
Dennis

Dennis thank you very much..I think (hope) my rig is good calibrated now, with your help and with the help of the tutorials of Smooth and John...I shot 3 bracketed images in Raw...The reason for the problem by the curtain is; there was wind and when one merges 3 bracket images, it comes out like this, the same can be viewed also by the flags etc...What I still couldn't/cannot solve to my satisfaction is the bottom with shadows and stitching errors in the corridor/in the kitchen...I had it at different shootings by now...When the floor is like this patching in Photoshop doesn't help much...These repeating patterns on the carpet are difficult to patch, copy etc...I am shooting nadir with nadir adapter, I know just how many cm. I have to move my tripod away from the shooting point to become a nadir without a hole (which can be caused by the overlapping of the third leg of the tripod with the nadir area)...But this, apparently is not always enough for a ground without shadows...Ok, of course there is a solution...We have the viewpoint correction in PTGUI so I can push the tripod more sidewards "loose the NPP", just shoot a nadir shot at for example -45 which covers the whole nadir area without any shadows and then use viewpoint correction...But I have made the experince that this brings worse stitching results then when I shoot very closed to the NPP...So this set was also shot with nadir adapter and just away enough form the origial shooting place to get a floor with no "hole"...Viewpoint correction is a tool to help but it seems to have its limits...
Thanks for the encouraging comments...
Regards
Burak

Patching the Nadir and removing all shadows can be very difficult. You can see why some people take the easy way out and put a mirror ball or very large logo at the bottom just to cover up the tripod. That is cheating.
Sometimes I have to modify the individual images in Photoshop prior to stitching. I have been know to warp and twist an image that just does not line up. That is where the real time preview in PTGui really comes in handy. I sometimes move the shadow in the Nadir Patch shot prior to stitching in order to make it line up with the side shots. You can bring in the patch shot more than once. This will allow you to line up sections one at a time. You mask out parts that do not line up. There is no rule that states have to use just 1 patch shot. In this pano I brought in the Nadir patch shot 3 times. Being so close to the rail, I could not get a good stitch. www.dlsphoto.net/Hawaii2012/Room/Porch/index.htm
You can offset your camera at a 45 degree angle and use Viewpoint Correction. John has a good tutorial www.johnhpanos.com/ptgvpt.htm As long as the surfaces are flat, this is the way to go.
Removing the shadow from the helm will take probably as long as the rest of the process will. In the end, the result will be more than worth the effort. I have spent upwards of 8 hours just patching out shadows and such just to get the Nadir to blend in.
Don't be afraid to slide your tripod over further than the calculated distance when using the Nadir adapter. You need to develop different techniques for patching the Nadir when you use a camera position way off the NPP. I will rotate the entire rig around 180 degrees in order to capture additional shadow free images. Remember that you are trying to create the illusion that the pano was taken in one shot. The more techniques you have, the more difficult shots you can do.
As to the curtain, edit the picture prior to stitching. Take your blended image with the error, find another image that has what you want it to look like, bring them both into Photoshop and manually combine the images prior to stitching.
This is a hand held pano I did at Disney Paris. There is about 12 hours of Photoshop touch up work done after stitching. The result was worth all the time. www.dlsphoto.net/Europe2009/Paris/Disney/Inside_C...
It can take so very much work but the resulting pano will be worth it.
Dennis

Dennis thank you very much for all the information...I'll see how I will handle the nadir in my workflow...I don't like logopatch on the floor either, it is something that "doesn't belong" to the panorama...Good quality work must be without it...
