Canon 17-40mm and panoramas - how?

I just recieved a phone call from an other photographer who asked me if I could help him with an assignment. He want to take the shots for a panorama with his canon camera and a 17-40mm lense. He wants me to stitch them and publish them as panoramas.
He is only interested in the horisontal view, and do not care about looking up and down.
I tried to advice him that he should let a professional panorama photographer do it, but he want to do it him self. Normally I would say no, but he is interested in 50-100 panoramas, so it is a big assignment and a good opportunity to make a little money.

Now I have to advice him how to approach the job. He does not have a rotator - just a normal tripod. Is it possible for him to shoot the pictures I can turn in to a panorama? If so how many pictures should he take?? Will I be able to stitch with panoweaver? Or should they just be assembled in PS?

Please any advice will be highly appreciated.
Best regards
Morten

Hi Morton,  You did not mention which Canon camera - so I will assume he his not using the full sensor sized 5d.  I hope he is only wanting to take OUTSIDE panoramas.  Since he does not have a pan head probably means he will put the camera on a pan-tilt head on his tripod in Landscape orientation.

Means that the crop factor is probably 1.6  and his 17-40mm really is same as 27 - 64mm.

Outside imaging taken at 17mm (35mm = 27mm) you would need to have at least 30% image overlap.

Panoweaver will not stitch his images because it works only with Fisheye lens images.  You will need to use alternate stitching software.

You might consider using photoshop | automate | Photomerge.

Hi Dave

No that is one of the rediculous to. He want shoot small cottages. Once again I have adviced him that he should let a panorama photographer do it. But he insist. Hopefully I can get him to buy a panohead if he gets the job.

At the panoguide forum someone said that he would propably need to tage 10-12 images for one panorama.

I have given him a price where I estimate that Ill be using  1- 1 1/2 hours stitching every panorama. I hope that is enough.

Best regards

Well,  one way is to just show him.  Using a real pan head, camera and 17-40mm lens set at 17mm,  set up in a small room space. Say 3m x 3m.  Then let him look through the view finder.  At 17mm the bottom of the image will be at least 8ft or 3 meters from the tripod center.  Meaning you need to be using a VERY wide angle lens taken with camera in PORTRAIT orientation.  With camera in landscape the vertical field of view will be VERY short.

I used to make cylindrical panos with a similar setup - You will do best with a rotator with 12 stops - correct NPP is essential
