Eyepiece Laser

Laser through the viewfinder works very well in the studio, I haven't had use for it outdoors yet, but I'll check brightness later.
No harm has come to my 5D2, and the laser has been left on unintentionally for extended periods.
I have mine mounted on a Canon eyepiece adapter and it pivots to point to any part of the frame, with adjustable friction so it stays where you point it.
I use it in product lighting to determine where to place flags.
I also use it with my tilt/shift lens to help focus /tilt adjustments.
It's a very good focus indicator.
I do turn it off before shooting, but I'm pretty sure that the ground glass breaks up the beam enough that it doesn't hurt AF and metering sensors.
During exposure, the mirror covers the ground glass, so I don't think there's any danger to the CMOS.
Two years on my 5D2 and everything still works fine.

Helicon Remote is now available for Mac as a beta. Works great for me.

Does anyone here have any experience doing a photo-wallpaper room?
I'd like to put one of my big spherical VR's to use by doing modified cube faces and having them put on walls, ceiling and floor.
Anyone ever seen such a room?

Near/Far stitching accuracy w/Fish-Eye

I gather, from reading here and elsewhere, that Fish-Eye lenses have differing NPPs from center to edge of the field of view, and that one must use a compromise setting.
I want to shoot from 16" above a table full of food, and have the food, as well as the infinity view sharp and free of stitch errors.
Canon 15 Fish Eye, of Sigma 14 rectilinear are my options, advice?

It's not the tripod. If you have centered the bubble on the NN, and the tripod is stable, and the bubble moves as you rotate the NN, there is either play in the rotator mechanism, or the bubble is not accurately aligned within the NN.
I read in another thread that as long as the bubble remains within the marked circle, you're OK.
As for tripod heads, try a geared head. Since getting one, my ball heads have been gathering dust. For anything you want to do precisely, a geared head is the way to go.

I strongly urge you to buy an AC powered display turntable, and (used) enlarger timer. Display turntables run at ~1-3 rpm, so a timer that lets you set .1 second increments will let you fine tune the # of shots per rotation.
Cut discs of whatever material you wish, in whatever size is appropriate for your product.
I'm still early in the deployment phase with this process, and I have only hit one each: shoe store, sculpture gallery, antique shop, box maker, and bakery. No joy.
I'm also trying a work for hire approach with a couple of other commercial photographers, shooting with or for them, for their existing clients, under their studio name.
That might be my preferred M.O. I've got the gear and skills, but I'm short on presentation and business "front".
It's hungry out there.

e2rd,
That's quite a nice pair of movies you've got there.
Have you sold 360 object shoots to any clients?
How much more than a similar, single view shot do you charge?

And here's a Flash version.

I'd appreciate any feedback:
Download times, browser functionality, file size vs image quality.
I'm pretty happy with the lighting, but open to critique.

Yes, Smooth nailed it. Object2VR is the software.
Turntable is powered through a darkroom enlarger timer with a flash trigger in the footswitch socket.
On camera flash (covered with IR filter to make it invisible) triggers studio strobes and turntable movement.
EOS Utility Timer Shooting Tool, does the whole series of ~120 shots, (with a 10 second pause between shots to avoid overheating the strobes), automatically.

I've had great success with a homemade automated turntable.
I bought an AC powered display turntable online for $60.
I used an electronic darkroom enlarger timer, with a footswitch outlet.
I determined which 2 of the 3 wire connections are hot, and connected a flash slave trigger to those. The turntable is plugged into the enlarger outlet, of course.
Now I dial in the time I want the turntable to move between shots. My setup gives 109 steps per rotation at .4 seconds.
I use an on camera flash with an infrared filter on it so it emits no visilbe light, triggering my studio strobes.
There is a tiny delay between when the timer is triggered, and when the turntable starts moving. I think the delay is caused by the power relay in the timer, and it's enough for the flash exposure to complete before movement starts.
I shoot tethered, using Canon's EOS Utility Timer Shooting Tool, setting a generous 10-15 seconds between shots to prevent overheating my old Brownline Speedotrons.
The one drawback to this system that I see, is that the turntable does not index to precise positions. I compensate by shooting lots of images per rotation, so the movements are very small.
